7.5. Errors during operation
If errors occur during normal operation, the HOME.x pages
will show:
• the name of the error on the PV display
• the value of the setpoint or control output on the SV
display (only on models 1650 and 1850).
• a scrolling message with errors detected, on display SV
(model 850) or on display F (models 1650 and 1850).
The most common error messages are:
Lou Process variable is below minimum scale limit
(parameter LO.SCL on I.MAIN).
High Process variable is above maximum scale limit
(parameter HI.SCL on I.MAIN).
Err PT100 in short circuit or input values below minimum
limits (for example, thermocouple with incorrect
connection) or 4...20 mA transmitter broken or not
powered.
Sbr Sensor broken or input values above maximum limit.
