The heatsink temperature of the power part of
some DCS converters is monitored via a PTC element. Other DCS converters check the cooling air
temperature and the airflow. The third option is this
one, which measures the fan current being within
limits. In case the fan current is too low or there is
no fan current at all or it is too high, the drive needs
to be switched off. The fan current may be too low
because
- the fan may not be switched on or
Data

AC input / output current: 5 A
AC peak current: according to fan starting current; external switching device needed
AC isolation voltage: 690 V (supply via autotransformer)
Load: single phase AC motors with starting capacitor

5.9.1 PW 1002
This device is designed and used exclusively at
DCP converters above 800 A directly in default
condition. It is supplied by a 230 V single phase
power supply and will monitor the two single phase
fans mounted on top of the converter in parallel
configuration. The transfer characteristic is identical
to the one described at the PW 1003. The part
power section cooling within this manual shows the
interconnections between the power supply, the
fans and the interface board PG 7xx3.
- any protection device within the fan supply has
acted or
- a wire is broken or
- the propeller became loose or something similar
The fan current may be too high because
- the fan may be blocked mechanically or
- there is a short circuit in the fan winding or something similar
The overcurrent during acceleration can be suppressed by the software.This device is designed to be used together with
the DCR kit at any type of rebuild application. It can
monitor the current of single or three phase fans
and it can be cascaded, which means multiple devices can be connected to one PTC input to monitor several fan current. The transfer characteristic
shown at figure 5.9/3 needs to be adapted to the
fan current either by changing the burden resistors
or by a software parameter, depending on the type
of fan already used for the existing power part.
