FLOW
mode it will display

and totalization will stop until an echo is
received. Refer to ECHO STRENGTH instructions.
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 PZ12 sensors.
Minimum Range for PZ32T sensors must be greater than or equal to
12"/30.5 cm and for optional PZ52T 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 than102 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 ½ 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).
