OPERATION
5.1
GENERAL
The bulk of the operation is associated to the monitoring unit. This is described in the
Manual
for monitoring unit PCM2
. Other operation is detailed in this section.
5.2
RECTIFIER MODULES
5.2.1
General
The front panel of the rectifier module has push-buttons for
manoeuvring of the module together with a number of led indication
lamps.
5.2.2
Manoeuvre
5.2.2.1
ON
To start the rectifier module, push the ON-button. A green led lamp on the upper left corner of
the button tells that the module has started and the orange led lamp by
the STBY-button will be put out. DC OK will be put out while ALARM
will go red.
If both the ON- and STBY-indications are put out but ALARM is red, the
overvoltage protection HVSD may have tripped the module. In this state, it is possible to try a
restart by keeping the ON-button pushed for about 5 seconds. Alternatively, you can put the
module in standby mode by keeping the STBY-button pressed for at least 5 seconds.
5.2.2.2
STBY (standby)
To stop the rectifier module, push the STBY-button as long as the orange led lamp on the upper
left corner of the button is flashing (about 3 seconds). In this way,
unintentional shutting off is avoided. When the module is in standby
state, the orange STBY-led is put on with steady light while the green
ON-led is put out.
If the ON-led is slowly flashing while the STBY-led is off, the output
voltage is set to zero as in standby state. The reason might be that the module has remotely been
turned off via the function “External blocking” or it may be due to high temperature. Also in
this state, it is possible to use the STBY-button to turn off the module “for real”.
WARNING:
Note that the standby state does not make the equipment dead. For a total dead state, the
mains supply and the equipment's DC output must be cut externally. For isolation of individual rectifier
modules, the built-in miniature circuit breakers are used.
