Note:
The firing test is limited to 60 seconds (30 seconds in older than 27.12.2010 software versions). If you did not
manage to conclude the test you can repeat until all 5 stages are done.
If the firing test fails:
Check the fuses in the switch mode power supplies (PC2075 for AC control voltage, PC2076 for DC control
voltage). Refer to section
10.2.4 page 93 for fuse locations.
Note:
DC control voltage uses all three fuses in a series, so if one fails to operate, all firing LEDs can’t light.
Check that fiber optic wires # 1, 3 and 5 (firing phases 1, 2 and 3) are properly connected according to the
markings on the Control Module.
Check that they are inserted into their connectors to the full depth and not damaged .
Check that the fiber optic wires of the power modules that are connected between the individual power
supplies (PC2075 or PC2076) and the firing PCBs are properly inserted.
When Control Voltage is turned ON, the green LEDs in the power modules may blink shortly. This is normal.
