Install the smart relay by following the instructions in the instruction bulletin and the User
Guide. Improper installation may result in failure or malfunction of the smart relay.
z Make the necessary ground and short circuit the connections.
z Check the operating conditions, as described in the User Guide. If you are unsure
of the technical characteristics, contact Schneider Electric.
z Fluctuations or variations in the power supply voltage should not exceed the
tolerance thresholds stated in the technical characteristics, as they may lead to
operating failures and potentially dangerous situations.
z Take any steps necessary to ensure that an application interrupted by a power
failure continues to operate correctly after restoring power and make sure also
that no dangerous situation whatsoever arises.
z Take any steps necessary to prevent involuntary activation of the relay.
z Automation and control devices must be installed in areas where they are
protected against any risk of involuntary activation.
z
Ensure that all connections to the control system meet applicable safety standards.
Ensure that you comply with all applicable standards for emergency stop systems in
order to avoid potentially dangerous situations. Ensure that releasing the emergency
stop system does not cause the automated system to suddenly restart.
z
z Install the smart relay only in environments described in the User Guide. Do not
use the smart relay in environments subject to excessive temperatures, elevated
relative humidity, condensation, corrosive gases, or excessive shocks.
z The smart relay should be used in "Pollution level 2" environments. This level
defines the effect of pollution on the insulation.
z Definition of level 2 Pollution: Only non-conductive pollution arises, except for
occasional temporary conductivity caused by condensation. Do not use smart
relays in environments lower than those specified in IEC Standard 60664-1.
z Use appropriate wires according to current and voltage requirements. Tighten the
screws of the terminal according to the specified torque.
z Use an IEC 60127 approved fuse, in conformity with the requirements for current
and voltage, to protect the power line and output circuits. This is not required
when a device including a smart relay is intended for Europe.
z Use an EU-approved switch. This is not required when a device including a smart

WATCHDOG CYCLE Menu
Description
The duration of a program cycle depends on its length and complexity: In particular,
the type and number of inputs-outputs and the number of extensions.
The program is executed periodically at regular time intervals. This time interval is
called the cycle time.
The program will only execute completely if the cycle time is greater than the
program execution time.
The cycle period is configurable in the : CONFIGURATION → CYCLE
WATCHDOG menu. This period may be set from 6 to 90 milliseconds in 2-
millisecond steps.
The default value of the cycle period is 10 milliseconds.
Illustration:
C Y C L E = 0 5 x 0 2 m S

Menu / OK
Note: Make sure that:
z Input variations that are too rapid are not masked by cycle time that is too slow,
z The speed of output variations is compatibles with system commands.
If the duration of the execution cycle of the program and the embedded software
functions exceeds the cycle time value selected by the programmer, the
WATCHDOG can be used to operate a specific action.
Note: In certain dialog phases, the cycle times are increased by the
communication times between the PC and the smart relay. No guarantee can be
made concerning the real cycle times during this operating mode. The
WATCHDOG is always inhibited in this smart relay operating mode.
Note: To return to the main menu from the CONFIGURATION menu, use the
navigation key

Clock Calibration The quartz that controls the real-time clock of the smart relay has a variable monthly
drift depending on the environmental conditions of the smart relay.
The maximum value for this drift is approximately one minute per month.
To estimate this drift, proceed by observing the drift on the smart relay clock with
respect to a standard reference clock for a few weeks or more.
Example:
If you wish to compensate this drift, you can for example make a -15 second
correction per week to compensate for a + 60 second drift per month. This
compensation is executed on Sunday at one O'clock in the morning.
Note: This correction serves no purpose if the smart relay is subject to long power
interruptions or major variations in temperature.

Introduction
Description
In LD programming mode, an application can be created from the interface of the
front panel of the smart relay.
Here is detailed information on all possible elements of a ladder diagram in LD mode
that are recognized and used by smart relays.
To better understand the functions performed by each element, where necessary a
directly usable example is included.
Composition of
Smart relays accept 120-line diagrams.
Ladder Diagrams
z Each line is comprised of a maximum of 5 contacts.
z
Contacts must be attached to one coil, and the coil is not necessarily on the same line.
Note: When an application requires more than five contacts to activate an action,
the auxiliary relays may be used.

Discrete Inputs
Description
The Discrete Inputs can be used exclusively as contacts in the program.
These contacts represent the status of the input for the smart relay connected to a
sensor (push button, switch, sensor, etc.).
The contact number corresponds to the number of terminals of the associated input:
1 to 9, then A to R (except for letters I, M and O) according to the smart relay and
the possible extension.
Use as a Contact This contact may use the direct state of the input (normally open mode) or its inverse
state (mode normally closed), see below.
Normally open mode:
Symbol of a normally open contact:
I -
A normally open contact corresponds to the use of the direct state of the input. If the
input is supplied, the contact is said to be conducting.
Example: Using a pushbutton to switch a lamp on and off.
I1
Q1
If input 1 is supplied, contact I1 is closed, and coil Q1 is activated.
Normally closed mode:
Symbol of a normally closed contact:
i -
A normally closed contact corresponds to the use of the reverse state (logical
complement of the direct state) of the input. If the input is supplied, the contact is
said to be non-conducting.
Example: Controlling a lamp using an input in reverse state.
i1
[Q1
If input 1 is supplied, contact i1 is open, and coil Q1 is non-activated.

