Sensor or input signal connection

 These connections should be well done and terminals must be well tightened.

 Thermocouples must be installed with proper extension or compensation cables.

 Pt100 RTDs must be 3-wire connected and the wires connected to terminals 17

and 18 should have the same electrical resistance (same wire gauge) for proper

cable distance compensation.

 Four-wire RTDs can be connected by disconnecting the fourth wire. Two-wire

RTDs can be connected by shortening terminals 22 and 23 and connecting the

Pt100 to terminals 16 and 17.
