Operation
Check functioning of the closing solenoid Y9 and all available shunt
releases by operating them electrically.
If there is a 3AX1103 undervoltage release (Y7): Has the locking screw of
the striker been shifted from position A to B (see "Removing the transport
block from the undervoltage release" on page 48)?
If there are interlocks and a retrofitted key-operated interlock: Check if the
function of the interlocks as per IEC 62271-200 is guaranteed.
