Alarms/faults
Corrective steps
When activating the emergency switch, the lamp turns off. Switch off the unit and then
wait 15 seconds before resetting. Afterwards the power supply is ready for switching
on.
Byte "Fault" becomes 6 when answering to r command (refer to the communication
protocol). Byte "Fault" will reset when switching the power supply on.
Otherwise, but only under RS232 and manual with switching on from synoptic panel:
close the emergency contact. Then wait approx. 7 seconds (the serial communication
is disabled during this 7 second time).
The power supply has been fitted with some protection devices against overtemperature
and overpower. In case of overtemperature or overpower, alarms will be ON.
When the max. power has been exceeded:
. the lamp does not turn off
. ON/OFF byte is set to 5 when answering to L command
. J4 9-10 contacts close down
. the power supply controls the current to limit the output power
. to switch back to normal operation and clear alarms, turn off the power supply.
A sensor controls the internal temperature for a safe operation of the power supply. In
the event the temperature limits have been exceeded:
. ON/OFF byte is set to 3 during 95 seconds when answering to L command
. the lamp will be turned off after 95 seconds. After the lamp turn-off byte ON/OFF
becomes 2.
. J4 9-10 contacts close down.
. send F command to switch off/reset the unit
. allow the cooling of the unit and check the ON/OFF byte (equal to 0) through L
command
. strike the lamp.
In case the requirements for ground equipotential conditions do not comply with, some
troubles could occur when striking the lamp. For more detailed information, please
refer to the EX communication protocol section "fault control procedure (only through
RS232)".
