The following sections detail the display unit connectors used when installing
a single HSB Series LCD Display. The remaining connector details are
provided in Section .
Transducer Connection (master displays)
Before attaching it to the display, you will need to attach the connector nut and
split ring to the transducer cable. These items, plus a wedge tool, are included
in the transducer packaging.
CAUTION:
Take care not to pull on the cable – this can damage the transducer wires.
1. Feed the cable/connector through the 3/4" (19mm) diameter hole in the
surface where the display is mounted.
2. Slip the nut over the connector and push it past the connector and over the
cable.
3. Insert the wedge tool into the groove in the split of the split ring and slide
the wedge tool until its squared end is flush with the larger edge of the split
ring.
