5 Mounting
5.1 Mounting instructions for two-hand control panels
Required space
for e.g. installation, checking, maintenance, etc.: refer to the supply ta-
bles according to the Elan list ZHS/08 (maintenance of the components
is not required).
Fixing
Non-portable two-hand control panels:
• Individual panels: rearside (with mounting holes) horizontally
• Panels with stands: loor mounting (with mounting holes for loor
mounting)
• Control elements: at least 830 mm over the access area
• When a rotating mechanism is used, the lower safety distance in no
way must be exceeded.
• The panels must be ixed so that they cannot be removed by simple
means.
Portable two-hand controls:
• Authorised for the versions STP01.4..., STP01.5..., STP02.4...,
STPSK..., FES01.4..., FBES01.4... and FBES02.4...
• In two-hand control panels with plug-in cables, no emergency stop
command devices must be integrated to DIN EN 692 and
DIN EN 693.
• According to SUVA (CH), a lateral protection must be additionally
provided at the outer covers of movable panels if necessary, if the
required approach speeds cannot be observed. If the possibility
exists that the operator can access the press chamber or similar with
the movable panel, this situation must be prevented by means of an
accordingly determined access cable length or by a suitable spacer at
the stand or similar mechanical features.
• A relocation of the operating unit (two-hand control panel and stand)
up to the hazardous point or area must be limited by the user. This
can be realised for instance by means of a suitable spacer, which is
welded to the stand (refer to DIN EN 574).
Identiication plate
• The identiication plate does not include all speciications mentioned
sub n° 11 of DIN EN 574. Speciications regarding the type and the re-
sponse time generally must be made by the user, as these speciica-
tions generally cannot be realised upon the delivery of a stand-alone
two-hand control panel (i.e. without the corresponding circuit).
• When mechanical pushbuttons with a max. diameter of 55 mm are
itted, the two-hand control panels meet the requirements of
DIN EN 574 regarding tampering by hand, elbows and legs.
Plastic two-hand control panels type SEPK02.0...
Plastic two-hand control panels of the type SEPK02.0... are suitable for
temperature ranges from –25 to +60°C. At temperatures < –5/–10°C
a speciic reduction of the shock resistance of the material must be
observed. If temperatures of > +60°C can be expected in hot areas, the
use of metal two-hand control panels (refer to List ZHS/08) is recom-
mended.
5.2 General mounting instructions for control elements
• Control elements must be selected, designed and installed so that
they can provide for an ergonomical operation.
• For ergonomical reasons, the actuating surface of a control element
/ pushbutton should have a diameter of at least 40 mm and for safety
reasons of 55 mm at the most.
• Control elements must not be red and must not build crushing or
shearing points with their environment.
• Foreseeable forces, triggered by the acceleration of a two-hand
control panel, must not generate an output signal (e.g. by falling,
unexpected shock, impact load, etc.)
• According to EN 574, the switching elements of type III C control
elements must have a "1 NC/1 NO" contact coniguration. It is recom-
mended to realise the NC and NO contacts in two switching elements,
which are independent from each other, for each control element/
signal converter. As the occuring actuating forces are regarded, it
furthermore is recommended to equip the individual control elements
with max. two switching elements.
• • Other particularities: see Elan List ZHS/08.
