COIL 2:
•
Repeat the previous test for coil 2. Positive should be applied to terminal F7 and negative to terminal E8.
The signal to be checked is "Coil 2 DC Supply Failure".
6.30. MONITORING TRIP CIRCUITS : COIL FAILURE
(Only for models with expansion board)
COIL 1:
• Short-circuit terminals E5, F6 and E6 (common).
• Apply nominal minimum voltage (38 Vdc for "A" models and 88 Vdc for "H" models) to the voltage
supervision input for coil 1. Positive is applied to terminal F5 and the negative to terminal E6.
• Check using GE_LOCAL software that the "Coil 1 Continuity Failure" signal in the internal Status of the
relay is not active.
• Remove the short-circuit between terminals E5 and E6.
• The "Coil 1 Continuity Failure" signal will not become active.
• Remove the short-circuit between terminals F6 and E6.
• After 1 sec, the "Coil 1 Continuity Failure" signal will become active.
COIL 2:
• Repeat the previous test for coil 2. Positive is applied to terminal F7 and negative to terminal E8. The
terminals corresponding to terminals E5, F6 and E6 will be E7, F8 and E8 respectively. The signal to be
checked is "Coil 2 Continuity Failure"
