4.5.2 APU warning code (item WC), error code (item EE) and status request
(item QR) of ICU board
Some ICU (APU part) warning codes of item
WC
(indexed item of 10 elements) are listed below, with
suggestions for solving the problem. For a complete overview, refer to item help in the service tool Ensite.
00000 No warning
07000 Low product reflection No product reflection above threshold; check with a reflection diagram
and lower threshold value in item ZP if possible
07001 Sensor contaminated Clean the antenna
07005 Top / bottom clipping in raw samples A-channel Lower A-channel gain in item 5O, or enable automatic amplification
07006 Top clipping raw samples A-channel control item 4M
07007 Bottom clipping raw samples A-channel
07013 Level above measuring range Level measured with reduced accuracy and close to antenna!
07014 Ambiguous init situation Select first peak or select second peak command has been issued.
Warning code disappears after peak detection routine has detected a
certain (valid) level change.
07200 Reduced accuracy Not enough points in table or level too close to antenna (within 4 m) for
AdvancedDSP level calculation. This is automatically corrected when
level in tank changes.
07201 A-channel measurement error after start-up This will be solved when the level in the tank reaches the reference
level, or when a new RL level is entered, followed by the AR command
Some ICU (APU part) error codes of item
EE
(indexed item of 10 elements) are listed below, with
suggestions for solving the problem. For a complete overview, refer to item help in the service tool Ensite.
00000 No errors encountered
07014 Ambiguous init situation Select first peak (item 4W) or select second peak (item 4X), after
verification of level by means of manual measurement
07101 Antenna zone out of range The antenna and bottom zone may not overlap; check items AZ and BZ
07102 Antenna zone end before begin Check sign of item AZ (should not be negative)
07103 Antenna zone threshold out of range Item ZA must be between 0 and 90 dB
07104 Product zone threshold out of range Item ZP must be between 0 and 90 dB
07106 Start bottom zone after bottom end Bottom zone (item BZ) must be within measuring range (40 metres).
Check also item PR
07107 Bottom zone threshold out of range Item ZB must be between 0 and 90 dB
07108 Obstruction zone start out of range Obstruction zone start and end must be within measuring range
07109 Obstruction zone end out of range (40 metres). Check also item PR
07110 Obstruction zone position switch Define obstruction zones in consecutive order
07112 Obstruction zone threshold out of range Item OT
.n.i
must be between 0 and 90 dB
07113 Short measuring range Antenna zone (item AZ) and bottom zone (item BZ) may not overlap
07170 Stilling well diameter out of range Item BD must be between +0.0440 and +0.3353 metres range
07172 Operation mode unknown Item OM must be either ‘F’ or ‘S’
07173 Antenna mode / Operation mode conflict Wrong type of antenna used (i.e. stilling well antenna on a free space
SmartRadar LT)
07901 Maximum safe fill (item SF) exceeded Item SF must not be zero and not exceed the range (PR - AU)
18001 Relay error Check item AX, or replace ICU board
21003 Ullage correction table error Check item CL; each level may only be entered once
21004 Verification pin table error Check items PB and PC (must be entered in ascending order)
