Barrel Temperature Control Module

Publication 1746-IN020B-EN-P - July 2002

Make certain the color of the RTB mathces the color band on the module.

View the write–on label to identify the slot, chassis and module type.

Align the RTB retaining screws with the mating connector on the module. Be careful
not to damage the CJC sensors.

Press the RTB firmly onto the connector contacts.

Alternately tighten the two retaining screws to avoid cracking the RTB. Tighten to a
maximum 6-8 inch-pounds.

ATTENTION

Inserting a wired RTB on an incorrect module can damage the module’s
circuitry when power is restored.
