General Information
The Enabling Device can have three different positions:
The positions null and panic must be cabled and controlled by the machine
logic in order to guarantee a stop category 0 or 1 according to EN 60204:2006.
Zero position
When not pressed the Enabling Device returns to the zero position
Enable position
When pressed the Enabling Device goes into the enabling position. This
condition is often associated to machine movement activation. When released it
goes back to the null position.
Panic position
When the Enabling Device is pushed all the way in it goes to the panic

2.5.1.1 Handheld terminal chemical resistance
Test 1 (Less strict)
The units under test (UUT) are placed in a closable plastic box (120 x 85 x
65 mm).
A ball of absorbent cotton appositely tinctured with solvent will be placed
above the UUT; to avoid early evaporation, a generic solid body will be put over
the ball or, in a more simply way, the closable plastic box will be closed.
After a 10 minutes wait, the eventual body and the ball of absorbent cotton
will be removed; the solvent that remains on the UUT will not be wiped off and
the box will be closed immediately afterwards for 24 hours.
The test will be performed at environmental temperature (about 20 ◦C).
Test 2 (Very strict)
The units under test (UUT) are fully and thoroughly wet by solvent, then
will be closed into a closable box (120 x 85 x 65 mm) for 24 h.
Approximately 5 ml solvent will be sprayed over the UUT. The box will be
closed and the UUT will remain in the closed box for at least 24 hours.
The test will be performed at environmental temperature (about 20 ◦C).
Touchscreen test procedure
The Touchscreen is placed into a closable plastic box (120 x 85 x 65 mm)
and a ball of absorbent cotton appositely tinctured with solvent will be placed
above it, then the box will be closed for 1 h.
The test will be performed at environmental temperature (about 20 ◦C).

Technical data
2.5.4.4.3 Parameters useful for the PL (EN ISO 13849-

Note 1
The safety devices (Emergency Stop Push-button, Enebling Device, State
Selector) on board of H3 handheld terminal are directly hardware-connected to the
output connector pins. For this reason, the numerical values shown in 2.5.4.4.1
and 2.5.4.4.2 consider the highest performances of these devices if used in the
conditions described in 2.5.4.4.3. The numerical values of MTTFd, PFHd, SFF
and DC were obtained through the assumptions shown in 2.5.4.4.3 and are related
to each safety function frequency of use. The values for the overall safety
functions of the machine depend on how the output safety signals are managed
inside the machine controller.
37
Technical data
Note 2
The Stop Push-button and Enabling Device on board of H3 are compliant
with IEC60947-5-1. Considering that and referring to paragraph D.5.3 (table D.8)
of ISO 13849-2, it is not possible to relate dangerous failures to these components
and, so, the values of b10d, MTTFd and PFHd for the Stop Push-button and
Enabling Device does not have any relevance (from a mathematical point of view:
b10d, MTTFd = infinite and PFHd = 0).
2.6 Connection box cabling scheme
The Connection Box, as shown in picture 18, is divided in two parts:
