4-11-1 Using Remote PV Mode

Remote PV mode forces PID equation output using the input value from the
external sensor with communications functions as the PV of the E5ZN,
instead of using normal thermocouple or platinum resistance thermometer
sensor input.
This function is useful when using a remote external sensor with communica-
tions functions.

1. Connect the sensor input according to the following specifications.
• For TC, Infrared Temperature Sensors, or Analog Input
Short between terminal numbers 5 and 6 and 11 and 12.
• For Pt
Connect a resistance of 100 to 125 W between terminal numbers 4 and 5
and 10 and 11.
• Short between terminal numbers 5 and 6 and 11 and 12.
2. Set the cycle for communications data sent from the external sensor to "re-
mote PV communications wait time." This setting affects both channels.
If the refresh cycle for data from the external sensor is longer than the "re-
mote PV communications wait time," the E5ZN will determine that the ex-
ternal sensor has been disconnected, and an input error will occur.
3. To switch to remote PV mode, turn ON the "remote PV mode" parameter.
This parameter setting is used for both channels.
4. The PV from the external sensor is written to the remote PV.
5. To switch from remote PV mode to normal mode, turn OFF the "remote PV
mode" parameter.
Default Settings
The default settings are shown below.
• Remote PV mode:
• Remote PV communications wait time: 2,000 ms
