- The electronic unit is a dual voltage device. This means that the same unit can be used in both 12V and 24V power supply systems. Maximum volt-age is 17V for a 12V system and 31.5V for a 24V power supply system. Max. ambient temperature is 55°C. The electronic unit has a built-in thermal protection which is actuated and stops compres-sor operation if the electronic unit temperature gets too high.
Installation (Fig. 1)
- Connect the terminal plug from the electronic unit to the compressor terminal. Mount the elec tro nic unit on the compressor by snapping the cover over the screw head (1).
Power supply (Fig. 1)
- The electronic unit must always be con nec ted directly to the battery poles (2). Con nect the plus to + and the minus to -, otherwise the elec tronic unit will not work. The electronic unit is pro tec ted against reverse battery connection.
- For protection of the installation, a fuse (3) must be mounted in the + cable as close to the battery as possible. 15A fuse for 12V and 7.5A fuse for 24V circuits are recommended.
- If a main switch (4) is used, it should be rated for a minimum current of min. 20A.
- The wire dimensions in Fig. 2 must be observed.
- Avoid extra junctions in the power supply system to prevent voltage drop from affecting the battery protection setting.
Battery protection (Fig. 1)
- The compressor stops and restarts again according to the designated voltage limits meas-ured on the + and – terminals of the electronic unit. The standard settings for 12V and 24V power supply systems appear from Fig. 3.
- Other settings (Fig. 4) are optional if a connection that includes a resistor (9) is established between terminals C and P.
- In solar applications without a battery, a 220 kΩ resistor is recommended. In AEO (Adaptive En-ergy Optimizing) speed mode, the BD compressor will always adapt its speed to the actual cooling demand within a random operation voltage of 9.6 to 31.5V.
Thermostat (Fig. 1)
- The thermostat (7) is connected between the terminals C and T. Without any resistor in the control circuit, the compressor with electronic unit 101N0210, 101N0220, or 101N0240 will run with a fi xed speed of 2,000 rpm when the thermostat is switched on. With the thermostat directly connected to terminal C, the electronic unit 101N0300 or 101N0320 will adjust its speed to the actual cooling demand.
- Other fi xed compressor speeds in the range be-tween 2,000 and 3,500 rpm can be obtained when a resistor (8) is installed to adjust the current (mA) of the control circuit. Resistor values for various motor speeds appear from Fig. 5.
Fan (optional, Fig. 1)
- A fan (5) can be connected between the terminals + and F. Connect the plus to + and the minus to F. Since the output voltage between the terminals + and F is always regulated to 12V, a 12V fan must be used for both 12V and 24V power supply systems.
- The fan output can supply a continous current of 0.5Aavg. A higher current draw is allowed for 2 seconds during start.
LED (optional, Fig. 1)
- A 10mA light emitting diode (LED) (6) can be con-nected between the terminals + and D.
- In case the electronic unit records an operational error, the diode will fl ash several times. The number of fl ashes depends on what kind of operational error was recorded. Each fl ash will last ¼ second. After the actual number of fl ashes, there will be a delay with no fl ashes, so that the sequence for each error recording is repeated every 4 seconds.
| Number
of lashes |
Error type |
| 5 | Thermal cut-out of electronic unit (If the refrigeration system has been too heavily loaded, or if the ambient temperature is high, the electronic unit will run too hot). |
| 4 | Minimum motor speed error
(If the refrigeration system is too heavily loaded, the motor cannot maintain a minimum speed of 1,850 rpm.) |
| 3 | Motor start error
(The rotor is blocked or the differential pressure in the refrigeration system is too high (>5 bar)). |
| 2 | Fan over-current cut-out
(The fan loads the electronic unit with more than 1A peak). |
| 1 | Battery protection cut-out
(The voltage is outside the cut-out setting.) |
