1.3 DESCRIPTION OF THE ELECTRIC SYSTEM
The wiring diagram SE211/06 of Star 55 2001 is visible in the section 5.1: refer to this
diagram during the following descriptions.
The electrical wiring (e.w.) of Star 55 2001 can be divided into the following parts:
- e.w. condensing group;
- e.w. evaporating group;
- e.w. inner lights;
- e.w. display light
- e.w. heated door;
- e.w. controls front panel;
- e.w. devices rear support.
The e.w. condensing group is located in the compressor opening and gives the electrical
supply to the compressor (CO) (12) and its components, to the condenser motor fan (MC)
(38), to the door isolation transformer (TI) (82), to the low pressure pressostat (PBP) (88)
and to the cut-off valve solenoid coil (VM) (2).
The power supply cord with plug (CS) (10) is directly wired to the strain relief terminal
connector (37) and to the main relay (RG) (63) on a metal support plate located on the left
side of the compressor opening: in the fig. 18c is shown this support plate and the strain
relief "2", together with the main relay "1" (RG) (63).
The e.w. evaporating group is located in the top part of the inner tank, protected by the
evaporator plastic cover (8), and gives the electrical supply to the evaporator motor fan
(MI) (39), to the end of defrosting thermostat (KFS) (5) and to the evaporator heater (REV)
(66).The e.w. inner lights gives the supply to the 2 36W inner lights (L2) (34) by means of
two electromagnetic ballast (AT2) (60) and two starters (S2) (73) located in the rear
support. The two starters are fixed in place by means of two starter holders (52).
The e.w. display light gives the supply to the 13W display lamp (L1) (33) by means of one
electromagnetic ballast (AT1) (59) located in the rear support and one starter (S1) (73)
located behind the display lamp and fixed in place by means of one starter holder (52).
The e.w. heated door gives the supply to the door frame heater (RT) (64) and the heated
glass surface (RV) by means of the isolation transformer (TI) (82), located in the
compressor opening.
The e.w. controls front panel gives the supply to the controls located on the front panel
(18), that are: the thermostat (TC) (80), the main switch (IG) (31), the lamps switch (IL)
(32) and the defrosting light (LS), located inside the lamps switch.
The e.w. devices rear support gives the supply to the electrical devices located in the back
of the cabinet (see fig. 18b) and is made by: one defrosting relay "3" (RS) (61), one
compressor relay "1" (RC) (62), one ballast (AT1) (59) for display light "5", two ballasts for
inner lights (AT2) (60) "6", one defrosting timer "7" (TS) (81), one terminal junction board
"8", one EMC filter "9" (FRF) (22) and 2 starters (S2) (73) for inner lights.
1.3.1 SYSTEM POWER SUPPLY
A power supply cord, equipped with a 15-Ampere plug, allows to connect the refrigerator
to the power supply local net.
A main switch (IG) (31), positioned on the front control panel, enables to energize all
electrical components of the refrigerator by means of the main relay (RG) (63): its green light
indicates that the system is powered.
For compliance with the directive on electromagnetic compatibility (EMC) a capacity filter
(FRF) (22) is supplied.
