Appendix A – Sentinel™ Information
The Sentinel
’s™ job is to detect when a charger is finished charging and a battery is ready to be selected.
Normally the battery is connected and the charger turns on. The Sentinel
™ observes the voltage as it
changes over time. When the charger turns off, the Sentinel
™ can detect that and signal that the battery
has just gone through a complete charge. Sometimes chargers have a cool down timer that will make the
“charge complete” light come on several hours after the charger actually turns off. In these cases, the
Sentinel
™ will correctly terminate when the charger actually turns off and not when the “charge complete”
light illuminates on the charger.
In addition to a normal charge cycle, the Sentinel
™ can terminate in two other ways. Both happen in a
situation where the charger does not turn on. This can either be because the battery is over-discharged
and the charger does not start, or if a fully charged battery is connected and the charger senses this and
does not start.
Status LED’s
The Sentinel
™ has three LED’s on it that can help diagnose what the Sentinel™ is doing.
Green LED
A solid green light indicates a good connection to the Controller.
All Sentinels
™ should have a solid green light
.
Upon initial connection, the green light will flash
fast, then slower, before settling at solid green
.
If the green light remains fast flashing, check the
wire connection to the Sentinel
™.
Amber LED
When the amber light is on, the battery is connected.
If the amber light does not turn on, check the quick tap to ensure that the pins have fully
penetrated into the cables.
Blue LED
A bright blue with momentary flashing light indicates the next battery to pick in that pool.
If you do not want to use the blue light as a pick light indicator, it can be turned off in the
settings panel. Click “Settings,” then “Sentinels™,” then “Pick Light,” and turn it off.
