Use in safety instrumented systems Temperature transmitter iTEMP TMT82
22 Endress+Hauser
5.3 Parameters and default settings for the SIL mode
The following parameters affect the safety function. It is recommended that configured or
changed values be noted down.
Parameters and default settings for the expert mode
Firmware version Use this function to view the device firmware version installed. Display
max. 6-digit character string in the format xx.yy.zz. The firmware version
that is currently valid can be taken from the nameplate or the Operating
Instructions associated with the device.
Serial number Use this function to display the serial number of the device. It can also be
found on the nameplate. Max. 11-digit character string comprising letters
and numbers.
Enter access code Use this function to enable the service parameters via the operating tool.
Factory setting: 0
Device reset Use this function to reset the device configuration - either entirely or in
part - to a defined state.
Factory setting: Not active (default setting for SIL mode, cannot be
changed)
Hardware revision Use this function to display the hardware revision of the device.
Simulation current output Use this function to switch simulation of the current output on and off.
The display alternates between the measured value and a diagnostics
message of the "function check" category (C) while simulation is in
progress.
Factory setting: Off (default setting for SIL mode, cannot be changed)
Value simulation current output Use this function to set a current value for the simulation. In this way,
users can verify the correct adjustment of the current output and the
correct function of downstream switching units.
Factory setting: 3.58 mA (default setting for SIL mode, cannot be
changed)
Current trimming 20 mA Use this function to set the correction value for the current output at the
end of the measuring range at 20 mA .
Factory setting: 20.000 mA (default setting for SIL mode, cannot be
changed)
Current trimming 4 mA Use this function to set the correction value for the current output at the
start of the measuring range at 4 mA .
Factory setting: 4 mA (default setting for SIL mode, cannot be changed)
Lower range value Use this function to assign a measured value to the current value 4 mA.
Factory setting: 0
Upper range value Use this function to assign a measured value to the current value 20 mA.
Factory setting: 100
Out of range category Use this function to select the category (status signal) as to how the
device reacts when the value is outside the set measuring range.
Factory setting: maintenance required (M)
Error current Use this function to set the value the current output adopts in an alarm
condition.
Factory setting: 22.5 mA
Failure mode Use this function to select the signal on alarm level of the current output
in the event of an error.
Factory setting: High alarm
HART
®
address Definition of the HART
®
address of the device.
Factory setting: 0 (default setting for SIL mode, cannot be changed)
Device revision Use this function to view the device revision with which the device is
registered with the HART
®
Communication Foundation. It is needed to
assign the appropriate device description file (DD and DTM) to the device.
Factory setting: 3 (fixed value)
