SERVICE DUE COUNTDOWN TIMER


If the service due countdown timer reaches 0 (Zero) hours the Service
and Alarm symbols will flash and the service Alarm (Warning) code will be
displayed. The Alarm code can be reset but the service symbol will remain on
the display until the service due timer is reset; the service hours will continue
to decrement in negative hours. The service countdown timer can be reset,
using the menu routine, when the required service has been carried out. Set
to any value greater than 0 (Zero) hours before reset.

MENU ROUTINE

Press Enter to increment to the second code
character.
When all four character has been set, and the
last code character is flashing, press Enter. If
the access code is correct for the access to one
of the two menus the first menu item of the


The compressor will maintain pressure between the set Pu (Unload Pressure
Set Point) and (PL) (Load Pressure Set Point). When Pressure reaches the set
'Pu' level the compressor will unload. When pressure falls to the 'PL' level the
compressor will load.
NoTE:
•

•
•
When the main motor stops the compressor will allow a period of blowdown
(the Blowdown Time) before a motor start can be re-initiated. A motor
re-start is inhibited during this time period. This time is intended to allow
internal pressure (or sump pressure) to be vented before a motor start
sequence is permitted. Set to 0 (zero) seconds if not required.
•
When the Stop button is pressed the compressor will unload and the main
motor will continue to run for the set Stop Time. This time is intended to
allow internal pressure (or sump pressure) to reduce before the compression
element is stopped; preventing potential oil blow-back through the
compression element and air filter. The stop time is initiated from the
moment the compressor is unloaded. If the compressor has been offload for
a period of time prior to a stop command the time is automatically reduced
accordingly. If the compressor is stopped after the compressor has been
running offload for the stop time, or longer, the compressor is stopped
immediately; no stop time is applied. Set to 0 (zero) seconds if not required.
