6.9 Run-On Timer
In line with Champion Compressors philosophy of keeping energy
consumption to a minimum, the compressor electronic controller provides a
Run-On Timer function. This function monitors the length of time that the
compressor runs without actually compressing air. If this period exceeds the
pre-set time (usually set to six minutes), the compressor will enter Standby
mode, and will automatically restart if a fall in system pressure is registered.
This mode is indicated by the electronic controller displaying “STANDBY RUN
ON” whilst still running, and “STANDBY” once stopped.
The factory setting of this timer is six minutes, but it may be adjusted between
zero and ten minutes in accordance with specific installation requirements to
ensure that the compressor does not exceed six shut downs per hour.
Adjustment is via the user menu structure in the electronic controller (refer to
the “Electronic Controller Advanced Configuration” manual available from
Champion Compressors Customer Support Division for details on this
procedure). Please refer to Champion Compressors Customer Care Division
prior to any adjustments being made, as an incorrect setting may result in
damage to the compressor.
Warning: Never assume that the compressor has completely stopped, even
if the compressor does not appear to be running. The compressor may have
stopped in Standby mode and may restart at any time. Do not remove covers
or attempt any service without first ensuring the compressor is isolated from
the mains power supply and is suitably tagged.
6.10 Simple Sequencing
The electronic controller is equipped with a function that will enable pressure
control regulation and sequence management of one or two other
compressors that have controllers equipped with the same facility. This
feature can be used to create an air compressor system, of up to three
compressors, operating coherently to a single pressure target with automated
timed sequence rotation. In this configuration the air compressor designated
as compressor ‘1’ becomes the system master. System pressure is detected
by the master’s delivery pressure transducer and pressure regulation is
determined by the master’s pressure set points. The master also determines
sequence rotation. Air compressors designated as ‘2’ or ‘3’ (slaves) will
respond to load / unload commands from the master.
For configuration of the sequencing function, please refer to the “Electronic
Controller Advanced Configuration” manual available from Champion
Compressors Customer Care Division.
