The fields and their contents are as follows:
(0 to 9)
(List box:) The means by which proof of compressor
operation is monitored.
None: No proof
OI: A digital input (on-off input) is used for proof.
CT: A current transformer is used for proof.
Bitzer: Proof is obtained from a Bitzer electronic
module.
(List box: Yes, No) Whether or not Bitzer compres-
sors are reset by a digital output (relay output).
(1 to 500) The capacity of the compressor.
(0 to 4) The number of compressor unloader stages.
(1 field per unloader: 0-99) The percent of capacity
shed by the respective unloader.
(List box:) Type of variable speed control.
None: No inverter control
VO: An inverter is controlled by an analog output
(variable output).
VLT: A Danfoss VLT adjustable frequency drive is
used.
(1.0 to 150.0) The minimum percentage of rated
speed at which the inverter will run the compressor.
(1.0 to 150.0) The maximum percentage of rated
speed at which the inverter will run the compressor.
(1 to 9999) The RPM that will be displayed at maxi-
mum percentage.
(0 to 10) The number of resets after which the
inverter will be put in override.
(0-99) The number of seconds without proof that must
elapse before an inverter reset occurs.
before second and subsequent inverter resets.
