  • Page 6: Section 1 Overview

    RAYCHEM T2000 Series Heat Tracing Controller (HTC). A RAYCHEM T2000 HTC is made up of at least one card rack, one alarm/ communications interface card, and one or more control modules, each with its own current transformer and switching module.
  • Page 7 1.2.5 CR 2000 CARD RACK The CR 2000 card rack was the original card rack designed for use with the RAYCHEM T2000 system. It provided each control module its own isolated power supply connection. Two versions of this card rack have been manufactured. The first version did not support the ATC (Ambient Temperature Control) signal connection between the ten control modules, and the second (Rev A) version did support the ATC signal.
  • Page 8: External Programming Devices

    The type of device depends on the type of alarm/ communications interface card being used by the RAYCHEM T2000 HTC. The following sections give details on the programming devices that may be used with each type of alarm/ communications interface card.
  • Page 9: Control Module Overview

    1.4 CONTROL MODULE OVERVIEW 1.4.1 DESCRIPTION The CM 2000 and the CM 2000+ control modules, used in the RAYCHEM T2000 HTC each control, monitor, and communicate alarms and data for a single heating circuit. As single point controllers, they offer a complete range of features as well as superior reliability. The ability to install the units in Class 1, Division 2 hazardous areas supports direct field installation if desired.
  • Page 10 CSA (C/US) & FM Approved The RAYCHEM T2000 system is approved and certified for use in Class 1, Division 2, Groups A,B,C,D hazardous locations, making them ideal for direct installation in the field. This can save the expense of wiring back to a centrally located electrical distribution center.
  • Page 11: Ac 2000+ Card Overview

    CR 2000/CR 2000+ card rack(s). IMPORTANT: The AC 2000+ belongs to a family of Group Communications Controller (GCC) devices. While specific to the RAYCHEM T2000 series of products, the AC 2000+ is nonetheless a Group Communications Controller (GCC). This nomenclature will be used through this user manual.

  • Page 17: Wiring

    A ground terminal is provided on each card rack for connection of a system ground lead. Proper system grounding is required for safe and correct operation of the RAYCHEM T2000 HTC protection features. Refer to Article 501-4(b) of the National Electrical Code for grounding in hazardous areas, if appropriate.
  • Page 18: Initial Power Up

    WARNING: Before applying power to the RAYCHEM T2000 HTC: • Close the panel door or stand clear of the RAYCHEM T2000 HTC. Although the control modules incorporate overcurrent protection, a destructive switch failure can result from a short circuited output. To avoid the possibility of any injury, no one should be directly in front of the switches when they are initially powered up.
  • Page 19: Section 3 Control Module Programming And Configuration

    The control module then turns on all LEDs (except TRANSMIT and RECEIVE LEDs for the CM 2000) and sequences through a test pattern so that the operator can verify that all LEDs and display segments are functioning. nVent.com | 19...
  • Page 20 The RECEIVE status LED is located below the TRANSMIT status LED on the right side of the control module’s front panel display.
