Chemical or biological hazards. If this instrument is used to monitor a

treatment process and/or chemical feed system for which there are

regulatory limits and monitoring requirements related to public health,

public safety, food or beverage manufacture or processing, it is the

responsibility of the user of this instrument to know and abide by any

applicable regulation and to have sufficient and appropriate

mechanisms in place for compliance with applicable regulations in the

event of malfunction of the instrument.

The A1000 and A1000XP TOC analyzers use UV light to oxidize water

samples for TOC analysis in pure and ultra-pure water for the semi-

conductor industry. Refer to Figure 1 and Figure 2. No reagents or gases

are used in the process. The conductivity of each sample (in ppb) is

measured two times, once before and once after sample oxidation by

ultraviolet (UV) light.

An integral alarm scheme reports any abnormalities found during the

analyzer operation. A TOC limit excursion is automatically sent to a

printer and shown on the display of the connected C80 controller.

The analyzers are used with the C80 controller for data collection and

operation. Refer to Figure 3 and User interface on page 20. More

analyzers and C80 controllers can be connected to make a local area

network. Multiple analyzers can be connected to one C80 controller to

monitor several process points from one location. As an alternative,

multiple controllers can be connected to show analyzer readings at many

locations.

Connect the DAC modules (optional)

Connect two DAC (digital-to-analog conversion) modules to the analyzer

with the two serial cables supplied with the DAC modules (four-

conductor serial cable, AWG 28). The DAC modules transmit the

resistivity and temperature values as 0–20 mA or 4–20 mA outputs.

Remove the serial connectors from the two serial cables. Then, connect

the serial cables to the DAC modules, Diagnostics connector and Bias

connector as shown in Figure 11. The DAC modules can be a maximum

of 16.7 m (50 ft) from the analyzer.

For the A1000 S20P and A1000XP, the attached printer is connected to

the Bias connector. Connect the DAC modules to an external +12 VDC

power supply instead of the Bias connector.

The Diagnostics connector is an RS232C series interface, 1200 baud

and 8 data bits (1 stop bit, no parity).

1 DAC 1 2 DAC 2

Connect the digital inputs (optional)

Connect a remote device and/or a switch to the Inputs connector on the

I/O connector block. The Inputs connector has two digital inputs. Refer to

Table 1.

The two digital inputs share a common positive terminal. Use an external

5–30 VDC power source or the 12 VDC bias output on the I/O connector

block to supply power to the digital inputs. Refer to Figure 12. Each

digital input draws 1–14 mA, depending on the applied voltage. The

digital inputs operate from open collector, open drain or relay outputs.

Connect the analog output (optional)

One 0–20 mA or 4–20 mA analog output is available at the 4–20 mA

connector on the I/O connector block. The analog output signal is

proportional to the last TOC reading. The analog output range and its

corresponding TOC zero-scale and full-scale values are the same as the

selected DAC TOC zero-scale and full-scale values. If a critical error

occurs during a TOC analysis, the analog output goes to the selected

DAC error output state.

Connect a current receiving device to the 4–20 mA connector on the I/O

connector block. Refer to Figure 14.

To connect a voltage receiving device instead, convert the analog output

signal to a voltage output with a resistor as shown in Table 4. The

analog output drives resistance between 50 and 500 ohms, including the

interconnecting cables. The precision of the resistor directly affects the

accuracy of the data. A 1% wire-wound resistor or better is

recommended. For maximum data integrity, make sure that the resistor

is installed across the input terminals of the receiving device.

Tighten a new ferrule 1¼ turns the first time it is tightened. Then, only tighten the

ferrule 1/8 turn to make a connection. Do not tighten the fittings more as this may

cause damage to the fittings or ferrules and cause leaks.

Items to collect:

• 3/4-in. open-end wrench

• 9/16-in. open-end wrench

A1000—Do not use the supplied PFA tubing for installations when the

sample is:

• More than 75 °C (167 °F) and more than 620 kPa (90 psig)

• More than 85 °C (185 °F) and more than 550 kPa (80 psig)

For these installations, or for any application where the use of PFA

tubing is a concern, use high-grade ¼-in. (OD) PTFE, FEP, PVDF or

316 stainless steel sample tubing instead.

A1000XP—Do not use the supplied PFA tubing. The A1000XP analyzer

is designed for the purest water systems so use non-permeable tubing,

such as Kynar

®

or 316L electro-polished stainless steel for the sample

tubing. Teflon

™

PFA/PTFE can be used, but there is a potential for

sample corruption due to the permeability of the tubing. Keep the

distance between the sample point and the analyzer as short as

possible.

1. Plumb the sample tubing. Refer to Figure 17.

2. When the sample is more than 50 °C (122 °F), install a heat

exchanger in the sample line upstream of the analyzer or erratic

readings will occur. The heat exchanger is supplied by the user.

Install an isolation valve

Install an upstream isolation valve near the analyzer so the sample flow

to the analyzer can be controlled manually. The isolation valve is

supplied by the user.

Exception: For the A1000XP analyzer, the manufacturer recommends

that no isolation valve be installed in the sample line to minimize the

potential for contamination. If an isolation valve is necessary, clean the

isolation valve thoroughly of all lubrication and other debris before

installation.

1. Open and close the isolation valve several times before it is

connected to the analyzer to flush debris from the system.

2. Use the supplied ¼-in. tube x ¼-in. MNPT compression fitting as

necessary to connect the isolation valve to the analyzer. Refer to

Figure 18.

Plumb the drain

D A N G E R

Potential Electrical shock and fire hazards. The drain line must be

connected to a drain system that is at ambient pressure.

N O T I C E

Tighten a new ferrule 1¼ turns the first time it is tightened. Then, only tighten the

ferrule 1/8 turn to make a connection. Do not tighten the fittings more as this may

cause damage to the fittings or ferrules and cause leaks.

Items to collect:

• 3/4-in. open-end wrench

• 9/16-in. open-end wrench

1. Plumb the drain tubing to the drain (WATER OUT) port. Refer to

Figure 17 on page 19.

2. Connect the other end of the drain tubing to a drain system that is at

ambient pressure. Do not connect the drain line to another line to

prevent backpressure and damage to the analyzer.

Do a leak test

N O T I C E

Tighten the ferrule only another 1/8 turn to stop a leak. Do not tighten the fittings

more as this may cause damage to the fittings or ferrules and cause leaks.

1. Slowly open the upstream isolation valve to let water flow to the

analyzer.

2. Open and close the upstream isolation valve several times.

3. Examine the plumbing connections for leaks.

4. If a leak is found, slowly tighten the compression fittings to stop the

leak.

User interface and navigation

User interface

Figure 19 shows the controller display, LEDs and keypad. The controller

is a stand-alone unit or an integral component of the analyzer. Table 5

gives the function of each key on the keypad.

The eight channel LEDs show the alarm status of the analyzers

connected to the controller. When the controller identifies that an alarm

has occurred on an analyzer, the channel LED for the analyzer changes

from green to red and starts flashing.
