Dosing compensation
In static applications the flowrate is constant. Thus, the dosing compensation, if required, is
fixed. Use the fixed compensation by entering the amount in menu item 2.5.5.5.2 (Fixed
Compensation).
8.8.4
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 Alarms and system messages (Page 171).
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 Alarms and system messages (Page 171).
This function can detect a valve malfunction (non-closure) caused by a blockage, wear, etc.
8.9
Audit trail
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, HART or USB) the change was made.
The transmitter can log up to 100 entries in each of the audit trail log lists:
● "Parameter Change Log" (menu item 3.8.1)
● "FW Update Change Log" (menu item 3.8.3)
Each audit trail list can be cleared by the user.
See also "Alarm History Log" (menu item 3.2.4)
8.10
Alarm acknowledgement
All unacknowledged alarms are listed in alarm log list "Alarm" menu item 3.2.3. The alarm list
is default available in operating view 6.
There are two ways to have the alarms removed from the alarm list (menu item 3.2.2).
● Manual: The alarm remains in the alarm list until the alarm is manually acknowledged
(ack.).
