CLS204 and CLS208 Current Inputs
For each current input on a CLS204 or CLS208 controller
you must install a resistor. The value of the resistor must
be correct for the expected input range. Install the resistor
in the listed resistor pack (RP) location. Note the resistor
pack locations have three through holes. Install the resis-
tor as shown in the illustration below.
