Fault handling

The transmitter fault handling provides monitoring of both dosing time and amount. The
configuration of the fault handling is done in menu 2.5.4.6 Fault Handling.
Dosing timeout monitoring
The dosing timeout monitoring checks whether the dosing procedure has been finished within
the configured Duration Time (menu item 2.5.5.7.2 for Recipe 1). If the duration time is
exceeded, an alarm will be triggered, see Fault codes and corrective actions (Page 202).
Dosing overrun monitoring
The dosing overrun monitoring checks if the flow amount exceeds the defined Overrun Value
(menu item 2.5.5.7.3 for Recipe 1). If the overrun value is exceeded, an alarm will be triggered,
see Fault codes and corrective actions (Page 202).
This function can detect a valve malfunction (non-closure) caused by a blockage, wear, etc.
8.9 Audit trail logging
The audit trail includes any values or settings changed by users. The audit trail is automatically
stored with information on the change as well as the time (real-time) and by which interface
(display, bus communication or USB) the change was made.
Audit trail information is logged on the SensorFlash card, as a parameter and command
change file which include below informations:
● Timestamp
● MODBUS register
● Previous value
● New value
● Data type
● Interface ID
Example: 2017-06-08 13:48:05;9003;73;74;Uint8;HMI
The transmitter can log up to 100 entries in each of the audit trail log lists:
● "Parameter change log" (menu item 3.9.1)
● "Firmware update change log" (menu item 3.9.3)
Each audit trail list can be cleared by the user.
