3.4 Starting up the Generator
Ensure that a suitable vent line is provided during the commissioning stage as hydrogen will flow from the unterminated
system piping.
In order to guarantee the optimum efficiency of the PEM cell, this generator must be installed and running within three
months of dispatch from Parker Hannifin. Failure to do this may invalidate the warranty. The generator will perform a 60
minute (1 hour) initialization sequence when powered for the first time. This sequence, which cannot be aborted, is
necessary to guarantee the correct hydration of the cell.
1
Referring to the recommended set up (figure 3), use the 3-way ball valve to isolate the application instrument from the
system and divert the flow to the vent line.
If a 3-way ball valve has not been installed, disconnect the application instrument from the system and connect the open
ended piping to a suitable vent line
2
Connect the generator to the electrical supply and switch it on at the wall socket. Turn the generator on at the power
switch (located on the rear of the generator) and wait.
The generator will perform a system check during which time the water bottle indicators will illuminate white then yellow,
the system check LED will flash, and the software version number, generator serial number and the company banner will
be displayed on the LCD.
On completion the generator will warm up and the
display will show “Initializing”. Once warm up is complete the unit will
revert to the default menu as shown in figure 10.
Note:
Upon first use, the generator may appear to stop building pressure while the separation chamber fills with water.
Should this happen, restart the generator.
3
The internal pressure (“ACT” pressure) of the generator will build up to the required operating pressure (“SET” pressure).
To achieve the required pressure at the process instrument, it is recommended that the set pressure of the generator be
10 psig above the required pressure (i.e. to achieve 50 psig at the instrument, set pressure of the generator should be 60
psig). Doing so will negate fluctuations in pressure due to the process and pressure drop within the process piping.
4
Once the required pressure is reached, the outlet valve of the generator will be o
pened, as indicated by “ LOAD ” on the
display. At this time, the hydrogen outlet port valve must be opened and hydrogen will flow through the system piping and
out through the atmospheric vent line.
5
Close the 3-way ball valve to pressurize the system piping. Check for leaks and repair as required.
6
Open the 3-way ball valve to divert the flow to the application instrument.
During start-up, the generator may revert to the last error mode it experienced. If this occurs press
.
When the error is cleared, the generator will continue with the start up procedure. If the error cannot be cleared by this
method follow the fault finding procedure in section 6 of this user guide.
If the pressure envelope of the system has been breached it will be necessary to run through this procedure when starting
the generator.
