OPERATION
Press the cursor pad for 2 seconds to change to next
language for the message display. Languages in or-
der are: French, German, Italian, Spanish and En-
glish.
The controller default state is AUTOMATIC operation.
If line pressure is adequate and/or the sump pressure
is greater than 5 to 10 psig (0.3 to 0.7 bar), pressing
the ON/OFF pad will put the control in STANDBY
mode until line pressure drops to the programmed
differential value and the sump pressure is low
enough to permit a START. AUTOMATIC mode pro-
vides a timed STOP with automatic restart operation.
Automatic restart after power failure is also included
in AUTOMATIC mode.
MANUAL mode ignores the line pressure permissive
of AUTOMATIC and starts the compressor with ON/
OFF as long as the minimum sump pressure and oth-
er fault conditions are satisfied. The compressor is
only stopped manually with no time stop and no auto-
matic restart after power failure.
Selects bar or psig; use cursor key to select. 1 bar =
14.5 psig.
_C OR _F; use cursor key to select.
Use the cursor key to set the OFF LOAD pressure set-
ting. Depressing the cursor pad for more than two se-
conds will initiate a fast scrolling mode to quickly
reach the desired setpoint for all programmable set-
points. A wraparound feature (on all functions) re-
turns the value to its lowest limit if scrolling exceeds
the high limit. Typically set for 110 psig (7.6 bar).
Selects the OFF LOAD setting by subtracting the dif-
ferential from P2A. Normally set for 10 psid (0.7 bar).
Same as P2A, but provides a second OFF LOAD set-
ting for base/load operation.
Same as P2A, but provides a second ON LOAD set-
ting for base/load operation.
Adjusts timed stop function if compressor is running
in OFF LOAD mode. Adjustment range is 1 to 60 min-
utes.
Adjusts transitions timer for Wye---Delta starters from
0 to 30 seconds. ON LOAD function is delayed by the
value of Wye to Delta time. A separate relay contact is
provided with this function.
A timed contact is furnished to control a condensate
removal solenoid valve. Both the drain duration time
(1 to10 seconds) and the time interval between drains
(1 to 10 minutes) may be set from these modes.
