Checking the voltage at the PCB and the transfor-
mer:
8. Using a voltmeter, measure the voltage at the con-
tacts
A
:
• The additional LED displays
D
/
E
mean:
-
Green LED display
D
is lit up = undervoltage
-
Red LED display
E
is lit up = overvoltage
• The voltage must be 24 V +/-0.5 V.
-
In the case of voltage deviations, reset the volt-
age on the transformer in accordance with the
specified values in the table.
• If there is no voltage to measure:
-
Test the cables according to Section 10.
• If the voltage is correct, change the PCB:
-
remove all cable connectors from the PCB,
-
unscrew the two Allen screws
F
and remove the
PCB,
-
fit the PCB as described above, but in reverse or-
der and attach the cable connectors.
Installing the lamp cover:
9. Insert the sheet-metal clips

as described above,
but in reverse order.
