It includes:
- Date and time of occurrence or change of status
- Alarm ID (unique ID for each alarm)
- The name of the alarm
- Current status
The history allows to know the evolution of the status of each alarm from the moment it appeared until its disappearance.
For example, it is possible to know when the fan fault alarm appeared (Activated), when it was manually acknowledged by the
technician (Acknowledged), and when the fault actually disappeared (Returned).
The management of the alarms in the buffer is of the FIFO type: the 1st entry is the 1st exit when the buffer is full in order to be able
to accept new ones. It is not possible to reset the buffer.
XXI. FILTERS REPLACEMENT
Following the replacement of the air filters, it is possible to reset the alarm filter (see XX.9 Acknowledgment of the filter alarm).
XXII. REPLACING THE INTERNAL MEMORY BATTERY
This procedure requires knowledge of proper ESD protection, i.e. an earthed wristband must be used!
When the alarm (48) "Internal Battery Error" is activated and the battery LED lights up red, the battery for backup of program
memory and real-time clock has become too weak. The battery is replaced as described below. A backup capacitor saves the memory
and keeps the clock running for at least 10 minutes after the power supply is removed. Therefore, if the battery replacement takes
less than 10minutes, there will be no need to reload the program, and the clock will continue to run normally.
The replacement battery must be of the type CR2032.
