4.2 Electrical

Electrical connections to the transmitter are made to the screw terminal provided on the top face. The correct type of thermocouple wire must be used to connect sensor, this will normally be provided as part of the probe assembly. The screw terminals allow for wires to enter either inner or outer direction. Never attempt to unscrew the spare terminal which secures the factory

tted cold junction sensor. The terminal is adjustment. The transmitter is protected against re connection is made the transmitter will go into either up or down scale output current, depending on con Figure 2 gives connection details, the output is shown connected to a 24V supply.

panel indicators and loop isolators. The load value can range from 0 ohms to the max loop load for given supply, refer to section 3 “Max load” for more information. The transmitter conforms with EC di termina Shielded or twisted pair wires are recommended for output wires. Always ensure the mA loop is grounded at one point, this would normally be at the monitoring equipment or loop power supply. In normal operation the range “R” LED acts as over-range LED.
