Alarm/Alert Codes
Table 10 lists PIC6 alert codes. Table 11 lists PIC6 alarm codes.
Alerts do not cause machine shutdown and are typically automati-
cally reset when the situation returns to normal, while alarms typi-
cally result in machine shutdown. See the Alarms menu in Fig. 60.
Fig. 60 — Alarm Menu
Displaying Alarms
The alarm icon on the interface (see the section Icons on
page 12) indicates unit status as follows:
• A flashing red icon shows that the unit is operating but
there is an alert.
• A steady red icon shows that the unit has been shut down
due to a fault.
The Current Alarms menu displays up to eight alarm codes that
are active on the unit. Table 11 lists alarm codes.
Resetting Alarms
When the cause of the alarm has been identified and corrected, the
alarm can be reset either automatically or manually (depending on
the type of alarm). To reset the alarms, enter the Reset Alarm
menu, select the Alarm Reset icon, select Yes in the pop-up win-
dow, and execute.
In the event of a power supply interrupt, if Auto Restart Option
is set to ENABLE in the Option Configuration menu, the unit re-
starts automatically without the need for an external command.
A manual reset must be run from the main menu via the Reset
Alarms Feature.
All information regarding solved alarms is stored in the Alarm
History. Alarm History stores last 50 alarms even after alarms
have been corrected or reset.
