P-74 fail-safe mode
in the event of a loss of echo, the MultiRanger Plus will flash " LOE "
and go into one of the following fail-safe modes after the timer
( P-75 ) expires
enter: 1 = high
2 = low
3 = hold last entry ( F )
P-75 fail-safe timer
the amount of time delay before going into fail-safe mode enter
" desired amount of time ", in minutes ( F = 15.00 )
e.g. for 30 sec. time delay, enter " 0.5 "
Parameter P-76 through P-78 are used for measurement and simulation.
DISPLAY:
select desired parameter
P-76, 77 or 78 press , the display will show the reading of the last
ultrasonic measurement
press to update ultrasonic measurement
SIMULATION:
select desired parameter
P-76, 77 or 78 press , the display will show the simulated rise and
fall of the material level
The simulation will raise and lower the material level through the
calibrated span, P-4, at a rate of 1% of the span per second. On the
DLD application, one side ( relay / LED 5 ON ) is kept at a constant
level, while the other side ( relay / LED 5 OFF ) is varied. The DLD
simulation will alternate every 6 seconds.
