Configuring the Switching Outputs and the Continuous Output
Switching output out1 is configured with a 2-step heating controller as a standard feature (relay or transistor output, depending upon variant).
Control performance (2-step heating or cooling, 3-point discontinuous, step-action controller, continuous-action controller, split range controller) is
determined by the configuration selected for the actuating outputs. See also the “Configuration” table on page 16.
– Actuators for heating and cooling are selected independent of each other.
– If 2-step control is required, heating and cooling outputs may not be configured simultaneously for the respective controller.
– Both switching outputs can be assigned to the same controller output for separate control of several actuators with a single controller output.
– If a continuous and a discontinuous output are both configured for heating (or cooling) at the same time, the channel performs like a
continuous-action controller and the discontinuous output is inactive.
– If, inadvertently, only one “Less” output is configured for heating (or cooling), it remains inactive.
– Settings can be freely combined regardless of
controller type
.
Relay Outputs for Actuating Signals
If two relay outputs are required for the actuating signals, for example in the case of three-step or step-action control, the alarm outputs can be
exchanged with the actuator outputs.
The
Out = XCh
configuration (see page 16) exchanges the functions of
out1
with
A1
and
out2
with
A2
.
