Graco LC-1000 User Manual
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 operating 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 intervals in either time or stroke/cycle basis in values ranging 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 fi eld 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 Programming 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 indicate 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 fl ashing LCD character
indicates that the timer is in the Programming mode.
