(MODE_BLK) Description
Primary value type
(PRIMARY_VALUE_TYPE) OOS Displays the calculation process for the PRIMARY_VALUE.
Display:
Sensor Transducer 1:
• PV = SV_1: Sensor value 1
• PV = SV_1-SV_2: Difference
• PV = 0.5 x (SV_1+SV_2): Average
• PV = 0.5 x (SV_1+SV_2) Redundancy: Average or
Sensor Value 1 or Sensor Value 2 in the event of a
sensor error in the other sensor.
• PV = SV_1 (OR SV_2): Backup function: If sensor 1 fails,
the value of sensor 2 automatically becomes the Primary
Value.
• PV = SV_1 (OR SV_2 if SV_1>T): PV changes from
SV_1 to SV_2 if SV_1 > value T (THRESHOLD_ VALUE
parameter)
Sensor Transducer 2:
• PV = SV_2: Sensor value 2
• PV = SV_2-SV_1: Difference
• PV = 0.5 x (SV_2+SV_1): Average
• PV = 0.5 x (SV_2+SV_1) Redundancy: Average or
Sensor Value 1 or Sensor Value 2 in the event of a
sensor error in the other sensor.
• PV = SV_2 (OR SV_1): Backup function: If sensor 2 fails,
the value of sensor 1 automatically becomes the Primary
Value.
• PV = SV_2 (OR SV 1 if SV_2>T): PV changes from SV_2
to SV_1 if SV_2 > value T (THRESHOLD_VALUE
parameter)
Threshold value
(THRESHOLD_ VALUE) OOS Value for switching in the threshold PV mode. Entry in the
range from–270 to 2
450 °C (–454 to 4 442 °F) -270°C to
2450°C (-454°F to 4442°F)
Primary value max. indicator
(PV_MAX_INDICATOR) AUTO - OOS Max. indicator for PV is stored in the non-volatile memory
in intervals of 10 minutes. Can be reset.
Primary value min. indicator
(PV_MIN_INDICATOR) AUTO - OOS Min. indicator for PV, is stored in the non-volatile memory
in intervals of 10 minutes. Can be reset.
Sensor value (SENSOR_
VALUE) Dynamic / read
only Sensor Transducer 1:
• VALUE = Value of the sensor connected to the S1
terminal group
• STATUS = Status of this value
Sensor Transducer 2:
• VALUE = Value of the sensor connected to the S2
terminal group
• STATUS = Status of this value
Sensor type (SENSOR_ TYPE) OOS Setting for the sensor type.
Sensor Transducer 1: Settings for sensor input 1
Sensor Transducer 2: Settings for sensor input 2

Please observe the wiring diagram in when
connecting the individual sensors. In the case of 2-
channel operation, the possible connection options
in must also be observed.
Sensor connection (SENSOR_
CONNECTION) OOS Sensor connection type:
Sensor Transducer 1:
• 2-wire
• 3-wire
• 4-wire
Sensor Transducer 2:
• 2-wire
• 3-wire
