Associating an Outputs board with sensor #1:
Note 2:
Update the number of installed Outputs boards in SLC-220 Settings (chapter 4.5).
Note 3:
In principle it is not important to associate a certain Outputs board in the chain to a certain
sensor in a rigid order.
Note 4:
It is also possible to associate more than one Outputs board to the same sensor! By
doing this, for example, two relays on different Outputs boards will give indications in parallel for
the specific sensor status, and two 4-20mA outputs will give the same information for this sensor.
Note 5:
An Outputs board associated to a disabled sensor will not operate: All relays will be de-
energized, and all 4-20mA outputs will be set to 4.33 mA.
Outputs board self-test:
1. Power down the controller.
2. Remove the jumper from JP1 / JP2 / JP3 / JP4 of the Outputs board to be tested.
3. Power up the controller.
4. The relays will be energized and de-energized in sequence one after the other.
5. The 4-20mA output will change between 5mA and 10mA when a complete sequence cycle
of the relays in finished.
6. Power off the controller.
7. Insert the jumper back to JP1 / JP2 / JP3 / JP4 (where it was before).
8. Power on. The Outputs board will operate normally.
