SIG ERROR
Factory setting:
SIG ERROR option: ERROR OFF
SIG ERROR SAFEPOS option: CLOSE
This function is used to detect the loss of the input signal, but only for the 4-20 mA input signal option. The error condition
results when input signal ≤ 3.5 mA. This condition occurs when SIG ERROR is enabled, and an error is detected. “ERROR” will
be displayed on the operating interface.
To activate the SIG ERROR option, the user must first adjust SAFEPOS to desired percentage, as seen in Figure 20. After
setting “SIG ERROR” to “ERROR ON” and “SAFEPOS” to “OPEN” and if an error condition is detected, the valve stroke will
shift to the set SAFEPOS value.
Use the arrow keys to scroll to SIG ERROR and press the ENT key to open the selection menu. Use the arrow keys to navigate
to a specific function. Use the SEL key to set the desired feature. Press the EXIT key to return to the main menu.
