HIGH VOLTAGE
Do not operate printing press until you are sure TSS Press Section is
connected to a suitable ground. Failure to do so may result in death or
serious injury.
Shut off power source before attempting to disconnect, service, or con-
nect wires or cables. Failure to do so may result in death or serious injury.
When working on high-voltage components, always have an additional
person present, and keep one hand away from equipment to reduce hazard
of current flowing through vital organs of body. Remove all jewelry from
fingers, wrists, and neck prior to working on electrical components.
Failure to do so may result in death or serious burns.
Step 1.
Step 2.
Step 3.
Assure that Press Section panel circuit breakers are ON. Using a multimeter set
to range higher than 220V ac, check for 220V ac at output side of press section
load center circuit breakers.
If no power is present, refer to press section electrical troubleshooting
in TM 5-3610-287-24.
If power is present proceed to step 2.
Using a multimeter set to range higher than 220V ac, check for 220V ac at input
terminals to main power switch.
If power is present, proceed to step 3.
If no power is present, check wiring to press and replace as required.
Using a multimeter set to a range higher than 220V ac, check for 220V ac at main
power switch output terminals.
If power is present, proceed to step 4.
If no power is present, replace main power switch (para. 2-93).
