Connect the DAC modules (optional)
Figure 11 DAC module wiring
Connect two DAC (digital-to-analog conversion) modules to the analyzer
with the two serial cables supplied with the DAC modules (fourconductor serial cable, AWG 28). The DAC modules transmit the
resistivity and temperature values as 0–20 mA or 4–20 mA outputs.
Refer to Analog setup on page 30 for DAC configuration information.
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. Refer to Digital inputs and outputs on page 31 for more
information.
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.

Figure 14 Analog output wiring
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. Refer to Analog
setup on page 30. 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.

The most common analyzer fault condition is an analyzer that measures
a TOC value larger than its specified TOC Alarm setting. Refer to Set up
the alarm on page 31.
There are several ways a TOC limit excursion alarm condition is
reported:
•
•
•
•
The associated controller LCD display flashes.
The analyzer channel LED flashes red.
If enabled, the controller beeps an audible alarm.
If connected to a printer, a printout is generated documenting the
fault. A High TOC Alarm Warning is shown on a separate line and
includes the limit that was exceeded.
• When connected, the signal at the analyzer digital output #1 port is
pulled low. Refer to Digital inputs and outputs on page 31.
For information on how error alarms are reported, refer to Alarms
on page 39.
Uncompensated conductivity alarms (A1000 models)
Alarms are reported for conductivity limit excursions when
Uncompensated is selected for conductivity units. Refer to Select the
units on page 28.
32 English
The actual (uncompensated) conductivity limits are in accordance with
the specifications set forth in the method “<645> Water Conductivity” of
the U.S.A. These temperature-based limits are shown in Table 7.
When the reading is more than the uncompensated limit, an alarm is
triggered and several things occur:
• The LED corresponding to the analyzer Channel ID flashes red on all
of the associated controllers.
• The alarm is logged and can be shown on any of those controllers.
• If the analyzer is attached to a local printer, a hard copy of the
condition is supplied and contains the time of the excursion, the
measured conductivity and temperature and the USP conductivity limit
exceeded.

Troubleshooting
Alarms
Functional range and logic checks are continuously monitored to identify
the functional status of each analyzer during every analysis. When one
or more alarms occur, the controller display flashes and the channel LED
for the analyzer changes from green to red and flashes. The analyzer
will always try to recover and continue analysis.
Note: If an alarm occurs during a diagnostic test, the analyzer will not try to take
another measurement until the displayed alarm is acknowledged. After the problem
has been corrected, start the diagnostic test again as necessary.
If a printer is connected to the analyzer, any problems identified during
operation are supplied as a hard copy report. Each analyzer keeps an
alarm log. The alarm log includes the:
• Code number of each alarm
• Number of occurrences of each alarm
• Time of the initial occurrence of each alarm
The alarm log is erased whenever power is removed from the instrument
or when the ME command is sent with a serial device. Refer to Mode set
commands on page 45.
analyzer, a hard copy report of the alarm log entries can be made. Refer
to Send the parameters or log entries to the printer on page 27.
The alarm codes identify hardware or water chemistry problems.
Hardware alarms (Codes 1–99) identify an electromechanical or
analytical failure of the analyzer (e.g., an expired UV lamp, a faulty
solenoid valve or a hardware malfunction). Refer to Table 9 and

Code 35
42 English
The sample valve has a blockage or a UV lamp failure has
occurred. Backflush the sample valve. Refer to Backflush the
sample valve on page 42. Replace the UV lamp if necessary.
Backflush the sample valve
Backflush the sample valve when the sample plumbing has a blockage
or there is unwanted material in the plumbing that does not let the
sample valve fully close. A backflush removes unwanted material from
the plumbing and cleans the analyzer water filters.
If the problem is still present after the analyzer has been backflushed,
send the analyzer to the manufacturer for service.
Symptoms of a blockage are:
• The amount of sample flow through the analyzer is less than normal.
A corresponding drop in TOC and/or resistivity readings occurs
because the water sample is not sufficiently replaced in the
measurement cell.
• The water sample continues to flow when the analyzer is off even
though the Valve at Idle setting is set to Closed or during the oxidation
stage of analysis. Even a very small amount of flow will cause the
TOC reading to change.
Items to collect:
• 9/16-in. open-end wrench
• 3/4-in. open-end wrench
1. Close the upstream isolation valve to stop water flow to the analyzer.
2. Disconnect both the water inlet and the drain tubing from the
analyzer. Hold the bulkhead fitting with the 3/4-in. wrench. Loosen
the compression fittings with the 9/16-in. wrench.
3. Change the sample flow direction through the analyzer. Plumb the
drain tubing to the sample inlet (WATER IN) port. Plumb the sample
tubing to the drain (WATER OUT) port.
4. Open the upstream isolation valve to let water flow to the analyzer.
5. Put the analyzer in Purge mode. Refer to Select the operating mode
on page 26.
6. After 30 seconds, put the analyzer in Auto TOC mode, then back to
Purge mode 30 seconds later.
7. Do step 6 several times to open and close the sample valve. As an
alternative, use the Valve Test to open and close the sample valve
manually. Refer to Diagnostic tests on page 43.
8. Do steps 1–2 again.
9. Plumb the drain tubing to the drain (WATER OUT) port. Plumb the
sample tubing to the sample inlet (WATER IN) port.
10. Open the upstream isolation valve to let water flow to the analyzer.
Diagnostic tests
Use the diagnostic test(s) to identify the source of an analyzer alarm.
The results of a diagnostic test are shown on the display and sent to the
attached printer. If a diagnostics test fails, contact technical support.
Note: Cell tests cancel the current analysis cycle. Analysis automatically starts
again when a cell test stops.
3. To do an electronics test, select Electronics, then select the test.

The analyzer has a bidirectional serial interface that lets it communicate
with many different types of devices, such as a programmable logic
controller (PLC) or a host computer. The wiring is configured as for any
PC-compatible RS232C serial interface.
Analyzer command set
The serial interface commands include mode set, parameter set, data
read and log functions. The commands can be upper or lower case and
include:
• Two-character ASCII text mnemonics, or
• One or more arguments and then a command mnemonic
Each argument is separated by at least one space (ASCII 32; 20 Hex).
Identify the end of each command string with a carriage return (ASCII
13; 0D Hex).
The analyzer shows “OK>” after a command is accepted. When a data
read or parameter set command is accepted, the analyzer also shows
one or more numeric or text values. Each value is separated by at least
one space (ASCII 13, 10; 0D, 0A Hex).
Both the commands and the messages shown on the display use a “free
field” format, so the number of delimiting spaces and the length of each
argument or data field may be different.
Note: If a command is rejected (e.g., invalid syntax), a "?" (ASCII63; 3F Hex) is
shown before the “OK>”.
Table 12 shows the notation used for each command argument.
