Page 6: Wiring
To protect the compressor from out of envelope operation, a compressor compartment sensor must be Compartment attached to the M input. The sensor is a NTC of Type Epcos M500 (Secop: 105N9617). It must be placed in Battery + Temperature the hottest area in a compressor compartment inside the air flow. -
Page 7: Input/Output Fmea
APPLICATION Input/Output FMEA This tables offers help with troubleshooting improper connections. A “–“ means no action at all, a green field is a temporary malfunction, which is no longer valid if the error is gone. Orange means possible auxiliary damaged, i.e., fuses or thermostats. Red means permanent damage to the controller. -
Page 8: Motor Driver
Motor Drives Sleep, Stop, and The BD Nano automotive controller features several operation modes depending on configuration. Operational States The motor speed and thereby the capacity of the compressor is set using the “Requested speed” parameter. During start up, the compressor runs at a lower speed, called “Start speed” (configurable, default 2,300 rpm), then “Requested speed”. -
Page 9: Typical Application Circuit
It is possible to replace a programming and speed-resistor by applying the target values using the Gateway in production. The Secop Gateway can also be a helpful tool for end of the line tests in production since all system Display relevant parameters can be obtained from Tool4Cool ®... -

Please see the chapter “Changing Parameter Settings” in the Tool4Cool operating manual, available at ® controller stops the motion and waits for the compressor restart time to retry the start attempt. secop.com/tool4cool All described parameters are available and editable via Modbus and Tool4Cool ® Compressor Start Speed The compressor start speed applies after successful start of the compressor. -
Page 11: Compressor Speed Protection
We strongly recommend enabling the feature for any production appliance. If disabled, Secop reserves the right to decline any warranty claims. Temperature cut-in/out for both cold and hot environment can be configured to be more restrictive. -
Page 12: Delays
Delays The BD Nano offers several options for delaying actions: Starting the fan before the compressor and extend its runtime after the compressor has stopped helps to equalize pressures in the refrigeration system. The reduced pressures support a soft and silent start of 1. -
Page 13: Fan Speed
Condenser Fan Fan Speed The controller features two registers to control the condenser fan speed. One located in an EEPROM cell, intended to be configured once in factory environment. The second is in the controllers RAM, intended to be overwritten by a master controller to actively control the fan speed. Both registers are percent values, 100% equal 12 V output, 0% equal 0 V. -
Page 14: Fan Soft Start
Fan Soft Start Thermostat The electronic unit is equipped with a digitally controlled thermostat. To make best use of the thermostat feature, be sure to configure it properly to fit it to the needs of the cooling appliance. The fan output can be configured to ramp up rather than hard switch on if enabled. This ramp up curve makes it possible to drive demanding fans. -
Page 15: Eco Mode
ECO Mode For a more economically cooling appliance, the integrated thermostat supports the ECO mode. The idea An additional overall benefit of the ECO mode is the reduced compressor noise at lower speeds. As the is to have the compressor running at low rpm during low load conditions and have it run at high rpm ECO mode aims to run the compressor at a lower speed than the configured maximum required speed, at high load conditions. -
Page 16: Communication Timeout
Product information is available via the read device identification (Encapsulated Interface Transport) Communication Timeout Modbus request. Refer to the Modbus Register Information (available from Secop on request) The communication timeout wait time can be configured, i.e. if a stopped communication is intentional for full documentation. -
