Alarm/fault displaying
Corrective steps
When activating the emergency switch, the lamp turns off. The synoptic panel will
display "emergency - switch off mains". Switch off the unit and then wait 15 seconds
for resetting. Afterwards the power supply is ready for switching on.
Otherwise, but only under RS232 and manual with switching on from synoptic panel
modes: close the emergency contact. Then wait approx. 7 seconds (the serial commu-
nication is disabled during this 7 second time).
The power supply has been fitted with some protection devices against overtemperature
and overload. In case of overtemperature or overload, alarms will be ON.
When the max. power has been exceeded:
. the lamp does not turn off
. the display lower line will display: e 1
. the alarm LED comes on and J4 9-10 contact closes down
. the power supply controls the current to limit the output power
. turn off the power supply to reset.
A sensor controls the internal temperature for a safe operation of the power supply. In
the event the temperature limits have been exceeded:
. the display lower line will display: e 2
. the lamp will be turned off after 90 seconds
. the alarm LED stays on and J4 9-10 contact closes down.
. press OK to reset (the display is cleared, the alarm LED comes off, the remote
contact opens)
. press OK once again to strike the lamp.
When the power supply is ON it is possible to remove/disconnect the synoptic panel
only under Ext_10V and RS232 modes. If removed under manual mode, the power
supply will turn off after 6 seconds. Consequently no information will be displayed/
available on the power supply status.
The insertion of the synoptic panel is not possible when the power supply is on: in this
case the lamp could turn off and the data referred to the hour meters could be lost.
To correctly insert the synoptic panel: turn off the power supply, wait 15 seconds and
then insert it. Then, turn on the power supply again.
