Parker Balston Model 9150
Hydrogen Generator

Hydrogen Flow
Indicators
The Parker Balston Model 9150 hydrogen generator has built-in system diagnostics to
monitor the operation of the generator and alert the operator in case of failure. There is a
Power Indicator
light on the front panel of the generator to signal the operational status of the
system (see Figure 10).
The control circuitry restricts the membrane cell current to a safe level and eliminates the
possibility of excessive hydrogen production. If a fault occurs and an indicator is illuminated,
follow the instructions in the
Troubleshooting
section to clear the fault.
Note:
See the
Explanation of Symbols
section on the loose sheet in this manual to match the
symbols on the generator to the descriptions listed below.
Hydrogen Flow Indicator
- The Hydrogen Flow Indicator light illuminates to indicate the cell is
generating hydrogen (see Figure 10).
Flow Check Bar Graph
- In normal operating mode (the side Mode Button is out), the bar
graph displays the percentage of flow produced by the system (see Figure 10). where the flow
is displayed from High (160 cc/min) to Low (less than 5 cc/min).
No Hydrogen Flow Indicator
- The No Hydrogen Flow Indicator light illuminates to indicate
the cell is no longer generating hydrogen (see Figure 10).
High Hydrogen Flow Indicator (Mass Leak) -
The High Hydrogen Flow Indicator (or Mass
Leak detector) illuminates to warn the user that the hydrogen demand is exceeding the sys-
tem capacity. This may be caused either from a leak in the piping to the equipment or it may
indicate the volume that is being filled is too large for the generator. The High Hydrogen Flow
Indicator will stay illuminated for approximately 10 seconds, then the unit will shut down and
the no hydrogen flow indicator will be illuminated. Once the fault has been corrected, press
the START button to reset the generator and initiate hydrogen flow (see Figure 7).

During long periods of shutdown or storage (>3 months), the generator should be run for
1-2 days every 3 months to ensure that the cell remains hydrated and the water quality
intact.
If the generator is being returned to Parker, contact the Technical Support Services Depart-
ment at 800-343-4048 for a Return Authorization (RA) number and new packaging if the origi-
nal is no longer available.
1
Turn the
Pressure Adjust
knob to zero (see Figure 7). Wait until the outlet pressure gauge
reads zero.
2
Drain most of the water from the water reservoirs using the Drain Port Insert (connected
to a length of tubing). Leave a half inch of water in the reservoirs to ensure that the cell
remains hydrated. Connect the drain port insert to the
Drain Port
located on the front
panel behind the gray door (see Figure 8). Drain the deionized water into a 4 liter contain-
er.
3
After the unit has been drained, press down on the metal tab on the top of the
Drain Port
connector to remove the Drain Port insert and tube (see Figure 9).
4
Remove the desiccant cartridge and store it in a moisture proof container. Replace desic-
cant vessel cap.
5
Pack the generator carefully in the original packing box or request new packaging from
Parker Hannifin. Be sure to display the RA number on the outside of the box for prompt
response.

In order to maintain the warranty on the generator,
ship the generator in a manner that
