7.8.6 Testing the outputs
You can use manual mode to test the correct connection of an actor.
Take the alarm chain into account before conducting the test and inform
any connection points or interrupt the alarm chain for the period of the
test.
Test the connected actors
Pre-conditions for actions:
ü
The actors have been connected in accordance with section 7.8
„Connecting the actors“ on page 24.
ü The device housing cover is closed.
ü The voltage supply has been established and the device has been
switched on.
Perform the following work steps:
1.
Working in the main menu, navigate to “Manual mode” (see section
9.4 „Manual mode“ on page 37).
4
You will now see all the outputs.
2.
Select the output to which you have connected the actor and which
you wish to test.
3.
Enter a value between 0 and 100 % and check whether the actor re-
acts as desired.
