ENGLISH

The electronic unit is a multi voltage device. It can be used in both 12V/24V DC and 100-240V AC 50/60Hz power supply systems. Max. voltage is 17V DC for a 12V DC system and 31.5V DC for a 24V DC power supply system. Max. voltage is 265VAC and min. 85VAC for anAC power supply system. Max. ambient temperature is 55°C. The electronic unit has a built-in thermal protection which is actuated and stops the compressor operation if the electronic unit temperature becomes too high (100°C / 212°F on the PCB). Power consumption is limited to 100W. See datasheet BD50F for details.

Installation (Fig. 1)

Connect the terminal plug from the electronic unit to the compressor terminal. Mount the electronic unit on the compressor by snapping the cover over the screw head (1).

Power supply (Fig. 1)

DC: The electronic unit must always be connected directly to the battery poles (2). Connect the plus to + and the minus to -, otherwise the electronic unit will not work. The electronic unit is protected 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. It is recommended to use 15A fuses for 12V and 7.5A fuses for 24V circuits. If a main switch (4) is used, it should be rated to a 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.

AC: The wires must be connected to the terminal marked L and N on the electronic unit. Nominal voltages from 100 to 240 VAC 50/60Hz. Upper safety cut-out limit = 270V AC and lower limit 80V AC. A 4A fuse (11) must be mounted in the live

(L) cable to protect the installation.

If a main switch (12) is used, it should be rated to a current of min. 6A. The wire dimensions must be min. 0.75 mm2 or AWG 18.

NB: Earth connection can be used if required.

General: Both the AC and the DC power supply can be connected to the electronic unit at the same time. In this case,AC will be preferred power supply source. If the AC power supply is disconnected or drop below 85VAC on a 12V DC supply system, a time delay of 1 min. will be activated before the compressor continues on DC power supply. If AC power supply is re-established there will be no delay in compressor operation.

Battery protection (Fig. 1)

The compressor stops and restarts again according to the designated voltage limits measured on the + and - terminals of the electronic unit.

The standard settings for 12V and 24V power supply systems appear from Fig. 3.

Other settings are optional if a connection which includes a resistor (9) is established between terminals C and P. See manual.

Thermostat (Fig. 1)

The thermostat (7) is connected between the terminals C and T. Without any resistor in the control circuit, the compressor will run with a ﬁ xed speed of 2,000 rpm when the thermostat is switched on. Other ﬁ xed compressor speeds in the range between 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)

Afan (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 continuous current of 0.5Aavg. A higher current draw is allowed for 2 seconds during start.

Lamp (optional, Fig. 1)

A 12V DC 5 Watt lamp (10) can be connected between the terminals A and C. The output voltage between the terminals A and C is always regulated to 12V DC. A 12V DC lamp must be used for both 12V and 24V power supply systems.The lamp output can supply a continuous current of 0.5Aavg.

LED (optional, Fig. 1)

A 10mA light emitting diode (LED) (6) can be connected between the terminals + and D. If the electronic unit records an operational error, the diode will ﬂ ash a number of 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	Error type
	of	Error type
	of
	ﬂ ashes

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 minimum speed
	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 1Apeak).

1	Battery protection cut-out
	(The voltage is outside the cut-out setting).
