Part 3 Sensor Mounting

3.1 General
Select a location within the maximum sensor cable length (30 ft) for mounting of the sensor flow cell. If
there is more than 30 ft distance from the electrode to the transmitter, you should purchase a battery-
powered preamplifier model PHAMP-1, or use an amplified pH or ORP electrode. Locate sensor away from
pumps, adjustable frequency drive systems, or other sources of high frequency EMI if possible. Refer to the
installation manual for your electrode for mounting requirements.

 PRODUCT INSTRUCTION MANUAL

Part 4 Transmitter Electrical Installation

4.1 General
The TX100 loop-powered instrument is a 12-24 VDC loop-powered pH/mV transmitter.

WARNING: Do not connect AC line power to the 2-wire module. Severe damage will result.

Important Notes:
1. Use wiring practices that conform to all national, state, and local electrical codes.
2. DO NOT run sensor cables or instrument 4-20 mA output wiring in the same conduit that contains AC
power wiring. AC power wiring should be run in a dedicated conduit to prevent electrical noise from
coupling with the instrumentation signals.
3. DO NOT remove dessicant pack from inside transmitter case. This is necessary to control moisture.

4.2 Power
A12-24VDC power supply, eight amp maximum current must be used to power the instrument. See chart
below for Maximum load. The exact connection of this power supply is dependent on the control sys-
tem into which the instrument will connect. See Figure 4.1 for further details. Any twisted pair shielded
cable can be used for connection of the instrument to the power supply. Route signal cable away from AC
power lines, adjustable frequency drives, motors, or other noisy electrical signal lines. Do not run sensor or
signal cables in conduit that contains AC power lines or motor leads. The TX100 is supplied with a light-
ning protective component.

Note: Terminal block labels for power, electrode and temperature sensor connections are marked on the PCB next to their
respective terminal.

Part 5 Electrode Electrical Connection

5.1 General
The electrode cable can be quickly connected to the TX100’s terminal strip by matching the wire colors on
the cable conductors. Route signal cable away from AC power lines, adjustable frequency drives, motors, or
other noisy electrical signal lines. Do not run sensor or signal cables in conduit that contains AC power lines
or motor leads.

5.2 Direct Sensor Connection

The sensor cable can be routed into the enclosure through one of the provided cord-grip retainers, or
through a properly sized conduit connection. Connect electrode wires as shown below.
If the cord-grip devices are used for sealing the cable, ensure the cord-grips are snugly tightened after elec-
trical connections have been made to prevent moisture incursion.

Note: Terminal block labels for power, electrode and temperature sensor connections are marked on the PCB
next to their respective terminal.

Part 8 Calibration
8.1 Getting Started
Before pH and temperature calibration is possible, some preparation is necessary. First, make sure you are in
the proper measurement mode. The measurement mode is shown on the display in the upper right corner
“pH” for pH and “mV” for ORP or other mV sensors.

Ensure the sensor is connected to the transmitter as shown in Part 5.1.

Always use fresh buffer solutions when calibrating. Check expiration date on buffer package.

If possible, use deionized water to rinse electrode before calibration and between buffers.

For temperature calibration, make sure the temperature sensor wires are connected as shown in FIG 5.1. If
no temperature sensor is connected, the transmitter will default to read 25.0 degrees C or 77.0 degrees F.

8.2 2-Point pH Calibration

The TX100 performs two-point calibrations using preprogrammed buffer choices. No mV calibration is re-
quired. See Figure 8.1 for calibration programming.

Part 10 Troubleshooting
10.1 General
The information included in this section is intended to be used to quickly resolve an operational problem
with the system. During any troubleshooting process, it will save time if the operator can first determine if
the problem is related to the transmitter, electrode, or some external source. Therefore, this section is orga-
nized from the approach of excluding any likely external sources, isolating the transmitter, and finally isolat-
ing the electrode. If these procedures still do not resolve the operational problems, any results noted here
will be very helpful when discussing the problem with the factory technical support group.

10.2 Troubleshooting Guidelines

To begin this process, review the connections of the system to all external connections:
1. Verify the proper power input is present (12-24V DC, 8 amp maximum). Ensure the loads on the
4-20 mA outputs do not exceed the limit (See Section 4.2) .
2. Do not run sensor cables or analog output wiring in the same conduits as power wiring. If low
voltage signal cables must come near power wiring, cross them at 90° to minimize coupling.
3. Check for possible ground loops. High frequency sources of electrical noise may still cause erratic
behavior in extreme conditions. If readings are very erratic after wiring has been checked, check
for a possible AC ground loop by temporarily moving the sensor to a sample of solution in a
beaker or other container.

Part 11 Maintenance

11.1 Overview
The TX100 pH/mV transmitter needs little routine maintenance. The calibration of the transmitter should be
checked periodically. To recalibrate the TX100 and electrode, see Part 8.
