A sequential circuit is built into the PC to handle power interruptions. This circuit
prevents malfunctions due to momentary power loss or voltage drops. A timing
diagram for the operation of this circuit is shown below.
The PC ignores all momentary power failures if the interruption lasts no longer
than 10 ms. If the interruption lasts between 10 and 25 ms, the interruption may
or may not be detected. If the supply voltage drops below 85% of the rated volt -
age for longer that 25 ms (less for the DC Power Supply), the PC will stop operat -
ing and the external outputs will be automatically turned OFF. Operation is re-
sumed
automatically when the voltage is restored to more than 85% of the rated
value.
6-4 Wiring
The following diagrams show the proper way to connect the power source to the
PC. The terminals marked “NC” are not connected internally.
1:1 isolation
transformer
Voltage selector
Short: 100 to 120 VAC
Open: 200 to 240 VAC
Short-circuit these termi-
nals with the shorting
bracket supplied as an
accessory to select 100
to 120 VAC supply volt-
age. For 200 to 240 VAC
leave them open.
Voltage selector
Short: 100 to 120 VAC
Open: 200 to 240 VAC
Short-circuit these terminals
with the shorting bracket
supplied as an accessory to
select 100 to 120 VAC sup-
ply voltage. For 200 to
240 VAC, leave them open.
Isolation transformer
• Noise between the PC
and ground can be sig-
nificantly reduced by
connecting a 1-to-1 iso-
lation transformer. Do
not ground the second-
ary coil of the transform-
er.
Power line
• Use AWG 14 twisted
pair cable (cross-section-
al area of 2 mm
2
min).
AC power source
• Supply 100 to
120 or 200 to 240
VAC
• Keep voltage
fluctuations within
the specified range

cables or larger . The terminal blocks have screws with 3.5-mm
diameter heads and self-raising pressure plates. For connecting to the terminal
blocks, use round crimp terminals for 3.5-mm diameter heads. Directly connect -
ing stranded wires to the terminal blocks may cause a short-circuit.
