Symbol Meaning Danger symbols and information DANGER Immediate danger leading to death or serious injury. CAUTION Possible danger which may lead to minor injury or damage to property. Information on easier and safer working practices. Intended use The control unit is designed for processing the signals of a pressure-sensitive protec- tion device (PSPD).
Ä Do not overload control unit Ensure that the specified switching current is not exceeded. Ä In the event of a fault, put out of operation In the event of malfunctions and visible damage, put the control unit out of oper- ation by decommissioning it.
Product overview Connections Blue Green Yellow Orange Brown Connections: Terminals: Supply voltage 1, 5 Output 6, 5 Sensor 1 2, 3 Sensor 2 4, 3 Function, installation and commissioning Function The control unit has two monitoring circuits, which operate one output circuit. The electronics monitor the electrical resistance of the sensors, which have a defined closed-circuit current.
Installation Danger of injury from electric shock! DANGER Ä Disconnect all devices and live parts in the immediate environment from the power supply and secure them to prevent them from being switched on again (see relevant operating instructions). Ä Check whether all devices and parts are de-energised. Impaired operation due to overheating CAUTION If the control unit overheats, operation of the protection device may be impaired.
2. Wire the sensors, relay contacts and supply voltage to the cable terminals. Output Sensor 1 Sensor 2 Overall safety endangered CAUTION Overall safety is affected by the quality and reliability of the interface between the protection device and the machine. Ä...
