4 Function description
4 Function description
The two-channel evaluation unit of the safety module measures the frequency of the rotating field
on the motor at the measurement inputs U, V, W and evaluates the direction of rotation based on
the phase position of the motor drive voltage U, V, W.
A change in the direction of rotation changes the switching status of the enabling current path
13/14, 23/24.
Operation on electrical power drive systems with adjustable speed is possible. Operation on a
single-phase motor is not possible.
WARNING
The device is only suitable for asynchronous motors. When using frequency converters, the
supply voltage of 277V AC (480V AC phase to phase) must not be exceeded.
Note
The direction monitoring takes place in the frequency range 5 Hz to 100 Hz.
The enabling current path remains switched on at frequencies <5Hz. At frequencies> 100Hz,
the previous state of the outputs is retained.
4.1 Acknowledge Input
The acknowledgment input enables the enabling current path to be switched on.
The start takes place with a falling edge of a 24V signal. The start signal is subject to time monitoring.
The 24V signal must be present at input Q for at least 200ms and a maximum of 10s.
4.2 Signal outputs
You can use the signal outputs O1 and O2 to control e.c. a non-safety PLC or signal units.
The message outputs have the following properties:
• 24V, digital
• potential-bound
• short circuit and overload protection
• not safety-related
The output O1 indicates the state of the enabling current path.
The output O2 indicates the operational readiness. This switches off in case of an error.

.4.3 LED-Display
The safety switchgear indicates its operational readiness and the status of the enabling
current path by the two-color LEDs „OK“ and .
The module is ready for operation when the OK LED lights up green.

3Disconnect the device from the power supply before starting work.
3
Wire the device according to the intended use.
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. All enabling current
paths are open.
After a successful self-test, the device is ready for operation. The LED OK lights up green.
3
Start the drive and acknowledge via the acknowledgment input.
3
Check whether the enabling current path switches on in the desired direction of rotation and
switches off in the opposite direction. The switching states can be changed by swapping
phases U and V.
CAUTION
The drive must not be able to brake within 20ms at a speed corresponding to 100Hz, to change
the direction of rotation and back to 100Hz accordingly to accelerate.
CAUTION
Note that the method of frequency measurement does not recognize a mechanically blocked
motor or an overloaded motor!
6 Diagnostics
The safety switching device shows diagnosed errors that lead to a safe condition of the device
by means of a flashing code of the "OK" LED on the device.
The flashing code is repeated continuously with a pause of 1 s.
The meaning of the individual flashing codes can be found in the table.

7 Example of application
7 Example of application
Measuring inputs The measurement inputs U, V, W of the DN3PR1 are directly connected
to the three phases of the motor M.
Switch off safely When the DN3PR1 detects a change of direction, the enabling current paths
13/14, 23/24 open and shut down the motor in a safety-related manner.
Resetting the
safety function
The acknowledgment button S1 is used to reset the safety function after
the motor turns again in the preferred direction.
Monitoring of external
contactors
The external, positively driven contactors K1, K2 are integrated in the start
circuit of the safety switching device.
