Installation and wiring
Caution
Proper function of the tension measuring amplifier is only guaranteed with the
recommended application of the components. In case of other arrangement, heavy
malfunction can be the result. Therefore, the installation instructions on the following
pages must be followed strictly.
Caution
Local installation regulations are to preserve safety of electric equipment. They are not taken
into consideration by this operating manual. However, they have to be followed strictly.
7.1
Mounting and wiring of the measuring amplifier
Variant for insert card support block (EMGZ421)
The insert card support block can be mounted in a control cabinet. Wiring to the terminals
is done according to „7.3 Wiring diagram: Variant for insert card support block“ (fig. 5).
The electronic unit then will be inserted into the insert block. It will be locked by a stop
hook (fig. 3).
Variant with separate housing (EMGZ421.E)
The housing can be mounted in a control cabinet or directly beside the machine. All
connections are led through glands to the screw terminals and connected according to
„7.4 Wiring diagram: Variant with separate housing“ (fig. 6 and 7).
7.2
Mounting the force sensors
Mounting of the force sensors is done referring to the FMS Installation manual which is
delivered together with the force sensors.
Wiring to the terminals of the electronic unit is done according to wiring diagram (fig. 5
resp. 6).
Note
Connecting the shield of the signal cable to the measuring amplifier
and
to the force
sensor may cause ground circuits which may interfere the measuring signal massively.
Malfunction can be the result. The shield should be connected only to the measuring
amplifier. On the „force sensor side“, the shield should stay open.
