Using original electrical accessories it is possible to adapt Agromatic actuators to fulfil special requirements. There is a variety of position controllers and auxiliary switches available for this purpose.
Agromatic has developed a fail-safe module that ensures the electrically powered actuators take up a safe end position if the power supply fails or is disrupted. The direction of rotation of the actuator to take up the safe end position is selected by means of a plug-in jumper. When the power supply is restored, the module switches back to normal operation.
Suitable for actuators powered by an operating voltage of 24 V DC, it is possible to integrate the module in an existing actuator circuit. Only the permanent power supply of 24 V DC is required in addition.
If the power supply fails, the fail-safe module switches to battery operation and moves the actuator to the safe end position selected. During normal operation, the module’s energy accumulator is moved by the supply voltage.
The fail-safe module has been designed for mounting onto standard rail inside a control cabinet. It includes all the electronic components to carry out the function.
