Connecting the thermal probe

Attention:
In order to validate the IMQ-SECURITY SYSTEMS certification and comply with EN 54-4
requirements, installation of a thermal probe is essential.
This panel has an on-board connector (paragraph 4.2 - [O]) for a thermal probe (accessory item). The
ProbeTH thermal probe regulates the battery-charge system by interacting with the battery temperature,
this operating method avoids battery damage.
1. Disconnect the batteries (if already connected).
2. Connect the thermal probe (Figure 27 - [D]) to the connecter (paragraph 4.2 - [O]) on the
motherboard.
3. Using a strip of strongly-adhesive insulating tape (Figure 27 - [E]), attach the Thermal probe to one of
the batteries, in such way as to a provide optimized heat-transfer measurements.
4. Using a thermometer, measure the probe temperature.
5. Using the graph Figure 28 - Voltage charge in relation to the battery temperature find the optimized
heat-transfer measurement for the charge.
6. Using a voltmeter, measure the voltage on the AUX terminals (paragraph 4.2 - [U]).
7. Adjust the trimmer (Figure 29 - [B]) on the switching power-supply (Figure 29 - [A]) to the value
indicated on the graph.
