9 t (time out) displays. For pressure switch. Press Δto increase
duration of time out required. Large systems may take longer
to pressurize complete system.
NOTE: Test system to establish time out. Add approximately 50%
more to actual time out for system to operate effectively without
timing out before it has reached pressure status.

17 U(vent) displays time in seconds, minutes or hours. Indicates time
needed for system to vent before proceeding into next cycle or
pause time.
SLS can be setup with multiple cycles. For example, if two
cycles are setup, unit operates for one cycle and then goes into
vent time of one minute, as indicated in display. After minute has
elapsed, pump restarts and proceeds with next cycle. When
second cycle is complete, Udisplays and times itself out for
established time. After completing two cycles and vent time,
unit proceeds into pause time.
For this example, one cycle is setup and therefore only
requires a short vent time as no further cycles are required
before reaching pause sequence.
18 Press ENTER to accept vent time (Fig. 26 A).
19 nO displays. Green LED on reservoir illuminates. Option of
low level detection displays. If low level detection is not required,
push Δ and select nO.
20Press ENTER to accept.
21 In this example, low level option is selected.
Press Δuntil YES displays.
22 Press ENTER to accept choice (Fig. 26 B).
Fig. 26
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.

24 Press ENTER to accept choice (Fig. 27 A).
25 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.
26 Select choice and press ENTER (Fig. 27 B).

constant output supply.
28Press ENTER with either choice selected to proceed to next part
of programming (Fig. 28 A).
NOTE
tSt must appear on display before switching off power to unit.
System does not save changes if power to unit is turned off
during any part of programming. tSt must appear on display for
changes to be confirmed.
Fig. 28
29 tSt (test mode) appears in display. Press Δto start turning pump
(Fig. 28 B). 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.
30If all is correct, switch controller power to off and then to on
for unit to proceed into normal mode.

Running system (pump run)
Run (r) time displays when controller is switched on. Time appears
from time set and counts down to zero. Green LED indicates minutes
(Fig. 30). Green LED next to PUMP flashes to indicate pump is
turning or pumping.
NOTE
After each cycle received, amount decreases by one until all
cycles have been received. Unit then proceeds to pause time.

Controller enters pause (P) time when required run time is reached.
Pause time counts down from original setup time to zero and then
resumes run time (Fig. 31). Green LED is steady next to PUMP
indicating pump is on but not turning while in pause mode.
Running system (vent time)
U(vent) displays in sec/min/hrs until required vent time is reached.
Once vent time reaches zero, system proceeds to next cycle (Fig. 32).
