HOW TO WIRE
THE PC100
The rear panel of the PC100 controller contains 36 screw
terminals for connecting #28 to #18 gauge insulated wire
(#18 gauge stranded twisted pair shielded cable is recom-
mended.)
A wire stripper and a small screwdriver are the only tools
required. Detailed diagrams in this section illustrate the
proper wiring procedures for all standard and optional
functions.
At installation, be sure to comply with the following
requirements:
• Disconnect power to the unit before attempting any
connection or service to the unit
• Avoid using machine power service for AC power. When
possible, a dedicated or lighting circuit is recommended
• Do not bundle or route signal lines with power lines
• Keep all lines as short as possible
• Use twisted pair shielded wire for all input wiring
• Observe all applicable local electrical codes

HOW TO UNPACK, ASSEMBLE
AND INSTALL THE PC100

Note: K1 relay coil jumper is factory wired to terminal 8.
K2 relay coil jumper is factory wired to terminal 9. At the
end of the batch, transistor outputs 2 and 2A (terminals 6
and 9) are energized. At prewarn, terminal outputs 1 and 1A
(terminals 5 and 8) are energized.
Note: If damage to the shipping container is obvious,
request that the carrier be present when the product is
unpacked. All claims for equipment damage during transit
are the sole responsibility of the recepient.
UNPACKING
After carefully unpacking the unit, check
for any visible sign of damage. If found,
notify the carrier for insurance purposes
and call the factory for possible replacement. Keep all
packing material in the event that the unit must be return
to the factory.
ASSEMBLY
The PC100 can be installed on the flow-
meter, on a wall or shelf, or in an instru-
mentation panel. The picture below shows
the exploded view of a meter or wall
mounted unit. In this configuration, the
PC100 is shipped separately and must be installed as shown.
(See wiring diagrams for proper transmitter signal connec-
tions.)
The basic unit is equipped for panel mount. To install:
1- Measure and cut mounting hole to the dimensions shown.
2- Install gasket around the mounting bezel.
3- Pass the unit through the front panel cutout.
4- Secure the unit to the panel with the mounting clips.
5- Complete wiring and reassemble unit.
Note: Operating tempera-
ture is 32° F to 130° F (0°
to 55° C) with a maximum
humidity of 85% non-con-
densing.
Always select a mount-
ing location with proper
ventilation and environ-
ment protection.
