View Active Alarms
Check and clear active alarms on the Vector 8500
Use the ALARM key to view any active alarms on the unit. Alarms are stored in the Alarm List in the main microprocessor and can 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 last alarm that occurred is displayed first.
In Driver mode, alarm descriptions will only display when the ALARM DESCRIPTIONS Functional Parameter is set to YES (Table 3–2). In Advanced User mode or Technician mode, the alarm description always displays following the alarm number.
Next to the ACTIVE ALARMS screen name in the status bar, the total number of alarms and the position of the highlighted alarm in the list are shown.
Press the UP (▲) or DOWN (▼) key to scroll through the list of alarms.
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 5 seconds.
You can also clear active alarms by turning the control system OFF and then back on using the START/RUN-OFF switch.
The inactive alarm list may only be viewed in Technician mode. Only qualified refrigeration technicians should access the inactive alarm list. It is not intended for Drivers or Advanced Users.
For a complete list of alarms, their meanings, and troubleshooting steps, refer to Section 7 of the manual.
