III.2 TESTS
III.2.1 SHORT-CIRCUIT TESTS
DO NOT
carry out this test if there is any doubt about the operation of the CCR, or if there is a fault or
breakdown.
1.
Switch off the CCR from the power.
2.
Completely disconnect the lighting loop. (or use the
“security" position of the Cut-out plate,
without
disconnection
)
3.
Short circuit terminals “HV1” and “HV2” on the load plate, (or use the “security" position of the Cut-out
plate, as above)
4.
Connect the CCR to the power.
5.
Put the CCR in “Local” mode.
The CCR starts up and the output current is displayed on the front panel.
6.
Progressively increase the brightness levels using the selection buttons while systematically checking
the current value shown by the numeric display, maximum brightness being fixed at 6.6A.
7.
Decrease the brightness levels again then stop the CCR.
8.
Disconnect from the power, connect the Lighting loop (or replace the jumpers of the Cut-out option).
If there is any problem (e.g. tripping out, Overcurrent), do not repeat the tests: check the connections
again (ground, circuit board terminals, etc) and check the state of the power modules indicators and
messages on the display.
III.2.2 OVERLOAD TESTS
The overload test is not applicable on DIAM4200 CCR because of the lack of a load adaptation plate.
III.2.3 OPEN-CIRCUIT TEST
Physically disconnect the loop (or remove jumpers of the Cut-out option) and start the CCR: the device
should stop after about 0.3s (running time) with the fault indication.
