Figure 12-38. Contact Sensing Jumper locations
2.
Locate the two jumper terminal blocks that are mounted on the Digital Circuit Board. The Digital
Circuit Board is the middle board in the assembly and the jumper terminal blocks are located on
the component side of the circuit board. Each terminal block has two sets pins. With the jumper
as installed at the factory, one pin should be visible when viewed from the side of the unit. This
configuration allows the inputs to operate at the higher end of the control voltage range. Figure
12-38 illustrates the location of the jumper terminal blocks as well as the position of a jumper
placed in the high voltage position.
3.
To select operation at the lower end of the control voltage range, install the jumper across the
two pins. Use care when removing and installing each jumper so that no components are
damaged.
4.
When all jumpers are positioned for operation in the desired control voltage range, prepare to
place the drawout assembly back into the case.
5.
Align the drawout assembly with the case guides and slide the assembly into the case.
6.
Tighten the screws.
