    CURRENT TIME: 07:49:32 1/10/25 4.3 Sampler Inhibit Before the GLS takes its first sample, it checks the inhibit line of the Flow Meter connector. If the GLS detects a logic low (grounded) level, it will suspend the program until the external device returns the line to a logic high (or open) level.

  • Page 38: Run State Displays

    Note The GLS will not “store” samples while it is inhibited. The GLS takes no action at all when it counts down a complete time or flow-pacing interval.

    If the GLS is in the Continuous Sampling mode, it only displays the next sample number. Errors – If the GLS encounters an error while running a program, the fol- lowing display alternates with the pacing interval countdown display:...

  • Page 40: Pausing Or Stopping A Program

    If the liquid detector finds that this excess amount of liquid is being returned through the liquid path, the GLS stops the program and indicates that the bottle is full. The duration of the post-purge is automatically calculated by the GLS based on the programmed suction line settings.

  • Page 41: Recovering The Sampler

    • A GLS with battery, full sample bottle, and ice may weigh as much as 63 pounds (28.6 kg). • The GLS must be kept level to avoid spilling the bottle’s contents. To prepare a full bottle to return to the lab you must first gain 4.8.2 Preparing the Full...

    The 2 gallon (7.6 liter) ProPak™ system was developed by Teledyne ISCO to offer the greatest convenience in preparing sample containers for re-use. Simply remove the used liner and place a new one in the holder. Used ProPak liners can be disposed of or recycled.

  • Page 47: Replacing The Pump Tube

    Check the condition of the pump tube regularly and if the tube shows signs of fatigue or wear, replace it immediately. A properly maintained sampler will pro- vide the years of reliable service that is expected of a Teledyne ISCO Sampler. WARNING Pump may actuate without warning.

    6. Clean the inside of the pump housing if necessary. Note Teledyne ISCO replacement pump tubes are marked with two black bands. These bands are used to correctly locate the tub- ing in the liquid detector and the pump. Position the pump inlet, or short end, in the upper groove of the liquid detector.

  • Page 49: Replacing The Discharge Tube

    Note The peristaltic pump and tube will perform the best when you: – Use Teledyne ISCO replacement pump tubes or bulk tubing. – Install the tube properly, aligning the inside edges of the bands with the outside edges of the liquid detector.

    The most significant effect is the sample volume accuracy. Although you can calibrate the sample volumes at a fixed suction head, the GLS will be unable to compensate for varying stream levels. Secondly, the GLS will not be able to detect a full bottle.
