Ma Output Parameters (P201 To P219); Independent Ma Setpoint Parameters (P210 And P211) - Siemens SITRANS LR 300 Instruction Manual

mA Output Parameters (P201 to P219)

P201 mA Output Function (F = 1)
Alters the mA output/measurement relationship. Set independently from P001. This
determines the primary variable for HART/Profibus PA, and should not be changed if
using HART.
Values
Selection can be done locally, or from the Master, using the Primary Variable exchange.
Note:
• Ensure the master is off-line with the device when changing this value locally.
Changes will affect the mAmp Output directly, and can cause serious problems if
under automatic control.
• Selection also affects the secondary, tertiary, and quaternary variables.
• 0 (manual) setting is required to utilize P911. Remember to change back to previous
setting after P911 usage.

Independent mA Setpoint Parameters (P210 and P211)

Use these features as a reference for calculating the minimum and/or maximum mA
output to any point in the measurement range.
For HART/Profibus PA, 4 mA and 20 mA represent the upper and lower range limits for the
primary variable.
Note : Ensure the % symbol is displayed before entering a % value.
