Input Indicator Ch0 Description
11 Spare
12 Turns off if motor overload relay contact OL1, OL3, or OL5 opens indicating
that the respective pump motor 1, pump motor 2, or the supercharge pump
has tripped its respective overload. This event indicates excessive current
draws.
13 Turns on if motor relay M5 closes to show the supercharge pump is running.
14 Turns on if motor relay M2 closes to indicate pump motor 1 is running.
15 Turns on if motor relay M4 closes to indicate pump motor 2 is running.
16 Turns on if remote start is initiated.
17 Turns on if remote run is initiated.
18 Turns on if remote high pressure is initiated.
19 Turns off if switch FS1 opens to indicate that the fluid level has dropped
below a preset limit.
20 Turns on if inlet pressure switch PS1 (30 psi) closes prior to start up of the
main pump(s). Inlet pressure is supplied by the supercharge pump.
21 Turns off if
∆
P switch PS2 opens to indicate the fine filter is dirty.
22 Turns off if switch TAS1 (140
°
F) opens to indicate that the hydraulic fluid
temperature has exceeded a preset limit.
23 Turns off if switch TAS2 (100
°
F) opens. When fluid temperature exceeds a
preset limit, TAS2 opens to energize water inlet solenoid SOL4. SOL4 opens
the optional water regulation valve, letting water into the heat exchanger.
