Table of Alarms
The alarm signal consists of a code, the format being “Ernn” (nn is a 2-figure number identifying the type of alarm, eg: Er00, Er25, Er39….).
When more than one alarm occurs at the same time, the one with the lowest number will be shown first; (e.g. simultaneous alarms Er00 and
Er01). Er00 will be shown alternating between the display and the main screen.
If the measurement on the main display is incorrect, in the event of an alarm, the alternate alarm code will alternate with “----“.
All possible alarms are listed in the table below with their respective codes and the relative utilities blocked:
