18.12 Auto-restart
This pump offers an auto-restart feature. If active on power loss, it restores the
pump when power returns to the operating state it was in when power was lost. It
does not operate when powering down in the middle of a dose: when the pump is
restarted, it will await a press on the
START
key to begin the interrupted dose
again. Auto-restart is retained while the pump is switched off. When the pump starts
running, look for the
!
symbol on the display. This
!
symbol indicates that the pump
is set for auto-restart.
In the fourth screen of the Setup menu select
Auto-restart
using the
UP
and
DOWN
keys. Press
ENTER
to confirm your choice.
The pump displays a screen allowing the user to activate auto-restart. Use the
UP
and
DOWN
keys to choose
On
or
Off
and press
ENTER
to confirm the
decision.
If
Off
is chosen, the pump returns the user to the fourth screen of the Setup
menu. The auto-restart facility will not operate.
If
On
is chosen, the pump returns the user to the fourth screen of the Setup
menu, where an exclamation mark (
!
) is now visible. This mark confirms that
the auto-restart feature is in place and will operate the next time power is lost
and restored.
Alternatively ...
Stop the pump. Turn off the mains power switch at the rear of the pump.
Hold down the
START
key and turn on the mains power switch. The
!
symbol
shows on the display.
Start the pump. If the mains supply is interrupted the pump will automatically
restart when the mains power returns.
To remove auto-restart switch off the mains power at the rear of the pump.
Hold down the
STOP
key and turn the mains power switch on. The
!
symbol
does not appear.
Do not use auto-restart for more than 100 starts per
hour. We recommend remote control where a high
number of starts is required.
