Installation

Installation of the Elf™ and Cadet™ 3 Tongue Interlock Switches must be in accordance with the following steps and stated specifications and should be carried out by suitably competent personnel. The unit is not to be used as a mechanical stop. Guard stops and guides must be mounted.
Adherence to the recommended maintenance instructions forms part of the warranty.
ATTENTION: The presence of spare actuators can compromise the integrity of the safety systems. Personal injury or death, property damage or economic loss can result. Appropriate management controls, working procedures, and alternative protective measures should be introduced to control their use and availability.

Maintenance

Every week, check the alignment of the actuator to the switch and the correct operation of the switching circuit. Also check for signs of abuse or interference. Inspect the switch casing and actuator for damage. Replace if needed.
At least every six months, isolate all power. Remove the lid and end cover. Inspect all terminals for tightness. Clean out any accumulation of fine dirt. Check for any sign of wear of damage, for instance, actuator wear, cam assembly wear, contact oxidization and replace if needed. Replace cover and tighten screws to specified settings. Reinstate the power and check for correct operation. Reapply tamper evident varnish or similar compound for mountings.
WAR N IN G : Do not defeat, tamper, remove, or bypass this unit. Severe injury to personnel could result.
