ABSTRACT:
An apparatus and method for controlling the operation of a solenoid includes a control circuit configured to receive an activation signal in response to a predetermined condition. The control circuit, in response to said activation signal, provides a first energizing signal to the solenoid for a first predetermined period, and cuts off the first energizing signal for a second predetermined period. The control circuit further provides a second energizing signal to the solenoid for a third predetermined period.
