2.2 Sentinel device
The Sentinel device is a digital transducer, which measures Voltage, Temperature and
Impedance of a 'Standby' Battery. Two types of modules exist: one for low voltage 2V bloc,
another one for high voltage (6V or 12V).
Mechanical drawings:
The module is equipped with two S-Bus ports (refer front view), internally connected in parallel
and with a power & sense connector (on rear view) towards the battery bloc:

Care must be taken to connect the Sentinel to the positive and negative terminals of the bloc
correctly.
Reversal of these leads may damage the Sentinel.
It must put on a clean and plane bloc area and fixed to it thanks to the ‘double-sided’ tape on
its back. Take care to place the Sentinel in order its LED on left side being easily seen.
The Sentinel module is sealed to comply with the relevant health and safety standards; under
no circumstances must it be opened. No object must be inserted into the module other than
the specified connectors. If this condition is not complied with, all warranties and compliance
are void.
