Fig. 18 Green segment right, power supply “on”, iginition
switch open (“off”).
Fig. 19 Green segment left & right are “On”/ Ignition switch
closed (“on”).
Operating mode
• If there is only one segment on in the lower right-hand corner this
indicates that the ignition switch is open. If the ignition switch is
open and the right segment is flashing this indicates a fault condi-
tion. Closing the ignition switch the display will indicate what type
of fault has occurred.
• If the ignition switch opens during a lubricating time the lube cycle
will be completed.
• When switching on the ignition switch, the left-hand segment in
the display window lights up (Fig. 19).
• During the lubricating time of the pump, a circulating illuminated
segment appears in the display window of the membrane key pad
(Fig. 20).
• If the power supply is interrupted during the pause time, the
pause time continues at the point of interruption after switching
power on again.
• If the power supply is interrupted during the lubricating time the
operating time will start at the beginning after switching power on
again.
Segment
• A test display is made when voltage is applied: all seg-
ments and decimal points are illuminated for 2 seconds.
NOTE
EP will briefly appear after the display
test. If EP remains on after the display
test this indicates that the remote lube
pushbutton is in the closed position or
the keypad pushbutton is defective.
When power is applied to the pump the display will indicate if a
pressure switch or pressure transducer is connected to the pump.
The example indicates an internal pressure switch.
There are four possibilities:
S- Internal pressure switch
T- Internal pressure transducer
TT Internal and external pressure transducer (must be
connected)
SS Internal and external pressure switch (must be connected)
