NB!
Danfoss recommends using 24 VDC as thermistor supply voltage.
1-91 Motor External Fan
Option:
Function:
[0] *
No
No external fan is required, i.e. the motor is derated at low speed.
[1]
Yes
Applies an external motor fan (external ventilation), so no derating of the motor is required at low
speed. The graph below is followed if the motor current is lower than nominal motor current (see
par.1-24
). If the motor current exceeds nominal current, the operation time still de-
creases as if no fan were installed.
1-93 Thermistor Source
Option:
Function:
Select the input to which the thermistor (PTC sensor) should be connected. An analog input option
[1] or [2] cannot be selected if the analog input is already in use as a reference source (selected in
par.3-15
When using MCB112, choice [0]
None
must always be selected.
