5.3.2 Installation of the Valve as Part of a Machine
Preferably mount the valve on an automatic XYZ table or in a similar device
(XYZ positioning system) . Stable seat at the fixture of Z axis is imperative, as the
valve should not become loose during the dispensing process. For this purpose,
two M4 hex screws have to be inserted to a depth of 4 mm, through the bores
located at the narrow side of the valve. Their distance center to center
amounts to 45 mm. To improve accuracy when positioning the valve on a re-
ceptacle, additionally use the alignment bore and the long hole, located on the
narrow side of the valve as well.
IMPORTANT NOTE! (Corrosion)
In order to prevent corrosion, all parts used in connection with the valve
(screws, fix-
ing plates etc.) should consist of stainless steel, nonferrous metals or galvanized steel.
5.3.3 Wiring of the MDS 3200
+
The valve is connected to the control unit MDC 3200
+
by means of a four pin actuator
(red)
and five pin sensor plug
(yellow)
. The plugs are protected by coding against interchanging by
mistake.
DANGER! (Switch off before removing plug)
Never attempt to attach or remove one of these plugs, when the system is connected
to mains.
CAUTION! (Plan your cable connections carefully)
Make sure to plan your cable run carefully, when considering the wiring, especially if the
valve is included into a more complex system. Your cables cannot hang too loose, since then
they might start to swing and get damaged, because of the vibrations of the valve. On the
other hand you might need enough length in your cables, if the valve is moved in the z-axis.
IMPORTANT NOTE! (Switch off for disconnection)
Before you separate the valve from the control unit, switch OFF the whole system and
disconnect it from the power supply.
5.3.3.1 Actuator Cable
Power to the piezo element is supplied by the actuator cable, which is wrapped with a red
antikink sleeve. The voltage range is -30 V to 120 V
(bipolar operation)
.
Step 1: Plug the cable into the correspondingly labeled connector on the rear side of the
control unit and screw it in place.
Step 2: The other end, equipped with a four pinned LEMO connector
(corrugated sleeve),
has to be connected to the red marked, looped cable attached to the valve.
IMPORTANT NOTE! (Connecting cables)
Verify during the connecting procedure that the red points on the plugs point towards
each other.
