Description
Activates write protection for the entire device
• On: locked
• Off: unlocked
Select the 'Input Sensor 1' submenu.
Select the 'Input Sensor 2' submenu.
Input / output assignment Selects the inputs that are mapped to the current.
see table of input / output assignment
Configures the type of redundancy
• Availability: If one of two sensors fail, the measurement with the valid measurement of the good sensor continues. The
diagnostics informs about the defective sensor.
• Safety: If one of two sensors fail, current output signals alarm current. Also diagnostics informs about the defective
sensor.
Select the 'PV Measured range' submenu.
Configurable τ 63% output signal damping value
Value range: 0 to 100 s
Selects sensor type:
see table of sensortypes ... / Easy Setup / sensortype S1
Sensor connection type relevant for all Pt, Ni, Cu resistance thermometers
• two-wire: Sensor connection type in two-wire technology
• three-wire: Sensor connection type in three-wire technology
• four-wire: Sensor connection type in four-wire technology
Sensor line resistance relevant for all Pt, Ni, Cu resistance thermometers with a two-wire circuit
Value range: 0 to 100 Ω
Cold junction compensation for thermocouples:
• Internal: Use of internal cold junction temperature of the transmitter when using thermal compensating cable.
• External - fixed: Use of external fixed cold junction temperature of the transmitter when constant thermostat
temperature is used (can be set with external cold junction temperature 2).
• None: no thermocouple cold junction compensation (CJC)
• Sensor 1 temperature: Use of sensor 1 as cold junction temperature for sensor 2
Relevant for external cold junction compensation, specification of constant external cold junction temperature
Value range: -50 to 100 °C
Selects the physical unit for the sensor measuring signal
Units: °C, °F, °R, K, mV, Ω, V, kΩ
Defines the value for 4 mA (adjustable)
Defines the value for 20 mA (adjustable)
