4 Product description
The SAFEONE DN3PS2 is a safety switchgear for sensorless standstill monitoring of electric
drives.
In the event of drive movement or errors, the potential-free NO output contacts switch to
the rest position.
The restart can be parameterized with a time delay.
The readiness for operation and the switching status of the contact outputs are displayed
via LEDs.
The device is intended for mounting on a 35mm standard rail.
4.1 Function description
Standstill is detected by evaluating the induced voltage (EMF) when the motor is coasting.
After applying the operating voltage (24 V DC) to terminals A1 and A2, the safety relay
will operate a self-test. The safety relay is in safe condition for the duration of the self-
test. The LED OK lights up red.
The device is ready for operation, when the LED OK lights up green.
If the voltage measured at the measuring inputs is lower than the switching threshold S1
set on the device, the enabling current path switches on with a time delay. The STOP
LED lights up green.
The enabling current path opens immediately when the measured voltage exceeds the
set switching threshold S2. The STOP LED goes out.
CAUTION
Note that the method of frequency measurement does not recognize a mechanically
blocked motor.
WARNING
The wire break error is automatically acknowledged as soon as the error is no longer pre-
sent.
►Ensure suitable protective measures to prevent an automatic restart.

◄Enable contacts close when the drive is at
standstill.
►I11 und I21 connected
◄Standstill monitoring is not active.
◄Enable contacts are closed 1)
◄The "wire break" and "single-channel"
error detection is inactive. 2)

4.1.4 Example of application
When the protective device is open, inputs I11 and I21 are not connected. Standstill monitoring
is active and the enabling current path only closes when the drive is at standstill.
When the protective device is closed, standstill monitoring is not active and the enabling current
path is closed

4.2 Configuration
The switching thresholds and the switch-on delay are set using the SET button on the front. The
two-color LEDs b1, b2, b4, b8 show the current status in binary code.
During the setting mode, the safety function and error monitoring are active.
If the operating voltage is interrupted during the setting mode or if no button is pressed
for ≥20s, the setting is ended without being saved. The previous parameter values re-
main effective.
The parameterization is not possible if an error (e.g. wire break) is present.
WARNING
The correct setting of the parameters is a prerequisite for safe operation and is the
responsibility of the user.
A VDE-insulated screwdriver according to EN60900 must be used to press the SET
button.
4.2.1 Setting the switching thresholds
►Hold down the SET button for 3s until all LEDs flash red.
◄The LEDs flash according to the currently set switching threshold.
►You can change the switching threshold by briefly pressing the SET button.
◄The LEDs show you the setting according to Table 4 1.
►Keep the SET button pressed for 2s.
◄The set value is saved and the setting mode is exited.
