Installation

Inputs

This section covers input scaling and input installation for all input
types, including thermocouples, RTDs, current inputs, and voltage
inputs.

Input Scaling

The CLS analog input circuitry accepts any mix of thermocouples, 2 or
3 wire RTD inputs, current inputs, and voltage inputs. You can directly
connect the following inputs:

J, K, T, S, R, B, and E thermocouples.

Linear inputs with ranges between -10 and 60 mV.

Other inputs require custom scaling resistors. If you didn't order your
unit with the appropriate resistors, you have the following options:

Watlow Anafaze can install scaling resistors on your unit for a nomi-

nal fee.

Watlow Anafaze can supply a scaling resistor kit that a qualified

technician can use to install scaling resistors.

WARNING

A qualified technician can install scaling resistors in the
CLS. However, damage to the CLS due to improper resis-
tor installation is not covered under warranty, and repairs
can be expensive. If you have any doubts about your ability
to install scaling resistors, send your CLS to Watlow
Anafaze for resistor installation.
