: Contains specialized patented hardware for synchronous application on EEPROM
that cannot be viewed/accessed.
The following list of components are devices which the SyncPro is
connected to, or are part of the SyncPro protection package.
Motor Contactor (M)
The motor contactor is used to provide and switch the power
supplied to the motor stator. It is controlled by the SyncPro
package and is necessary to remove stator power in the event of a
stop command or a trip condition. Two normally open contactor
auxiliaries may be required; one mandatory N.O. contact to give
contactor status information to the SyncPro, and one may be
needed as a hold-in contact for the main control circuit.
Motor Contactor Pilot Relay (CR1 or MR)
This interposing relay allows the SyncPro output to pick up the
main contactor coil. The power requirements of the pick-up coils
used in most medium voltage motor starters would exceed the
switching capability of the 1746-OX8 output contact.
