7 t (time out) for pressure switches displays. Adjust by pressing Δ
to required time. Large systems time out is substantially greater
than smaller systems. Time out, or dwell time, is actual time it
takes pressure switch to close contacts. When pressure switch
closes, signal is sent to controller that system is pressurized.
Should a pipe break, pressure switch remains open. This is a
safety and control feature to indicate to controller when system
can change over. Time out setting in PROXY 1 will apply by default
for that of PROXY 2 when using two pressure switches system.
8 Press Δto increase time out.

24 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.
25 Select choice and press ENTER (Fig. 27 A).
26 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.
27 Press ENTER with either choice selected to proceed to next part
of programming (Fig. 27 B).

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. With external warning lamp, press ∇and LED will
either flash or show steady, indicating external device is working.
29 If all is correct, switch controller power to off and then to on
for unit to proceed into normal mode. Red setup LED will not

Run mode
Unit proceeds in run (r) mode after power is terminated on unit and
then switched on again. All devices selected are displayed (Fig. 29).
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. 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.

Pause (P) 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 cycles)
In dual-line system, when U(vent) displays, pump stops pumping
until line A or B pressure switch opens or line is totally vented.
As cycles complete, cycle count in Udisplay counts down (Fig. 32).

Cycle begins to pump lubricant through line B. As line begins to
pressurize, pressure switch closes. Green LED on controller
illuminates. Pump continues to pump until it reaches pressure set
on change-over valve. At this stage, pressure switch remains closed.
Stage 2
As pressure reaches change-over valve, direction of flow changes.
Grease in line A begins to pressurize while line B vents. As line A
reaches 290 psi (20 bar), pressure switch closes and shuts pump off
until line B is totally vented. Pressure switch in line B must be open
before cycle will continue. Both LEDs illuminate.

Stage 3
As line B vents, pump continues to pressurize line A until it reaches
pressure setting of change-over valve. LED for line A pressure switch
remains on in this process. In display, rindicates cycles set have not
yet been completed.
Stage 4
As pressure reaches line A, it switches over change-over valve and
changes direction of flow. Line B begins to pressurize until it reaches
290 psi (20 bar). As pressure switch in line B closes, pump stops and
waits for pressure switch on line A to open. Both LEDs illuminate.
U2 (vent) shows in display and indicates two cycles remaining.
1) Set at 5 076 psi (350 bar).
2) Set from 290 to 580 psi (20 to 40 bar).
