Appendix C
Stormwater mode is not allowed when the sampler is
configured with one bottle.
The program cannot start: timed rinse required.
The program cannot start: the primary device is not properly
set up.
The program cannot start: volume calibration required.
The program setup needs flow to be logged at an
interval < or = the flow time limit.
The program setup needs rain to be logged at an interval < or =
the rainfall time limit.
The signal did not stabilize in time—calibration failed.
• 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.
The value must be: xxx—yyy
(xxx is minimum, yyy is maximum).
• This program stop is prior to the last program start.
• This program start is prior to the last program stop.
Timed bottle sets are not allowed unless distribution is
bottles-per-sample mode.
Timed bottle sets are not allowed when the sampler is
configured with one bottle.
Times cannot be more than 24 hours apart.
Too few bottles—review timed bottle sets, upset sampling, &
stormwater. Minimum needed:
Too many alarms and setpoints have been requested.
Too many samples-per-bottle for the bottle volume:
The sample volume is too large for the bottle volume:
Upset sampling is not allowed when the sampler is configured
with one bottle.

Troubleshooting and Error Messages
Tried to enable Storm Water with a single bottle.
Occurs if the liquid sensor is disabled and timed calibration
has not been performed for the rinse cycle.
If the operator goes partially through the flow meter setup
screens but stops before entering all necessary parameters.
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.
If an alarm, setpoint or stormwater uses flow rate-of-change
as a trip point.
If an alarm, setpoint or stormwater uses rainfall as a
trip point.
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.
When selecting the time/date for graphing and the selected
beginning or ending time falls outside the range of data.
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.
When entering start/stop times. Start/stop times must be
entered in chronological order.
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).
Tried to enable Timed Bottle Sets with a single bottle.
When selecting a start and stop time for a graph display the
limit (due to screen resolution) is 24 hours.
Occurs if there are not enough bottles to perform all the
various functions. Either install more bottles or decrease
number of programmed functions.
Occurs if more than 20 alarm and setpoint conditions are
set. Storm Water start conditions use one or two setpoints.
Occurs when the sample volume is checked, if the
requested sample volume is too big to fit in the bottle.
Tried to enable Upset Sampling with a single bottle.
