Metex 3200U Ultrasonic Flow & Level Monitor - Manual (Page 24)

ERROR/WARNING MESSAGES
! LOSING ECHO ! No valid echoes for half LOE TIME ( SPECIAL FUNCTION menu).
"ECHO LOSS" (flashing) No valid echoes received within the LOE TIME setting. See FIELD
TROUBLESHOOTING (F). In Level mode the Ultrason will hold the
display and outputs at the last reading until a new echo is received. In
FLOW mode it will display 0.00 and totalization will stop until an echo
is received.
Er: ILLEGAL MinRg The value entered for MinRg (Minimum Range) is less than 8"(20.3 cm).
MinRg must be greater than or equal to 8" (20.3 cm) for US12-1A1A
sensors. Minimum Range for US2-1A1A sensors must be
³ 12" / 30.5
cm and for optional US2-2A1B sensor must be greater than or equal to
16" (40.6 cm).
Er: ILLEGAL UNITS Your choice of UNITS exceeds a maximum value of 9,999,999. Use US
MGD, Imp MGD or m3/d so that UNITS will be 9,999,999 or less.
Err:ILLEGAL SPAN 1. The value entered for MaxRg is the same or less than MinRg +2".
Maximum range must be greater than minimum range and less than
102 ft. (31.09 m). (Note: to invert the scale and outputs, choose
Level instead of Range selection in the UNITS/MODE menu.)
2. For Rectangular Weirs with End Contractions, the SPAN ( MaxRg -
MinRg ) must be less than 1/2 the weir size (eg: 12" crest width,
SPAN must be 6" or less).
- or - Your choice of Units exceeds 9,999,999. Use USMG/d
,
IMG/d or m3/d
so that Units will be 9,999,999 or less
ERR: ILLEGAL
SETPOINTS
ON or OFF setpoint is < MinRg or > MaxRg
NORMAL / REVERSED
SET POINTS MIXED!
Relays have been selected for Pump Alternation and have been calibrated
in opposite modes. Any alternating relays must be calibrated in the same
mode:
1. with ON setpoint > OFF setpoint, or
2. with OFF setpoint > ON setpoint
TEMP * 23.5 C * Indicates Temperature Compensation fault. Check sensor connections.
ECHO TOO CLOSE Indicates that the target is less than MinRg distance from the sensor
(too close to the sensor)
!! SENSOR OPEN ! Instrument has detected sensor connection/cable Open.
! SENSOR SHORTED ! Instrument has detected sensor connection/cable Shorted.
