Timer (Model LPG-2E)
P1061
Location:
The timer is located inside the hopper housing just
behind the left solenoid.
Test Procedure:
1. Disconnect grinder from the power source.
2. Insert the leads of a voltmeter set to read at least
120 volts AC, along side the red wire (terminal 8)
and the white wire (terminal 2) of the harness plug.
Place the Off/On/Start switch in the “ON” center
position. Connect the grinder to the power source.
The indication must be 120 volts AC.
3. Disconnect the grinder from the power source.
If voltage is present as described, proceed to step
#4.
If voltage is not present as described, refer to the wiring
diagram and check the grinder wiring harness.
4. Place the hopper selector switch in the left posi-
tion.
5. Insert the leads of a voltmeter set to read at least
120 volts AC, along side the red wire (terminal 8)
and the orange wire (terminal 10) of the harness
plug. Place the Off/On/Start switch in the “START”
lower position. Connect the grinder to the power
source. The indication must be 120 volts AC for the

#7.
If voltage is not present as described, replace the
timer.
7. Place the hopper selector switch in the right posi-
tion.
8. Insert the leads of a voltmeter set to read at least
120 volts AC, along side the red wire (terminal 8)
and the violet wire (terminal 9) of the harness plug.
Place the Off/On/Start switch in the “START” lower
position. Connect the grinder to the power source.
The indication must be 120 volts AC for the set gate
time and return to 0 volts.
9. Disconnect the grinder from the power source.
If voltage is present as described, proceed to
step#10.
If voltage is not present as described, replace the
timer.
10. Insert the positive (+) lead of a volt meter set to read
at least 120 volts DC, along side the black wire (ter-
minal 7) of the harness plug and insert the negative
(-) lead along side the white/black wire (terminal 6)
of the harness plug. Place the Off/On/Start switch
in the “START” lower position. Connect the grinder
to the power source. The indication must be 120
volts DC for the set gate time plus clean out time
and return to 0 volts.
If voltage is present as described the timer is operating
properly.
If Voltage is not present as described, replace the
timer.
Removal and Replacement:
1. Disconnect the main wiring harness plug from the
