Installation & Maintenance
Principle
The UGB-NET switch is mounted to the fixed frame of the guard or machine, the handle and actuator are
fitted to the moving guard with the actuator tongue aligned to the aperture of the switch head. The
mechanical tongue actuator profile is designed to match a cam mechanism within the switch head, the
cam and tongue together realise the specified holding force.
WARNING
DO NOT DEFEAT, TAMPER, OR BYPASS THE SAFETY FUNCTION.
FAILURE TO DO SO CAN RESULT IN DEATH OR SERIOUS INJURY.
NE PAS DESACTIVER, MODIFIER, RETIRER, OU CONTOURNER CETI, INTERVERROUILLAGE
IL PEUT EN RESULTER DES BLESSURES GRAVES DU PERSONNEL UTILISATEUR.
•
Observe the county-specific regulations when installing the device.
•
Repair or modification of the UGB-NET is not allowed unless authorised by IDEM
and carried out according to operating guidelines.
•
Safety critical failures which do not lead to the safe state shall be reported to IDEM
immediately.
•
Replace a malfunctioning UGB-NET immediately.
IMPORTANT
•
Ensure that the static forces applied during normal operation do not exceed the
holding force (Fzh).
•
Ensure that dynamic forces acting on the switch caused by bouncing of the guard do
not create an impact reaction force which exceeds the holding force (Fzh).
NOTES REGARDING
:
•
Maximum Temperature 40°C
Fastening
IMPORTANT
•
If fitting rotary or sliding handles ensure the M6 mounting bolts are used to fix the
appropriate mounting plates.
•
The tightening torque to ensure reliable fixing is 4.0Nm.
•
The front and rear rotary handles can be adjusted for desired position by loosening
the locking bolt which fixes the handle to the switch body.
Maintenance Activities
IMPORTANT
•
To achieve the target safety level, it is required to routinely check the safety
functions are operating correctly. For applications targeting PLe a check should take
place once per month, for PLd applications a check should take place once per year.
•
If any part of the UGB-NET displays mechanical damage then remove and replace.
•
IDEM will not accept responsibility for failure of the switch functions if the
installation and maintenance requirements shown in this document are not
implemented.
