Functions

8.9 SensorFlash

8.8.2

Dosing operation

When the transmitter recipes have been configured, the active recipe is selected in
parameter 2.5.3 "Active Recipe". The transmitter output changes according to the dosing
operation and controls the valve in the dosing process. The digital input can be configured to
start dosing. LUI provides dosing control via menu 3.10.1 Control Dosing for test purpose. All
dosing setup and control can be performed via HART interface using SIMATIC PDM.
8.8.3

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 2.5.4.6.2). If the duration time is exceeded,
an alarm will be triggered, see "Alarms and system messages" (Page 139).
Dosing overrun monitoring
The dosing overrun monitoring checks if the flow amount exceeds the defined Overrun Value
(menu item 2.5.4.6.4). If the overrun value is exceeded, an alarm will be triggered, see
"Alarms and system messages" (Page 139).
This function can detect a valve malfunction (non-closure) caused by a blockage, wear, etc.
8.9 SensorFlash
SensorFlash is a standard, micro SD card with the ability to be updated by PC. It is supplied
with each sensor with the complete set of certification documents including calibration report.
Material, pressure test, factory conformance and O
ordering.
The Siemens SensorFlash memory unit offers the following features and benefits:
● Audit trail including any values or settings changed by users is stored automatically
● Automatically program any similar transmitter in seconds to the operation standard
● Transmitter replacement in less than 5 minutes
● True "plug & play" provided by integrated cross-checking data consistency and HW/SW
