ACS 400 User’s Manual 135
Output signal source selection
It is possible to control both the relay outputs 1 and 2, as well as the analog output from 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 the
parameters in group 32
SUPERVISION.
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 16 for more information on required parameter settings. With the given settings,
writing any value 100 - 255 to parameter 131
SER LINK DATA 1 causes the relay output 1 to activate.
Writing any value 0 - 99 to parameter 131 causes the relay output 1 to deactivate.
Refer to Table 17 for information on analog output control.
