Repair Procedures
(RP): System Repair or Expansion
through entries without changing values until you
reach the pulses per gallon entry for the meter being
replaced. At that step, edit the PPG value to the default
value of 0390 PPG. Continue procedure SP2 to the
end without changing other values.

To purge air from the system, dispense several
1-gallon jobs at a convenient bay, into a hand
measure container. Match the fl uid type to the fl uid
meter being replaced. Observe the dispensed 1-gallon
quantity to confi rm correct operation of the new meter
and removal of all air in the fl uid line.
10
Remove the alternate dispensing method for
temporary use prepared in step 1.
RP3
Replace Model 3120-032 Air
Solenoid Valve or 3120-033
Fluid Solenoid Valve:
1
Locate the smart Controller associated with the
valve under repair. At that controller, disconnect
the wire connector plug at the port matching the repair
valve. This will allow the Spectrum system to continue
dispensing at all stations except the one under repair.
2
Disconnect the two wire leads on the solenoid valve
to be replaced (old).
3
Close the hand shutoff valve adjacent to the sole-
noid valve to isolate from the system. Then remove
the old valve from the fl uid piping.
4
Install the new valve into the fl uid piping. Reopen
the hand shutoff valve when ports are connected
and tight.
5
Connect the two wire leads on the new solenoid
valve to the open wire ends of the solenoid cable.
Be sure connecting wires are clean, not frayed and
tightly secured with wire crimp lugs or screw caps.
Secure wiring with wire ties as needed.
6
At the smart controller, reconnect the port plug
which was removed in step 1.
7
At the queuing console, conclude or cancel all
dispenses in queue. Then cycle the power switch
on the back of the console OFF/ON and allow the self
test routine to cycle. The display should then show
“SPECTRUM 100, IDLE”.
8
To purge air from the system, dispense two 1-gallon
jobs at the repaired dispense point, into a hand
measure container. Observe the dispensed 1-gallon
quantity to confi rm correct operation of the new valve
and removal of air.
RP4
Replace Model 3120-031
Ready Light:
1
Locate the smart Controller associated with the
Ready Light to be replaced. At that controller, dis-
connect the wire connector plug at the port matching
the defective Ready Light. Refer to ”WIRING DETAIL,
SMART CONTROLLER”,
[Figure 26, Page 20]
. This will
allow the Spectrum system to continue dispensing at
all stations except the one under repair.
2
Disconnect the two wire leads on the Ready Light
to be replaced (old), at the junction with solenoid
valve wires and wire ends of the solenoid power
cable. If needed, refer to “WIRING DETAIL, FLUID
SOLENOID VALVE AND READY LIGHT”,
[Figure 29,
Page 21]
.
3
Remove the old ready light by hand-pushing it out
of its 1/2” mounting hole.
4
Install new ready light into the vacant 1/2” hole,
feeding connection wire in fi rst.
5
Connect the new ready light wires at the wire
junctions where they were removed in step 2. If
needed, refer to
[Figure 29, Page 21]
. Secure with wire
ties as needed.
6
At the smart controller, reconnect the port plug
which was removed in step 1.
7
At the queuing console, conclude or cancel all
dispenses in queue. Then cycle the power switch
on the back of the console OFF/ON and allow the self
test routine to cycle. The display should then show
“SPECTRUM 100, IDLE”.
8
To check operation of the new light system, dis-
pense a 1-quart job the repaired dispense point.
Observe the Ready Light for proper function, then
cancel the job at the console.
