– The axis unit receives a "servo enable" signal for the servo amplifier
– 48 V for X tables (34 V for S tables, not for X4I) – operating voltage is switched through to
component trolleys
– 24 VDC operating voltage is switched to the used tape cutters.
– The PCB conveyor control receives the enable signal for the PCB clamping, the PCB stopper
and the lifting table control.
The machine is then ready for use.

Handling ESD Mod ules
2.5.1 Handling ESD Modules
Do not touch electronic modules unless it is absolutely essential to do so in order to carry out other work.
If it is necessary, make sure that you do not touch the pins or printed conductors when you pick up flat
modules.

ESD Guidelines Measurements and Modifications to ESD Modules

Do not touch components unless
▪ you are constantly earthed by an ESD wrist strap or
▪ you are wearing ESD shoes or ESD shoe earthing strips on an ESD floor.
Always discharge yourself before you touch an electronic module. To do this, simply touch a conductive
and earthed object immediately before you touch the module (such as unpainted parts of a switch
cabinet, a water pipe, etc.).
Do not allow modules with chargeable and highly insulating materials to touch one another, e.g. plastic
films, insulating table surfaces or items of clothing made from synthetic fibers.
Always place the modules on a conductive surface (table with an ESD coating, conductive ESD foam,
ESD bag or container).
Do not bring modules near visual display units, monitors or televisions. Keep them at least 10 cm away
from the screen.
Measurements and Modifications to ESD Modules
2.5.2 Measurements and Modifications to ESD Modules
Do not take measurements on such modules unless
▪ the measuring device is earthed (e.g. via PE conductors) or
▪ you discharge the measuring head just before taking measurements with a potential-free measuring
device (e.g. by touching an unpainted metal part of the controller casing).
► Always use an earthed soldering iron if you carry out any soldering work.
Dispatching ESD Modules
2.5.3 Dispatching ESD Modules
► Always store modules and components in conductive packaging (e.g. metallized plastic bags or
metal sleeves) and dispatch them in conductive packaging.
► If the packaging is not conductive, place the modules in a conductive envelope before packaging.
Use conductive expanded rubber, ESD bags, domestic aluminum foil or paper, for example. NEVER
use plastic bags or film.
► If the module has integral batteries, ensure that the conductive packaging does not touch or short-
circuit the battery terminals and, if necessary, first cover the terminals with insulating tape or
material.
