Maintenance and Troubleshooting

5–6

Since the Push Button Module is part of an integrated system, you must

evaluate the entire system when a fault is detected. Start your

troubleshooting by asking these basic questions:

• Is the source power to the Push Button Module present?

• Do you have a communications light? If not, check your twin-axial cable

wiring. The blue and clear wires may be interchanged.

• Is the rack address set properly? Refer to Chapter 2.

• Are the baud rates of the Push Button Module and the Scanner Module

the same? Refer to Chapter 2.

• Is the Push Button Module the last in a series of modules, and has it been

identified as the last rack? Refer to Chapter 2.

• Is the communication connector securely plugged in at both the Push

Button Module end and the Scanner Module end?

• Have you changed the settings of any of the DIP switches? New DIP

switch settings are not acknowledged until power is cycled. Refer to

Chapter 2.

• On modules with a switch selectable power supply, is the 120/240 AC

voltage switch position correct?

• If applicable, is the fuse properly installed and in working order?
