Honeywell MICRONIK 200 R7426A,B,C TEMPERATURE CONTROLLER User Manual

This document provides instructions and procedures for installing and starting up the Micronik 200 R7426A,B,C controllers. No special tools are required for mounting and installation. The user interface and liquid-crystal display allow accurate and easy parameter setting and output adjustment.

BEFORE Honeywell MICRONIK 200 INSTALLATION NOTE

  • Visually inspect equipment for shipping damage. Report any damage to the appropriate Honeywell representative.
  • Refer to job drawings for specific installation information and mounting location.
  • Verify the controllers will be adequately separated from the main power supply, relays, or other equipment which can possibly generate electromagnetic interference.
  • Verify that the ambient temperature and the humidity at the controllers will not exceed 0...50°C (32...122°F) and 5 to 95% rh.
  • Use shielded wiring in areas with high EMI.
  • All wiring should be separated from power lines by at least 150 mm (6’’).
  • Do not install controllers near frequency converters or other high-frequency sources.

Honeywell MICRONIK 200 MOUNTING

The controllers can be mounted in an electric cabinet or other suitable enclosure. They are suitable for back panel, DIN rail, wall, or front panel mounting. The corresponding mounting sequence, as well as dimensions and panel cut-out, are illustrated in the mounting instruction sheet EN1B-0202GE51 supplied with the controllers. If the compensation sensor signal (T3) is received from another controller (parallel connection of compensation sensor inputs), the jumper W303 has to be cut before mounting the controller (see Fig. 2). This disconnects the sensor from the internal power supply.

Honeywell MICRONIK 200 WIRING

Screwless type, spring loaded terminals are provided on the controllers for panel and field wiring. These terminals are suitable for solid conductors as well as tinned or with multicore cable end, stranded wires up to 1.5 mm2. To make a termination, push the wire into the terminal or insert a small screwdriver from the front of the controller into the spring-release hole and insert the wire. Check for proper connection by short pull on the wire.
