Enablingswitchesandanemergencystopbutton(orhalt-button)arethesafety
elements of the device.
The Handheld Terminal is intended for fixed connection to a robot. Handheld
Terminals for temporary connection must not have a red-yellow emergency
stop button. In this case a handheld terminal with grey halt-button is available.
To meet the safety category 3 PL d in accordance with EN ISO 13849-1, the
safety functions are realized with 2 circuits.
The selection of the Handheld Terminal which is suitable for the machine and
the projecting of the additional functions must obey the necessary hazard
analyses and risk assessment bounded by law.

1.6 Definition of terms
Thisuser'smanualcorrespondstomachinery directive 2006/42/EC.Theterms
used in this manual that come from the machinery directive are the same as
in the preceding MD 98/37/EC.
Within standard EN 60204-1 the following term has changed:
EN 60204-1:1997 EN 60204-1:2006
Enabling device Enabling control device (chapter 10.9)
In order to avoid ambiguity for users this manual still uses the term of
EN 60204-1:1997.
1.7 Information about MD 2006/42/EC
Themachine directive (MD) 2006/42/EC will be valid from 2009-12-29 (without
any transition period). This means that all machines and safety components
that will be brought to market after this date have to confirm this new MD and
its harmonised standards.
For handheld terminals from KEBA this means that besides the new machine
directive also the standard EN ISO 13849-1:2008 will be used.
EN ISO 13849-1 demands for the safety relevant component "enabling switch"
the specification of category and Performance Level (PL) and for emergency
stop-buttons and grey stop-buttons the specification of the B10d-value.
These values can be found within the manuals in chapter 13.5 "E-Stop rat-
ings" on page 129 and chapter Technical data, Enabling device.

1.7.1 Which devices have to comply with the new machine directive?
This rule is valid for KEBA and its customers:
Depending on the date the product has been put into circulation the new ma-
chine directive has to be applied or not. If the KeTop will be delivered in its end
use after 2009-12-29, it will be put into circulation newly - even if it has been
sold by KEBA at an earlier date.
●Devices complying with the old MD and that will be sent to KEBA for repair,
can be repaired and delivered in compliance with the old MD.
●Customer sends old device for repair and will receive the same or another,
equal device.
●DevicescomplyingwiththenewMDandthatwillbesenttoKEBAforrepair,
must be repaired and delivered in compliance with the new MD.
1.7.2 Quantitative safety relevant specifications for emergency stop-button
and enabling control device
●Emergency stop-button:
KEBA specifies a B10d-value. Other values (e.g. SIL, PL, Category) can-
not be specified by KEBA.
Explanation: KEBA solely delivers the control element, but no evaluation
of the element. The customer has to connect the emergency stop to his
application on his own. Depending on the connection of the emergency
stop to the machine the SIL- or category and PL-value can be determined.
●Enabling control device:
KEBA specifies category and PL in accordance to EN ISO 13849-1. De-
rived from this value KEBA also specifies a PFH- and MTTFd-value in
accordance to EN ISO 13849-1. SIL (in accordance to EN 62061 or
EN 61508) cannot be specified by KEBA.
Explanation: The enabling control devices has been evaluated in accord-
ance to EN ISO 13849-1. A B10d-value is not available for the enabling
control device, as this device consists of the mechanic element and the
electronic evaluation. This means that KEBA specifies MTTFd- and DC-
values (and derived from these values also Category, PL and PFH) for the
enabling control device as a whole (starting from the pushbutton up to the
clamps within the junction box).
1.7.3 Relationship between Performance Level and Safety Integrity Level
When evaluating safety functions by IEC EN 62601 the PL can be transformed
into SIL by following the equivalence table of EN ISO 13849-1.
Table 4 (EN ISO 13849-1) - Relationship between Performance Level (PL) and
Safety Integrity Level (SIL)

