Emergency Stop Input
To use the emergency stop switches externally, input two (2) b-contacts
interconnected from the SAFE connector (between 2-3 and 5-6) on the controller
front panel. If either of these signals is in open status, emergency stop status cannot
be canceled. To restore from emergency stop status, place all connected
emergency stop switches in close status. The controller enters servo ON enabled
status without error indication by placing RST-1 and RST-2 in the same connector in
short-circuited status (150 ms (min.)).
Independent dual-redundant c-contact outputs are provided to indicate controller
status. Use these if the high-order sequencer is available and for the LED indicating
the controller status.
Relay output contact specification:
Maximum rating: 250 VAC, 6 A (max.)/125 VDC, 6 A (max.)
Notes on selection and placement of emergency stop switches
Note on the following when choosing and locating an emergency stop switch:
- Install an emergency stop device to the TSL3000E/TSL3100E and other locations
where emergency stop is required. All the emergency stop devices must be
placed where they can be easily accessed.
- Choose an emergency stop device which has such a structure that when the
emergency stop device works, the circuit will not be automatically reset until the
emergency stop device is reset manually and the contact will be reset only after
the emergency stop device is reset.
- Choose any of the following shapes of emergency stop device that is suitable for
the machine structure and characteristics so that unsafe conditions can be
eliminated:
1) Mushroom-type pushbutton
2) Rope pull type, or bar type
3) Belly or knee action type
4) Pedal switch without a protective cover
- The pushbutton type of emergency stop device shall have a red actuator on a
yellow background.
- The rope pull type of emergency stop device shall always maintain proper tension
on the rope, and the rope shall be identified colored red and yellow.
