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

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.
