Digital output (3)
First select an alarm block (Alarm 1, Alarm 2, Alarm 3 or Alarm 4) for the limit value settings.
Navigate to: Setup → Advanced setup → Application → Alarm → Alarm X
Setting
• Alarm mode = On
• Alarm value source = Tank level (depending on the source)
• HH alarm value, H alarm value, L alarm value and LL alarm value must be configured in line
with the application such that the valid range is within the HH, H and L, LL limits.
Make sure that the correct output is configured (Digital A1-2, Digital A3-4, Digital B1-2, Digital
B3-4, Digital C1-2, Digital C3-4, Digital D1-2, Digital D3-4).
Navigate to: Setup → Advanced setup → Input/output → Digital Xy-z
Setting
• Operating mode = Output passive
• Digital input source = selected alarm block: Alarm 1 any, Alarm 2 any, Alarm 3 any or Alarm 4
any
• Used for SIL/WHG = Enabled must be set to use this digital output as a SIL output.
Calibration of the measuring point - safety function 2 (current input measurement)
The calibration of the measuring point is described in the Operating Instructions (→  7).
Specify which type of configuration c) or d) should be used. Both configurations can apply in parallel
or in combination with safety function 1 (level measurement).
c) Analog input (source) (1) -> safety-related signal: analog output (2)
d) Analog input (source) (1) -> safety-related signal: digital output (3)
Analog input (source) (1)
Make sure that the correct source is configured (Analog I/O B1-3 or Analog I/O C1-3).
Navigate to: Setup → Advanced setup → Input/output → Analog I/O
Setting
• Operating mode = 4..20mA input or HART master+4..20mA input
• Analog input 0% value must be set correctly.
• Analog input 100% value must be set correctly.
Analog output (2)
Make sure that the correct output is configured (Analog I/O B1-3 or Analog I/O C1-3).
Navigate to: Setup → Advanced setup → Input/output → Analog I/O
Setting
• Operating mode = 4..20mA output or HART slave +4..20mA output
• Analog input source = AIO B1-3 value mA or AIO C1-3 value mA (depending on the source)
• 0 % value
• 100 % value
• Used for SIL/WHG = Enabled
Digital output (3)
First select an alarm block (Alarm 1, Alarm 2, Alarm 3 or Alarm 4) for the limit value settings.
Navigate to: Setup → Advanced setup → Application → Alarm → Alarm X
Setting
• Alarm mode = On
• Alarm value source = AIO B1-3 value mA or AIO C1-3 value mA (depending on the source)
• HH alarm value, H alarm value, L alarm value and LL alarm value must be configured in line
with the application such that the valid range is within the HH, H and L, LL limits.
Make sure that the correct output is configured (Digital A1-2, Digital A3-4, Digital B1-2, Digital
B3-4, Digital C1-2, Digital C3-4, Digital D1-2, Digital D3-4).
Navigate to: Setup → Advanced setup → Input/output → Digital Xy-z
