Mermaid REFRIGERATION/FREEZER Manuale Utente
SECTION 3
(CONTROL MODULE)
A: Electronic Control Module:
The Electronic Control Module is an integral part of the Danfoss BD35/50F compressor
system. It transforms direct current power from the vessels batteries into alternating
current to run the compressor. Never attempt to run the compressor directly from the
batteries or other power source.
system. It transforms direct current power from the vessels batteries into alternating
current to run the compressor. Never attempt to run the compressor directly from the
batteries or other power source.
B: 12/24VDC, 12/24VDC & 110V w/ Auto Change-Over
A supply voltage of either 12 or 24 volts dc is required, & the Module will run from
either without any special settings or adjustments, switching to 24v mode if the voltage is
above 17v. The Mermaid unit is also available in 12/24v & 110v with Auto Change-
Over. Should this be your model, the unit will automatically detect either 110v or
12/24v. The unit will run on the stronger of the two power sources. Should 12/24v be
available and 110v is introduced (via shore power or generator) the unit with
automatically switch to this power source. If 110v is lost, the unit will wait 60 seconds
before automatically switching back to 12 or 24 volts dc.

SECTION 4
(SAFEGUARDS)
Protection from the following is provided
A: Low Voltage:
To prevent the batteries from being totally discharged, the compressor will be stopped if
the voltage at the terminals on the Module falls below 10.6 volts (23.4), & will not re-
start until the voltage rises above 11.7 (24.0) volts.

start until the voltage rises above 11.7 (24.0) volts.
B: High Voltage:
If the voltage exceeds 17v, the Module stops the compressor & switches into 24v mode,
but will not attempt to start the compressor until the voltage reaches 24v.
