6.3.3.2 Sensor Cable

This cable wrapped in yellow is provided to transfer data from the sensor integrated in the valve

to the control unit. Connect it as described below.

Fig. 19: Connecting the sensor cable – step 1

– Step 1: First, fix the sensor cable to the corresponding socket on the rear side of the control

unit.

Fig. 20: Connecting the sensor cable – step 2

– Step 2: The five-pin connector with a corrugated sleeve has to be connected to the yellow

marked, looped cable attached to the valve.

INFORMATION

Connecting cables

Verify during the connecting procedure that the red dots on the plugs point towards each other.

INFORMATION

Release latch for disconnection

To secure the connectors there is a latch, which you have to release before disconnection. You

have to grip the corrugated outhousing. Pull back the outhousing of the male connector to

release the latch (see Fig. 21, page 50). Then pull both connectors apart without losing the grip

and they will separate.

Do not pull at the cables!

6.3.3.3 Mains Cable

Power to the control unit is supplied by the black mains cable.

IMPORTANT NOTE

Type plate

Do not connect the system to the mains, before having checked the type plate of the model you

want to install (mains voltage, 110 V AC or 230 V AC).

– Step 1: Plug the cable into the socket at the bottom of the rear side of the control unit.

– Step 2: Connect the cable to the power supply.

– Step 3: Press the ON/OFF button, located on the rear side of the control unit.

INFORMATION

Valve not connected

If the valve is not connected, an error message (“199 Valve Error – Escape for Auxi.“) appears on

the screen. Switch OFF the system, disconnect it from the mains and complete the installation

before continuing. Alternatively, you can press the [ESC]-key. When confirming it with [Enter],

you change into the Auxiliary Mode (see paragraph 7.13, page 76).

6.4 Valves with Air cooling

If you want to air cool your valve with compressed air, you have to connect the air hoses to the

compressed air supply after finishing the cable connections of the valve. Use hoses with an inner

diameter of 4 mm.

Abb. 22: Valve with air-cooling adapters

The air-cooling adapters are equal. Therefore, it does not matter which one you use as inlet, and

which one as outlet. Push end of the hose onto the air inlet of the valve you chose. Connect the

other end of the hose to the air supply.

The second connector represents the outlet, evacuating the heated compressed air from the

valve. Push one end of the hose onto the connector. When running the hose away from the

valve, take care not to impair functions of the system, or to disturb operators during their work.

For air-cooling, you should use a compressed-air pressure of about 2 bar. For a high temperature

application, you should set the pressure higher, at up to 4 bar.

IMPORTANT NOTE

Quality of compressed air

Quality of compressed air should comply with DIN ISO 8573-1.

The pneumatic supply used for cooling of the valve should be free of fine dust and condensate

and correspond to classes 1, 4, 2 according to DIN/ISO 8573-1.

• Solid particles: max. particle number/m³: 0.1 – 0.5 µm: < 20000, 0.5 – 1 µm: < 400, 1 – 5 µm: <

10 = Quality class 1

• Water content: max. pressure dew point +3°C = Quality class 4

• Residual oil: max. 0.1mg/m³ = Quality class 2
