5.13.24 Lockout log

The control box allows the logging of the type and number of lock-
outs that have occurred and keeps them even without the electri-
cal power supply.
The logs of the lockouts allows you to access the last 10 lockouts
(see paragraph "Programming menu" on page 31).
Once the programming menu page has been reached by press-
ing the reset button the last lockout is displayed, pressing 10
times displays the least recent lockout (each time the burner
reaches the lockout condition the oldest one is removed).
5 seconds after the last pressing of the buttons, the type of lock-
out is displayed, see paragraph "Fault diagnostics - lockouts"
on page 26).

5.13.25 Logging of burner operating parameters

The control box allows you to log the operating time of the
opening of the first stage gas valve.
That way, you can determine how much fuel has been
consumed during operation.
The frequency of the count is 1 second.
Saving to memory (eeprom) of the data occurs every 30 minutes
if the burner is on.
Saving to memory is carried out even if in the previous 30
minutes the control box was operating only for a short period of
time.
If the control box is cut off from the mains power supply between
one saving and the next (after 30 minutes) the information about
this interval is lost.
If in the interval between one saving and the next a lockout is
set, there is writing to memory that involves also the logging of
the operating hours.
Together with the operating hours also the number of the
burner's first stage valve openings is saved.
In the menu (see paragraph "Programming menu" on
page 31) it is possible to independently reset both the operating
hours meter and the meter for the number of openings of the first
stage valve that occurred.
 The number of openings of the first stage valve is a maxi-
mum: 16.777.215 (after which it is reset).
 The meter for the number of openings of the first stage valve
is a maximum: 65,535 days (after which it is reset).

5.13.27 Long pre-purging

If a long pre-purging is enabled, an initial pre-purging of 1min and
20 sec beyond the default pre-purging time (40 sec) is carried
out.
In recycles due to flame loss when operating, the long pre-purg-
ing is not carried out but only the pre-purging with the default time
(40 sec).
If there is a loss of air pressure during the long pre-purging, the
recycle involves a repetition of the pre-purging that is this case is
1 min and 20 sec added to 40 sec.
