SG-60 High Intensity Strobe System 4-1 Manual EPM-00000019 Rev A
SECTION 4. TROUBLESHOOTING
Refer to the troubleshooting flowcharts. Replace components in the order stated, and
keep track of those replaced. The following troubleshooting procedures presume that
all fuses, interlocks, and controls are functioning properly. Note that the troubleshooting
flowcharts are intended to be used as a general guide, and do not cover every possible
mode of failure.
WARNING!
1. Always turn off power when changing any component or printed
circuit board.
2. High voltage is present in the Flashhead. Do not cheat the
interlocks.
3. Do not put hands or tools in the Flashhead until the High Voltage
Indicator neon lamp DS1 on the High Voltage & Trigger board is
extinguished. Refer to Figure 1-2, Page 1-3, for the location of High
Voltage Indicator DS1 - do not confuse the High Voltage Indicator DS1,
with the PWR ON lamp DS1. Note that it is possible for the High Voltage
Indicator DS1 to be lit even when the PWR ON lamp DS1 if off. If this
happens, the energy storage capacitors C1 - C3 must be discharged
before performing maintenance.
4. Do not look directly into the Flashhead at close range when it is
flashing. Flashtubes in this lighting system produce brilliant flashes of
light containing some ultraviolet radiation, which can cause temporary
or permanent eye damage.
5. The components and assemblies in this system were designed by
Honeywell to handle the high voltages that are present. Honeywell
strongly recommends against substituting components or assemblies
that might be available through other vendors.
Before consulting the troubleshooting charts, check the following.
• The Master Controller Local/Remote Switch is in Remote (Photocell)
• If you have a Dual System, check that the Red Light Controller is also set for
Automatic Mode Control.
• Master Controller is turned on.
• Main Circuit Breakers are not tripped.
• Flashhead Fuses F1 and F2 are intact. (Remove power at breakers!)
