PRODUCT INFORMATION  
Control Battery Storage and Charging  
Introduction  
Service Information S280-79-10 provides installation and  
operation instructions for the Kyle Form 5 and Form 5  
UDP microprocessor-based electronic recloser controls.  
The 24 Vdc control battery in the Form 5 control is fully  
charged prior to shipment and is ready for use. In order to  
maintain sufficient charge to operate the control, the  
sealed lead acid battery should be charged after no more  
than three months of storage.  
Read This Manual First  
Note: Two 12 Vdc, 13 amp-hour batteries are available for  
use with the Form 5 Distribution Automation upgrade  
accessory.  
Read and understand the contents of this manual and fol-  
low all locally approved procedures and safety practices  
before installing or operating this equipment.  
Temperature has an effect on battery life. Sealed lead  
acid batteries should be stored, fully charged, at room  
temperature. Never store lead acid batteries at tempera-  
ture exceeding 47°C (117°F), as damage can result in  
approximately one month.  
Additional Information  
These instructions cannot cover all details or variations in  
the equipment, procedures, or process described, nor  
provide directions for meeting every possible contingency  
during installation, operation, or maintenance. When  
additional information is desired to satisfy a problem not  
covered sufficiently for the user's purpose, please contact  
your Cooper Power Systems sales representative.  
IMPORTANT: To maintain sufficient charge to oper-  
ate the control and prevent battery cell damage, the  
sealed lead-acid batteries should be charged after no  
more than three months of storage.  
ANSI Standards  
Kyle reclosers are designed and tested in accordance  
with the following ANSI standards: C37.60 and C37.85  
and ANSI Guide C37.61.  
To keep the battery charged, energize the control’s built-  
in charger with AC power applied to the user AC supply  
input connector block TB1, located left of the RIF module  
within the control cabinet.  
Note: When shipped from the factory, the battery source is  
disconnected and its output plugs are taped to the cab-  
inet. Connect the battery plugs into the mating connec-  
tors to complete the battery circuit.  
Quality Standards  
ISO 9001:2000-Certified Quality Management System  
Acceptance and  
Initial Inspection  
Each Form 5 control is completely assembled, tested, and  
inspected at the factory. It is carefully calibrated, adjusted  
and in good condition when accepted by the carrier for  
shipment.  
IMPORTANT: Connect the control battery when AC  
power is connected to the control’s AC supply Input Ter-  
minal Block. The battery must be disconnected prior to  
shipping or storing the control.  
Upon receipt, inspect the carton for signs of damage.  
Unpack the control and inspect it thoroughly for damage  
incurred during shipment. If damage is discovered, file a  
claim with the carrier immediately.  
Battery Replacement  
The 24 Vdc control battery has a life expectancy of 4 to 6  
years. It is recommended that the battery be replaced  
after 4 years.  
Handling and Storage  
Control Power  
Be careful during handling and storage of the control to min-  
imize the possibility of damage. If the control is to be stored  
for any length of time prior to installation, provide a clean,  
dry storage area. If storage is in a humid atmosphere, make  
provisions to keep the control circuitry energized.  
The primary source of power is factory configured for 120 Vac  
or 240 Vac. The 240 Vac version is available as an option  
at time of order entry. Primary power is rectified to charge  
the power capacitor and to power the dc/dc converter that  
provides power to the control. A minimum of 500 mA of ac  
current is required for heater operation, battery charging  
current, and to keep all modules energized.  
Note: To energize the control, apply AC power to the AC sup-  
ply input connector block TB1 located left of the  
Recloser Interface (RIF) module within the control.  
Refer to the Customer Connection for AC power sec-  
tion in this manual.

Kyle Form 5, Form 5 UDP, Form 5 DC NOVA Recloser Control Installation and Operation Instructions  
The AC power LED indicator on the operator panel of the  
AC Reclosers  
control will turn off after 15 seconds upon loss of AC  
power. The indicator will illuminate immediately upon  
return of ac power.  
Power to operate the tripping and closing solenoids in the  
recloser is provided by the power capacitor located  
behind the operator panel of the control. A sealed, 24-volt,  
lead acid battery is located in the lower portion of the con-  
trol cabinet and is utilized to provide operating and trip-  
ping energy when AC power is temporarily lost. The  
control is equipped with an ac-powered, temperature-  
compensated battery charger.  
