Description

What is the operator keyboard?

The operator keyboard is used by the operator to call out the relevant screen and carry out relevant operations, such as modifying the given value of a circuit, changing the running state of a circuit, carrying out a manual operation on a circuit, confirming alarm, printing reports and so on.

Tips: The engineer keyboard is mainly used for technical personnel configuration. All monitoring points, control circuits, various pictures, alarm lists, process reports, etc. are configured by technicians through the keyboard of engineers.

Honeywell DCS System Exception Handling

1) If the data on the DCS operation interface is not refreshed (once per second in normal cases) and the manual automatic switch cannot be operated, please contact the DCS maintenance personnel for maintenance and immediately go to the site for operation.

2) In the case of transmitter failure, the automatic control process should be cut back to the manual immediately.

3) In the case of the valve actuator and circuit output clamp failure, the on-site operation shall be changed.

4) When the DCS system circuit input card fails, the corresponding control circuit shall be cut back to manual, and the fault card shall be replaced. After checking and confirming the fault is eliminated, it can be put into automatic again.

5) In case of abnormal power failure of the DCS system, the on-site operation shall be changed. After the power is switched on again, the engineer is required to check the system condition, check whether the system data such as loop parameters are normal, and confirm the opening degree of each regulating valve. If there is any abnormality, the configuration should be down-transmitted again. After everything is normal, it can be put into automatic again.

6) Please refer to the operating rules of the post for other abnormal situations.
