5.4 Loop Check (Simulation output)
You can force the analog output, digital output, and valve control output to a given state. This
section explains how to do this. You can use this function to check the operation after wiring.
5.4.1 Executing a Loop Check
This section explains the loop check setup procedure for each output type separately. A loop
check can be executed simultaneously on all terminals of all types.
Execution menu path:
[HART] “Diagnosis/Service>>Loop check”
[YH8000] “ >>Execution>>Loop Check”
NOTE
If you turn off the TDLS8000 while performing a loop check, loop check will be cleared.
l
Analog output
Open the Analog output menu, and set Loop check mode to Enable to output the specified
simulated current (“check output”).
NOTE
If multi-drop mode is set on HART, loop checking of AO-1 via HART is not possible.
l
Digital output
Open the Digital output menu, and set Loop check mode to Enable to output the specified
simulated state (“check output”).
l
Valve control output (SV)
Open the Valve output menu, and set Loop check mode to Enable to output the specified
simulated state (“check output”).
5.4.2 Auto Release Function
The auto release function automatically clears loop checking on all terminals and restores normal
output after the specified time elapses. The auto release counter starts when any of the loop
check is enabled. The counter restarts whenever a loop check setting is changed. When the
counter expires, all loop checking is disabled.
To set the auto release time, set Auto release time in the Loop check menu. If you select Disable,
the auto release function is disabled, and the simulated output is maintained until you manually
clear the loop check mode. The specified values are retained even after the power is turned off.
