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.

12-A. From the Advanced Sampling menu highlight Program Complete using

the

UP and DOWN keys. Press SELECT to continue.

12-B. Enable or Disable Program Complete using the

CHANGE CHOICE key.

ACCEPT to continue to Set Point Sampling.

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.

13-A. Highlight Setpoint Sampling using the

UP and DOWN keys on the

Advanced Sampling Menu. Press

SELECT.

13-B. Enable or Disable Setpoint Sampling using the

CHANGE CHOICE key.

Press

ACCEPT to continue.
