Jumper Installation (Step 1)
Four sets of jumpers are located on the right side of the circuit board on
the back of the faceplate. Three jumpers set system voltage to 12 volts,
24 volts, or 48 volts. The fourth jumper dims the backlight on the
display to conserve power and improve accuracy when longer cable
runs are used. See Figure 5 for jumper locations.
To enable a selection, carefully slide the jumper over the top of both
pins. This is called installing the jumper.
To disable a selection, carefully slide the jumper over only one of the
pins. This is called removing the jumper.
To select and set the voltage:
◆
Install the jumper over the pins that correspond to the voltage of the
system. See Figure 5 for the location of the voltage jumpers.
