Flashhead Isolation Test

Disconnect the seven conductor cable from power supply at terminal block TB2. Using an Ohmmeter, check the resistance between the conductors of the disconnected flashhead cable, and compare to the expected values:

FG 2000B White Strobe (cable disconnected from power supply)

#1 Red: Open to all conductors

#2 Brown: Open to all conductors

#3 Black: < 5Ω to blue, open to all others

#4 Blue: < 5Ω to black, open to all others

#5 White: < 5Ω to gray, open to all others

#6 Gray: < 5Ω to white, open to all others

#7 Ground: Open to all conductors

Flashhead Test Results

1.Correct readings do not ensure that the flashhead and cable are good, but this is a quick check for obvious problems.

2.If the readings above are correct, proceed to the Power Supply Isolation Test.

3.If #5 (gray) to #6 (white) is greater than 5Ω, or is ‘open’, suspect that the flashhead interlock switch is not depressed.

4.For other inconsistencies with the above chart, the probable causes are miswiring, or conductors shorted and/or opened. If possible, disconnect the flashhead cable at both ends and perform a ‘Megger’ test with a Megohm Meter.
