Advanced sampling choices:
Step 12 - Program complete output
Program Complete Output sends a +12 V dc signal out Pin F of the Auxiliary Receptacle
at the completion of the sampling program. This signal is also sent when a Full Bottle
condition causes the program to complete. The Program Complete signal remains on
(+12 V dc) for 61 seconds and then turns back off (0 V dc).
Program Complete Output is used for the following purposes:
•
Multiple Sampler Operation. Samplers are arranged in a “Cascade” control where the
first sampler signals a second sampler to start its program when the first sampler’s
program is complete. This feature requires the second sampler to be programmed for
external
start operation.
•
To interface to a PC to signal the end of the sampling program.
•
To interface to a relay that trips a signal light in a control room to indicate that sampling
is finished and samples are ready to be picked up.

Step 13 - Setpoint sampling
Setpoint sampling allows the control of an automatic liquid sampler from one of up to 14
sources. Setpoint sampling defines a set of limits that inhibit sampling until an upset
condition occurs, causing the limits to exceed. Sampling is enabled only when the waste
stream falls outside the setpoints.
