Cellwatch Frontier System Installation & User Manual
Section II – User Guide-90
An example of Frontier monitoring a charge event.
Low float current (continuity)
Frontier includes a low float alarm that is triggered when current measured is less than the intended
float charge. This can be indicative of a battery internal disconnect or possibly switched-off charger. This
limit must be less than the charge current limit, and a Float Charging Current Probe (FCCP) should be
used as the charge CT in a logical CT configuration.
Note: This alarm’s condition is set up specifically for use with FCCP units. This type of current probe
takes 20 minutes for readings to stabilize. Thus, a low float current alarm will not trigger until the
current measured by the FCCP is less than the low float current limit continuously for 20 minutes.
A low float current event takes lower priority to discharge and charge events. This means that a low
float current alarm will never trigger during the event of a discharge or charge. If a low float current
alarm has triggered, the detection of a discharge event or a charge event will cause the low float current
alarm to turn off.
