4.1The most common option

4.1.1.Remote Connections

This option requires the I/O board option.

The hydrogen generators are fitted with an optional remote control feature, which allows the user to check the status of the machine from a remote position, and to start/stop the production of hydrogen. The contacts used in the remote control are potentially free relay contacts. The contacts can be configured via software as normally-open or normally-closed (see the Configuration section). The maximum voltage and current ratings for the contacts are 1A / 48V. The pin configuration of the remote connector is shown in the table below.

Remote connector pin configuration

Pin / Description
1+2 / Start (12-30 VDC polarity not important)
3+4 / Standby
5+6 / Reaching external pressure
09+10 / Low water level
11+12 / Bad water
13+14 / Change water
7+8+15 / Not affected

4.1.2.Cascading

This option requires the I/O board option

The RS-485 interface allows up to 10 generators to be operated in parallel mode. There are two modes available.

The generators are connected with an external non return valve to a gas line. The pressure must be controlled with an external pressure regulator. The outlet pressure is fixed to 10.3 bars. This mode allows up to 10 generators in a cascading group.

How does cascading work:

The communication of the generators is done via the RS-485 Interface. For a correct communication each generator need a unique ID number. Each generator must know how many generators are connected in the cascading group. As soon as the generators are powered up, one generator becomes the master, and controls the others (slaves). If there is a problem with the master, one of the slave generators will become the master.

Every generator can be forced to be the master, by entering into the menu you will see the function “force to master” , just select this function and acknowledge.

When a generator is the master, you can see the letter “M” in the menu button, while the slaves show the letter “S”.

The cascading function will only work properly if the gas outlets on all the generators are connected to the same gas line.

5.7Schemas

5.7.1.Fluidics

The hydrogen generator produces pure hydrogen (and oxygen as a by-product) by the electrolysis of wa- ter. The key element of the generator is an electrochemical cell assembly which contains a solid polymer electrolyte. No free acids or alkaline are used. De-ionized or pure, distilled water is the only liquid which may come into contact with the cell. As this is consumed it must be refilled from time to time as re- quired. The generated hydrogen gas is accumulated in the hydrogen/water separator and the desiccant housing. The internal pressure is controlled by a pressure transducer. The outlet pressure is controlled by a proportional valve. The hydrogen is dried by passing through the automatic dryer for the “NM style” and by a static dryer for the “PG style”. The hydrogen then passes through outlet port at therear.

6.3Placing the generator

The hydrogen generator must be placed on a flat, level, vibration-free, shock-free surface. Do not place the generator over a source of heat, as this may cause the device to overheat. The unit should not be in contact with any other objects on any side, and the air inlet must not be blocked. Leave at least 30 cm of free space at the rear for ventilation. Do not operate the generator in a sealed or unventilated room, or in close proximity to open flame or other sources of ignition. Do not operate the generator at below freezing temperatures. Operation is guaranteed at operating temperatures between +15 and +40°C.

Normal precautions for any hydrogen supply should be taken when using the generator.

DO NOT use in sealed or unventilated rooms.

DO NOT use in close proximity of open flames or other sources of ignition.

6.4Gas connections

Pure dry hydrogen at regulated pressure is available at the hydrogen outlet port at the rear of the generator. This port must be connected to 1/8" tubing using a stainless-steel or copper Swagelok connector. Teflon connectors are not suitable. The pressure at this port is adjusted and shown on the display. The hydrogen relief port at the rear of the unit can be connected to an exhaust hood or other vent system.

Plug the Oil-Free air source in the inlet (AIR IN) of the generator connecting between the Air Filter provided in the package.

Zero Air can be used by the 1/8” rapid fitting (AIR OUT)

The line from the relief port should never connect in such a way that back pressure can develop.

6.5Electrical connections

Check the setting of the voltage selector on the rear of the unit.

The set voltage is indicated in the white square on the inlet power filter. To change the voltage, proceed as follows:

Using a small screwdriver, remove the voltage selector insert.

Replace the voltage selector insert so that the white arrow points to the correct voltage

6.6Filling the water tank

The FID TOWER PLUS has an internal water tank included in its chassis. The tanks must be refilled with demineralized water with conductivity below 2uS.

Follow the steps in order to fill correctly the automatic water tank system.

  • Fill the Refilling tank provided in the package with demineralized water (below 2uS)
  • Connect the external water tank fitting to the refill fitting placed in the front of the FID TOWER PLUS
  • The tank must be placed higher than the generator. (water refill the tank system by gravity).
  • Disconnect the tank when the water has reach the MAX level showed in the same side of thefitting.

DISCONNECT THE WATER REFILLING TANK WHEN MAX IS REACHED. IF THIS IS NOT OBSERVED IT CAN CAUSE OVERFILL.

CAUTION!

To prevent contamination of the cell assembly, it is important to use only deionized or distilled water in the generator. Water containing metallic impurities will contaminate or damage the cell, and will void the warranty.

6.7Installing the deionizer bag

In order to protect the cell from bad water quality, it is necessary to use a deionisation bag. Inspect the bag thoroughly for holes or tears, indicated by loose deionizer beads on the outer surface. If the bag is damaged in any way, discard and replace it with a new one. Only use original parts (see Spare Parts). Wash the deionizer bag in deionized water before proceeding.

Insert the free end of the “T” fastener through the hole in the centre of the holder, until it is securely fastened. The bag should not block the outlet at the bottom of the tank. Once in place, the bag should not be allowed to dry out.

This bag is to be inserted in the internal tank via the front panel:

  • Push the 2 fasteners showed by red arrows.
  • Pull out the tank compartment.
  • Unscrew the top cap and insert the deionizer bag.