Initializing the Control  
Two methods are available to initialize the Form 5 control.  
Method 1: Connect AC power to the input connector ter-  
minal TB-1. Refer to the Customer Connec-  
tions for AC Power section of this manual.  
Operation Upon Loss Of AC Power  
Method 2: Connect the battery terminal on the control  
and press the MANUAL BATTERY RECON-  
NECT button located on the Form 5 power  
supply. See Figure 4.  
If the control is equipped with the standard 24 Vdc lead-  
acid battery, the control maintains full operation from the  
battery power supply for a minimum of 32 hours at 20°C  
(24 hours at -40°C). To prevent battery damage, the con-  
trol shuts down automatically upon detection of low bat-  
tery voltage below 22.7 Vdc.  
Note: Method 2 powers the control off the battery  
and is not intended for long term operation.  
In both methods, after initialization, set the control clock  
via the interface software.  
Control programming settings and parameters—including  
event recorder, duty monitor, and data profile metering  
parameters—are stored in non-volatile memory and  
retained upon loss of control power. The time/date clock  
resets to 0:00:00, 1970 upon loss of control power.

S280-79-10  
FORM 5 CONTROL DESCRIPTION  
Current sensing is provided by three current transformers  
located in the recloser and interfaced to the Form 5 control  
via the control cable. This cable also supplies Trip, Close,  
and Recloser status, and connects to the Recloser Inter-  
face (RIF) module to provide isolation for reliable opera-  
tion. Voltages for metering are also connected to the RIF  
module via the connector terminal block, TB-1 (Figure 3).  
The following chain of events occurs for an operating  
sequence of two trips to lockout:  
1. The overcurrent signal is integrated with time on the  
selected curve for the first trip operation (TCC1) to  
produce the signal which energizes the trip circuit.  
2. Energizing the trip circuit connects the battery and  
capacitor to the trip solenoid to open the recloser.  
A functional block diagram of the Form 5 control is shown  
in Figure 3. Line current flowing through the recloser is  
converted by the CPU module to a digital signal suitable  
for metering and fault current calculations. Data sampling  
occurs at a rate 32 times per cycle. The CPU contains a  
data acquisition section that uses the acquired samples to  
compute the fundamental currents and voltage for use in  
overcurrent, under/over voltage and under/over frequency  
protection, as well as currents and voltages for metering  
functions. The current for overcurrent protection is calcu-  
lated on a sub-cycle basis; it includes only the fundamen-  
tal and DC component. For metering, the fundamental and  
harmonic current and voltages are determined.  
3. Upon opening, the control starts timing on the first  
reclosing interval-delay time.  
4. Upon expiration of this reclosing interval-delay, a clos-  
ing signal is issued from the control, closing the  
recloser and selecting the time-current characteristics  
for the second trip operation (TCC2).  
5. If current remains above the minimum-trip level, the  
tripping and reclosing sequence is repeated.  
6. The control begins the reset-delay timer if the over-  
current is cleared before the operating sequence  
reaches lockout indicated by a closed recloser and  
current below minimum trip.  
When the phase or ground current exceeds its pro-  
grammed minimum-trip value and associated time-cur-  
rent curve (TCC) timing, the control initiates the  
programmed sequence of recloser tripping and reclosing  
operations via the CPU and RIF modules. If the fault is  
temporary, the control ceases to command recloser oper-  
ations after a successful reclose, and the control resets to  
the start of its operating sequence after a preset time  
delay. If the fault is permanent, the control performs its  
complete programmed sequence of reclose commands  
and locks out with the recloser open. Once locked out, the  
control must be closed via the operator panel or SCADA  
communications. This resets the control to the start of the  
operating sequence.  
7. When the reset-delay times out, the control is reset to  
the home state and is ready for another programmed  
operating sequence. If current rises above minimum  
trip prior to the reset-delay timing out, the timer is  
halted and the control resumes the operating  
sequence while the accumulated reset-delay timing is  
restarted.

Kyle Form 5, Form 5 UDP, Form 5 DC NOVA Recloser Control Installation and Operation Instructions  
The Form 5 control is constructed in a modular fashion to  
Central Processing Unit (CPU)  
simplify service and the addition of accessories (Figure  
4). The standard configuration incorporates a Central  
Processing Unit (CPU) module, power supply module,  
Recloser Interface (RIF) module, and an operator panel.  
