When analog output simulation is turned on the following flash message will be displayed
for 3 seconds.
SIMULATION
HAS BEEN ENABLED
When analog output simulation is turned off the following flash message will be
displayed for 3 seconds.
ANALOG OUT SIMULATION
HAS BEEN DISABLED
• ANALOG OUTPUT FORCED TO: Enter in percent the analog output value to be
simulated. Whether the output is 0-1mA, 0-20mA or 4-20mA is dependent upon the
selection in S1: 239 SETUP/ANALOG OUTPUT/ANALOG OUTPUT RANGE
EXAMPLE:
Alter the setpoints below as shown:
S1:239 SETUP/ANALOG OUTPUT/ANALOG OUTPUT RANGE: 4-20 MA
S5:TESTING/ANALOG OUTPUT SIMULATION/ANALOG OUTPUT FORCED TO:
50.0%
S5:TESTING/ANALOG OUTPUT SIMULATION/SIMULATION: ON
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 UNLIMITED is selected, simulated analog output will be used until simulation is
turned off via the
SIMULATION ON/OFF
power is removed from the 239.
• SIMULATION: Enter ON 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
after simulation is complete. As a safeguard, simulation will automatically turn off if:
•power to the 239 is turned off and on
•time programmed in the
SIMULATION\SIMULATION ENABLED FOR
simulation was first enabled
When switch inputs simulation is turned on the following flash message will be
displayed for 3 seconds.
