Function mode Selection of device function
• One sensor input
• Two sensor inputs
Note! Selection only active on two sensor input device.
PV mode For selecting the calculation function of the PV (PV = primary value). The
PV is shown linear at the analog output.
• PV = Sens1
Sensor 1 is the primary value (PV)
• PV = Sens2
Sensor 2 is the primary value (PV)
• PV = Sens1-Sens2
Difference
• PV = (Sens1 + Sens2)/2
Average of sensor 1 and 2
• PV = Sens1 (or Sens2) backup
Sensor 2 becomes PV if sensor 1 fails. An error signal is not output. If the
active backup = switch to redundant sensor, the display shows the
"Caution" icon, the corresponding error number (see chapter 9) and the
text ' b ack' .
• PV = Sens2 (or Sens1) backup
Sensor 1 becomes PV if sensor 2 fails.
• PV = Sens1 (Sens2, if Sens1 > T)
If temperature T is overshot at sensor 1, the measuring temperature of
sensor 2 becomes the PV. The system switches back to sensor 1 if the
measuring temperature at sensor 1 is at least 3.6 °F (2 °C) below T. S1 or
S2 appears on the display to indicate which sensor is currently active.
The temperature-dependent switchover means that 2 sensors can be
combined, which each have certain advantages in different temperature
ranges.
Note! Selection only active on "Function - Two sensor inputs".
Temperature T Switch to sensor 2
Entry only relevant if PV mode is ' P V = Sens1 (Sens2, if Sens1 > T)'
Note! Selection only active on "Function - Two sensor inputs".
PV unit Input for PV unit
Input: °C, F, K, R, mV or 
Note! The setting PV unit has priority, the selection list of the sensor type is
shown independently from the PV unit.
