The maximum function reserve is achieved with the following settings:
• Transmitting power: 100%
• Receiving sensitivity: 22
• Switching threshold: low value, e.g. 40%
4.14 Validation output
The light curtain can signal measurement readiness to the control via a digital output.
The light curtain does not deliver any stable measurement values e.g. during a teach event (teach-in).
In the menu of the receiver control panel, configure an IO pin as a validation output.
Select Digital IOs > IO Pin > IO Function > Validation output.
You can configure IO Pin2, IO Pin5 or IO Pin6 as a validation output. Only one IO pin can be configured
as a validation output.
4.15 Key lock
The
Key lock
function prevents entries and configuration changes from being made via the membrane
keyboard on the receiver control panel.
The
Key lock
function can be activated via IO-Link or by means of a signal to an IO pin configured as a
teach input. The two activation types are independent of each other.
Activating key lock via IO-Link
Select Display Key Lock in the
Sensor Studio
configuration software (see chapter 12 "Connecting to a
PC – Sensor Studio").

Signal at IO pin configured as teach input
In the menu of the receiver control panel, configure an IO pin as a teach input.
Select Digital IOs > IO Pin > IO Function > Teach input.
You can configure IO Pin2, IO Pin5 or IO Pin6 as a teach input. Only one IO pin can be configured as
a teach input at any one time.
Apply a static signal to the IO pin which has been configured as a teach input.
• IO Logic “Positive PNP”: +24 V
• IO Logic “Negative NPN”: 0 V or “Open cable”
Deactivating key lock
Deactivation of the key lock if the key lock was inadvertently activated during configuration at the receiver
control panel.
Deactivating key lock via IO-Link

To debounce the validation signal, it is recommended to configure a waiting time of 100 ms in
the control.
After the device has been switched on, measurement readiness is NOT signaled when triggering
is activated and the trigger-input signal is missing.
The
Key lock
function cannot be enabled or disabled via the teach input.
