Step 3.
Turn printing press main power switch OFF. Using a multimeter set to ohms
scale, check for continuity of components between points listed.
Limit switch (b92): Point 47 and Point 120
Relay (d107): Point 51 and Point 52
Relay (d103): Point 33 and Point 34
if no continuity is observed, replace the faulty component (paragraphs

WARNING
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.
Check that Press Section panel breaker and main power switch are ON.
Check
that feeder panel switch (b84) is ON.
Step 2.
With FEEDER ON pushbutton pressed, using a multimeter set to ohms
range,
check for continuity at points 146 and 150 on terminal strip.
If no continuity, replace FEEDER ON pushbutton (b84) (para.
2-94).
If continuity is present, go to step 3.
