Cause
Test of internal CJC sensor
CJ.ER
CJC sensor defect or
temperature outside range
Checksum test of the configuration in FLASH
FL.ER
Error in FLASH
Communications test 4501 / 4222
NO.CO
Connection error
Check that input signal matches input configuration
IN.ER
1) Error levels on input
Check that saved configuration in 4501 matches module
TY.ER
Configuration is not 4222
! All error indications flash once per second. The help text explains the error.
1) The error is reset by switching off and then switching on the supply voltage to the module.
