Commissioning The Generator - Parker 20H-MD Guide D'utilisation

3.4 Commissioning 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.
1 Referring to the recommended set up, 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 blue then red, 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 revert to the default menu as shown.
The internal pressure ("ACT" pressure) of the generator will build up to the required
operating pressure ("SET" pressure).
3 Once the required pressure is reached, the outlet valve of the generator will be opened, as indicated by " F L O W " on the display, and
hydrogen will flow through the system piping and out through the atmospheric vent line.
Unless a high capacity moisture trap is fitted at the inlet to the application instrument, continue running in this state for up to one week to
reach the required purity. Failure to do so could damage the application instrument.
4 Close the 3-way ball valve to pressurise the system piping. Check for leaks and repair as required.
5 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
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.
