Ext. sensor connector (J2)
This connector is for an external ambient (system) temperature sensor, see section
System
temperature
. The input is designed for the Infineon KTY11-5 temperature dependent resistor
(Infineon ordering code Q62705-K245). Mating connector for J2 is Molex 7880-2. A ready-made
sensor with a 40 cm cable and connector is available as the PV-5127-TW40 accessory.
Batt. sensor connector (J1)
This connector is for an external battery temperature sensor, or a jumper, see section
Battery
monitor and charger
. The input is designed for the Infineon KTY11-5 temperature dependent
resistor (Infineon ordering code Q62705-K245). Mating connector for J1 is Molex 7880-2. A
ready-made sensor with a 40 cm cable and connector is available as the PV-5127-TW40 accessory.
From the factory, a jumper is installed, disabling the battery temperature control.
Pinheader (ST3)
This pinheader is for configuring the System temperature measurement, see section
System
temperature
. You can mount a jumper in the “10°C” position, in the “On-board sensor” position, or
you can leave it unconnected. The factory default is a jumper in the “10°C” position.
