25-80 Pack Status
Option: Function:
Read out of the status of the Pack Controller.
Disabled Pack Controller is disabled (
Pack Controller
, Par. 25-00).
Emergency All compressors have been stopped by means of a Coast/Coast inverse or an External Interlock
command applied to the frequency converter.
Off All compressors have been stopped by means of a Stop command applied to the frequency con-
verter.
In Open Loop
Configuration Mode
, Par. 1-00, has been set for Open Loop. All fixed speed compressors are stop-
ped. The variable speed compressor will continue to run.
Frozen Staging/destaging of compressors has been locked and reference locked.
Jogging All fixed speed compressors are stopped. When stopped, the variable speed compressor will run at
jog speed.
Running A Start command is applied to the frequency converter and the Pack controller is controlling the
compressors.
Running FSBW The frequency converter is tripped off and the Pack Controller is controlling the fixed speed com-
pressors based on
Fixed Speed Bandwidth
, par. 25-22.
Staging The Pack Controller is staging fixed speed compressors.
Destaging The Pack Controller is destaging fixed speed compressors.
Lead Not Set No compressor available to be assigned as variable speed compressor.
25-81 Compressor Status
Option: Function:
Compressor Status shows the status for the number of compressors selected in
Number of Com-
pressors
, par. 25-01. It is a readout of the status for each of the compressors showing a string,
which consists of compressor number and the current status of the compressor.
Example: Readout is with the abbreviation like “1:D 2:O” This means that compressor 1 is running
and speed controlled by the frequency converter and compressor 2 is stopped.
[X] Disabled The compressor is interlocked either via
Compressor Interlock
, par. 25-19, or signal on a digital
input programmed for Compressor (number on compressor) Interlock in
Digital Inputs
, par. 5-1*.
Can only refer to fixed speed compressors.
[O] Off Stopped by the cascade controller (but not interlocked).
[D] Running on Frequency Converter Variable speed compressor, regardless if connected directly or controlled via relay in the frequency
converter.
[R] Running on Mains Running on mains. Fixed speed compressor running.
25-82 Lead Compressor
Option: Function:
0 N/A Readout parameter for the actual variable speed compressor in the system. The Lead Compressor
parameter is updated to reflect the current variable speed compressor in the system when an al-
ternation takes place. If no lead compressor is selected (Cascade Controller disabled or all com-
pressors interlocked) the display will show NONE.
25-83 Relay Status
Array [2]
On
Off Read out of the status for each of the relays assigned to control the compressors. Every element in
the array represents a relay. If a relay is activated, the corresponding element is set to “On”. If a
relay is deactivated, the corresponding element is set to “Off”.
