TECHNICAL INFORMATION
Tanning appliance HB 953 is equipped with a universal power PCB.
This means that the specifi c characteristics of the appliance have to be programmed in a microcontroller to determine the way in which various components are activated.
When the mains plug is inserted into the wall socket, the display of the remote control will show all functions available to the user.
Including the various combinations, these functions are:
time setting full body tanning full body + facial tanning half body + facial tanning half body tanning UV working hours
The UV lamps may produce a humming sound just after start-up. This humming sound will stop as soon as the lamps burn properly, which is after about 20 seconds. At this point the light intensity clearly increases.
During the last minute of the session the beeper produces an intermittent signal to alert the user to the fact that a new session can be set.
After pressing the
key, the display showing and , the UV working hours will be shown. After 750 operating hours, an L will automatically appear on the display to indicate that the HPA lamps need to be replaced or the tanning time must be slightly increased.
The clock speed of the µ-controller is derived from the 50 Hz mains frequency.
This frequency is also used to control the 8 triacs that determine the switch-in point (soft start) of the cos ϕ capacitors and the HPA lamps.
The fans are switched via the safety relay. This relay is part of the (one fault condition) timer circuit. If the control of the triacs is disturbed due to a fault in the
µ-controller, the UV lamps may not be switched off. As the µ-controller also generates a pulsating direct voltage
to power the relay, the relay will be de-energised in case of a fault, thereby interrupting the lamp circuit.
Conversely, the appliance will not start if the switch contacts of the relay are closed at that moment (sticking contacts).
The remote control is galvanically isolated from the mains, with power supply and control taking place via a 4-core cable.
The remote control only functions as input/output terminal.
HINTS FOR REPAIRS
1. FLOOR PART (item 47)
- Remove the props (item 43) in the grip.
- Remove the covers (item 32 and 44). The cover on the fl ex side can only be removed last.
2. REMOTE CONTROL (item 30)
- Detach the cord clamp at the back of the cord holder and pull the connector loose.
3. WHEEL (item 35)
- Remove the covers (item 32,44).
- Remove the locking plate and the nearest frame screw.
- Push the shaft out of its clamping.
4. STAND LOWER PART (item 27)
- Put the appliance in the lowest operating position (however, screw (A) must be visible) and tighten the ornamental screw (item 26)
- Remove the covers from the fl oor part.
- Detach the 8-core cable so that the cable can easily slide through the cable duct.
- Remove the shafts (B).
- Remove the 2 bearing bushes (item 28).
- Pull the 8-core cable out of the stand tube to the point where the clamped joint between the cable bushing and the protecting sleeve can be unlocked.
- Detach the 8-core cable by loosening the nut of the bushing a quarter turn.
- Now turn the stand and the radiation units through so far that the covers (item 14/16) rest on the fl oor.
- Remove screws (A) and separate the upper and lower part of the stand.
5. STAND UPPER PART (item 22)
- Loosen the lower part of the stand as described under .4.
- Hinge the radiation units outwards (the upper part of the stand rests on the fl oor).
- Remove the housing parts and detach the wire connections.
- The covers (item 14/16) can now be separated from the hinge part. WHEN A HOUSING AND COVER ARE ASSEMBLED, SPECIAL ATTENTION SHOULD BE PAID TO THE POSITIONING OF THE UPPER BEARING BUSH (see exploded view).
6. HPA LAMP (item 6)
- Put the appliance in operating position.
- Remove the 6 screws from the lamp unit in question.
- Remove the cover (item 14 or 16).
- Remove 4 refl ector clamps.
- Remove the refl ector and take the lamp from the holder.
NB: When checking or replacing HPA lamps, pay
attention to the following:
a. HPA lamps only start burning when they have cooled
down suffi ciently.
b. Never touch a lamp with your fi ngers. Clean the lamp
with a cloth moistened with alcohol, if necessary.
c. After assembly the glass fi lter should be free from
fi nger prints and dust. Clean the glass fi lter with a cloth moistened with alcohol, if necessary.
d. New HPA lamps may show colour differences. This
is not a defect, but a characteristic phenomenon of lamps of this type. The discolourations disappear after a short period of use.
e. Always use protecting goggles when looking in the
direction of burning lamps.
7. GAS SPRING (item 17)
- Let the radiation part slowly rise from its transport position.
- Hinge the radiation units outwards and remove a decorative cap and spring fi x at C.
- Now push the radiation part back into transport position.
- Use a plastic hammer to tap the pin at C outwards.
NB: CONTINUE TO EXERT PRESSURE ON THE
STAND.
- Hinge the radiation units inwards again and raise the stand slowly by means of the handle.
- Now turn the stand and the radiation part through so far that the radiation units rest on the fl oor.
- The gas spring is now unloaded so that pin (D) can be easily removed.
- Assemble the new gas spring, the protecting bracket and cover and press the pin (D) back in place again.
- Lift the radiation part by its handle and check whether the gas spring with pin (E) is correctly supported in the fork of the hinged part.
- Press the hinged part against the spring pressure, moving the radiation part along at the same time until the whole unit is in horizontal position again.
- Continue to exert pressure and hinge the radiation units outwards.
- Assemble the pin at C.
- Put the appliance in operating position, and assemble the remaining clamps.
8. POWER PCB (item 33)
- Pull the mains plug out of the wall socket.
- Remove the cover (item 32, see under .1).
- Replace the power PCB and connect all connectors.
- Place the cover on the base. The display of the remote control will now show error code E06 or E05.
- This indicates that the power PCB still needs to be programmed (code A03) for use in the HB 953 according to the input in the table.
The following fault codes have been defi ned:
E01 - Safety circuit interrupted
This code will appear on the display for 5 seconds, while the beeper produces a loud beep. Check whether all fans work or whether any UV fi lter is missing, broken or damaged.
E02 - Safety relay does nor work according to
specifi cation
Replace the power module (item 33).
E03 / Fault in microprocessor E04 - Replace the power module (item 33).
E05 / Application code not programmed E06 - This only occurs in case of a new power
module supplied by Service. Program the application code, beginning at line 1, step 3.
