In combination with a, transducer which is capable to handle tension and compression forces, an
analogue output of ± 10 volts is available. However, if a unipolar voltage is needed anyway, it is possible
to set the zero point of the transducer to 5 volts of the output. This zero-point elevation is also necessary
for the analogue current output. (5 V ± 5 V equals 12 mA ± 8 mA) To lift the zero point to 5V the solder
point LP03 needs to be set.
4.4 Setpoints (option GW)
The setpoint characteristics are as follows:
GW2 = MAX; GW1= MIN
(GW GrenzWert = SetPoint)
Notice:
Other setpoint characteristics on request.
The 2 red LEDs in the lid signal the state of the relays, thus the setpoints.

Within the permitted range (SP1/MIN < current measuring value < SP2/MAX) all set-point relays are
activated. The relays drop out if a setpoint is under-run SP-1 or exceeded SP-2 or if the supply voltage
fails.
Notice:
The setpoints are not pre-adjusted by the manufacturer. These settings have to be made by the
customer.
The maximum switching capacity is 30V/0,5A
4.4.1 Setpoint settings
The setpoints can be set freely over the complete range of the measurement by using the potentiometers
P-100 and P-101 on the additional pcb (Althen 112). The adjustment may be executed either with loaded
sensor(-s), or by measuring the desired voltage on the pcb (Althen 112) on the measuring points (GW-
MP.1/2). The scaling of the GW-Test-signal equals
to the analogue output voltage.
The relays should be used for control signals only,
instead of switching heavy electrical loads.
The external wiring must be executed in a manner
that noises are suppressed.
