If a warning or alarm condition exists:

The top line of the display on the Pump Display Module will change to 'WARNING' or
'ALARM', together with an error number.

The bottom line of the display will show the warning or alarm message or (for some errors)
will be blank.

The warning or alarm LED on the Pump Display Module will flash.
To acknowledge the warning or alarm, press the ENTER button. If the warning or alarm
condition has cleared, the warning or alarm LED will go off. If the warning or alarm condition is
still present:

The warning or alarm LED will stay on.

•
If the warning or alarm condition has an advisory message (see Section 6.14), the display will
show two lines which describe a simple check which you can make to identify the cause of
the fault and to rectify the fault. When you have read the message, press the ENTER button
again; the display will then change to normal display: see Section 5.2.
5.8
Manual shut-down
WARNING
If you intend to do any maintenance on the iL system which does not require the system
to be isolated from the electrical supply after you have shut it down, do not disconnect the
Pump Display Module or release control from the Pump Display Module (see Section 5.3).
If you do, the iL system could be started by another Module.
Note:
Press the Cancel button on the Pump Display Module to cancel a shut-down request.
Use one of the methods described in Sections 5.8.1 and 5.8.2 to manually shut down the iL
system. Ensure that it is safe to shut down the iL system before you select shut-down.
5.8.1
Normal manual shut-down
Note:
The purge time for the normal manual shut-down option is preset to 15 minutes as supplied. This
purge time can be configured for your application.
We recommend that you use the Switch Off/Auto menu to shut down the iL system in normal
operating conditions. This method provides a 15 minute period after shut-down selection
during which you can purge the foreline.
