When thermistor simulation is turned on the following flash message will be displayed for 3 sec-
onds.
When thermistor simulation is turned off the following flash message will be displayed for 3 sec-
onds.
• THERMISTOR RESISTANCE: Enter the value of the thermistor resistance to be simulated. The
functionality of the thermistor remains as is with an actual input connected to the 239.
• SIMULATION ENABLED FOR: Select the desired length of time that simulation will be enabled.
When the programmed time has elapsed, thermistor simulation will turn off. If 81/,0,7(' is
selected, simulated thermistor input will be used until simulation is turned off via the 6,08/$7,21
212)) setpoint or via the serial port or until control power is removed from the 239.

g) RTD SIMULATION
• SIMULATION: Enter ON to switch from actual input to the programmed simulation temperature
value of each RTD input value. While simulation is on all three RTD r inputs will be overridden by
the simulated temperature values. Set this setpoint to 2)) after simulation is complete. As a safe-
guard, simulation will automatically turn off if:
•power to the 239 is turned off and on
•time programmed in 6 7(67,1*?57' 6,08/$7,21?6,08/$7,21 (1$%/(' )25 setpoint has
elapsed since simulation was first enabled
When RTD simulation is turned on the following flash message will be displayed for 3 seconds.
When RTD simulation is turned off the following flash message will be displayed for 3 seconds.
• RTD 1/2/3 TEMPERATURE: Enter the value of the each RTD temperature to be simulated. The
functionality of the RTDs remains as is with actual inputs connected to the 239.
• SIMULATION ENABLED FOR: Select the desired length of time that simulation will be enabled.
When the programmed time has elapsed, RTD simulation will turn off. If 81/,0,7(' is selected,
simulated RTD input will be used until simulation is turned off via the 6,08/$7,21 212)) setpoint
or via the serial port or until control power is removed from the 239.
