Abstract:
A method of controlling a dispensing of an amount of lubricating liquid by a dispensing apparatus, the method comprising:disabling actuation of a valve prior to receiving an enable signal; responding to an enable signal from a control station located apart from the dispensing apparatus to enable actuation of the valve; manually actuating a valve to move from a closed position to an open position; energizing an electrically operable device for a first time to latch the valve in the open position; measuring a parameter of the flow of the liquid; and in response to the parameter equaling a preset amount, energizing the electrically operable device for a second time to unlatch the valve and allow the valve to return to a closed position and stop the flow of liquid, generating a signal to the control station, said signal representing the batch preset amount has been dispensed; and receiving from the control station a signal to return to the disabling of the valve actuator from further operation until the next enable signal is received.
