4.1.2 Error display messages
Any errors that occur will be displayed in the run mode. The errors will alternate with the
normal run mode display and will be prioritised. The errors will be latched and can only be
cancelled by pressing the 'OK' button. Once the error message has been cancelled the display
will show the next (if any) error.
Any continuous error will reinstate itself 2 seconds after it has been cancelled, and will be
indicated by a flashing exclamation mark (!).
Certain errors will also cause the 4-20 mA alarm signal to be initiated.
The error messages are displayed over two screens and are:
= Power interrupted.
= No signal from sensor.
(This can also activate the 4-20 mA alarm).
= Signal from sensor constant.
(This can also activate the 4-20 mA alarm).
= Flow above the maximum.
= Line conditions have changed from
superheat to saturation (only when pressure
sensor enabled).