Module  
The CPU module is the center of the Form 5 control. The  
CPU contains a 32-bit micro-controller, a Digital Signal  
Processor, RAM and EEPROM memory, and a 16-bit  
analog-to-digital converter. The CPU module accepts 16  
analog inputs which it routes through the digital signal  
processor, which samples 32 times per cycle, to compute  
harmonic analysis to the 15th harmonic.  
Discrete Interface (DIF) module(s), the fiber-optic board  
and the RS-232 communication interface cards may be  
ordered as accessories. Mounting provisions can be  
provided to add customer-supplied radio and modem  
modules.  
Discrete Interface (DIF) Module  
Recloser Interface (RIF) Module  
The Discrete Interface (DIF) module allows users with  
existing RTUs the ability to interface with the Form 5 con-  
trol. The DIF module contains 12 inputs and 12 outputs  
can be customized for a remote or supervisory function.  
One Form 5 control can accommodate two DIF modules.  
See DISCRETE INTERFACE (DIF) ACCESSORY sec-  
tion of this manual.  
The Recloser Interface (RIF) Module provides the inter-  
face between the recloser and the CPU module, as well  
as the interface between the voltage sensors and the  
CPU module. The RIF is designed to interface with the fol-  
lowing reclosers: WE/WVE group, NOVA group,  
VSA/VSO group, and KFME/KFVME (50Hz) group.  
The recloser connector includes three current-trans-  
former inputs, Open and Closed status sensing, and Trip  
and Close controls. The voltage sensor connector  
accepts six voltage inputs; three for source-side, and  
three for load-side voltage. Two sets of dip switches,  
located on the RIF front panel, utilize different switch posi-  
tions to configure the desired voltage. See Figure 17.  
Power Supply Module  
The Power Supply module is designed to accept 100 to  
134 Vac or 200 to 268 Vac user-supplied input power at  
either 50 or 60 Hz.  
The Power supply module (connection P9) provides aux-  
iliary power to radio communications units, RTUs and  
other accessories. The auxiliary output provides 24 Vdc  
(12 Vdc is available) for user loads. The auxiliary power  
supply has the capability to provide a load of up to 40 W  
peak (1 second) and 3 W average. The auxiliary power is  
fused and current-limited to prevent user loads from dis-  
abling the control.  
The RIF board accepts either 12, 120, or 240 Vac voltage  
inputs for metering. The factory configuration is outlined  
on the module label and can be customized to user spec-  
ification. See RECLOSER INTERFACE (RIF) MODULE

screens of information, with each display containing four  
lines of information, with up to 20 characters per line.  
Access to the screens is obtained through navigational  
keys which permit the user to scroll through the menu in a  
timely and efficient manner.  
Pressing and holding the CHANGE/LAMP TEST key for  
three seconds will cause the control to perform a front-  
panel lamp test. In the Lamp Test Mode, the status indi-  
cators flash three times (one second on, one second off).  
All status indicators then return to their previous state.  
While in the Lamp Test Mode, the control response to  
operator panel keys is disabled, except for the TRIP  
(LOCKOUT), CLOSE, and HOT LINE TAG switches.  
When an overcurrent trip occurs, the control automatically  
displays the fault current values as shown on the LCD dis-  
play as Screen 1. Refer to LCD Display Screens section  
of this manual.

NON RECLOSING  
HOT LINE TAG Switch  
Non-reclosing mode disables any automatic reclosing  
operations. Non-reclosing does not alter the active TCC.  
The feature is activated by pressing the CHANGE/LAMP  
TEST key, then pressing the NON RECLOSING key. The  
red indicator illuminates.  
WARNING: Hazardous voltage. Do not use Hot  
!
Line Tag as a substitute for a visible disconnect.  
Always establish a visible disconnect prior to perform-  
ing any work requiring a de-energized line. Failure to  
comply may cause death, severe personal injury, or  
SUPERVISORY BLOCKED  
equipment damage.  
T276.0  
Supervisory Blocked disables supervisory SCADA and the  
interface software; remote SCADA remains active. Opera-  
tional data and metering information are available while  
the control is in the SUPERVISORY BLOCKED position.  
The TRIP and CLOSE pushbuttons are active indepen-  
dently of the SUPERVISORY BLOCKED function.  
