Fig. 29: Heater MDH-48-BY

The Heater Cable 48 V is available in different length (e.g. 2 m, order no. 1014064, see Fig. 30). To

connect the connector of the heater to the rear side of the control unit (“Heater”), use the heater

cable.

6.3.3.5 Connecting a Cooler

As an example. the Flow Control Valve FCV-AC 6.0 M12 (order no. 1016265, see Fig. 31) is shown

to demonstrate the connection of a cooler.

Fig. 31: Flow Control Valve FCV-AC 6.0 M12

To connect a cooler to the MDC, you need the Connection Cable for FCV-AC/HF M12 to MDC

(length 2 m, order no. 1016252, see Fig. 32, page 55).

Fig. 32: Connection Cable for FCV-AC/HF M12 to MDC

With the connection cable, you can connect the cooler connector of the FCV-AC 6.0 M12 to the

rear side of the control unit. Connect the air outlet of the flow control valve to the inlet of the

microdispensing valve (marked with “IN”). Use a suitable hose. Connect the air inlet of the flow

control valve to the compressed air supply.

6.3.3.6 Connection Diagram

The picture below offers an overview of how to connection all parts with cables and hoses (using

one flow control valve and one heater as example).

6.4 Valves with Air cooling

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

finishing the cable connections of the valve. Use 4 mm hoses.

Fig. 34: Valve with air cooling connected

One end of the hose has to be pushed onto the air inlet of the valve (in); the other one is

connected to the air supply.

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

the valve. You can extend this connection with an air hose. Push one end of the air hose onto the

adapter. When running the hose to the air supply, 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 hot melt

application or other high temperature applications, 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: Quality class 1

max. number of particles/m³: 0.1 – 0.5 µm: < 20000, 0.5 – 1 µm: < 400, 1 – 5 µm: < 10

• Water content: Quality class 4

max. pressure dew point +3 °C

• Residual oil: Quality class 2

0.1 mg/m³ max.