Zx Keys
Description
The navigation keys behave exactly like the I physical inputs (Discrete inputs). The
only difference is that they do not correspond to smart relay connection terminals,
but to the four gray buttons on the front panel.
They are used as pushbuttons, and can only be used as contacts.
Use as a Contact This contact may use the direct state of the key (normally open mode) or its inverse
state (mode normally closed), see below.
Normally open mode:
Symbol of the normally open contact, representing a key:
Z-
The normally open mode corresponds to the use of the direct state of the key. If the
key is pressed, the corresponding input is said to be conducting.
Normally closed mode:
Symbol of the normally closed contact, representing a key:
z-
The normally closed mode corresponds to the use of the reverse state (logical
complement of the direct state) of the key. If the key is pressed, the corresponding
input is said to be non-conducting.
Example
Creating a switch operated by the Z1 key and Q1 output:
Z1 Q1
Each time the Z1 key is pressed, the Q1 output changes state.

Deactivation of
Zx Keys
By default the Zx Keys are active. They may be deactivated in one of the following ways:
z From the smart relay front panel: Using : CONFIGURATION → Zx KEYS menu,
see Zx KEYS Menu, p. 62
z From the programming software: See on-line help of the programming software
for more information.
Note: When the smart relay is in RUN mode, if the Zx Keys have been deactivated,
they cannot be used for inputs in the program, but can be only used for navigating
the menus.

Auxiliary Relays
Description
Auxiliary relays marked M behave in exactly the same way as Q Discrete outputs
(see Discrete (DISCR) Outputs, p. 98), but do not have an electrical output contact.
They can be used as internal variables.
There are 31, numbered from 1 to 9 and from A to Y except for letters I, M, O.
All auxiliary relays can be used, in the program, indifferently either as a coil or
contact. They can be used to latch a state to be used in the form of the associated
contact.

Example
In the following example turning on and off a lamp is conditioned by the status of the
6 following inputs: I1, I2, I3, I4, I5 and IB.
The is on when:
z The I1, I4, I5 and IB inputs are set to the state 1,
and
z The I2, I3 are set to state 0.
Because the smart relay does not allow more than five contacts on a line, auxiliary
relays are used to control the lamp.
You choose to memorize the state of inputs I1, I4, I5 and IB using the auxiliary relay
M1 and memorize the state of inputs I2 and I3 using the auxiliary relay M2. The lamp
is controlled by relays M1 and M2, used respectively as normally open contact and
as normally closed contact.

Discrete (DISCR) Outputs
Description
Discrete Outputs correspond to the smart relay output relay coils (connected to the
actuators). These outputs are numbered from 1 to 9, then from A to G, according to
the smart relay and any extensions.
Any Discrete output can be used, in the program, indifferently either as a coil or a contact.

To use a Discrete output as a coil, four modes are available:
z Contactor mode,
z Impulse relay mode,
z Latch mode,
z Unlatch mode.

SQ-
The Set coil, also called the latch coil, is energized as soon as the contacts to which
it is connected are conducting, then stays set even if later the contacts are no longer
conducting.
This behavior is identical to that of an RS logic flip-flop.
Example: Switching a lamp on and off with two pushbuttons: See Latching Mode
below.
Unlatch mode:
Symbol of a Discrete output, used as a coil in unlatch mode:
RQ-
The RESET coil, also called the unlatch coil, is deactivated when the contacts to
which it is connected are conducting. It remains inactive even if later the contacts
are no longer conducting.
Example: Switching a lamp on and off with two pushbuttons: See Unlatch Mode
SQ1

I1
I2
BPI1 is connected to input I1. BPI2 to input I2. The lamp is controlled by output Q1.
The lamp turns on when pushbutton BPI1 is pressed, and it turns off when
pushbutton BPI2 is pressed.
Note: Output use rule:
z An output may only be used at one single point in the program as a coil.
z If a SET coil is used for a Discrete output, it is advisable to provide a RESET coil
for this output. The RESET coil takes priority over the SET coil.
The use of a Set coil on its own is only justified for activating an alarm signal that
can be reset only by an INIT + ON action from the program.
Note: For reasons of upward compatibility for programs operating with Zelio 1
smart relays, the four types of modes for any given Q output coil or M auxiliary relay
can be used in the same wiring diagram in Zelio 2.
In this case, the operating mode is determined by the coil activated first.

