4.3.3.4 Setting electrical damping
.
Note
The time response of the SITRANS P transmitter is determined by the dead time, the time
constant T
63
(see Chapter 1.3, Page 7), and the electrical damping value.
The SITRANS P transmitter is supplied with a damping value of 0.1 s. Values of 0 to 100.0 s in increments
of 0.1 s are permitted.
- Select mode 4 using the
M
key
- Use the
and
keys to change the damping value
4.3.3.5 ”Loop check” function
The following output current constants can be set to check the output signal loop, e.g. during commission-
ing, irrespective of the pressure:
3,6 mA
4,0 mA
12,0 mA
20,0 mA
22,8 mA
- Select mode 8 using the
M
key
- Press the
and
keys simultaneously for about 2 s. This activates the ”loop check” function. An
output current of 4.0 mA is displayed.
- Use the
and
keys to select the required current
Changing the mode disables the “loop check” function.
4.3.3.6 Output current in error situations
The pressure sensor and electronics are monitored continuously. If a defect occurs
is displayed.
The output current is set to 3.6 or 22.8 mA, neither of which are possible under normal conditions. The
value set is determined using mode 9. The factory setting is 22.8 mA.
-
Select mode 9 using the M key.
-
Use the
or
key to select either 3.6 mA or 22.8 mA.
Changing the mode causes the selected value to be stored.
