Data Sheet Guardian Line Series
Using Safety Rope Emergency Stop Switches
Application:
Safety Rope Emergency Stop Switches are mounted on machines and sections of plant conveyors which cannot be protected by guards. In contrast to traditional
mushroom head type Emergency Stop buttons, Safety Rope Switches can initiate the emergency command from any point along the installed rope length.
In combination with any dual channel safety monitoring controllers IDEM Safety Rope Systems can be used as emergency stop devices and monitored for up to
Category Le/Cat.4 to ISO13849-1. It is the responsibility of the user to ensure the correct overall functionality of its systems and machines. IDEM, its subsidiaries and
affiliates, are not in a position to guarantee all of the characteristics of a given system or product not designed by IDEM.
peration:
All IDEM Safety Rope Emergency Stop Switches conform to Standards ISO13850 and IEC60947-5-5. They have a positive mechanical linkage between the switch contacts
and the wire rope as per IEC60947-5-1. The emergency stop switches are brought into the operational condition by pre-tensioning the rope by use of a tensioner/gripper
device which clamps the rope and then hooks to the switch eyebolts. Correct tension can be observed by viewing the tension indicator on the switch housing. Once
tensioned the switch contact blocks can be set to the operational condition (safety contacts closed, auxiliary contacts open) by pressing a blue reset button on the switch
cover.
All of the Safety Rope Switches have wire-breakage monitoring. On pulling or breakage (tension loss) of the rope, the safety contacts are positively opened and the auxiliary
contacts are closed. The switches are mechanically latched and can then only be returned to the operating condition by pressing the reset button as required by ISO13850.
Installation Guide:
1. Installation of all IDEM Safety Rope Switch systems must be in accordance with a risk assessment for the individual application. Installation must only be carried out by
competent personnel and in accordance with these instructions.
2. According to ISO13850 pulleys may only be mounted such that a complete length of the rope can be observed.
3. Rope support eyebolts must be fitted at 2.5 m. min. to 3m. max. intervals along all rope lengths between switches. The rope must be supported no more than 500mm
from the Switch eyebolt or Safety Spring (if used). It is important that this first 500mm is not used as part of the active protection coverage.
4. M5 mounting bolts must be used to fix the switches. Tightening torque for mounting bolts to ensure reliable fixing is 4 Nm. Tightening torque for the lid screws, conduit
entry plugs and cable glands must be 1.5 Nm to ensure I seal. Only use the correct size gland for the conduit entry and cable outside diameter.
5. Tensioning of rope is achieved by use of IDEM tensioner/gripper assemblies.
On installation set the tension to the mid position as indicated by the markers in the viewing window of each switch. Check operation of all switches and the control circuits
by pulling the rope at various locations along the active protection area and resetting each switch by depressing the Blue Reset button. Ensure each time that the switches
latch off and require manual resetting by depressing the blue reset button. Increase the system tension further, if required, depending upon the checks along the active
length of coverage.
If fitted with a Mushroom type E-Stop button (Red) then test and reset each switch to ensure correct function of the safety control circuits.
Typical operational condition for successful operation of the system is less than 75N. pulling force and less than 150mm deflection of rope between eyebolt supports.
6. Maintenance:
Every Month: Check correct operation of system at locations along all coverage length. Check for nominal tension setting, re-tension rope if necessary.
Every 6 Months: Isolate power and remove cover. Check screw terminal tightness and check for signs of moisture ingress. Never attempt to repair any switch.