Hot Line Tag is provided for live-line work applications. All  
closing operations are disabled when the Hot Line Tag  
feature is activated. While active, the control utilizes an  
independent, user-selectable time-current curve for trip  
operations.  
Activation of the feature is restricted to the operator panel  
keypad by pressing the CHANGE/LAMP TEST key, then  
pressing the SUPERVISORY BLOCKED key.  
IMPORTANT: Hot Line Tag activation does not  
cause the recloser to trip open. It only prevents the  
recloser from closing.  
COLD LOAD PICKUP BLOCKED  
The Cold Load Pickup feature is blocked while the COLD  
LOAD PICKUP BLOCKED is active. When CLPU is not  
blocked, the control utilizes the Cold Load Pickup TCC,  
reclose interval, operations to lockout and minimum trip set-  
tings in lieu of the normal first operation protection settings.  
IMPORTANT: Hot Line Tag is intended solely for  
live-line work applications, such as maintenance,  
repairs or improvements to the distribution system, that  
occur while the line remains energized.  
Note: The Cold Load Pickup Blocked key is replaced by the SEN-  
SITIVE GROUND FAULT key on international controls.  
The Hot Line Tag feature (Figure 8) consists of a toggle  
switch and an LED indicator which illuminates when the  
function is active. When active, Hot Line Tag prevents all  
closing attempts and shifts protection to one trip to lockout  
on the programmed time-current curve. The Hot Line Tag  
function takes precedence over Cold Load Pickup, Non  
Reclosing, and Fast Trips Disabled.  
BATTERY TEST  
Depressing the BATTERY TEST key performs a control  
battery test. The red indicator illuminates and turns off  
automatically when the control has finished performing the  
test. Refer to the Battery Test Procedure section of these  
instructions for further details on testing the control battery.  
Activation is accomplished by placing the operator panel  
toggle switch to the ON position, or via SCADA command.  
Hot Line Tag is activated from the operator panel, com-  
munication Port 2, communication Port 3, or a Discrete  
Interface Module (DIF). All sources must be off to de-acti-  
vate Hot Line Tag.  
FAST TRIPS DISABLED  
Fast Trips Disabled commands the control to use the pro-  
grammed Fast Trips Disabled time-current curve for all  
tripping operations.  
ALTERNATE PROFILE Indicator/Key  
The Hot Line Tag feature may only be reset by the source  
which initiates the function. For example, if Hot Line Tag  
is activated at the operator panel, resetting the function is  
only possible at the operator panel, and not via SCADA  
command. For SCADA, Hot Line Tag must be disabled  
via the same port number where Hot Line Tag was origi-  
nally enabled.  
The control has four separate protection profiles; a normal  
profile, and Alternate Profiles 1, 2, and 3. Each profile  
changes all protection parameters for the control. Except for  
the normal profile, each has an indication and selection key.  
During control operation, if the three alternate profile indica-  
tor lights are not illuminated, the normal profile is active.  
To select an alternate profile, press the CHANGE/LAMP  
TEST key, then press the desired alternate profile. To  
return to the normal profile, simply turn off the active alter-  
nate profile. These functions can also be operated  
remotely via communications interfaces.  
Note: Program all protection profiles. Program unused alter-  
nate profiles should be programmed with the same set-  
ting as one of the applicable profiles. Default settings on  
unused alternate profiles can cause unnecessary out-  
ages if they are below normal system requirements.  
Note: The minimum trip values for each protection profile are  
shown on Screens 32 and 33 of the LCD display. Check  
these minimum trip values prior to changing an alternate  
profile to avoid misoperation of the control under load  
conditions.

Kyle Form 5, Form 5 UDP, Form 5 DC NOVA Recloser Control Installation and Operation Instructions  
RS-232 Communication Port  
Control Features  
The standard Form 5 control is equipped with a operator  
panel RS-232 port for interface with a personal computer  
running the Form 5 interface software program. This nine-  
pin female data communication equipment (DCE) Port 1  
permits the uploading of all programming information  
stored in the control, including protection profiles, event  
recorder, data profiles, alarms, counters, and metering  
information. Port 1 provides a simple means to download  
operating parameters from a personal computer to the  
control.The protocol, baud rate and address for Port 1 are  
identified from the LCD display.  
