reference to fig2 which is a flow diagram of the operation of the circuit of fig1 in step 100 pressure switch 100 is set to the saturation pressure by conventional electrical or mechanical adjustment in step 110 the circuit is set to the proper intermittent cycle time this is accomplished via vr1 and vr2 both of which are variable resistors which allow adjustment of the frequency of clock circuit 120 the delay time of timing ic 117 can be varied by adjusting the values of capacitors c6 and c4 in step 120 the machinery to be lubricated is started and vcc power is simultaneously applied to the timing circuit in block 130 vcc will be applied to timing ic 115 and the intermittent timing sequence begins in block 140 relay 210 is activated and power is applied to the pump motor pumping of oil begins and the injection pressure builds at the pressure sensing switch 100 as shown in step 150 as the pump motor begins to operate timing ic 115 continues the intermittent timing function and begins the watchdog timing function the oil pump output function is monitored at pressure switch 100 in step 160 if the oil injection pressure measured by pressure sensing switch 100 fails to reach the saturation level prior to timing ic 115 counting to q13 relay 210 will be de energized and power will be disconnected from the pump motor the flow diagram moves to block 180 where the alarm 220 is activated otherwise as shown in block 170 the oil injection pressure at pressure sensing switch 100 will reach the saturation level prior to timing ic 115 reaching the specified timeout interval the pressure sensing switch 100 closes prior to a timeout occurring where the timing ic 115.
