HE 5750 Operating Instructions
#371627 | Version 1.1

25

7.6 Local operation on the switch cabinet

The control of the filter system can be started or stopped locally. The condition of the local
controller is reported to the process control.

1 = Controller in operation
2 = Cleaning in process
3 = Alarm
4 = Activating local operation
5 = Starting local cleaning
6 = Acknowledging active alarms

Operation on the switch cabinet

7.7 Limitation of local operation

The operation of the local control elements may be locked by a parameter.

Selection:

>F5, >F1: parameters >interfaces >local interface Yes / No.

Even if the local operation is locked, the indicator lights function.
The operation of the keys at the controller can be limited to ‘display only’ by the control level
(remote operation, remote control = On). This limitation can only be reversed via the operator
level or via ‘SmartTool’. After expiration of the ‘Remote timeout’, the keyboard operation is
unlocked again too, in case of an interruption of the connection to the process control.
