Failsafe mode channel 1
Description
Use this function to specify behavior in the event of a device alarm.
Options
• Min current
• Max current
• Hold value
• Actual value
Factory setting
Min current
Additional information
The device alarm can be determined at current output 1. The relevant
parameters "Tube not oscillating" and "Density range" can be configured in
the "Supervision" section. In the event of a breakdown of the power supply
the value of the current output is <1 mA. The failure mode in accordance
with NAMUR Recommendation NE 43 is ensured.
Failsafe mode channel 2
Description
Use this function to specify behavior in the event of a device alarm.
Options
• Min current
• Max current
• Hold value
• Actual value
Factory setting
Min current
Additional information
The device alarm can be determined at current output 2. The relevant
parameters "Tube not oscillating" and "Density range" can be configured in
the "Supervision" section. In the event of a breakdown of the power supply
the value of the current output is <1 mA. The failure mode in accordance
with NAMUR Recommendation NE 43 is ensured.
Time constant output
Description
Use this function to enter a delay time of the output signal to fluctuations
in the measured value.
User entry
Positive integer 0 to 120 s
Factory setting
0 s
Additional information
The measure value is averaged over the time entered.
Activate simulation
Description
Switch current output simulation on or off.
Options
• Off
• On
Factory setting
Off
Additional information
Simulation is switched off again following a power failure.
