Reaction B. Temp.Sensor Failed
Pt1000 temperature sensor measurement is out of limits.
1. Check the connection labelled 'HEATER PT1000' on the
Interconnection Board.
2. If the error persists, contact your local ABB representative.

Reaction Block Temp. High / Low
>20 °C (36 °F) above or >20 °C (36 °F) below
The measured temperature is more than 20 °C (36 °F) above or
below the programmed control temperature.
If the temperature exceeds the programmed control temperature
by more than 20 °C (36 °F), the analyzer enters automatic shutdown
mode and the heater supply is switched off.
1. Check that the sample and ambient temperatures are within
the quoted limits.
2. If the error persists, contact your local ABB representative.

Pre-Heat Temp.Sensor Failed
Pt1000 temperature sensor is out of limits.
1. Check the connection labelled 'PRE-HEATER PT1000' on
the Interconnection Board.
2. If the error persists, contact your local ABB representative.

Pre-Heat Temperature High / Low
>20 °C (36 °F) above or >20 °C (36 °F) below
The measured temperature is more than 20 °C (36 °F) above or
below the programmed control temperature.
If the temperature exceeds the programmed control temperature
by more than 20 °C (36 °F), the analyzer enters automatic shutdown
mode and the heater supply is switched off.
1. Check that the sample and ambient temperatures are within
the quoted limits.
2. If the error persists, contact your local ABB representative.

Internal Communications Failed
Communication failure between the main board and the display
assembly.
1. Check the ribbon cable connection of the main board.
2. Contact your local ABB representative.
Internal Electronics Temperature Too High / Low
The internal temperature of the electronics enclosure is either too
high or too low.
1. Check the 'Electronics' value displayed on the 'Measurement
Status' page within 'Diagnostic Information' – see
Section 12.3, page 60.
2. Check that the ambient temperature is within quoted limits.
3. Contact your local ABB representative.
