Bottle number
If the Program Complete Output is disabled, then it is used in conjunction with this
Special Output to transmit the bottle number to the connected device.
The Special Output signal can be configured to activate during one of the following
conditions:
•
After Each Sample– One second pulse at the completion of each sample cycle. It
signals an external datalogger or PC that a sample cycle was initiated. When this
choice is enabled, the sample success/failure is also transmitted to the external
datalogger by means of Pin F on the
Auxiliary connector.
•
Only When Pumping– During sample intake portion of cycle only, ignoring all purges
and rinse cycles. Used for tipping solenoid or ball valves when sampling from a
pressurized line.
•
From Rinse To Purge– During entire sample cycle, including all purge and rinse
cycles. Used for tripping solenoid or ball valves when sampling from a pressurized
line.
Step 15 - Start/stop times
Start/Stop Times start and stop a program at pre-arranged times. For example, this
feature can be used to run a program during weekdays and stop the program during
weekends, restarting on the following Monday. It can also halt sampling for nighttime
shutdowns.
Up to 12 Start and 12 Stop time entries can be set in any one program. Either a Start
Time and Date or a Start Time and Day of the Week may be selected.
