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).

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.

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.