The Form 5 recloser control offers numerous standard  
features and accessories that allow the user the utmost  
flexibility in designing a control suitable for their applica-  
tion requirements.  
Under/Over Frequency Loadshedding  
The Form 5 control includes provisions for frequency  
loadshedding that trips the recloser for conditions of under  
or over system frequency. Access to this feature is  
through frequency threshold, trip time, and allowable volt-  
age threshold.  
If a fiber-optic or RS-232 accessory board is connected to  
Port 2 (located on the back of the operator panel) any  
external electrical connection from the operator panel will  
disable the accessory board.  
With the auto-restoration feature, the Form 5 can be set to  
close the recloser after the system frequency and voltage  
have recovered. Parameters available for setting include  
frequency and voltage thresholds and time delay.  
Note: The operator panel RS-232 port is intended only for  
temporary connection of a personal computer. Perma-  
nent serial communications must be made via the RS-  
232 or fiber-optic accessory board.  
A frequency alarm is available and can be configured for  
notification.  
Voltage Protection (120 Vac-based)  
Battery Test Procedure  
The condition of the control battery is tested by depress-  
ing the BATTERY TEST hot key on the operator panel. No  
external current/voltage meter is necessary for testing.  
Voltage protection functionality is included as standard on  
all Form 5 controls. A recloser trip will be issued for under  
and over voltage conditions when the monitored voltage  
falls outside user-specified limits for a selectable time.  
Response mode includes any single-phase, all three  
phases, and single-phase with three-phase inhibit.  
Response mode facilitates protecting against a single  
phase condition common when a high side fuse operates  
on a distribution transformer. Parameters are also avail-  
able to provide auto restoration after a trip. A voltage  
alarm is available and can be configured for notification.  
The control performs a self-test every 12 hours or when  
initiated by an external command. When a battery test is  
initiated, the spurious charge is first drained to allow the  
battery voltage to equalize. A 10-ohm, 55-watt resistor is  
then placed across the battery terminals and a voltage  
drop is calculated. If the drop from the equalized voltage  
to the test voltage exceeds 2 volts, then the CHECK BAT-  
TERY LED is illuminated.  
Protection Profiles  
To perform a battery test:  
Four separate protection profiles are included to allow the  
user to adapt overcurrent settings for varying system con-  
ditions such as load, live line work or weather. The active  
profile is selected from the operator panel or with the inter-  
face software or SCADA (Figure 9). Each profile has 14  
TCC specifications plus reclose intervals, sequence coor-  
dination and reset times to maintain independent protec-  
tion parameters.  
1. Using the Next and BACK keys, scroll through the  
LCD display to Screen 31, the Battery Monitor screen.  
2. Record the NORMAL VOLTS and NORMAL CUR-  
RENT readings from the screen.  
Note: Voltage should be between 25 to 31 volts with  
higher readings at colder temperatures. Under nor-  
mal conditions with ac connected and the battery  
trickle charging, the current should read less than  
20 mA. With ac connected and in bulk charging  
mode, current will range from 12 to 600 mA. With ac  
disconnected and the battery supplying the load,  
current will read -180 mA to -600mA depending on  
accessories connected.  
3. Momentarily, press the CHANGE/LAMP TEST key,  
then BATTERY TEST key.  
Note: AC power can be either connected or disconnected  
for Step 3.  
4. Record the TEST VOLTS reading from the LCD and  
the status of the CHECK BATTERY LED. Service the  
battery if the CHECK BATTERY LED is illuminated.

Trip Failure Detection  
The Trip Failure Detection feature is an internal diagnos-  
tic alarm for verifying the proper operation of circuit trip-  
ping and fault clearing of the recloser. Trip Failure  
detection indicates the recloser has failed to trip all  
phases following a trip signal from the control. Failure to  
trip is assumed if a current of at least 10 Amps is detected  
approximately 2 seconds after the trip signal is initiated.  
IMPORTANT: The recloser must be isolated and de-  
energized immediately upon detection of trip failure.  
Follow proper procedures and safety practices to iso-  
late and de-energize the recloser.  
Upon activation of the feature, these four LEDs flash 1  
second on, 1 second off (Figure 10):  
The Trip Failure Detection alarm may be triggered from  
many potential sources including mechanical, electrical,  
control, or interrupter failure. Interrupter failure may  
include loss of vacuum in a vacuum interrupter.
