is inaccurate, the meter calibration factor in the console
program may need to be adjusted. At the console,
repeat procedure: “Fluid Identifi cation”,
[Procedure
SP2, Page 37]
. Be sure meter calibration factors (pulses
per gallon) are set to the default value of 0390 PPG.

If dispense quantities remain inaccurate after com-
pleting step one, the meter calibration factor may
be custom calibrated to the exact fl uid and conditions
of use in your system. Estimate the amount of error
by observing the calibration marks on the container.
If the amount dispensed was less than one measured
gallon, then increase the PPG factor proportionately
for that fl uid in “Fluid Identifi cation”,
[Procedure SP2,
Page 37]
. Alternately, if the amount of dispensed was
excessive, decrease the PPG factor in similar manner.
Example
: For fl uid 1, 5W20, meter calibration factor
was 0390. One gallon is authorized and dispensed
into a measure which reads 5 cubic inches less than
one gallon. To adjust, increase the program PPG
factor to 0395 (increase of one unit per cubic inch of
error). Then test-dispense another gallon. Continue
to fi ne-adjust the PPG value up or down until exactly
one gallon is dispensed.

If a job is authorized and does not shut off auto-
matically at the predetermined amount, check all
wiring between the console and the impulse meter
for that fl uid. Verify correct wire placement per color
codes shown
[Figure 25, Page 19 and Figure 26, page
20]
. If the error occurs at only one station, audit the
placement of solenoid wiring: fl uid 1 to port 1, fl uid 2
to port 2, etc. Be sure wire ends are properly stripped
and attached to terminations. Be sure the
correct
black
ground wire is used, as cable-wound with each color-
coded positive wire.
6
If a fl uid dispensed amount remains incorrect
and/or varies substantially from job to job, and
if all other troubleshooting steps have been applied
without resolution, then replace the impulse meter per
procedure: “Replace Model 3120-103 Impulse Meter”,
[Procedure RP2, Page 57].

Assuring a Suitable System
Power Supply
1
The AC power adapters supplied with the Spectrum
Queuing Console and Ticket Printer will provide
adequate, well-conditioned power to the system in
almost all installation sites. However, additional power
handling equipment may provide more reliable opera-
tion if the site has: (a) incoming voltage outside the
range of 110-120 VAC, or (b) frequent power distur-
bance due to electrical storms or (c) frequent power
transients due to a heavily loaded site power network.
2
Balcrank recommends the installation of an Uninter-
ruptable Power Supply (UPS) device, such as those
used for personal computers, with an output rating of
80 Watts or more, particularly where power source
risk factors exist as identifi ed in step 1, above. Oper-
ate the UPS from the site power receptacle, and plug
the console AC power adapter cord and ticket printer
power cord into the UPS.
3
Output power within the Spectrum System may be
checked using a voltmeter. Voltage will be 23 to 25
volts DC at the Queuing Console and 16 to 24 volts at
the most distant Smart Controller or Solenoid Valve.
