2SAFETY
The LP 14 meets the requirements in respect of the CE mark.
The following symbols are used in this technical manual:
Indicates: caution, risk of personal injury.
ᏘIndicates: caution, may cause damage to the machine.
☞Indicates: important information.
➭Indicates: tip.
If you are performing repairs on or making modifications to electronic components, you must
observe the safety instructions below. Neither the manufacturer nor the supplier will be held liable
for injury occurring as a result of failure to comply with these instructions.
Note
• When performing repairs on the machine, you must remove the
service key and disconnect the machine from the power supply.
ᏘWarning
• The electronic components in these machines are sensitive to
static electricity. Therefore, the maintenance engineer must always
wear an earthed wrist band when carrying out maintenance on
electronic components.
• Do not excessive amounts water when cleaning the machine.
• Comply with the applicable local regulations when connecting the
equipment to the water and electricity supplies.
☞Note
• When returning printed circuit boards to the factory for repair, they
must always be packed in anti-static packaging.
• No adjustments or modifications may be made to the machine
without written approval from ETNA Vending Technologies b.v.

4 DESCRIPTION OF PRINTED CIRCUIT BOARDS
The electronic printed circuit boards and general system specifications are described in this
chapter.
The electronic printed circuit boards consist of four printed circuits.
1. The control PCB: the main controller
(see paragraph 4.2) .
2. The power supply PCB: 24V for the control PCB
(see paragraph 4.3) .
3. The display PCB: includes the user interface (see paragraph 4.4) .
4. The output PCB: the output relay
(see paragraph 4.5) .
4.1 General specifications
The general specifications of the LP 14 are shown in table 4-1 .
Table 4-1 General specification of the LP 14
4.2 Control PCB
The control PCB is the most important electronic component. It has ten connectors. The function
of each connector is described in the following paragraphs.
All connectors have a unique code. The coding system for the control PCB connectors is Con x,
where "Con" stands for connector and "x" is a unique number.
Figure 4-1 shows layout of the control PCB.
