Operating instructions

SEP 01.4 / SEPLC 05.2 / SEP 07.0 / SEP 09.0
EN
If plate carriers, protective caps or similar accessories are used, the
maximum admissible front plate thickness must be reduced by the plate
thickness of the accessory.
Mounting the switching elements
The element is placed onto the actuator from the rearside and snapped
onto the rearside by pressure (Fig. 3). When no accessories are used,
a maximum of two switching elements can be itted.
If three elements and one/two switching element(s) are required, the
support must be placed onto the actuator before the elements are
snapped on.
Fig. 13
Note:
For emergency stop devices equipped with 1 or 2 swit-
ching elements in combination with carrier 3SB3901-0AB, one
switching element must be mounted in central position!
5.8 Mounting instructions for the SRB 201ZH safety-monitoring
module
Mounting: snaps onto standard DIN rails to EN 60715.
Snap the bottom of the enclosure slightly tilted forwards in the DIN rail
and push up until it latches in position.
Dimensions
All measurements in mm.
Device dimensions (H/W/D):
100 (120 with plugged-in terminals) × 22.5 × 121 mm
6 Electrical connection
6.1 General information for electrical connection
Required features for the machine control
Required features for the machine control (including safety level)/
connections between the two-hand control panel and the machine
control: refer to the relevant safety, professional or product standards
(C-standards), e.g.:
• DIN EN 692 – Mechanical presses,
• prEN 693 – Hydraulic presses,
• EN 201 – Injection moulding machines for rubber and plastic,
• prEN 1010 – Printing machines and paper processing machines,
• otherwise refer to EN 954-1.
Size and type of the feed and connecting cables
• Cables only may be fed into the two-hand control panel through the
rear or the bottom.
• Cables must be equipped with water-tight cable glands with strain-
relief feature and protection against buckling.
• Connection of the protective ground wire in two-hand control panels:
to DIN EN 60204-1, every protective ground wire must be connected
individually during wiring.
• According to the harmonised standards, no protective ground wire dis-
tribution must be realised through the available ground bolt. For each
earth bolt, only one protective ground wire connection is authorised.
• If multiple protective ground wires are connected, e.g. by feeding
multiple cables into the enclosure, a commercially available earth
terminal with the required number of terminals must be installed in the
enclosure and connected to the protective ground wire connection
(one PE terminal for each protective ground wire). The cable length
for the cable connections must be suficient, in order to provide for
suficient convenience of handling during itting or possible repairs.
• Inside the enclosure, outward insulated terminals must be provided, if
the protective ground wire should be "looped through".
• Otherwise refer to EN 60204: electrical equipment of machinery
Safety distance
• For the calculation of the required safety distance between the control
elements and the hazardous area, the following formula of prEN 999
shall be applied:
S = K × T (+ C)
• S = Minimum safety distance in millimetres, measured from the ha-
zardous area to the detection point, the detection line or the protected
ield
• K = constant in mm per second = (usually) 1,600 mm/s
• T = total response time in seconds; consists of t1 and t2:
• t1 = maximum response time of the safety device between the
(physical) triggering of the perceptive element (releasing the control
element) and the time, at which the safety device has switched the
output signal to the "OFF" state (this information is provided by the
manufacturer of the "signal processing" module.
• t2 = maximum response time of the machine, i.e. the time required to
shutdown the machine or to eliminate the risk, after the transmission
of the output signal of the safety guard (this information is provided by
the machine builder).
• C = additional distance in mm, based upon the intrusion into the
hazardous area = 250 mm, however irrelevant for the Elan two-hand
control panels*.
* If the risk of intrusion of the body or body parts into the hazardous
area is prevented during the actuation of the two-hand control panel,
e.g. by adequate covering, C can be equal to 0 mm with an admissib-
le minimum distance for S = 100 mm (quote from EN 999).
6.2 Additions/notes for plastic two-hand control panels of the type
SEPK02.0...
Assembly of control elements, emergency stop command devices
and additional signalling and command devices
Only "fully insulated" command and signalling devices must be used.
Size and type of the feed and connecting cables/cable connections
Basically only plastic cable glands with suficient strain-relief for the
cable may be used.
Grounding for SEPK02.0... without stand
In case of normal wall-mounting, SEPK02.0... is fully insulated and
therefore does not require any protective ground wire connection.
Stand assembly/grounding
If the SEPK02.0... is itted onto an Elan stand of the STP..., STPSK...,
FES..., FBES... type or other versions of stands (e.g. selfmade solu-
tions), no "conducting" connections may be created inside the panel.
The grounding bolts on the ZPL-1 intermediate plate must be removed
by the user. The stand must be individually grounded by the user, if the
cable is fed through the stand tube. On request, the ZPL-1 intermediate
plate can be realised without grounding bolt in factory without additional
charges (= ZPLK-1) (default, when the panel and the stand are supplied
by Elan in itted condition). If the connecting cables are not fed through
the stand tube, the individual protective ground wire connection on the
stand can be omitted.
