The complete enclosure assembly has an environmental rating of IP65. On the front panel there is an emergency stop button [1] and an E-stop reset button [8]. On the right is the on/off switch [5]. An additional input for an external 2-channel (equivalent) emergency stop is provided internally. This can be deactivated as necessary. When one of the two shutdown options is activated, all valves are closed and the power supply to the solenoid valves is interrupted.
To reset after an emergency stop, the emergency stop switch must be unlocked and then acknowledged with the "E-STOP reset" button.
The error message for the emergency stop must be acknowledged separately on the HMI!
The controller power supply is provided via a three-wire mains cable with connector.
The controller power supply is provided via a 5-m-long, three-wire mains cable. The controller is secured internally with a circuit breaker of characteristic B.
The Ethernet port [9] is located on the top. This allows the device to be integrated into a Modbus system.
