connected (x = 1, 2, ...6). The limit values can be programmed by the user for each
channel.
In the factory setting, the measurement channels are divided into two groups of
three channels. With motors, for example, three PT100 can, therefore, be
monitored in the stator windings and two PT100 in the motor bearings. Channels
that are not used can be masked out using appropriate parameter settings.
The output relays are integrated in the internal fault and warning train of the
cabinet unit. The messages can also be picked up by the customer via two spare
fault signaling relays. Two user-programmable analog outputs are also available
(0/4 to 20 mA and 0/2 to 10 V) for integration in a higher-level controller.
