Diagnosis / error messages
10.1
HART/DTM diagnostic information
Configuration has been changed.
NOTICE
The transmitter signals changed configuration or parameter
setting by setting the HART flag "Configuration-changed".
The message can be acknowledged via the HART-DTM.
10.2
Analog output / LED diagnostic information
The TTR200 features a green and a red diagnostic LED for
fault signaling.
The green LED indicates that the supply voltage is connected
and the red LED provides fault information about the sensor,
sensor lead and unit; this information corresponds to
"Over/underrange" for the output signal in the 4 ... 20 mA
current loop.
NOTICE
After connecting or switching the supply voltage, it may take
up to max. 15 seconds until this is acknowledged by the
green LED. If neither the green nor the red LED lights up
after this period, the unit is defective.
As a rule, the green or the red LED lights up. For this reason,
when faults related to the sensor, sensor lead or unit are
signaled by the red LED, the green LED does not light up,
although the supply voltage is connected. If a sensor or unit
fault is detected, the red LED indirectly signals that the supply
voltage is connected. Once the sensor or unit fault is
eliminated and the red LED turns off, the supply voltage signal
appears in the green LED.

Maintenance
WARNING
Risk of explosion!
Faulty transmitters may not be placed into operation by the
user.
Repairs must be performed from ABB service.
For transmitters that are used as intended under normal
operation, no maintenance is required.
No on-site repair or replacement of electronic parts is planned.
11.1
Cleaning
When cleaning the exterior of meters, make sure that the
cleaning agent used does not corrode the housing surface and
the gaskets.

Repair
12.1
Returning devices
Use the original packaging or a secure transport container of
an appropriate type if you need to return the device for repair
or recalibration purposes. Fill out the return form (see the
Appendix) and include this with the device.
According to the EU Directive governing hazardous materials,
the owner of hazardous waste is responsible for its disposal or
must observe the following regulations for shipping purposes:
