Connecting the Battery Temperature Probe (Option)
When the battery temperature probe option is ordered with the charger, a temperature probe is connected
to the charger’s Interface Board and the probe and wires coiled and tied near the Interface Board, behind
the front panel.
To connect the battery temperature probe:
1.
Open the front panel. Loosen two quarter-turn captive screws at the right edge of the panel. Swing the
panel open.
2.
If not already connected, connect the probe’s three wires into P2, then plug P2 into J2 on the Interface
Board as shown in Figure 2-6.
3.
Route the probe to the battery string. Cable length is approximately 25 feet (8m).
4.
Determine which battery cell or group of cells will have the highest operating temperature.
5.
Determine the charge/discharge status of the battery string. Connecting the probe may result in a
momentary battery string open circuit when the terminal bolt is removed.
CAUTION
DO NOT
proceed if the battery string is in a high
charge or discharge state.
ATTENTION
NE PAS
procéder si la batterie est en haute
recharge ou en mode décharge.
6.
Remove the bolt holding the intercell battery strap in place. Insert the bolt through the battery
temperature probe ring lug, through the strap, and into the battery terminal. Tighten the bolt as
recommended by the battery manufacturer.
7.
Bundle and secure any excess wire.
During commissioning, enable battery temperature compensation using the front panel keypad and 2-line
display. (See Section 4.3.4.2)
