It includes indicators for alarm and output status and an integral Operator Console. An internal
connector is provided to plug in an optional communications interface.
The Control Module packaging provides a rugged, vibration-proof design.
Temperature sensor, communications, and alarm control wiring are connected to the
lever-operated spring terminals, providing gas-tight, vibration-resistant connections.
A large, easy-to-read alphanumeric display and menu-driven interface eases controller
con- figuration and eliminates the need for an external programmer. Access is available for
all monitored parameters, programmed values, and alarm information. Enhanced security is
provided by password protection.
Single phase current monitoring, ground fault detection, and voltage monitoring are provided.
The nVent RAYCHEM 910 Control Module also incorporates a universal power supply, allowing
operation directly from 100 to 277 Vac.
1.4.2 COMMUNICATIONS INTERFACE
In applications where the user wishes remote configuration capability, or wants to
communicate trace information and/or alarms to another device such as a Group
Communications Controller (780 Series/GCC-9000), an optional communications interface
may be installed in the Control Module.
A modem version that maintains compatibility with legacy products is available, or other
industry-standard interfaces such as nVent RAYCHEM RS-232 and RS-485 may be specified.
