2.8.1. Errors of the gas controller
Detection of events that restrict or prevent correct operation of the autogas system is indicated by messages with descriptions in red.
Section “Active errors” lists the codes of current faults detected by the controller. If the cause of the fault is eliminated, the entry is moved to the “Error records” section. In other words, this means that a defect had been detected, but it is not currently active.
A “Delete” button for erasing recorded controller errors from the memory is located in the bottom part of the “Errors” tab, below the “Error records” section.
The following errors may appear during operation:
Description in AC STAG application
Gas injector missing
Meaning
Open circuit or fault of the specified gas injector
Low gas pressure
High gas pressure
Supply voltage too low
Gas temperature sensor missing
Reducer temperature sensor missing
Gas temperature sensor circuit shorted
Gas pressure dropped or kept below the allowed low limit within the specified time
Gas pressure 2x higher than the operating pressure for 60 seconds (usually associated with reducer problems)
Controller supply voltage decreased below 9 [V]
(usually associated with a failing battery)
Disconnected or disrupted circuit of the gas temperature sensor
Disconnected or disrupted circuit of the reducer temperature sensor
Gas temperature sensor shorted to vehicle grounding
Reducer temperature sensor shorted to vehicle grounding
Controller’s circuit for injectors supply failed
Reducer temperature sensor circuit shorted
Injector supply circuit failure
Solenoid valve supply circuit failure
Solenoid valve missing
Peripherals supply circuit failure
Connection with the switch failed
Overloaded or defective circuit or solenoid supply
Disconnected or disrupted circuit of the solenoid supply
Overloaded circuit of peripherals supply (PS-02 sensor, WPG-H gas level indicator)
LED 400/LED 401 switch not connected
Communication with the switch lost
Connection with LED 400/LED 401 switch interrupted
