1.0 Model Description I.E. Refrigerator Mobil Tropicana Super-Iso with AES (Automatic Energy with Selector) with double Interior Light Door Look 2.0 AES II System Function An AES II refrigerator independently selects between the possible energy sources of 230 V, 12 V, and gas. The control electronics automatically ensure that the refrigerator is supplied from the energy source optimal at a given time. -
Page 4: Low Voltage Operation
2.3 Low Voltage Operation The so-called "low voltage gas operation" is an exception. If the electrical power supply voltage in 230-V or 12-V operation is insufficient to maintain the cooling operation, the AES switches to gas operation under certain conditions. A yellow LED displays this state. The conditions for swit- ching over to gas operation are described in Section 2.2. -

3.4 Power Module The power module (A) is located on the backside of the refrigerator. A multicore cable connects the power module and the display module. There are fuses to protect both electrical heating cartridges located in the power module. All the electrical components for controlling the various ope- rating modes are located in this module. -
Page 9: Error Analysis And Elimination
a) Preparations The AES II device must be connected to a 230-V supply line and a 12-V supply. You must con- nect a gas cylinder and open the gas supply to test the gas function. b) Test execution You must proceed as follows to arrive at diagnostics operation: 1. -

Cause 3: After the lifting magnet drops, the AES again tries to ignite and then goes to a fault after 25 seconds. Is the thermoelement on the thermocurrent adapter loose? Elimination 3: Hand-tighten the screw connection (SW 8mm). Cause 4: The thermoelectric voltage is not sufficient to keep the ignition fuse open. -
