SYNCHRONISM CHECK UNIT:
89 OPEN, Compare V1 with V2:
• Remove auxiliary voltage from terminal PI1 (89 open).
• Apply 60 Vac at 60 Hz to V1 and V2 with an angle difference of 0º between both voltages.
• Change the following settings and check that contacts SP1, SP2, SP3 and SP4 close.
• Increase voltage V1 and check that for 70 Vac, contacts SP1, SP2, SP3 and SP4 open.
• Decrease V1 voltage to 60 Vac.
• Change V1 angle with respect to V2, and check that when reaching 10º , contacts SP1, SP2, SP3 and SP4
open.
89 CLOSED, Compare V1 with V4:
• Apply auxiliary voltage only to PI1 (89 closed).
• Apply 60 Vac at 60 Hz to V1, V2 and V4 with an angle difference of 0º between V1-V4 and V2-V4, and check
that contacts SP1, SP2, SP3 and SP4 close.
• Increase V4 and check that when reaching 70 Vac, contacts SP1, SP2, SP3 and SP4 open.
• Decrease V4 to 60 Vac.
• Change V4 angle with respect to V1 and V2, and check that when reaching 10º, contacts SP1, SP2, SP3 and
SP4 open.
