2.4 Alarm / error display messages
If an error occurs, an exclamation mark (!) will flash in the bottom left corner of the run
display (see Figure 2). The details of the error or alarm will appear on a new message
screen (see Figure 3), which can be accessed by scrolling through the run menu. Pressing
and holding the
button for 3 seconds can clear a message and re-energize the alarm
relay(s). If the cause has not been corrected, the same message will reappear. If the error
or alarm is of a latching type, only the message will disappear. The alarm relay will remain
de-energised until the correct pass code is entered in the commissioning menu. If more
than one error or alarm has occurred, the next message will appear (in priority order) after
the previous one has been cleared. See Section 9, 'Fault Finding'.
If there are any problems with the product, error or alarm will appear. The example shows a
power failure.
