Read and understand these instructions before installing, operating, or maintaining this equipment.
The product is designed to be a component o a customised sa ety orientated control system. It is the responsibility o each manu acturer to ensure the correct overall unctionality o its
systems and machines. IDEM, its subsidiaries and a iliates, are not in a position to guarantee all o the characteristics o a given system or product not designed by IDEM.
Application:
Emergency Stop Switches are mounted on machines and sections o plant conveyors that cannot be protected by guards.
In combination with any dual channel sa ety monitoring controllers these switches can be used as emergency stop devices and monitored or up to Category 4/PLe to ISO13849-1.
Operation:
All Emergency Stop Switches con orm to European Standard EN ISO 13850 and IEC 60947-5-5. They have a positive mechanical linkage between the switch contacts and the
E-Stop Button. The switches are mechanically latched and can then only be returned to the operational condition by a pressing the reset button as required by EN ISO 13850
and IEC 60947-5-5.
nstallation Guide:
1. Installation o all switches must be in accordance with a risk assessment or the individual application and in accordance with local wiring regulations and EN60204-1.
Installation must only be carried out by competent personnel and in accordance with these instructions.
2. M4 mounting bolts must be used to ix the switches. Tightening torque or mounting bolts to ensure reliable ixing is 4 Nm. Tightening torque or the lid screws, conduit entry plugs and
cable glands must be 1.5 Nm to ensure IP seal. Only use the correct size gland or the conduit entry and cable outside diameter.
3. Check operation o all switches and the control circuits by activating the switch (depress the Red Button) and resetting each switch by twisting the Red Button. Ensure each time that
the switches latch o and require manual resetting.
4. For versions with the Protection Shroud ensure that the padlock size is suitable to prevent re-setting o the button.
Maintenance:
Every Week: Check correct operation o the control circuits and latching mechanism.
Inspect or damage to the E Stop button or casing.
Every 6 Months: Isolate power and remove cover. Check screw terminal tightness and
check or signs o moisture ingress. Never attempt to repair any switch.
