INSTALLATION (CONTINUED):
Signal Cable:
The Signal Cable consists of the following:
Core sensors; two each (one primary, one backup), same type.
Thermal cutoff (TCO) device
Customer specified DB9 plug connector/housing
1) Connect Signal connector to the mating receptacle (customer supplied). Refer to electrical
schematic 62-0072 for details.
Heater Core Sensors:
The SHC inline heater is supplied with redundant core temperature sensors. These sensors
must be installed into a customer-supplied control package to protect the equipment from
accidental damage and to ensure operator safety. Refer to the facilities and electrical prints for
the specific temperature sensors supplied with the heater.
NOTE: Failure to use the supplied sensors for their intended purposes may void all
or part of the equipment warranty. Consult factory for technical assistance.
Heater Element TCO (Thermal Cutoff):
The Heater Element TCO is a bimetallic switch that opens when it reaches a preset
temperature. This is a resettable device which must be connected to interrupt the operation of
the control circuit if it is activated by an element over-temperature condition.
Do not connect the TCO in series with the heating
element/main load. The TCO is designed to be wired
into the heater’s safety control circuit.
Protection of the circuit shall be done with a fuse,
according to IEC or EN 60691 or a circuit breaker
according to IEC 60947-2.
