Fault Display (20-HIM-A6)
When you use the SMC-50 control module with a 20-HIM-A6, the HIM
displays the fault information.
Figure 48 - Fault Display
Clear Fault
You can clear a fault using any of the following methods:
• Program the SMC-50 to automatically clear a fault using Restart Enable,
Parameter 135 or 264.
• Press the SMC-50 control module HOLD TO TEST, PUSH TO RESET
button.
• Connect a N.O. push button to Option Input #1 (terminal 11) or # 2
(terminal 10). Option Input #1 or #2 must be programmed for Clear Fault
using Parameter 56 or 57.
• Cycle the control power to the SMC-50.
IMPORTANT Resetting a fault does not correct the cause of the fault condition. You must
take corrective action before you reset the fault.
The fault display remains active as long as control power is applied. If you
cycle control power, the fault is cleared, the control module re-initializes,
and the display shows a status of Stopped unless the Fault condition still
exists.
You can press Esc to get to another programming/diagnostic list, but the
SMC-50 control module is still in a faulted state.
