Starter Dry Run
44 RTHC-SVD01B-EN
Note:
Time period F must be long enough to verify the absence of
phase currents caused by the closing of the “Short” contacts.
The sum of intervals M and N are designed to be 2.5 Seconds.
The transition complete contact closure is expected to be an aux-
iliary contact to the “Run Contactor” (1K2).
The level 2 Contactor Integrity Test can be defeated, and the 1K1
contactor not be momentarily energized 1 second before start.
Steps A-E only when Starter Contact Test is enabled.
