Flush timer adjustment
The flush timer duration can be increased or decreased by adjusting the flush
timer restrictor. This controls the rate of airflow out of the timer circuit reservoir,
and the speed that the pressure falls in order to actuate the automatic flush stop
valve.
To set the timer, simply adjust the restrictor and then time the flush cycle.
Continue this procedure until the desired flush time is obtained. Times of over 60
seconds are achievable with this circuit.
NOTE: If the restrictor is fully wound in, air flow will be blocked and the
timer will not operate.
MPG adjustment
The characteristics of the MPG control circuit can be modified by adjusting the
MPG restrictor. This component controls the rate at which air is supplied to the
pump speed control circuit. When the MPG, PPVS or catalyst over-pressure
devices leak air more air than can be supplied through this restrictor, the
pressure in the circuit falls and the pump stops.
When the circuit is once again sealed, the restrictor controls how quickly the
pressure builds within the circuit and therefore the time and speed in which the
pump restarts.
The slower the flow of air through the restrictor, the longer the pump will take to
restart.
NOTE: If this restrictor is fully wound-in, air flow will be blocked and the
pump will not start. Conversely, if too higher flow of air is supplied to the
circuit, safe and correct operation of the machine cannot be guaranteed.
The response of the pump can further be slowed if required, by the addition of an
air reservoir to the circuit. Contact MVP for further information.
