Safety Interlock Switch
Application:
IDIS-1 Tongue (Key) Interlock Switches are designed to be mounted for interlock position sensing of hinged moving guards.
They can be fitted to the leading edge of sliding, hinged or lift off guards.
They have positive opening contacts in accordance with IEC 60947-5-1 and the switch design offers a tamper resistant actuator key. They are available with either an angled or
flat actuator fixing to cover most fixing positions and contact blocks are available in slow make/break 2NC 1NO, 3NC or 1NC 1NO snap action.
Enclosures are protected to IP67.
Operation:
Operation of the switches is achieved by withdrawing the actuator key from the switch to cause deflection of the switch plunger.
Positive actuation of the contacts is achieved at 5mm withdrawal of the actuator.
Installation guide:
Correct Mounting of Interlock Switches is critical to obtain optimum performance and ensure safety reliability.
Installation of all switches 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.
Warning: Do not defeat, bypass or tamper with this switch, severe injury may result.
1.
Never use the switch as a mechanical stop.
2.
To ensure that the actuator and switch are protected from mechanical shock, guides and stops must be used to prevent mechanical damage.
3.
The heads of the switch can be rotated to obtain the best switch orientation by removing the 4 head screws and rotating the head through 90 degrees. Always ensure the
4 head screws are tightened to 1Nm to ensure switch robustness. Always fit the blanking plug (supplied) to the unused actuator entry aperture.
4.
When mounting to the guard door align and fix the switch body and actuator using 2 x M4 mounting bolts tightened at 1.5Nm.
