8.14 Bypass Contactor
Notes:
• End of Ramp relay is energized after a programmed time delay EOR Relay Delay Refer to section 4.7.3 page
29 for programming.
• The End of Ramp relay is de-energized when:
o
SOFT STOP or STOP signals are initiated
o
Energy Save signal is initiated
o
Slow Speed/ Slow Speed Reverse signal is initiated
o
Fault condition occurs
• ASTAT-XT current protection is operative after the bypass contactor closes only when the bypass contactor is
wired to terminals A, B and C as shown in the drawing above.
• When a SOFT STOP signal is provided, the End of Ramp relay returns to its original position opening the bypass
contactor. Thereafter, the voltage will gradually ramp down to zero, soft stopping the motor.
