Set a Delayed Start

A delayed start can be programmed using the pump keypad or from a PC using DataTrac Software. The following

instructions are for keypad only. See DataTrac for Leland Legacy Operating Instructions (included on software CD) for

programming from a PC.

Once a program is set in the pump, the pump cannot be run manually. To return to manual pump operation, let the

program run its course or delete the program. See Delete a DataTrac Program or a Delayed Start.

When sett ing the pump for sampling from 1 to 99,999 minutes to begin within the next 12-hour period, follow this procedure:

1. Press [??], then press the security code ???? in sequence. Setup will display briefl y.

2. Press ? until the display reaches the 12 Hr/24 Hr clock. If delayed start is already programmed, the display will

show Dela (delayed start) in place of 12 Hr. If no delay is programmed, press ? or ? until the display shows a

fl ashing Dela (delayed start).

3. Press ? until the time of day (fl ashing hours) displays. Select the hour (time of day) that the pump is to begin

sampling (within the next 12 hours) by pressing ? or ? until the desired hour displays. Press ? and the minutes

will fl ash. Press ? or ? until the desired minutes display. Note: The time of day entered will be the next occurrence of

this time within the next 12-hour period after the delayed start is entered. There is no a.m. or p.m. designation.

4. Press ? until the ST displays. Press ? or ? to set the desired run time in minutes. A delayed start cannot be run unless a

sampling time (ST) is programmed.

5. Press ? until End appears.

6. Press [??] to save sett ings and exit Setup.

7. Prog and a fl ashing Hold will appear in the upper left corner of the display. The pump is now set for delayed

start.

Set Pump Flow Rate

1. Press [??], then press the security code ???? in sequence.

2. The fl ow rate and Set will fl ash on the LCD. Press ? to increase fl ow rate. Press ? to decrease fl ow rate. The

pump will run while fl ow is set.

3. Once the desired fl ow rate is displayed, press ? until End appears on the display. The pump will stop running.

4. Press [??] to save the new fl ow rate and exit Setup.

Flow Rate and Volume Display

? Flow Rate displayed on the pump LCD is the fl ow to which the pump has been calibrated. To maintain fl ow as displayed, the pump automatically

adjusts fl ow during sampling for changes in temperature and atmospheric pressure* that may differ from the temperature and atmospheric pressure

present at the time of calibration. The fl ow rate display does not change from the calibrated fl ow rate. The pump will fault if it is unable to maintain the

calibrated fl ow rate.

? Volume displayed on the pump LCD is “corrected” in that it is the result of a continual calculation of corrected fl ow rate multiplied by sample time.

Volume does not display after 99,999 liters. See Volume Display under Sampling Functions.

* The pump can apply correction to volumetric fl ow during sampling for weather-related or altitude variations from the atmospheric pressure established at calibration up to at least 7500 feet

above and 5000 feet below sea level.
