4.4 S3 PROCESS

•

STOP A: This function is used for end of travel applications. When an interlock configured for

STOP A opens the corresponding output relay will open. When the STOP A input is open the

motor cannot be started using start A commands or switch inputs.

•

STOP B: This function is used for end of travel applications. When an interlock configured for

STOP B opens the corresponding output relay will open. When the STOP B input is open the

motor cannot be started using start B commands or switch inputs.

•

REMOTE RESET: This function replaces the faceplate reset key. When configured the faceplate

reset key will not reset any trips. When other switch inputs are used to reset specific trips the

remote reset switch input will not reset those trips, i.e. Undercurrent Trip, Emergency Stop Trip,

Lockout Trips.

•

MOTOR SELECTOR A/B: This setting is used in conjunction with the Duty/Standby starter type.

In the Manual mode the state of this interlock determines which of the two motors is used for

starting (Healthy = Motor B). When A is selected only the contactor A output relay will respond to

start commands. When B is selected only the contactor B output relay will respond to start com-

mands.

•

DUTY SELECT MAN/AUTO: This setting is used in conjunction with the Duty/Standby starter

type. This input determines the mode of operation for the Duty/Standby starter type either Man-

ual or Auto. In the Auto mode the MM2 will alternatively start Motor A and Motor B. When the

number of starts is an even number Motor A will be started the next time a start command is

issued. When the number of starts is odd Motor B will be started the next time a start command is

issued. In the event of a trip on either motor, the motor that tripped will be prevented from starting

until reset is pressed. All starts will default to the untripped motor. When the trip occurs the MM2

automatically resets the trip to allow the other motor to be started. The trip message becomes an

alarm message which must be reset to allow the tripped motor to start. If the second motor trips

the MM2 will remain tripped until reset is pressed. The details of the Manual mode are described

above under MOTOR SELECTOR A/B above.

Faceplate Stop trips, Process Stop trips and ESD Stop trips MUST be manually reset

regardless of the Duty/Standby mode. Local Isolator and Plant Interlock trips reset

only when the input is healthy.
