If one or more CRITICAL ERRORS occur, the relay K3 energizes and the
corresponding error (system error) will be displayed. IR5002 interrupts its
measurements when a CRITICAL ERROR occurs. The error code will be output
via both serial interfaces.
All CRITICAL ERRORS with code and short description are listed in the table
below:
Code N0.
System error Short description
1
RTC-Error
Error of the internal real-time clock of the
microcontroller. IR5002 defective!
2
ADC-Error
Error in the analog/digital converter of the
AD unit. IR5002 defective!
3
Display-Error Error of the display or its control circuit.
IR5002 defective.
4
I
2
C Error
Error of the non-volatile memory. IR5002
defective!
5
Temperature Temperature inside the casing of IR5002 or the
Error
external coupling device AG5002 is too high.
Measurements will be stopped as soon as the
temperature inside the coupling device exceeds
150
°
C.
6
No-PE
There is no PE connection to IR5002.
Touching the device may result in harmful
effects to persons. By all means, the device must
be checked by a qualified electrician.
7
Polarity
Wrong polarity of the network coupling L+/L.
Check system coupling!
8
Low-UN
System voltage is too low! System voltage is
below the pre-set value MINIMUM SYSTEM
VOLTAGE ALARM. Check system voltage
and connection.
