Diagnostics
This chapter describes the fault diagnostics of the SMC Dialog Plus
controller. Further, this section describes the conditions that cause
various faults to occur.

Protection Programming

Many of the protective features available with the SMC Dialog Plus
controller can be enabled and adjusted through the programming
parameters provided. For further details on programming, refer to the
Advanced Setup section in Chapter 4, Programming.
The SMC Dialog Plus controller comes equipped with a built-in two-
line, 16-character LCD. The LCD displays the fault message on the
first line and the fault code on the second line.

Note: The fault display will remain active as long as control power
is applied. If control power is cycled, the fault will be
cleared, the controller will re-initialize, and the display will
show a status of "Stopped."
Important: Resetting a fault will not correct the cause of the fault
condition. Corrective action must be taken before
resetting the fault.
You can clear a fault using any of several methods:
• Program the SMC Dialog Plus controller for a Clear Fault, which
can be found in the Faults and Linear List groups.
• If a human interface module is connected to the controller, press
the Stop button.
Note: The stop signal will not clear a fault if Control Logic is
disabled (Logic Mask, parameter #85, equals 0).
