5.2 Visual and Audible Fault Indication
An EPD failure is usually indicated by a visual and audible alarm. In most instances
the EPD will display an error code on the LCD and the LED will flash. The default
audible alarm is as follows:
Alarm rate:
___ ___ ___ ___
slow intermittent rate
If alarm mute is enabled for the fault alarm the sounder can be silenced and the alarm
Led extinguished by the action of pressing and holding the button. The fault alarm can
also be set to self mute after a timeout period in order to preserve battery life. If this
happens the unit will give a short beep every 30 seconds thereafter.
An EPD conveys faults to the user by a number of displays, e.g.:
♦ Initialisation Error ( ---- on the LCD )
♦ Communications Error ( ==== on the LCD )
♦ Error Code ( Fxxx on the LCD )
♦ Blank Display
♦ Other faults (e.g. display lock-up, no heartbeat etc.)
