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. The connection between the force sensors
and the electronic unit is done using 4x2x0.75mm
2
[AWG 18] shielded twisted pair
cable. (With cable length below 15m, 4x2x0.25 mm
2
[AWG 23] is also suitable.) The
cable must be installed separate from power lines.
Wiring to the terminals of the electronic unit is done according to the wiring diagram.
If two force sensors are used per measuring point, the cables are wired parallel (ref. to
wiring diagram). If wiring is made using 6 wire circuit the solder bridges must be
modified (ref. to „9.2 Configuring the electronic unit“).
Force sensor excitation can be made using 5VDC (default) or 10VDC (ref. to
„9.2 Configuring the electronic unit“).
Note
The force sensor signal consists of only a few mV and is therefore susceptible to
external influences to the cable. To increase immunity to interfering use one pair of
the twisted pair cable for +signal and –signal.
Note
Connecting the shield of the signal cable to the electronic unit
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 electronic
unit. On the „force sensor side“, the shield should stay open.
8.4
Mounting the brake amplifier or the drive unit
The brake and brake amplifier or drive unit and motor will be mounted according to
manufacturer’s specification. Herein is no additional information written due to the
wide variety of suitable types. Wiring is done according to the wiring diagram.
If an AC drive unit is used, the energy produced in the motor while braking must be
led off to a brake resistor or equivalent.
Danger
The Tension Controller has no built-in „Emergency Stop-function. However he can
drive brakes with high kinetic energy and drive units with high performance.
Depending on the kind of possible malfunctions, full braking or complete release may
cause heavy damage of man and/or machine. The same applies also for drive units.
Therefore, the person responsible for system design has to establish a security concept
that is providing appropriate emergency procedures for the possible malfunctions.
