3.19.1 25-** Pack Controller
Parameters for configuring the Basic Pack Controller for sequence control of multiple compressors. For a more application oriented description and wiring
examples, see section
Application Examples, Basic Pack Controller
.
To configure the Pack Controller to the actual system and the desired control strategy, it is recommended to follow the below sequence, starting with
System Settings
, par. 25-0*, and next
Alternation Settings
, par. 25-5*. These parameters can normally be set in advance.
Parameters in
Zone Settings
, 25-2*,
Staging Functions
, 25-3* and
Staging settings
, 25-4*, will often be dependent on the dynamic of the system and
final adjustment to be done at the commissioning of the plant.
In most cases, only 25-0* and 25-2* will need adjustment.
NB!
The Pack Controller is supposed to operate in closed loop controlled by the built-in PI controller (Closed Loop selected in
Configuration
Mode
, par.1-00). If
Open Loop
is selected in
Closed Loop
, par.1-00, all fixed speed compressors will be destaged, but the variable
speed compressor will still be controlled by the frequency converter, now as an open loop configuration:
