Danger!
Danger to life from missing safety function
If the safety loop is put out of service, the safety function is no longer guaranteed.
• Do not deactivate the device.
• Do not bypass the safety function.

Operating the device
1.
Observe the safety instructions in the instruction manual.
2.
Observe the information in the manual.
3.
Use the device only with devices that are suitable for this safety application.
4.
Correct any occurring safe failures. Take measures to maintain the safety function
while the device is being repaired.
The device has 2 limit values LIM1 and LIM2 and the corresponding delay times.
The delay times can be adjusted separately.
If the defined limit value is exceeded and after the set delay time has expired,
the corresponding volt-free switching contact is opened.
A subsequent fall below the limit value is also signaled at volt-free switching contacts 1 and 2,
i. e. the respective switching contact automatically closes.
• This is used for a device with pre-alarm and main alarm to generate a pre-alarm
and a main alarm.
• This is used for a device with window function to generate a signal for the lower
and upper switching threshold.
The device also has an analog current output. This supplies direct current of 4 mA to 20 mA
proportional to the vibration variable.
