5. Using the Volumetric Event History Download Software
confirm that the times up to the first ‘Low Battery Plug In Cord’
alarm, and time difference between this alarm and the ‘Battery
Too Low Plug In Cord’ alarm, is within the following
specification.
Pass:
A battery shall be deemed to have passed its test if the unit runs for a
minimum of 51/2 hours on DC power, at a rate of 100ml/hr (99ml/hr
for 505/3100) before the first ‘Low Battery Alarm Plug In Cord’ is
triggered.
There must be a minimum of 30 minutes between this alarm and the
‘Dead Battery Plug In Cord’ alarm that will occur before the pump
powers down.
In use this 30 minutes would allow up to 5 sets of ‘Low Battery Plug
In Cord’ alarms to be raised. When cancelled the ‘Low Battery’ alarm
will be triggered again every 6 minutes if the AC power supply has
not been connected.
Fail:
A faulty battery would be one that does not meet this specification. In
this case the battery should be replaced.
It is recommended that pumps should be run overnight as this would
avoid creating a disturbance to staff caused by the ‘Low Battery Plug
In Cord’ and ‘Dead Battery Plug In Cord’ alarms that occur before the
unit’s power down.
Event history should then be downloaded and analysed to confirm
that the battery time periods meet the requirements above.
