5.2.2 Inactive Alarms
There are two sections in the Alarm list: an active alarm section and an inactive alarm section. The APX Control
System can hold up to 16 alarms in the combined lists. The lists can be read via the display screen or using TRU-
Tech. Alarms in these sections are in the order in which the alarms activate and inactivate, respectively. On
startup, all alarms are moved to the inactive list. If an inactive alarm becomes active, the alarm is moved from the
inactive list to the active list.
Each alarm can only be present in either the active or inactive list at any given time. As conditions change, alarms
may be moved from the active list to the inactive list and back.
Alarms are also recorded in the data recorder. They are recorded at the time they occur (become active), and the
time they become inactive.
Instructions for reading and clearing the Inactive Alarms are provided in Figure 5.3. for a complete list of Alarms
and troubleshooting information Refer to Section 9.
NOTE
The Inactive Alarm List is also called the Technician’s List. Only qualified refrigeration technicians
should access the inactive list. It is not intended for the use of drivers or advanced users.
