View Active Alarms
Check and clear active alarms on the X4-7700 unit
Use the ALARM key to view any active alarms on the unit. Alarms are stored in the Alarm List in the Microprocessor Stepper Module and may also be viewed in the MessageCenter.
With the system powered up (START/RUN-OFF switch in the START/RUN position) or in PC mode, press the ALARM key.
If there are active alarms, the alarm number will be displayed preceded by the letter "A" (Active alarm). The status bar shows the total number of alarms and which alarm is currently highlighted.
In Driver mode, alarm descriptions will only display when the ALARM DESCRIPTIONS Functional Parameter is set to YES (see Table 3–2). In Advanced User mode or Technician mode, the alarm description always displays following the alarm number.
Press the UP (▲) or DOWN (▼) key to scroll through the list of alarms. The last alarm that occurred will be the first alarm displayed.
Press the CLEAR ALARMS soft key. The display will show an "ACTIVE ALARMS CLEARED" message to confirm the alarms have been cleared.
If there are no active alarms, the display will show a "NO ACTIVE ALARMS" message and return to the default display after five seconds.
You can also clear active alarms by turning the APX Control System OFF and then back on using the START/RUN-OFF switch.
For a complete list of alarms, alarm descriptions, and troubleshooting recommendations, refer to Section 7.3.
The inactive alarm list may only be viewed in Technician mode (Section 5.2.2). Only qualified refrigeration technicians should access the inactive alarm list. It is not intended for Drivers or Advanced Users.
