(1) The measurement range is defined for a 50 % distention of the load cell.
(2) These are typical values with an active Sinc4 filter and measurement range of 2 mV/V
(3) To maintain the accuracy of the analog channel measurement, a system calibration with the sensor is required
whereby the null point and full-scale deflection are calibrated. The system must be re-calibrated when a sensor is
replaced or the measurement range changed. Basically, the null point calibration is performed followed by the
calibration for the full-scale deflection. The full-scale deflection can only be calibrated between 50 and 100 % of
the positive measurement range.

4.2 Notes
The signals recorded by the analog modules are very small, as compared to the digital sig-
nals. To ensure error-free operation, a careful wiring method must be followed:
• The DIN rail must have an adequate ground connection.
• The lines connected to the source of the analog signals must be as short as possible and
parallel wiring to digital signal lines must be avoided.
• The signal lines must be shielded.
• The shielding must be connected to a shielding bus.
• Avoid parallel connections between input lines and load-bearing circuits.
• Protective circuits for all relays (RC networks or free-wheeling diodes).
The ground bus should be connected to the control cabinet when possible!
Si possible la terre doit être connectée à l'armoire de commande!
IMPORTANT:
The S-DIAS module CANNOT be connected or disconnected while voltage is applied!
IMPORTANT:
Le module S-Dias NE PEUT PAS être inséré ou retiré sous tension.

4.3 Connection Variants
Two connection Types can be used when measuring with strain gauges:
4-wire measurement:
The advantage of this variant is that a 4-pin connector cable can be used for the strain
gauge. The voltage drop on over the circuit for the bridge voltage supply, however, cannot
be compensated.
6-wire measurement:
This configuration provides the advantage of voltage compensation using the bridge voltage
supply on the strain gauge directly.

5 Mounting
The S-DIAS modules are designed for installation into the control cabinet. To mount the mod-
ules a DIN-rail is required. The DIN rail must establish a conductive connection with the back
wall of the control cabinet. The individual S-DIAS modules are mounted on the DIN rail as a
block and secured with latches. The functional ground connection from the module to the DIN
rail is made via the grounding clamp on the back of the S-DIAS modules. The modules must
be mounted horizontally (module label up) with sufficient clearance between the ventilation
slots of the S-DIAS module blocks and nearby components and/or the control cabinet wall.
This is necessary for optimal cooling and air circulation, so that proper function up to the
maximum operating temperature is ensured.
