Troubleshooting
This chapter contains information on troubleshooting the FanMaster.
Important: Power must be supplied and circuit breaker CB1 in the
FanMaster enclosure must be set to “ON” in order for the
PanelView terminal and MicroLogix controller to run. If the
PanelView screen or display on the MicroLogix controller is
dark (off), set CB1 to “OFF” and check the power source and
wiring to the unit. Once the power source and wiring has been
verified, set CB1 to “ON”.
FanMaster Status You can determine the operating status of the FanMaster in the following
ways:
•
Alarm indications. An alarm banner (example shown below) will display
on the PanelView terminal to indicate a problem. Refer to
FanMaster
Alarms on page 4-2 below for more information.
•
Air Handler Unit Diagram screen on the PanelView terminal. This screen
provides an overview of a typical AHU configuration and current
FanMaster readings. If a value is out of range (OOR) or above a set limit,
or a communication fault (Comm Fault) has occurred, in addition to the
display of an alarm banner (described above), “OOR” or “Comm Fault”
will display in place of the reading for the affected device. Refer to
Air
Handler Unit Diagram Screen on page C-3 for more information.
•
FanMaster Faulted indicator light. This light, located on the front panel
of the unit, will turn on when an error condition exists in FanMaster and/
or connected drive (if installed). The light will turn off when the error
condition is cleared.
•
FanMaster Faulted signal. An optional dry contact output that remains
closed when FanMaster is energized and is not faulted and opens when
FanMaster is de-energized or is faulted. This output can be monitored by
an external system for indication of proper FanMaster operation. Refer to
Figure B.2 on page B-3 .
