8.1 901/9020 SIL - Failure Indications
In case of malfunctions, the following messages are displayed:
Failure
Code
Description
**Failure
Priority
F1.1*
The supply current to the connected transmitter is too high
>350 mA for 9020
>450 mA for 9010
Check the connected transmitter or a short-circuit between P+ and P-.
2
F1.2*
4-20 mA input protection failed
Voltage on the 4-20 mA input is higher than 5 V
For transmitters, check if a short-circuit between S+ and P+ exists. Check the
signal from the transmitter.
11
F1.3
Possible shortcut on passive detector side
The current voltage on pin P+ deviates from the stored voltage during calibration
by more than 1.8 V.
Recalibrate the detector.
Check for a shortcut between P+ and P- terminal.If detector or bridge current has
been changed then new calibration is always required.
4
F1.4*
Default configuration has been loaded
The factory default or user default configuration (See chapter 5.8 -
Access Code 53 Default Settings).
During start-up the factory default configuration was loaded because an invalid
configuration was found.
90
F1.5*
The connected transmitter is not delivering a constant current
Please check for proper function of the connected transmitter.
4 to 20 mA driver could be defective. 10
F1.6
The transmitter is consuming less current than set in Access Code 4 / P2
(For 3 wire transmitter setup in Access Code 52 / P3 only).
80
F1.7
The transmitter current is turned off
If a transmitter or digital input requires too much current (>350 mA for 9020
or >450 mA for 9010) or if a board temperature is outside of acceptable limits
(-20 to +75 °C), the transmitter/detector current is turned off.
Check if the transmitter or digital input are connected correctly.
2
F5.1
ADC convertor failure
The analog-to-digital converter is not working correctly. Unit has to be replaced.
80
F5.2
ADC Backup convertor failure
The backup analog-to-digital converter is not working correctly. Unit has to be
replaced.
80
F5.3
ADC convertor failure
The analog-to-digital converter is not working correctly Unit has to be replaced.
80
F5.4
Detector current cannot be set
Check detector connection.
(For passive detectors only) 20
F5.5
Testing voltage is too low
If voltage < 0.1 V on the S+ terminal is measured.
Check detector connection.
(For catalytic combustion detectors only)
