Appendix C
Stormwater mode is not allowed when the sampler is
configured with one bottle.
Tried to enable Storm Water with a single bottle.
The program cannot start: timed rinse required.
Occurs if the liquid sensor is disabled and timed calibration
has not been performed for the rinse cycle.
The program cannot start: the primary device is not properly
set up. If the operator goes partially through the flow meter setup
screens but stops before entering all necessary parameters.
The program cannot start: volume calibration required.
If the liquid sensor is disabled and timed calibration has not
been performed for the main sample, the first flush or the
upset sample volume.
The program setup needs flow to be logged at an
interval < or = the flow time limit. If an alarm, setpoint or stormwater uses flow rate-of-change
as a trip point.
The program setup needs rain to be logged at an interval < or =
the rainfall time limit. If an alarm, setpoint or stormwater uses rainfall as a
trip point.
The signal did not stabilize in time—calibration failed.
When calibrating pH, process temperature, ORP, D.O., D.O.
temperature, conductivity, or conductivity temperature, the
signal from the probe did not respond within the calibration
time limits. Replace buffer solutions (if applicable) or try
another probe.
• The time entered is before the first logged value. Data will
be display from beginning.
• The time entered is after the last logged value. Data will be
displayed from the end.
When selecting the time/date for graphing and the selected
beginning or ending time falls outside the range of data.
The value must be: xxx—yyy
(xxx is minimum, yyy is maximum).
The value entered was out of the legal range, when
changing any numeric parameter. The appropriate range is
always displayed on the bottom line on the entry screen.
• This program stop is prior to the last program start.
• This program start is prior to the last program stop.
When entering start/stop times. Start/stop times must be
entered in chronological order.
Timed bottle sets are not allowed unless distribution is
bottles-per-sample mode.
Tried to enable Timed Bottle Sets when bottles per sample
have not been specified (the bottles-per-sample is used as
the bottle set quantity).
Timed bottle sets are not allowed when the sampler is
configured with one bottle.
Tried to enable Timed Bottle Sets with a single bottle.
Times cannot be more than 24 hours apart.
When selecting a start and stop time for a graph display the
limit (due to screen resolution) is 24 hours.
Too few bottles—review timed bottle sets, upset sampling, &
stormwater. Minimum needed:
Occurs if there are not enough bottles to perform all the
various functions. Either install more bottles or decrease
number of programmed functions.
Too many alarms and setpoints have been requested.
Occurs if more than 20 alarm and setpoint conditions are
set. Storm Water start conditions use one or two setpoints.
Too many samples-per-bottle for the bottle volume:
The sample volume is too large for the bottle volume:
Occurs when the sample volume is checked, if the
requested sample volume is too big to fit in the bottle.
Upset sampling is not allowed when the sampler is configured
with one bottle.
Tried to enable Upset Sampling with a single bottle.
