1. Remove the BE1-11g from service and de-energize it.
2. The contact-sensing input jumpers are located behind the rear terminal blocks that are used for
input connections. Using a 7/64” hex tool, remove the rear terminal block(s) associated with the
input(s) that you want to configure. Observe all electrostatic discharge (ESD) precautions when
handling the BE1-11g.
3. Using the input labels on the rear panel as a guide, locate the appropriate jumper terminal block
that is mounted on the circuit board. Each terminal block has two sets of pins. With the jumper as
installed at the factory, one pin should be visible when viewed from the back of the unit. This
configuration allows the inputs to operate at the higher end of the control voltage range. Figure 27
illustrates the location of the contact-sensing jumpers. The jumpers are shown in the HIGH
position.
4. To select operation at the lower end of the control voltage range, install the jumper across the two
pins using needle-nose pliers. Use care when removing and installing each jumper so that no
components are damaged.
5. When all jumpers are positioned for operation in the desired control voltage range, reinstall the
rear terminal block(s).
6. Using a 7/64” hex tool, tighten the screws to 10 in-lbs.

The following paragraphs describe how to locate and remove/change the contact-sensing input jumpers:
1. Remove the BE1-11g from service and de-energize it.
2. Remove the drawout assembly by loosening the two thumbscrews and pulling the assembly out
of the case. Observe all electrostatic discharge (ESD) precautions when handling the drawout
assembly.
