Docking Station relay test
The Docking Station relay test function allows the SSR, SFR, pre-alarm and main
alarm relay on the Docking Station to be tested.
The SSR is a positively-driven relay that is not energised when not operating
(energized on alarm).
The pre-alarm and main alarm relays are relays that are not energised when not
operating (energized on alarm).
The SFR has a redundant design for safety. Two relays are used as normally closed
or normally open relays depending on the application. There are a total of 3 relays
on the Docking Station for both modes of operation: 1x NO, 1x NC, 1x COMMON
(NC/NO).
The corresponding 2 relays must be tested separately depending on the selected
mode of operation:
– In the Normally Open mode of operation, the closing of the contacts must be
measured at the applicable contacts of the Docking Station when the applicable
NO relay is actuated.
– In the Normally Closed mode of operation the opening of the contacts must be
measured at the applicable contacts of the Docking Station when the applicable
NC relay is actuated.
Requirements:
– A consumer is connected to the SFR, SSR, pre-alarm and main alarm relay.
– If no consumer is connected, a continuity tester must be used to check the
flawless function of the relay.
