Failure Mode Alarm
If self-diagnostics detect a non-recoverable level controller device
failure, the analog signal will either follow a mode shedding strategy or
switch to a pre-set control signal. All failure mode settings are
user selectable.
Gross failures will drive the analog output high or low according to the
user-selecteable alarm jumper.
Turn-on Time
Digital measured variables will be within specifications
12–14 seconds after power is applied to controller.
Digital and analog control output will be functional within 12–14
seconds after a measured value is obtained.
Temperature Limits
Process (at controller isolator flange):
–40 to 250 °F (–40 to 121 °C).
Ambient:
–40 to 185 °F (–40 to 85 °C).
With LOI: –4 to 125 °F (–20 to 80 °C).
Storage:
–50 to 212 °F (–46 to 100 °C).
With LOI: –40 to 185 °F (–40 to 85 °C).
Damping
Response to step input change can be user-selectable from 0 to 32
seconds for one time constant. This is in addition to sensor response
time of 0.2 seconds.
