Cascade control
Process variables for both controllers from resistance
thermometers Pt 100
In order to disable the cascade the master controller can be switched to manual mode, which
corresponds to local mode of the slave controller. The switchover back to automatic mode of the
master is hitchless. Beyond that x-tracking can be configured, so that the setpoint of the master
controller is tracked during manual mode.
The alarm circuit in the slave controller monitors the negative deviation xd.
Setting of configuring switches of the slave controller:
S1 = 4, S2 = 2, S8 = 1, S9 = 1, S10 = -1, S32 = 1
