The value shown as the device status is the total of the codings for the existing
errors.
Example: error on T
F
and T
R
(Err1 and Err3) results in error value 5 for the device
status.
Err1 1
Err3 4
Total (= device status): 5
7.2 Logbook
Malfunctions, control offsets and limit violations of fl ow/output are entered in the
logbook. The following applies:
Control offsets are entered whenever the actual value deviates by more than •
10K for at least 30 minutes
Limit violations are entered whenever the pulse rate remains more than 10% •
too high for at least 30 minutes
To view the logbook entries, select parameter SP03 in the SERVice level (see
Chapter 3.3).
The entries can be called up as follows. When SP03 is called up, the access
code can be entered. This is “0123”. After entering the access code you are taken
to the individual entries. The year in which the last entry was documented is
displayed fi rst. You can switch to the years in which at least one entry was made
by rotating the rotary knob. Pressing the rotary knob takes you to the next level,
in which the days (DD.MM) of the relevant year on which an entry took place are
displayed. You can select a day by pressing the rotary knob and show the times
(HH:MM) at which entries were made on the relevant day.
Press the knob to view the device status (for coding, see Chapter 7.1.2) or the
control offset or the limit violation. Press the ESC key to move back one level, or
several times to leave the SP03 level.
The same symbols are used for the control offset or the limit violations that
are also used in the normal display of the measured values (radiators etc.). By
turning the knob, you can change between the display of the recorded setpoint
and the excessively-deviating actual value. If the fl ow rate is too high, it is
displayed as a percentage.
A repeated fault is entered afresh only if it no longer existed in the meantime. The
logbook can hold a total of 100 entries. When this number has been reached, the
oldest entries are overwritten (circular buffer).
