    Monitoring System) you purchased a high quality and reliable measuring system for battery power supplies. We thank you for your faith in EMCOTEC GmbH and assure you that you have made the right decision! Years of experience in development and manufacturing of electronic systems went into the DPSI BMS.
  • Page 4 DPSI BMS Operating Manual Version 1.0 Due to the manifold information indicated by the DPSI BMS, malfunctions in the receiver set can be detected: Sticky control rods or defective servos can be diagnosed due to higher current consumption. Eventual malfunction of a battery or in the battery switch (e.g.
  • Page 5 DPSI BMS Operating Manual Version 1.0 Three printed circuit boards, equipped on both sides with most modern parts allow for optimal space usage and are integrated into a stable and ergonomic housing. Usage of pin-and-socket connectors allow for simple exchange of connector cables and guarantees maximum flexibility.

    DPSI BMS Operating Manual Version 1.0 5. Optional Accessories 5.1. DPSI BMS Accessory Set The DPSI BMS accessory set contains two connector cables, 30 cm (11.8”) each, which are put in between the DPSI BMS and the battery switch (1 cable for the 1 channel version). Therefore, no soldering work is necessary if MPX connectors are already in use (from the battery to the battery switch).

  • Page 10: Mounting Instructions

    DPSI BMS Operating Manual Version 1.0 6. Mounting Instructions 6.1. Mounting of the DPSI BMS The DPSI BMS is designed as a cockpit instrument and therefore can be mounted as such (especially interesting for scale models). Of course, mounting on a small board inside the fuselage is also possible. The mounting place should not be exposed to extreme vibrations (as is the case at a fuselage’s side wall without a strengthening frame).
  • Page 11 DPSI BMS Operating Manual Version 1.0 Connector clamping with bracket: When using battery switches, the DPSI BMS is simply put in between the batteries and the battery switch. This means: both batteries are disconnected from the battery switch and connected to the inputs of the DPSI BMS.

    DPSI BMS Operating Manual Version 1.0 7. Soldering of the Battery Connectors In case connector cables are manufactured by the user for connection to the DPSI BMS, correct implementation must be observed. The MPX high current connectors are marked + and – on their soldering side. This marking must be strictly observed! The cables are first stripped (approx.
  • Page 14 DPSI BMS Operating Manual Version 1.0 Soldering Multiplex connectors: Hint: It is necessary to use one shrink hose per cable (see photo) for isolation and not to put a shrink hose over both cables! There must be enough space between the positive and negative wire to accommodate the bracket.

  • Page 15: Charging Instructions For Batteries

    DPSI BMS Operating Manual Version 1.0 Hint: Due to its design, the DPSI BMS is not polarity proof! Please make sure, that the batteries are always correctly connected, i.e. the red wire corresponds to positive and the black wire to negative. Better double check! 8.

  • Page 16: Initial Operation

    DPSI BMS Operating Manual Version 1.0 9. Initial Operation Initial operation, On/Off, Status Display: The DPSI BMS is simply put in between battery and consumer (e.g. between two LongGo batteries and a DPSI RV system). Turning On/Off can take place in two different ways: Automatically turning On/Off Manually turning On/Off 9.1.
  • Page 17 DPSI BMS Operating Manual Version 1.0 However, automatic turning on only functions if current flows from battery 1! If battery 1 is not loaded (but battery 2), the DPSI BMS is not turned on. Hint: Whenever the current from battery 1 exceeds 100 to 150 milli amps, the DPSI BMS automatically turns on.

  • Page 18: Manually Switching On/Off

    BMS are supplied by battery 1. The micro controller and the LC display get their voltage from battery 1! As soon as the DPSI BMS is turned on, “EMCOTEC Germany” is displayed for approx. 2 seconds in the LC display. Thereafter, both voltages of the batteries are displayed (BMS 2 channel version) and the DPSI BMS is in normal operating mode.
