Fridge DW Series Product Manual
Lamp (optional, g. 5.5.1)
A 12 V 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 12 V DC. A 12 V DC lamp can be used with
both the 12 V and 24 V power supply. The lamp output is a continuous output current of 0.5 A
on average.
LED (optional, g. 5.5.1)
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 ash a number of times. The number
of ashes depends on what kind of operational error was recorded. Each ash will last ¼ second.
After the actual number of ashes there will be a delay with no ashes, so that the sequence for
each error recording is repeated every 4 seconds.
No. FLASHES ERROR TYPE
5
Electronic unit thermal stop. If the cooling system has been overloaded or the ambient
temperature is too high, the control unit will overheat.
4
Insucient motor speed. If the cooling system is overloaded, the motor is no longer able
to maintain a minimum speed of 1,850 rpm
3
Motor start error. The motor is blocked or the dierential pressure of the cooling system
is too high (> 5bar).
2
Fan stop due to overcurrent. The fan has a power input from the electronic control unit
of more than 1App
1 Battery protection stop. The power voltage is outside the set disconnect value.
