Operation and Field Wiring Information
This chapter is divided into two sections:
Section 1: Principles of Operation for the Temperature Controller
Section 2: Field Wiring Information
Section 1: Principles of Operation
Temperature Control
PID Control Parameters
Each zone receives a set of PID parameters from the Series 90-30 CPU for closed-loop control.
Individual parameter action (proportional, integral, derivative) for each zone can be disabled by
setting the parameter to 0.
Operating Temperature Setpoint
Temperature Tolerance Bands
For each zone, an operating temperature setpoint from 0°C to 450°C for J and L thermocouples,
or from 0°C to 600°C for K thermocouples can be set. The temperature is given in 0.1°C
increments.
For each zone, two temperature tolerance bands, labeled deviation and alarm, can be preset above
and below the temperature setpoint. Each zone temperature regulator operates within these
bands. The band temperature range extends from 0°C to 450°C (600 °C), given in 0.1°C
increments. With these two tolerance bands the following conditions can be checked:
