With process control equipment disabled, enter the RUN mode to monitor system
performance and alarm programming. Otherwise, perform a Reading Measurement
simulation (P920).
When satisfied with system performance and programming:
•
connect a high alarm indicator to Relay #1 (see P100 = 4).
•
connect a low alarm indicator to Relay #2.
•
connect a high high alarm indicator and filling equipment stop/start control to Relay #3.
•
connect a low low alarm indicator to Relay # 4.
(Note that relays are de-energized in "power off" and "alarm" conditions).
For cement applications (or any very dusty dry solids), measurement difficulties
during vessel filling are common. For this example (assume the maximum filling rate),
failsafe operates as follows.
e.g.
09:15 am
Echo lost at 6.00 m, low alarm is still on, failsafe countdown begins.
09:17 am
Failsafe activated,
actual level = 6.16 m,
reported level = 6.00 m.
09:57 am
Low alarm off,
actual level = 9.36 m,
reported level = 10.00 m.
12:27 pm
High alarm on,
actual level = 21.36 m,
reported level = 25.00 m.
12:47 pm
Infeed stopped,
actual level = 22.96 m,
reported level = 27.00 m.
