5.5 LOAD CONNECTIONS
The XC660D is provided with 6
relay, as shown on the picture.
The relay functionality depends on
the setting of the parameters
oA1÷oA6.
According to the features of the
loads, suitable external contactors
have to be used to supply the
loads properly.
5.6 SAFETY AND CONFIGURABLE DIGITAL INPUTS

VOLTAGE
5.6.1
Loads safety inputs
Controller has 8 configurable digital inputs,
free voltage
.
Each digital input can be set by the related parameter iF01,.. iF08.
The first 6 digital inputs are factory pre-set to operate as safety input for loads.
Each input must collect the status of the safety devices related to the compressor such as
thermistors, pressure switches etc.
When this input is activated the correspondence load is switched off and not considered for the
regulation.
The correspondence between loads (compressors or fans) and safety inputs is the following
