How shall I test the Micom P139 relay watchdog contact?


-There is no dedicated output contact for watchdog signal - the user is responsible to make proper configuration by  his own.
-The configuration is as follows:
-pick-up normally close contact and configure it with [004.065] 'MAIN   Blocked/faulty'   signal and change operation mode for normally energised: Usually contact from V board. V -
-this is power supply module and it is present in all variants of Px30 ---->( please see attached file ).
-Output contacts No 8 from V board is normally closed: ----> ( see again the attached file )
-For 40TE case it would be output K908:150.214 OUTP   Fct. assignm. K 908   MAIN  Blocked/faulty      150.215 OUTP   Oper. mode K 908      NE updating         Watchdog signal should be taken from  X92-6 and X92-7 terminals ! 
-For 84TE - it would be K2008 Regarding testing - this is more local habit then general recommendation.
-We would advise to use 3 steps:
1. Device switched off  (no auxiliary voltage) - to check whether watchdog is closed
2. Device supplied with proper auxiliary voltage but blocked due to [003.030]
MAIN   Device on-line  =    No (= off) - to check whether watchdog is closed
3. Device supplied with proper auxiliary voltage and not blocked due to [003.030] MAIN   Device on-line    =   Yes (= on)    - to check
whether watchdog is openI
