Fig.13: Door and covers

To prevent injuries, there are one door and

various safety covers attached to the

SIPLACE JTF‑ML2.

The door(1) on the SIPLACE JTF‑ML2 is

locked during operation.

When the cassettes need to be changed,

the door can be unlocked using the station

software. The SIPLACE JTF-ML2 is inactive

then and all motors are stopped.

 WARNING!

Door

It is not allowed to operate the

SIPLACE JTF‑ML2 without or with

open door.

The SIPLACE JTF-ML2 has several covers.

Do not remove these.

(3) Back and top cover

 WARNING!

Covers

It is not allowed to operate the

SIPLACE JTF-ML2 without covers.

Safety protective switch and actuator (1)

This switch is to monitor safety loop signal

from TX machine and detect opening of the

door. If either signal is opened, door switch

contact will be opened and de-energized

safety relay output. Power supply to all mo-

tors will be cut-off.

2.4 ESD guidelines

2.4.1 What does ESD mean?

Fig.15: ESD label

Almost all of the modules in use today are equipped with highly integ-

rated Metal-Oxide-Semiconductor (MOS) blocks and components.

The manufacturing techniques used mean that these electronic com-

ponents are extremely sensitive to overvoltage and thus to electro-

static discharge.

The abbreviation for such modules is "ESD" (Electrostatic Sensitive

Device). "ESD" is used internationally. The following symbol on cab-

inet rating plates, racks or packaging indicates that components

which are sensitive to electrostatic discharge have been used and

thus that the modules concerned are also touch-sensitive.

ESDs can be destroyed by voltages and power levels that are far below the level that can be per-

ceived by humans. Such voltages occur if a person touches a component or module without

earthing themselves. Components that are exposed to such overvoltages do not generally appear

to be defective immediately - incorrect behavior starts after the component or module has been in

operation for some time.

2.4.2 Important measures to protect against static charging

► Most plastics can easily become charged and must therefore be kept away from at-risk com-

ponents.

► Always ensure that people, the workplace and packaging are safely earthed when handling

electrostatic sensitive components.

2.4.3 Handling ESD modules

As a general rule: Only touch electronic modules if you must carry out work on the modules. In that

case, make sure that you do not touch the pins or printed conductors when you pick up flat mod-

ules.

Only touch components if you are earthed by one of the following measures:

●

You are wearing an ESD wristband.

●

You are wearing ESD shoes.

●

You are wearing ESD shoe earthing strips on an ESD floor.

Immediately before you touch an electronic module, discharge your own body by touching a con-

ductive and earthed object (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 move the assemblies near to data view devices, monitors or television units. Keep a min-

imum distance of 10 cm to monitors.

2.4.4 Measurements and modifications to ESD modules

Only perform measurements on modules if one of the following conditions is fulfilled:

●

You are using an earthed measuring device (e.g. via PE conductors)

●

You are using a potential-free measuring device and discharge the measuring head before

the measurement (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.

2.4.5 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 pack-

aging. 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.

2.5.1 FCC Caution

Any changes or modifications not expressly approved by the party responsible for compliance

could void the user's authority to operate this equipment. This device complies with Part 15 of the

FCC Rules. Operation is subject to the following two conditions:

1. This device may not cause harmful interference, and

2. This device must accept any interference received, including interference that may cause

undesired operation.

NOTICE

This equipment has been tested and found to comply with the limits for a Class B digital

device, pursuant to part 15 of the FCC Rules. These limits are designed to provide

reasonable protection against harmful interference in a residential installation. This

equipment generates, uses and can radiate radio frequency energy and, if not installed and

used in accordance with the instructions, may cause harmful interference to radio

communications. However, there is no guarantee that interference will not occur in a

particular installation. If this equipment does cause harmful interference to radio or

television reception, which can be determined by turning the equipment off and on, the user

is encouraged to try to correct the interference by one or more of the following measures:

► Reorient or relocate the receiving antenna.

► Increase the separation between the equipment and receiver.

► Connect the equipment into an outlet on a circuit different from that to which the recei-

ver is connected.

► Consult the dealer or an experienced radio/TV technician for help.
