2 T
Battery test. By applying 5V you can check whether the battery has an
output voltage >11.4Vdc. This information is given on the "
B
” terminal.
3
B
High impedance output if the voltage supplied by the battery is <11.4Vdc.
120
Ω
output if the battery voltage is >11.4Vdc.
This information is valid if "
T
" is active.
4 15
High impedance output if the voltage from the power supply is <12.4Vdc.
120
Ω
output if the voltage from the power supply is >12.4Vdc.
5
24
High impedance output if the voltage from the transformer on the "
24Vin
"
terminals is <18Vac.
120
Ω
output if the voltage from the transformer on the "
24Vin
” terminals is
>18Vac.
