Page 4: Preliminary Note
1 Preliminary note The instructions are part of the unit. They are intended for authorised persons according to the EMC and Low Voltage Directives and safety regulations. The instructions contain information about the correct handling of the product. Read the instructions before use to familiarise yourself with operating conditions, installation and operation. -
Page 5: Safety Instructions
2 Safety instructions • Follow the operating instructions. • Improper use may result in malfunctions of the unit. This can lead to personal injury and/or damage to property during operation of the machine. For this reason note all remarks on installation and handling given in this document. Also adhere to the safety instructions for the operation of the whole installation. -
Page 6: Items Supplied
3 Items supplied • 1 safe standstill monitor DA102S including 5 Combicon connectors with screw terminals • 1 original operating instructions "Safe standstill monitor" reference no. 80001217. If one of the above-mentioned components is missing or damaged, please contact one of the ifm branch offices. -
Page 7: Requirements For The Hardware Configuration
The following points have to be ensured in the application by taking administrative measures: • The devices of type "safe standstill monitor", DA102S, in operation must be subjected to a self-test (switching on) within a period of maximum 6 months (intermittent operation). -

Page 9: Switching Function
5.3 Switching function In accordance with a "safe standstill message", the output relays are energised when the switch point is not reached or with standstill. The output relays K1/K2 switch (are energised) when the set switch point is 5% below the set level. They switch back (are de-energised) when the set switch point is exceeded by 5%. -
Page 10: Y7 Transistor Output
5.6 Y7 transistor output The Y7 transistor output provides a non-safety related signal for communication to a PLC. Status Y7 transistor output Normal operation (no error) HIGH (ON) Error LOW (OFF) The output data is compatible with the input data of the current-sinking inputs of type 1, 2, 3 to EN 61131-2. -
Page 11: Error Message
The device monitors continuously if this condition is met. If this regulation is violated, there is an error and the device goes into the safe state. (→ 6.3 Arrangement of the damping cams) 5.9 Error message If the device detects an error, the switching outputs are kept in the safe state. The "Fault"... -
