WARNING – Death or injury can result from static electric
shocks.
Moving webs of material can produce large static voltage
potentials. Protect against electric shocks by installing a
conductive connection between the terminal marked with the
PE symbol, pin 5, and the PE circuit of the building or
machine.
CAUTION – Never place electrical cables under mechanical
strain. Always provide mechanical support of wiring with
either clamps or flexible or rigid conduit.
All wiring must comply with the essential requirements of
the appropriate standard(s) and is the responsibility of the
installer.
Wiring to the digital load cell amplifier must be insulated
copper wire with a temperature rating of at least 80⁰C. The
wire size must be at least 0.34 mm
2
(22 AWG). Use twisted
pair cable for the power. Use shielded cable for the load cell
and analog output wiring.
1.
Connect a 24 VDC +/-10% power supply to pins 3 and 4
of the terminal blocks. Pin 3 should be positive and pin 4
should be negative. See Figure 2.
2.
Connect the PE of the building or machine to terminal
block pin 5.
Note: The negative power connection, pin 4, is internally
connected to the PE connection. This connection is only
used for EMC compliance.
3.
Connect one or two load cells to terminals 6, 7, 8, and 9.
See Figure 2. If using non-MAGPOWR half-bridge load
cells, see Figure 3 for wiring.
4.
Calibrate the load cells by following the procedure
starting on page 4-5 (Precision) or 4-8 (Weightless).
Figure 2 on the next page shows the complete DLCA wiring.
