Control circuit for Motor Operators
The motor operator incorporates a self-hold circuit for the closing and opening signals. Therefore a momentary (over 50msec.) open or close signal will ensure
a complete operation. When the breaker trips, the breaker is reset by applying a signal to the OFF terminals of the motor.
When an undervoltage release UV is used with a motor operator, design the control circuit so that the undervoltage release UV is energised before a reset
or close signal is sent to the motor operator. A 40ms time delay in the reset and close signals is sufficient to allow the undervoltage release UV to energise.
When a shunt trip release is used with a motor operator, design the control circuit so that the shunt trip release is de-energised before a reset or close signal
is sent to the motor operator.
When a mechanical interlock is used with motor operators, design the control circuit to provide electrical interlocking between the motor operators. The
electrical interlocking should prevent a close signal being sent to a motor operator unless the other motor operator and circuit breaker are in the OFF position.
