C7000 INSTRUCTIONS fOR A/C UNITS
The corresponding commands:
Components/Cooling
Pumps
By setting the parameter "ACTIVE" on 1 you add a pump to the configuration.
With "0" you disable the pump.
➊
In the next line you determine which type the pump shall belong to (Glycol =
Glycol-pump - all pumps for G-, GE units which are located outside the A/C
unit).
➋
With the parameter "DOUT" you determine a digital output for a glycol pump
on/off signal.
➌ In case of a proportionally controlled pump the enabling signal
is available at this output.
With the parameter "AOUT" you adjust the analog output of the proportional
signal for a glycol pump with DFC control.
➍
Alarm parameters:
Digital input

Common alarm release ➏
Alarm priority ➐
2nd menu:
For the pumps you can enable a sequencing based on time and failure. With
"partner pump"
➃ you select the number of the other pump (04).
for example:
pump 1 partpump 2
pump 2 partpump 1
Setting "0" disables the pump sequencing. Both pumps must be in the same
unit. For this the same bus address must be entered for the parameter "Partner
unit"
➂. The sequencing is based on a runtime evaluation. In case of a runtime
difference of more than 20 hours the pump with the shorter runtime is put into
operation.
