Operation - Walther WTRB-24DC-3500 Operating Manual

Rev. 1.0

5.3 Operation

The Walther Systemtechnik Temperature Controllers come with a standard configuration which will only allow
changes in the preset temperature (SP1). The parameters of the analog input were pre-configured for a PT100
2-wire resistance thermometer. Please refer to chapter 5.3.2 for the pre-settings of the limit monitoring. Table 5
in section 7.4 provides an overview of the parameters of the standard configuration.
The controller parameters of the PID controller were pre-configured for the classic use with 24 [VDC]-heating
elements of Walther Systemtechnik GmbH.
IMPORTANT
If you are not satisfied with the control performance when using a heating element with the
pre-configured control parameters, you should change/adapt the PID control parameters.
Please refer to chapter 7 "Advanced Settings" and 8.2 "Self-Optimization ".
