Notes:
•
Safety device 1 (robot) and the auxiliary safety device for the robot position are permanently muted (allowing the robot to
enter the hazardous area):
1.
If safety device 2 (operator) is not activated
OR
2.
If safety device 2 has been activated, but the operator has pushed the acknowledge push-button, to confirm that he has
left the hazardous area.
•
The start push-button must be pushed AND released within 3 s, to energise the safety output contact of the module.
•
The acknowledge push-button must be pushed for acknowlegment during less than 3 s.The module de-energises its safety
output contacts, when the push-button is pushed longer than 3 s.
•
Pushing the start push-button with one or both of the robot’s safety devices activated leads to the energisation of the module
output contacts:
1.
If safety device 2 (operator) is not activated
OR
2.
If safety device 2 has been activated, but the operator has pushed the acknowledge push-button, to confirm that he has
left the hazardous area.
TEMPORARY MANUAL MUTING (TMM)
An external temporary manual muting may be necessary, in order to evacuate an object (e.g. a palette with goods in a conveyor
application) accidentally remaining in the detection field of a safety device.
The use of a TMM may be necessary in the following cases:
•
An object remains in the detection field of a safety device.
•
The selected maximum muting time has elapsed.
•
Loss of power.
•
An application error or a fatal error occurred on the module (e.g. muting lamp failure).
The external TMM system shall be composed by the following components (customer supplied):
•
One dual contact key selector switch with two positions or two separate key selector switches with two positions (alternative:
two-hand control).
•
Two external safety contactors (with mechanically guided contacts and a normally closed EDM monitoring contact).
•
The muting lamp (already connected to terminal 48 of the module).