Latching:
By default, if a power break occurs while a timer function block is running, any
information on time already elapsed is lost. When the supply voltage returns, the
time function block is reinitialized and ready for a new operating cycle.
If the application requires it, the time elapsed before the power break can be
memorized using the Latching parameter.
Symbol of the Latching parameter:
Activé
Non activé
This function is used to save the state of the timer's current values and memorize
the elapsed time in the event of a power break.

Example 1
Creating a timer device for a stairway.
The stairway light should remain on for two minutes and thirty seconds when one of
the push buttons is activated.
On each floor, the buttons are linked to the I1 input of the smart relay.
The stairway light is linked to the Q4 output of the smart relay.
You would write the following program:
------I1-------TT1
------I2-------RT1
------T1-------[Q4
To obtain the desired operation, you should use a type B timer (On pulse one shot),
and configure the duration of the timer for 2 minutes 30 seconds. To thus configure
the timer duration, choose the time units M : S and enter the value 02:30 for the

Counters
Description
The Counters function is used to upcount or downcount pulses. The smart relay has
16 timers, numbered from 1 to 9 then from A to G.
The Counters function can be reset to zero or to the preset value (depending on the
chosen parameter) during use.
It may be used as a contact to find out whether:
z The preset value has been reached (upcounting mode TO),
z The counter has reached 0 (downcounting FROM).
Use of Coils
Each timer has 3 associated coils:
z Coil CC: Counting Pulse Input,
z Coil RC: Reset Initial Counter State Input,
z Coil DC: Counting Direction input.
The use of these coils is described below.

Fast Counter
Description
The Fast Counter function is used to count pulses up to a frequency of 1 kHz.
Use of the K1 contact indicates:
z The preset value has been reached (upcounting),
z The value 0 has been reached (downcounting).
The Fast counter inputs are implicitly connected to the I1 and I2 smart relay inputs:
z A pulse (rising edge) on the I1 input increments the counter,
z A pulse (rising edge) on the I2 input decrements the counter.
These inputs should not be used on the wiring sheet.
The Fast Counter function can be reset to zero during use by the RK1 coil. It is reset to:
z 0 if it is in up-count mode towards the preset value
z the preset value if it is in down-count mode from the preset value.
The counter only operates if the TK1 confirmation coil is active.
Repetitive mode can be used with a time-delay value.
Note: Limit overrun:
z
If the current value of the counter exceeds the upper limit: + 32,767, it is set to - 32,768
,
z
if the current value of the counter exceeds the lower limit: -32,767, it is set to +32,768
.
Note: This function block cannot be simulated.

Configuration
The block's parameter settings can be accessed either when entering the command
from Front Panel line or from the PARAMETERS menu if the block has not been padlocked.
The parameters to enter are the following:
z Cycle type,
z Duration of pulse,
z Preset value,
z Type of counting,
z Parameter lock,
z Latching.
Cycle type:
This parameter determines the behavior of the fast counter when it reaches the
preset value (when it is in TO mode), or when it reaches the value zero (when it is
in FROM mode):
The cycle type may be:
z Single: Reaching the preset value (TO mode) or the zero value (FROM mode)
does not affect the current value of the counter.
The current counter value changes on an on-going basis. The output is activated
when the current value is greater than the preset value (TO mode) or when the
current value is less than the preset value (FROM mode).
z
Repetitive: In the TO mode, the current value is reinitialized when it reaches the
preset value and in FROM mode, it is reset to the preset value when it reaches zero.
The output is enabled following this reinitialization and remains active for a time
that may be configured with the parameter: Duration of pulse (from 1 to 32,767
times 100 ms).
Duration of pulse:
Symbol of the Duration of pulse parameter:
I
This parameter is only displayed if the cycle is repetitive. It determines the duration
during which the fast counter remains active when the current value reaches the
preset value (when it is in TO mode), or when it reaches the value zero (when it is
in FROM mode).
This value must be between 1 and 32,767 (x 100 ms).
Preset value:

Modifying the
Mode of a Coil or
a Contact
To modify a contact from the front panel of the smart relay (the programming window
is displayed on the screen), simply:
z Place the cursor over the letter of the contact,
z Proceed as indicated in the paragraph Modifying an element,, p. 44, to scroll
through the possible contact types (A for a normally open contact, a for a normally
closed contact).
Initialization
Example
Status of the contacts and current value on initialization of the program:
z The normally open mode (direct state) is inactive,
z The normally closed mode (inverse state) is active.
A heating resistance is to be triggered by the smart relay Q1 output when the
temperature is below 20° C.
A temperature probe is used, providing a 0 to 10 volt signal for a -10° to +40° C
temperature range. A temperature of 20° C corresponds to a voltage level of 6 volts
on the probe.
You would write the following Ladder program:
A1-------------[Q1
Using the following parameters for the A1 comparator:
A 1
x 1 ≤ x 2
R = 6 . 0
A N A L O G
5
x 1 = I b
x 2 = R

Menu / OK
The comparison operator no. 5 is chosen, that is ≤.
The values to compare are chosen: The analog input IB (to which the temperature
probe is connected) for the first, the reference value R for the second.
The reference value is set to 6.
The analog comparator is thus active when the power measured on the analog input
IB is less than or equal to 6 V. This is when the probe measures a temperature less
than or equal to 20 °C.

