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.
Even with the remote stop function disabled, the pump
could still start if the remote auto/manual toggle input
is used to toggle the pump into analogue mode.
