LC-1000 Lube System Controller
The Trabon microprocessor based LC-1000 Controller
is a multi-use solid state controller that is dedicated to
the operation and monitoring of intermittent operat-
ing series and parallel centralized lubrication systems
equipped with a cycle or pressure switch for cycle
completion feed back.
The LC-1000 monitors and schedules lubrication inter-
vals in either time or stroke/cycle basis in values rang-
ing from 1 to 9999. Pump may be self cycling or single
cycle type requiring a pulsed output.
Four units are available for 12 VDC, 24 VDC, 115
VAC, or 230 VAC operation. The LC-1000 is easy to
program in the field using four mini push-buttons. The
programming requires no special knowledge or training
of computer language. During power down or outage,
all data is saved in EEPROM (Electrically Erasable Pro-
gramming Read Only Memory). As power is restored,
counting and pump status are restored to values prior
to the loss of power.

PROGRAMMING INSTRUCTIONS
The LC-1000 Controller has icons in the display to indi-
cate if the unit is in a lube ON cycle or OFF cycle and to
show the timing mode. They are also used to indicate
which counter is being adjusted when programming new
parameters. The LCD four digit display is used to show
the remaining time left in either an ON or OFF cycle, as
indicated by the icons. Timing can be done in seconds,
minutes, hours or counts. A flashing LCD character
indicates that the timer is in the Programming mode.

e) Press “ENTER” to complete the process (Note:
Monitor period is normally set 2 times the
actual time required for the pump to satisfy the
system cycle requirements).
OPERATION
When power is applied, the green “POWER LED”lights
and the LC-1000 counts down alternately from the
programmed “OFF/ON” Times/Counts to zero.
2. The “OFF” icon will now be blinking.
a) Repeat above process until all “OFF”
options have been programmed.
In the “ON” (Monitor) mode, the ” PUMP LED” lights.
The pump is activated and both the “ON and “RUN”
icons are displayed. If the programmed number of
cycle switch transitions (1/2 cycles) are received be-
fore expiration of the “ON” (Monitor) period, the PUMP
OUTPUT, “PUMP” LED, “ON” and “RUN” icons turn
off and the “OFF” icon will display. If the programmed
number of cycle switch transitions (1/2 cycles) are
not received before expiration of the “ON” (Monitor)
period, a “Fault” will be registered. This suspends
pump operation, turns off the ” PUMP” LED, the “ON
and “RUN” icons, turns on the red “FAULT” LED and
closes the fault output contacts.
b) Press “ENTER” to accept the new values.
3. The “CYCLE” icon will now be blinking
a) Press “ENTER” and the cycle value
(1/2 cycles) will blink.
b) Using the S and X keys set the cycle
value as follows:
Series Progressive:...............02 (1 divider cycle),
04 (2 divider cycles), 06 (3 divider cycles), etc.
Dual Line:................. 01 (half cycle) 02 (full cycle)
Piston Distributor or Injector: .........................01
If a pulsed output to the pump is required, a “PUMP
ON” time may be programmed from 0 to 99 seconds.
Setting this value to zero will provide a steady state
output. “PUMP OFF” is fixed at 3 seconds.
c) Press “ENTER” to register the new value.
4. The “PUMP” icon will now blink.
a) Press “ENTER” again and the pump
pulsed “ON” time will blink.
b) Using the S key and X key, set the value
(seconds) as follows:
The “RUN” icon will display anytime the pump out-
put is energized. During pulsed pump operation, the
“RUN” icon will flash on and off in sequence with the
pump. During continuous running, the “RUN” icon will
not flash.
Self-Cycling Pump
(Motor Driven, or Reciprocating Barrel):......00
Single Shot Pump
(Piston Distributor, or Injector): ...................00
Single Shot Pump
(Recycle for Series Progressive): ........03 to 10
The Controller is programmed to retain the Time/Count
in memory when power is turned off. This feature pre-
vents excessive lubrication in start/stop applications
and retains information for cycle to be completed when
power is restored.
c) Press "ENTER" to accept the new values.
NOTE: In the Recycle mode, PUMP “OFF” time is
fixed at 3 seconds. Press “ENTER” to register
the new value and return to the “DISPLAY”
mode.
NOTE: Scrolling through the modes using the“PRGM”
key only will allow the review of the current
settings without changing any of the values or
timing. It is recommended that programming
not be attempted while a lube cycle is in
process. After making any change in settings,
activate a manual run to initiate the change.
NOTE: Programming examples for specific types of
systems are shown on pages 5, 6 and 7.
CHANGING SETTINGS
From the Timer display mode, pressing the “PRGM”
button will allow you to review or change between the
set “ON” (Monitor), “OFF”, “CYCLE, “PUMP” (Pulsed
On Time) and “DISPLAY” modes. When in the pro-
gramming mode, the icons/digits will blink. When in
the display mode, the icons/digits do not blink.
1. To set a new “ON” (Monitor) Time/Count, press
the “PRGM” key until the “ON” icon blinks. The
current “ON” (Monitor) Time/Count will be
displayed.
a) Press the “ENTER” key. The “ON” (Monitor)
Time/Count digit will blink.
b) Change the value using the S key and X
key.
c) Press the “ENTER” key to accept the new
value. The “SEC/MIN/HR/CNT” icon will blink
d) Press “ENTER” to accept the time base or the
S key to scroll through the timing choices.
MANUAL RUN / RESET
A manual-run lubrication cycle may be initiated by
pressing the manual run button, located on the left
underside of the unit, OR by shorting terminals 14
and 15 together, such as with a remote push-button
momentary switch. Manual run may also be initiated
by pressing S and "ENTER" keys together. Manul run
is also used to reset the controlelr and to clear faults.
