The Interface Solution Experts
Electrical Connections
All electrical connections are made to terminals on
the front of the unit. Each terminal is labeled.
Refer to the Installation drawings for connections.
To make a connection, loosen the screw that
corresponds to the terminal, install #6 ring or spade
lug on all wires and tighten the screw until snug or 8
inch pounds maximum.
Recommended Ground Wiring
Practices
The following ground wiring practices must be followed
to ensure proper performance of the FCT [UB]:
• Any Moore Industries product in a metal case
or housing should be grounded.
• All signals to and from Moore Industries’
products should be wired using a shielded,
twisted pair technique. Shields are to be
connected to an earth or safety ground at the
unit.
• The maximum length of any unshielded input
and/or output signal wiring is 2 inches.
Operation
Once properly calibrated, connected, and powered,
the FCT [UB] will operate reliably for an extended
period of time. Unit maintenance is a simple check
of terminal connections every six months.
If an FCT [UB] begins to malfunction or to function
below rated specifications, complete the following
checklist before calling the factory for assistance.
• Verify that all electrical connections are clean
and tight.
• Verify that the power source for the unit is
supplying power at levels rated safe and
appropriate according to product
specifications.
• Check the calibration of the instruments used
in calibrating the FCT [UB].
• Verify that other devices in the process loop
are not the cause of the problem.
If the difficulties continue, remove the unit
from service and recalibrate.
