Volume
To program the unit for volume, set:
• operation (P001) to level 1 (see page 55)
• tank shape (P050) to a value other than 0 (see page 57)
• other volume parameters (P051 to P053) as required.
To program the unit for ullage, set:
• operation (P001) to space 2 (see page 55).
Fail-Safe
When the fail-safe timer (P070) expires, the mA output responds as follows:
Fail-safe Mode (071) Status (0/4 - 20) Status (20 - 0/4)
1 = high 22 0/2
2 = low 0/2 22
3 = hold hold hold
Run/Program
When the IQ Radar 300 changes from RUN
RUNRUN
RUN to PROGRAM
PROGRAMPROGRAM
PROGRAM, the unit no longer responds to
the process. The last measurement is stored and the associated readings and mA
output are held.
The unit reverts to the parameter last addressed during the previous program session.
Upon return to RUN
RUNRUN
RUN, the transceiver resumes operation. The reading and mA output
default to the last measurement taken. The reading and associated outputs migrate to
the current process level at a rate controlled by the measurement response (P003).
