ACCESSING AND CHANGING JUMPERS
Follow these instruction to change jumpers for the Process Variable, Remote
Setpoint and Digital Inputs:
Equipment needed:
Needle-nose pliers (optional)
Phillips screwdriver (#2)
Wrist grounding strap
1. With power off, loosen the four front screws, and remove them.
2. Side the chassis out of the case by pulling firmly on the bezel.
3. Use
Figure 4.2 to locate the jumper connector to change.
4. Using the needle nose pliers (or fingers), pull straight up on the connector
and remove it from its pins, as shown in
Photo 2. Be careful not to bend the
pins.
5. Find the new location of the jumper connector (again, refer to
Figure 3.2).
Carefully place it over the pins, then press connector straight down. Make
sure it is seated firmly on the pins.
6. Make any other jumper changes as needed.
To alter output modules,
please refer to the next section, starting with Step #3.
7. To reassemble the controller, properly orient the chassis with board open-
ing on top. Align the circuit boards into the grooves on the top and bottom of
the case. Press firmly on the front face assembly until the chassis is all the
way into the case.
If it is difficult to slide the chassis in all the way, make sure the screws have
been removed (they can block proper alignment), and that the chassis is
properly oriented.
8. Carefully insert and align screws. Tighten them until the bezel is seated firmly
against the gasket.
Do not overtighten.
CAUTION!!
Static discharge can cause damage to
equipment. Always use a wrist
grounding strap when handling
electronics to prevent static discharge.
