TB1 Terminal 7 in the slave unit If the slave unit then works properly the problem is being caused by interfering signals on the control line See control line comments below 2 No flash at all Probable cause Severe interference on the control line could prevent flashing altogether Control line requirements The control line wires must be twisted together Shielding is not necessary or recommended Shielding is not a substitute for twisting If the control line consists of two wires twisted together inside of a surrounding shield it might help to disconnect the shield at both ends A control line problem can usually be further verified by temporarily laying a substitute line twisted on the surface between the master and slave units B When only one light is affected No flash or flashing at the wrong time This is an unusual condition at initial turn on If it does happen it is most likely because a programming switch on PCB 1 was unintentionally bumped and reprogrammed while working inside the power supply during installation Correct programming information can be found in Figure 6 and also on the inside of the power supply cover for the unit affected It is also possible that the equipment was somehow damaged after leaving the factory If the flash head is located remotely from the power supply the cable could be incorrectly hooked up 22 04 02 2015 PSOV 105 106 V 12 1ff V 1 2 1ff EVOLVING PROBLEMS When a Ligh

This is primarily because the control line is the only untested part of a newly installed system Control line problems usually affect not just one but all of the lights in a system It is however possible for only one light to be affected if a programming switch was bumped while working in a power supply during electrical hookup causing it to become unintentionally reprogrammed Faults that may arise after a system has been working properly are usually due to rather predictable causes brought on by component aging deferred maintenance or perhaps some type of damage These problems usually affect only one light although there can be exceptions It is important to know where the major components are located especially when attempting to follow troubleshooting procedures Use Figures 13 and 14 for this information A slave power supply does not have a CMV 111 Control Module it is otherwise identical to a master power supply CMV 111 FLASH TUBE BRACKET ASSEMBLY Figure 14 Flash Head Internal Components Figure 13 Master Power Supply Components 19 PSOV 105 106 04 02 2015 V 1 2 1ff TROUBLESHOOTING STATUS LIGHTS Each power supply has two circuit boards with indicator lights that can be used to interpret operating conditions PCB 1 shown partially in Figure 15 is the timing and control circuit board Its location is shown in Figure 13 It has six red LEDs but only four of these apply to standard functions DS1 and DS2
