Safety precautions
Ì
All system components must be mounted on surfaces that can reliably withstand all the forces that may occur.
Ì
Routing the rope as straight as possible results in low frictional forces in the system. From a system length of 25 m,
only rope pulley blocks may be used as rope supports. Rope pulley blocks and other accessories are optionally avail-
able.
Ì
Positioning the support points at irregular intervals prevents rope oscillations that might cause false tripping.
Ì
The red pull rope must have sufficient space between the support points to ensure that secure gripping and activation
are possible. To improve visibility, marking flags can be attached to the pull rope along its length; however, these must
not interfere with activation of the emergency stop function!
Ì
When a rope pull section is being set up and planned, it is necessary to take into account and comply with the applica-
ble regulations, as well as the maximum permitted actuating travel of S = 400 mm and maximum tripping force of F =
200 N applied perpendicularly to the rope.
Ì
Suitable guide rollers (roller diameter ≥ 50 mm) must be used for rope routing at angles. The rope pull section must be
angled by no more than 180° (e.g. 2 x 90°).
Ì
Improper installation of or tampering with the rope pull switch will lead to loss of the personnel protection function and
can cause serious or fatal injuries.
Ì
Rope pull switches must not be bypassed (bridging of contacts), turned away, removed or otherwise rendered ineffec-
tive.
Ì
Mounting, electrical connection and setup only by authorized personnel.
Ì
If damage or wear is found, the complete switch must be replaced. Replacement of individual parts or assemblies is not
permitted!
Ì
The user is responsible for safe integration of the device into a safe overall system. For this purpose, the overall system
must be validated, e.g. in accordance with EN ISO 13849-2.
Ì
If the simplified method according to section 6.3 of EN ISO 13849 1:2015 is used for validation, the Performance Level
(PL) might be reduced if several devices are connected in series.
Ì
If a product data sheet is included with the product, the information on the data sheet applies in case of discrepancies
with the operating instructions.
