Troubleshooting
All troubleshooting activities should be performed by suitable personnel using reason-
able care.
Warning: Any troubleshooting or service activity which requires removal of the genera-
tor cover should be done using extreme caution. Exposed AC may be present.
Symptom
Course of Action
No Power
Check power source and connections to the power source.
Check terminal connections and power cord.
Check power source fuses.
Check generator fuses.
Refill /Empty Water
Completely fill DIO Resin Bed Reservoir with deionized water.
Auto -Water fill port is blocked / plugged.
DIO water supply shut off, ie.. Gravity or Pressure lines closed off.
Consult factory if display does not change status.
Hydrogen Overflow
Mass leak detected in system / downstream. If the H
2
pressure drops below 10 psi, the
“HYDROGEN OVERFLOW” will be displayed. Shut down then restart generator.
Hydrogen demand exceeds generator capacity. Check capacity of equipment and piping
downstream and install a flow control device. Shutdown then restart generator.
Check internal system piping for leaks. Shutdown then restart generator.
Low Output Pressure
Hydrogen demand exceeds generator capacity. Check capacity of equipment and piping
downstream and install a flow control device. Shutdown then restart generator.
Check external system piping for leaks. Shutdown then restart generator.
Check internal system piping for leaks. Shutdown then restart generator.
No Hydrogen Delivered
Check power connections (see above).
Check water level. Generator will shut down if water level is below the EMPTY level.
Customer installed shutoff valve is closed; open valve.
Check piping for leaks.
Consult factory.
Low Zero Air Pressure
Check inlet air pressure. Pressure drop up to 4 psid (0.3 bar) is normal. Minimum inlet air
pressure is 40 psig (2.8 barg).
Check flow demand and overflow condition. Flow demands in excess of capacity may cause
high pressure drop through generator.
Check generator for leaks.
Excess Hydrocarbons
The Zero Air has not reached adequate temperature . Allow a minimum startup, warm up pe-
riod of 55 minutes .
Check downstream Zero Air flow demand. If flow capacity of generator is exceeded, the ZAG
tower will be below the desired operating temperature and Hydrocarbon removal will be af-
fected.
An excessive pressure drop (greater than 4 psig/0.3 bar) may cause a high pressure drop
through generator.
If demand exceeds capacity, install a flow controller downstream from the zero air output.
Excessive Moisture
Dessicant is saturated; change dessicant.
in the Gas Stream
Cell Voltage Above Limit
Check resin bed. If color has changed to orange then replace resin. Drain and flush water from
system 3-4 times to remove impurities from water reservoir. Restart. If message still appears,
then run generator for 10-15 minutes to cycle water through cell, then drain and refill again. If
problem still persists consult factory.
If no resin color change has occurred, consult factory.
