Alarm and Saturation Level Configuration
Fast Keys | 1, 4, 2, 7 |
|
|
Failure mode alarm and saturation levels can be configured using a HART Communicator or AMS, see “Alarm and Saturation Level Configuration” on page
•Low alarm level must be less than the low saturation level
•High alarm level must be higher than the high saturation level
•High saturation level must not exceed 21.5 mA
•Alarm and saturation levels must be separated by at least 0.1 mA
The HART Communicator or AMS will provide an error message if a configuration rule is violated.
To configure alarm and saturation levels with a HART Communicator or AMS perform the following procedure:
HART Communicator
1.From the HOME screen, follow the fast key sequence for “Alarm and Saturation Levels”.
2.Select 7, Config. Alarm Level to configure alarm levels.
3.Select OK after setting the control loop to manual.
4.Select OK to acknowledge current settings.
5.Select desired setting, if “OTHER” is selected enter HI and LO custom values.
6.Select OK to acknowledge the loop can be returned to automatic control.
7.Select 8, Config. Sat. Levels to configure saturation levels.
8.Repeat steps
