INSTALLING THE AT10.1
23
Note the following:
•
You should set the Float and Equalize voltages to the values
recommended by your battery manufacturer for 77 °F / 25 °C.
•
When you enter the Edit Mode to adjust the Float or Equalize voltage
(see Section 2.3.2), the front panel meter displays the 77 °F / 25 °C value
for the Float or Equalize voltage, even if the battery is warmer or cooler
than 77 °F / 25 °C.
•
The actual output voltage of the AT10.1 may be different from the value
displayed on the front panel meter, if the battery is warmer or cooler than
77 °F / 25 °C.
•
Use a digital meter to measure the actual output voltage of the AT10.1.
If you know the temperature at the temperature compensation probe, you
can use the graph below to determine that the output voltage is correct.
•
If the battery temperature goes below 32 °F / 0 °C, there will be no
further increase in AT10.1 output voltage. Likewise, if the battery
temperature goes above 122 °F / 50 °C, there is no further decrease in
output voltage.

EXAMPLE: Suppose you have a lead-acid battery whose temperature is
100 °F / 37.8 °C. As shown on the graph, the output voltage should be
approximately 97% of the 77 °F voltage. If the float voltage is set on the
front panel to 132 Vdc, the actual output voltage will be:
132 x 0.97 = 128 Vdc
1.12. INSTALLING FOR REMOTE COMMUNICATION (OPTIONAL)
Refer to separate Operating Instructions ( JA0102-04 ).
1.13. INSTALLING FOR FORCED LOAD SHARING (OPTIONAL)
Refer to Appendix F on page 92 or Operating Instructions (
JA5054-00
).
