The output current level will be 12mA.
• SIMULATION ENABLED FOR: Select the desired length of time that simulation will be enabled.
When the programmed time has elapsed, analog output simulation will turn off. If 81/,0,7(' is
selected, simulated analog output will be used until simulation is turned off via the 6,08/$7,21 21
2)) setpoint or via the serial port or until control power is removed from the 239.
e) SWITCH INPUTS SIMULATION
SIMULATION: Enter 21 to switch from actual switch inputs to the programmed simulation status
•
of each switch input. While simulation is on the actual switch input status will be overridden by
the simulated status of each input. 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 the 6 7(67,1*?6:,7&+ ,13876 6,08/$7,21?6,08/$7,21 (1$%/(' )25 set-
point has elapsed since simulation was first enabled
When switch inputs simulation is turned on the following flash message will be displayed for 3
seconds.
When switch inputs simulation is turned off the following flash message will be displayed for 3
seconds.
EMERGENCY RESTART INPUT: Enter the status of this switch input as 23(1 or &/26(' . The
•
functionality of this input remains as is with actual input connected.
EXTERNAL RESET INPUT: Enter the status of this switch input as 23(1 or &/26(' . The function-
•
ality of this input remains as is with actual input connected.
OPTION 1 INPUT: Enter the status of this switch input as 23(1 or &/26(' . The functionality of this
•
input remains as is with actual input connected.
OPTION 2 INPUT: Enter the status of this switch input as 23(1 or &/26(' . The functionality of this
•
input remains as is with actual input connected.
• SIMULATION ENABLED FOR: Select the desired length of time that simulation will be enabled.
When the programmed time has elapsed, switch inputs simulation will turn off. If 81/,0,7(' is
selected, simulated switch input status 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.
f) THERMISTOR SIMULATION
SIMULATION: Enter 21 to switch from actual thermistor input to the programmed simulation
•
thermistor resistance value. While simulation is on the actual thermistor input will be overridden
by the simulated resistance value. 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
•the time programmed in 6 7(67,1*?7+(50,6725 6,08/$7,21?6,08/$7,21 (1$%/(' )25 setpoint
has elapsed since simulation was first enabled
