CONTROL SETUP - OPTIONS SETUP
“Compressor Interlock” SCREEN
This screen is shown if the “Compressor Interlock” option of
“Compressor Sequencing” was selected in Panel Setup.
For quick access to this display there is a [Compressor
Interlock Setpoints] screen key on the “Operating Status -
2” display. Compressor interlocking is used to interlock the
running of one high stage compressor with one booster
compressor. This option should be selected and set up on
the booster compressor and requires serial communica-
tion between the two compressors using the Com-1 port.
Reference drawings 640A0042 and 640A0050. These com-
pressors are sequenced only if the compressor is in the
remote start mode of operation and in remote Slide Valve
mode and available to run, i.e. not in shutdown (cutout) or
Recycle Delay.
When Compressor Interlock is activated, the program checks
the running status of the two compressors. When the
booster is started, the program checks if the high stage
machine is running. If it is not running, it is told to start. After
the high stage is confirmed to be running, the booster will
start. If the booster is running and the high stage compres-
sor has a shutdown, the booster shuts down with a “Com-
pressor Interlock Failure”. If the booster is stopped, both
machines will stop.
This display has the following setpoint:
High Stage ID - The Identification number of the high
stage compressor.
A toggle key is provided for compressor sequencing:
[Activate] - Selects the compressor control to be cur-
rently active.
[De-Activate] - Selects the compressor control to be
currently not active.