2 Safety notes
2.1 Representation
At various points in this manual you will see notes and precautionary warnings
regarding possible hazards. The symbols used have the following meaning:
DANGER!
●indicates an imminently hazardous situation which will result in death or
serious bodily injury if the corresponding precautions are not taken.
WARNING!
●indicates a potentially hazardous situation which can result in death or se-
rious bodily injury if the corresponding precautions are not taken.
CAUTION!
●means that if the corresponding safety measures are not taken, a potentially
hazardous situation can occur that may result in property injury or slight
bodily injury.
CAUTION
●CAUTION used without the safety alert symbol indicates a potentially haz-
ardous situation which, if not avoided, may result in damage to property.
●This symbol reminds you of the possible consequences of touching elec-
trostatically sensitive components.
Information
Useful practical tips and information
on the use of equipment are identified by the “Information” symbol. They do
notcontain anyinformation thatwarns aboutpotentially dangerousor harmful
functions.
2.2 2.2 General safety instructions
The device was developed, manufactured, tested and documented in ac-cord-
ance with the applicable safety standards. If you follow the instructions re-
garding safety and use as described in this manual (see chapter 1.3 "Intended
Use of the Handheld Terminal" on page 11), the product will, in the normal
case, neither cause personal injury nor damage to machinery and equipment.
The instructions contained in this manual must be precisely followed in all cir-
cumstances. Failure to do so could result in the creation of potential sources
ofdangerorthedisablingofsafetyfeaturesintegratedinthehandheldterminal.

Apart from the safety instructions given in this manual, the safety precautions
andaccidentpreventionmeasuresappropriatetothesituationinquestionmust
also be observed.
Handling of KeTop
You have chosen a high-quality KeTop that is equipped with highly sensitive
state-of-the-art electronics. To avoid malfunctions or damage through improp-
er handling, follow these instructions during operation.
WARNING!
The following application areas are expressly excluded for the KeTop:
●Use in areas prone to explosion or fire
●Use in mining
●Outdoor use
Other products must be used for these applications!
The KeTop housing must not be opened (acception: cable entrance area) , as
the KeTop is sensitive to electrostatic discharge.
Safety notes

User's Manual V1.50 17

CAUTION
●Turn off the power supply before opening the cable entrance area of the
KeTop. Otherwise the components could be destroyed or undefined signals
could occur.
●Make sure that nobody can fall over the cable to avoid that the device falls
to ground.
●Take care not to squeeze and thus damage the cable with any object.
●Do not lay the cable over sharp edges to avoid damaging the cable sheath.
●If you do not use the device, hang it into the wall bracket KeTop WBxxx
provided for storage.
●Do not lay down the device with the operating side facing down to avoid
damaging the operating elements.
●Never lay the device onto unstable surfaces. It could fall to ground and thus
be damaged.
●Never lay the device close to heat sources or into direct sunlight.
●Avoid exposing the device to mechanical vibrations, excessive dust, hu-
midity or to strong magnetic fields.
●Never clean the device, operating panel and operating elements with sol-
vents, scouring agent or scrubbing sponges. For cleaning the device, use a
soft cloth and a bit of water or a mild cleaning agent.
●Make sure that no foreign objects or liquids can penetrate into the device.

3 General product description
The handheld terminal KeTop is a portable operating and display device with
rugged design and Windows-CE compatible electronics. Using a high-per-
formance processor and providing a serial interface and Ethernet, the KeTop
is ideal for a great variety of applications (see chapter 1.3 "Intended Use of
the Handheld Terminal" on page 11).
All tasks can be solved graphically and in color, and operation is intuitive using
a touch screen.
Instead of rotating mass memories such as floppy disk and hard disk drives
that are not suitable for rough environmental conditions, the KeTop uses scal-
able FLASH and RAM banks.
The KeTop provides a Windows CE platform for applications generated with
common visualization tools or with C#, Visual Basic.NET or Visual C++. More-
over, the KeTop can be connected as a client to a Win NT, Win 2000 or
Windows XP server.
Through the use of optional operating and control elements, the KeTop can
easily be adapted to the specific application.
