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.
A
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. The
module's printed circuit board has been sealed
completely water tight to protect against
environmental influences.
3.5 Reigniter
The reigniter is also located on the backside of the refrigerator. The power module supplies the
reigniter3 with voltage. Refer to Publication Bulletin Number 599 4716-54/5 (Pages 13-14) for
detailed information about the ignition devices used.
3.6 Thermocurrent Adapter
The thermocurrent adapter is located between the igni-
tion fuse and the thermoelement coupling. The power
module controls the thermocurrent adapter. The adap-
ter serves to switch off gas operation during the chan-
ge from gas to another operating mode by interrupting
the thermocurrent to the ignition fuse.
4.0 Installation
To guarantee the orderly functioning of the AES II refrigerator, correct electrical
installation is absolutely necessary.
The 12-V connection to the battery must be a 2-pole connection.
The connection cable must be 6 mm 2 and be 10 mm 2 for greater lengths.
The D+ control input must be wired from the generator to the 12-V supply termi-
nal (cable cross-section 1 or 1.5 mm 2 , otherwise 12-V operation is not possible).
5.0 Troubleshooting
5.1 Diagnostics Mode
The AES II system has a built- in diagnostics program used to test basic system functions.
The test program offers the capability to switch the refrigerator deliberately into certain operating
states.
The following test sequences are available:
- Self-test for the display module and power module and for communication between both
components
- AC operation (230 V) test
- DC operation (12 V) test
- Ignition device test