Texts
Description
The Text automation function is used to display texts and/or digital values (current
value, preset value, etc.) on the LCD instead of the inputs-outputs screen.
The smart relays have 16 Text blocks, numbered from 1 to 9 then from A to G.
These function blocks are used as coils.
The maximum number of variables that can be displayed per Text block is 4.
Up to 16 Text blocks may be used (TX1 to TXG) simultaneously in one program, but
only the block with the highest number is displayed.
Pressing the Shift and Menu/OK keys in order and simultaneously, switches the

Application
Operation
Using a smart relay means that ordinary switches (with open or closed positions)
can be used in place of two position switches.
The switches are identified as S1 and S2 in the wiring diagram above.
S1 and S2 are connected to inputs I1 and I2 on the smart relay.
The operating principle is as follows: Each time the status of inputs I1 and I2
changes, the status of output Q1 also changes which controls the lamp L1.
The ladder diagram uses basic functions, for example placing contacts in parallel
and in series, as well as the reverse function identified as i1 and i2 (see Using the
Reverse Function, p. 152).
Note: The implementation of a two-way switch is optimum when impulse relay coils
are used (see Discrete (DISCR) Outputs, p. 98).

i1 corresponds to the reverse image of BP1,
pressing BP1 activates input I1, so that the Q1 pressing BP1 activates input I1 and
output is activated and the lamp L1 turns on.
therefore contact i1 is disabled, output Q1 is
disabled and the lamp L1 turns off.

Introduction
Module in RUN
Mode
Once an application has been entered in ladder diagram form, debugging tests still
must be run.
The first step is to set the smart relay to RUN. To do this, in the RUN/STOP option
in main menu and select RUN.
From this moment on, the smart relay handles the physical inputs and outputs
according to the instructions entered in the ladder diagram.

Smart Relay Reaction to a Power Failure
Description
A power failure may cause the smart relay to restart and lose any data not saved.
Smart relays have the ability to save the current time for at least 10 years.
In addition, it is also possible to back up the variables configured with the Latching
option defined in the parameters window.
Latching
The Latching function is used to save the state of the counter’s current values in the
event of a power failure.

Sample Application
Specifications
Objective
We wish to complete and centralize the control of the underground car park of an
administrative building.
Automatic Gate
The entrance and the exit of the car park are controlled by an ordinary automatic gate.
The gate has the usual basic features such as:
z Gate timing (opening and closing) by passing vehicles,
z Ticket payment management,
z Safety telephones,
z External control for locking in closed position, etc.
Counting
Vehicles
In addition, we would like to keep track of vehicles parked in the facility.
We would thus be able to control a lighted panel that informs drivers when all parking
spaces are occupied and prevents access by locking the gate in the closed position.
Drivers would then know to look for a parking space elsewhere.
It must also be possible to override this function when necessary to allow access for
emergency services (fire department, emergency medical service, etc.).
Open Time
We would also like to prevent access to the facility when the building is closed.
Security personnel should be allowed to prevent the gate from locking in non-ordinary
circumstances. The hours of opening are the following: Monday to Friday from 8:30
am to 5:30 pm, Saturday from 9:30 am to 12:00 noon and closed all day Sunday.
RemovalofToxic For safety reasons, it is also necessary to remove toxic emissions such as carbon dioxide
Gasses
by using a fan when the measured concentration levels exceed permissible levels.
A specialized sensor will be used that provides an output value between 0 and 10V.
Lighting
There is also a requirement to control lighting, triggered by a vehicle arriving and via
pushbutton switches placed near all of the pedestrian access points.
To save energy, lights will turn off after 10 minutes. This is the length of time
generally observed for someone to park and exit their vehicle and take the elevator,
or return to their vehicle and exit the park facility.
Manual Counting In addition, a manual action should be able to provide current information on the
number of vehicles parked in the facility. Someone should be able to manually
increase or decrease the number of vehicles known by the smart relay.

becomes full (no spurious detection or counting actions take place if vehicles are
allowed to enter by manual release).
Note: For a given counter, the coils CC and DC should only appear once in a
ladder diagram.
In addition, output Q2 is activated when entry into the car park is not allowed. This leads to the
use of an auxiliary relay to manually lock or unlock the access gate using the navigation keys.
