8.4.2 Operation Time Log
The Operation Time Log consists of a string of ASCII records stored in non-volatile memory
within the C-More Control Panel. Events such as power-up, ignition and turn-off are time
stamped. Data logged while the unit is running are run-length encoded. Data is logged or the
run-length incremented every 30 seconds. For a new run record to be logged, the fire rate or
flame strength must change by more than 5%, or the run mode must change. At steady-state,
the run-length is allowed to reach a maximum of 30 minutes before the record is logged. This
means that no more than 30 minutes of data can be lost if the unit loses power. Table 8-2 shows
a sample Operation Time Log for a unit:

The Operation Time Log can only be accessed through the RS232 interface using a laptop or
other terminal device. Ten operation time records are displayed for each T command entry. The
operation time log can be cleared ONLY by factory authorized personnel using the Clear Log
option in the Factory menu.
NOTE
The Sensor (S) Log can store up to 1200 records. Therefore, to view the
most recently logged record, enter “S” followed by 0 (zero) and then press
Enter (i.e. S0
order, enter S and press Enter. To go back 200 or 700 records, enter S200
or S700, etc. and press Enter.
8.4.3 Sensor Log
The sensor values can be logged at a different rate if needed by setting the Sensor Log Interval in
the Diagnostics Menu. The log interval can vary from once every minute to once every day.
