9900-1BC Batch Controller Manual
Wiring Tips:
• Do not route the sensor or DC power cables in conduit containing AC power
wiring. Electrical noise may interfere with sensor signal.
• Routing the sensor cable in grounded metal conduit can help prevent
electrical noise and mechanical damage.
• Seal the cable entry points to prevent moisture damage.
• Only one wire should be inserted into a terminal.
• Splice double wires outside the terminal or use appropriate wire ferrule,
not to exceed 2 mm (0.08 in) diameter.
Tools Required
• Phillips screwdriver
• Flat-head screwdriver
• Wire strippers
System Start-up: Step 2
Wire the transmitter connections with the power off. Keep any 4 to 20
mA and relay-actuated output devices that are connected to it offl ine at
this time. Wire the sensor (pg. 8), power (pg. 9) and Open Collector and
relay(s) (pg. 10).
Next step: System Setup (Step 3).
All wiring connections to the 9900-1BC are made via removable terminal plugs.
In general:
• Terminals accept 12 to 24 AWG wire.
• Strip 7 mm (0.28 in.) of insulation from wire tips and tin bare ends to
eliminate fraying.
• Insert wire tip or ferrule completely into the terminal and secure with
the screw.
• Do not allow any AC leads that may be connected to the internal relays to
come in contact with low voltage wiring.
CAUTION:
DO NOT bundle Relay Module
wiring with other wiring.
Doing so may cause damage to 9900 Transmitter,
Relay Module, and Batch Module.
Wiring
•
Minimize handling of plug-in modules to reduce the possibility of
damage due to ESD.
•
Handle modules by the edges. Never touch any exposed circuitry or
contacts.
•
Wear an anti-static wristband or stand on an anti-static mat, or
keep one hand touching a properly grounded pipe or other properly
grounded piece of metal when handling modules.
CAUTION:
Avoid Electrostatic Discharge (ESD)
