b. Confirm that Menu 08 is set to enable analog fault signalling: display should read
F: Hi or F: Lo. (If there is a fault condition, it will read F= Hi or F= Lo, when buttons
are released.)
c. Check that the current goes to the alarm position (3.6 or 22 mA) if the coaxial
plug is unplugged: at menu 00, the LCD should display – ooL. After the test,
replace the coaxial plug.
d. Confirm that Menu 18 is set to enable digital fault signalling: the LCD should
display F= cc or F= co, when buttons are released.
e. Check that the solid-state output goes to the alarm position (open/close) if the
coaxial plug is unplugged. After the test, replace the plug.
f. Via HART:
Check that the PV goes to 0 pF when the coaxial plug is unplugged, (
0.15 pF is
allowed). If it does, switch the output current to 4 mA and check the current
through the loop, then to 20 mA and check the current through the loop. After the
test, replace the plug.
