Output signal source selection

It is possible to control both the relay outputs 1 and 2, as well as the analogue output from the serial
communication channel 1.
Relay outputs can be controlled in the following way:
Step 1: Configure the ACS 400 to supervise the value of any of the parameters 131-133 using
parameters in group 32
Step 2: Configure a relay output 1 or 2 to respond to the status of one of the supervised
parameters.
The selected relay can now be turned on or off by writing to supervised parameter (131-133) some
value that is either above or below the given supervision limits.
Refer to Table 21 for more information on required parameter settings. With the given settings,
writing any value 100 - 255 to parameter 131
Writing any value 0 - 99 to parameter 131 causes the relay output 1 to deactivate .
Refer to Table 22 for information on analogue output control.
