All. Restart interlock of the V200/V300
handles the reset function (see “Reset”
below).
Always configure the application with restart interlock!
Ensure that there is always a restart interlock. The V200/V300 is unable to verify if the
restart interlock of the machine is connected. If you deactivate both the internal and the
external restart interlock, the users and operators of the machine will be at acute risk of
injury.
Reset
If you activate the restart interlock on the V200/V300 (internal) and also realise a restart
interlock on the machine (external), then each restart interlock gets its own button.
When actuating the reset button (for the internal restart interlock) …
•
the V200/V300 activates the output signal switching devices.
•
switches the V200/V300 to green.
Only the external restart interlock prevents the machine from restarting. After pressing the
reset button for the V200/V300, the operator must also press the restart button for the
machine. If the reset button and the restart button are not pressed in the specified
sequence, the dangerous state must remain disrupted.
The reset button prevents the accidental and inadvertent operation of the external restart
button. The operator must first acknowledge the safe state with the reset button.
The electrical connection of the reset button is described in section 5.3 on page 33. The
configuration of the internal restart interlock is described in section 8.2 “Internal restart
interlock” on page 46.
3.4.2
External device monitoring (EDM)
The V200/V300 has external device monitoring. If you activate the external device
monitoring, then the V200/V300 checks whether the contactors are actually de-energized
when the protective device triggers. If, after an attempted Reset/restart, the EDM does not
detect a response from the switched device within 300 ms, the EDM will deactivate the
output signal switching devices again. In this case the safety camera system signals as
follows:
•
The system remains at red. The status LED
⊃ Ν
illuminates.
•
The status LED
∪ ⌠ϑ
flashes with a short duty cycle
•
The diagnostics LED

⌠ϑ
flashes with a short duty cycle.
