(Fig. 28 A). Green LED flashes next to PROXY 1 indicating sensor
part of setup procedure.
3 Press ENTER to select YES and PROXY 1 enters setup procedure.
4 t (time out) appears in display indicating alarm will activate if
sensor does not send signal to controller within set time. This
function is used when flow proximity sensor is installed on feeder.
Within feeder, piston activates sensor and sends signal to
controller. Controller resets time out and starts counting down
to start monitoring process. This function continues to work while
in RUN mode. Set time out greater than cycle time of specific
feeder. This depends on type of pump being used.
Press Δto increase time out to desired setting.
5 Press ENTER to confirm. In example, time out of 5 seconds is
confirmed (Fig. 28 B).

14 Press ENTER to confirm.
15 For this example, press Δuntil YES appears in display.
16 Press ENTER to confirm (Fig. 30 B).
17 n-O (normally open) appears in display.This indicates sensor is
normally open or normally closed. Press Δto choose between
n-O or n-C.
18 Press ENTER to confirm choice (Fig. 30 C).
NOTE
10-second delay occurs on startup when using low level sensor
to ensure paddle assembly is in correct position.
Sensor activates on low level after 10 seconds. Low level
warning displays when unit reaches pause status.
Fig. 31
19 FE (fatal error) or nFE (nonfatal error) appears in display.
Option FE (fatal error) is used to stop pump on low level warning.
Typically used on pumps with reservoir capacities from 0.26 to
2.6 gal (1 to 10 l). It is preferred to stop pump at low level to
maintain layer of grease above pump element area thereby
not allowing air pockets to form around pump element when
filling up reservoir. Option nFE (nonfatal error) is recommended
on larger pump reservoirs with substantial distance from pump
tube to bottom of reservoir.
20Select choice and press ENTER (Fig. 31 A).
21 L - F (lamp flashing) displays. This option is used with external
warning lamp. Typically, if monitoring is installed, this function is
used. Press Δand change status from L - F (lamp flashing) to
L - S (lamp static). L - F is a pulsed output supply and L -S is a
constant output supply.

Running system (pump run)
Run (r) time displays when controller is switched on. Time appears
from actual time set and counts down to zero. Green LED indicates
minutes (Fig. 34). Green LED next to PUMP flashes to indicate pump
is turning or pumping.
Running system (pump pause)

23 tSt (test mode) appears in display. Press Δfor pump to start
turning (Fig. 32). Correct pump from turning in wrong direction
by changing polarity of wiring. Check other sensors by energizing
them manually and observing if green LED illuminates. If LED
does not illuminate, a problem exists with wiring or setup
procedure.
24 If all is correct, turn off power supply to controller
NOTE
tSt must appear on display before switching off power to unit.

Progressive-line system with reservoir monitoring using run cycle counter
1 Refer to steps 1–5 on pages 10.
2 To use rCC (run cycle counter), select ∇(Fig. 36 A).
If Δis pressed by accident, continue to press Δuntil rCC displays.
During run cycle, controller looks for signal from proximity
sensor normally fitted to feeder system ensuring complete
machine is lubricated adequately.
Some calculation is necessary to calculate cycles required
through specific feeder system used.
3 t (time out ) appears in display indicating alarm will activate if
sensor does not send signal to controller within set time. This
function is used when flow proximity sensor is installed on feeder.
Piston activates sensor within feeder and sends signal to
controller. Controller resets time out and starts counting down to
start monitoring process. This function continues to work while in
run cycle mode. It is important to set time out greater than cycle
time of specific feeder. This also depends on pump being used.
Press Δto increase time out to desired setting.
4 Press ENTER to confirm (Fig. 36 B).
In example, time out of 45 seconds is confirmed.
5 n-O (normally open) appears in display. This indicates if sensor is
normally open or normally closed. Press Δto choose between
n-O or n-C.
6 Press ENTER to confirm choice (Fig. 37 A).
7 Press ENTER again to confirm use of run cycle counter
(Fig. 37 B).
8 Press Δto increase number of cycles required (Fig. 37 C).
Remember 1 cycle represents complete cycle of feeder.
For example, should 6 port feeder be used, 1 cycle indicates
feeder has lubricated all 6 points. 1 cycle is not equal to 1 minute
run time.The larger the feeder, the longer it takes to reach 1 cycle
9 After selecting amount of cycles, press ENTER to confirm.

Run mode
Unit proceeds in run (r) mode after power is terminated on unit and
then switched on again. All devices selected display. After each cycle
received, amount decreases by 1 until all cycles have been reached
and unit proceeds to pause time.
Running system (pump run)
When controller is switched on, run cycle counter (rCC) appears in
display. Counter appears from actual counts set and counts down to
zero. Green LED indicates run cycle counter. Green LED on PUMP
flashes indicating pump is turning or pumping.
Running system (pump pause)
Controller goes into pause time when required cycle count is
reached. Pause (P) time counts down from original setup time to
zero and then resumes cycle count. Green LED next to PUMP is
steady to indicate pump is there by not turning while in pause mode.
