Curtis 3501 Manual -

The BDI provides critical battery state-of-charge information. The 3501 supports automatic battery profiling.

The 16-pin interface handles various communication and input signals: : SCI Receive (Rx) and Transmit (Tx). Pin 3 & 4 : CAN_L and CAN_L Termination. Pin 7 : Keyswitch Input (KSI). Pin 8 : MOSFET Output.

The Model 3501 is typically installed using a mounting bracket that fits panel thicknesses between 2.0 mm and 8.0 mm. curtis 3501 manual

Mount the aluminum backplate directly flat against a clean, unpainted metal surface. Use a thin layer of thermal joint compound (heatsink paste) between the controller plate and the mounting surface to maximize heat transfer.

Auto-ranging from 12V to 80V DC (9V to 100V DC). Operating Temperature: -40°C to +70°C. Pin 3 & 4 : CAN_L and CAN_L Termination

Restricts the maximum output duty cycle when the reverse input is active for safety. 0% – 100% 30% – 50%

Check the resistance of the main contactor coil. If the coil is shorted, it will destroy the internal driver of the controller. Replace the contactor if necessary. Code 4,1: Low Battery Voltage The Model 3501 is typically installed using a

Typically involves holding specific button combinations (refer to section 2.6 of the manual). Change Settings: Navigate through menus like 10 CHANGE SETTINGS (Maintenance), and 40 SET CLOCK Passcodes:
