Pressurized Line Liquid

Sampling System

For the Isco 5800 Refrigerated Sampler

Overview

The pressurized line sampling system for the Isco

5800 sampler consists of the sampler, a relay alarm box,

a 3-way actuated ball valve, an aluminum mounting

plate, and, if pressures will be in excess of 15 psi, a pres-

sure reduction valve. The system supports sampling

from pipes with pressures up to 300 psi. This is also

compatible with the 4700 Sampler.

Operation

A normal sample routine consists of the sampler

pumping first in reverse (pre-purge), then forward

(bottle fill), and reverse again (post-purge).

When the sampler runs forward, it sends a signal to

the relay alarm box (see the instructions under

Programming to activate this function). The alarm box

alerts the 3-way valve to allow pumping of the sample

liquid. During pre-purge and post-purge, the valve

causes the remaining liquid between itself and the sam-

pler to be discharged through the third port into the

user-supplied drain.

Pressures exceeding 15 psi must be reduced prior to

reaching the 3-way valve to maintain accurate sample

volumes and avoid damage to the system. Isco offers a

stainless-steel pressure reduction valve with 1/2" NPT

fittings.

Site Requirements

The discharge drain must be routed to a point at or

near zero pressure for complete purging and prevention

of cross-contamination between samples.

The Isco pressure reduction valve is not recom-

mended for sample sources containing solids, or with

viscosities higher than that of no. 2 oil. The user is

responsible for any pre-filtering required.

The Isco relay alarm box is an essential component

of this system. It is equipped with specific hardware, cir-

cuitry, and weatherproof enclosure not feasibly

duplicated in the field.

The system must be positioned near a mains outlet

that is easily accessible, so that power can be quickly

removed in the event of an emergency.

The line cord is the only disconnect device. Mains

power is applied to the system continually.

WARNING

If this equipment is used in a manner not specified

in the instructions, safety may be compromised.

Setup and Installation

Programming

When enabled, a software option causes the sampler

to delay the bottle fill and post-purge pumping steps by

10 seconds to allow the 3-way valve to fully open. This

option must be enabled for proper filling and purging

during pressurized sampling.

To enable the pump valve option:

1. Turn the sampler controller on. From the main

menu, select CONFIGURE.

2. At SELECT OPTION, arrow to OUTPUT PINS and

select.

3. Under SET OUTPUT 1, arrow to 3-WAY VALVE

CONTROL and select.

4. Continue programming output pins as needed,

and then select EXIT CONFIGURATION.

Plumbing and Positioning

Connect the drain to a point at or near zero pressure.

A 1/2" coupler is provided for connection to the sampler

and discharge line. It may be necessary to heat the

tubing in order to slip it over the coupler.

Connect the line from the pressurized source to the

3-way valve (or pressure reduction valve if used) with

the shortest possible length of tubing.

Note

A manual shut-off valve (user-supplied) is

recommended for placement between the sampling

system and the sample source for purposes of system

removal, should this become necessary.

Ensure that the sampler outlet is positioned higher

than its connection to the 3-way valve to ensure com-

plete purging.

CAUTION

Ensure that the user-supplied connecting hardware

between the liquid source and the system inlet can

safely withstand the maximum pressures of the source.

Pressure Reduction Valve

The pressure reduction valve (Figure 2) is required

for installations where pressures will exceed 15 psi. This

is a one-way valve designed to reduce liquid pressure

from up to 300 psi to a pressure adjustable between 3

and 30 psi. When used with Isco samplers, the pressure

should be adjusted for 8 to 10 psi.

Teledyne Isco is continually improving its products and reserves the right to change product

specifications, replacement parts, schematics, and instructions without notice.

The valve comes pre-adjusted from the factory. Field

adjustment is seldom required, if ever.

However, if adjustment should become necessary:

1. Loosen the lock nut located behind the pressure

dial (Figure 3).

2. Turn the adjustment bolt clockwise to increase

the valve’s pressure output, or counterclockwise

to decrease it.

3. If the pressure gauge does not read between 8

and 10 psi, repeat step 2.

Note

A sample cycle may be required for the gauge to

4. Tighten the lock nut to secure the adjustment

bolt.

Wiring

Standard systems come pre-wired and mounted on

the aluminum plate. For assistance with other types of

Isco alarm boxes, additional alarm outputs, and systems

that are not pre-wired, contact Teledyne Isco.

Connect the signal cable from the relay alarm box to

the 16-pin connector on the back side of the sampler

(see Figure 4).

Plug the line cord into the AC electrical outlet, and

the system is ready for use.

Cleaning

To clean the system, use a mild detergent in water.

For tougher stains, use isopropyl alcohol. If the installa-

tion location permits, the system may be hosed down.
