9.4 DATA LOGGING
During operation, the C-More Control Panel continuously monitors and logs data associated
with operational events, faults and sensor readings associated with the boiler system.
Descriptions of these data logs are provided in the following sections. The basic procedure for
accessing each data log is described in section 9.3 step 10.
9.4.1 Fault Log
The C-More Control Panel logs the last 20 faults (0 – 19) starting with the most recent (#0).
They can be viewed in the front panel display or via the RS-232 port. The Fault Log cannot be
cleared. If the Fault Log already contains 10 faults, the earliest fault is overwritten when a new
fault occurs. A sample Fault Log display is shown in Table 9-1.
