EMERGENCY FUNCTION:
Emergency Restart
See Section 4.7.1: Digital Input Functions on page –48 for an explanation of the emergency
restart functions. In addition to the normal selections, the Emergency Restart Switch may
be used as a emergency restart input to the 369 to override protection for the motor.
When the emergency restart switch is closed all trip and alarm functions are reset.
Thermal capacity used is set to zero and all protective elements are disabled until the
switch is opened. Starts per hour are also reduced by one each time the switch is closed.

DIFF SW FUNCTION:
Differential Switch
DIFF SW TRIP RELAY:
Trip
See Section 4.7.1: Digital Input Functions on page –48 for an explanation of differential
switch functions. In addition to the normal selections, the Differential Switch may be used
as a contact input for a separate external 86 (differential trip) relay. Contact closure will
cause the 369 relay to issue a differential trip.

SPEED SW FUNCTION:
Speed Switch
SPEED SWITCH TIME
DELAY: 2.0s
SPEED SW TRIP RELAY:
Trip
See Section 4.7.1: Digital Input Functions on page –48 for an explanation of speed switch
functions. In addition to the normal selections, the Speed Switch may be used as an input
for an external speed switch. This allows the 369 to utilize a speed device for locked rotor
protection. During a motor start, if no contact closure occurs within the programmed time
delay, a trip will occur. The speed input must be opened for a speed switch trip to be reset.
