Wiring Precautions
WARNING
Do not perform wiring work with wet hands. Doing so may cause an electric shock.
Before starting wiring work, be sure to dry your hands or use appropriate gloves, and turn off the
power. Failure to do so may cause an electric shock.
CAUTION
Perform wiring work correctly while carefully checking the specifications. Incorrect wiring may damage
the device or cause a malfunction.
Apply power correctly according to the specifications. If the power input is not according to
specifications, the device may be damaged.
Maintenance Precautions
WARNING
If signs of corrosion are found on a pressure-resistant part such as a bolt, nut, or flange, replace the
affected part with a new one. Otherwise, the part's performance may be compromised, resulting in a
dangerous situation. A damaged part may cause a cut or other injury.
CAUTION
When moving the probe up or down, move it slowly while carefully checking the surroundings, and
bundle and secure excess cabling. Failure to do so may cause cables to be caught, or objects to be
measured may be knocked out of position.
When work is performed with the probe in an upright position, be sure to secure it firmly. Failure to
do so may cause a personal injury or damage to the product.
Replace a damaged seal gasket or O-ring with a new one. If this product is operated with a damaged
seal, it may malfunction.
Do not attempt to modify or disassemble this product in any way that is not described in this manual.
Doing so may cause an electric shock or a malfunction.
When this product is no longer needed, dispose of it appropriately as industrial waste in accordance
with the applicable local regulations. Additionally, do not reuse a part or all of this product.
Do not open the case of the junction box in strong wind or rain. Water entering the junction box can
cause a malfunction.
Do not use SFN communication when the process measured by the liquid level transmitter is under
automatic control. Doing so may cause the output to vary, resulting in hazardous operation.

Chapter 2 Function and Configuration
Overview
The ALTJ9000 immersion type liquid level transmitter incorporates a microprocessor,
uses a semiconductor pressure sensor to detect the water pressure, and outputs the cur-
rent signal in proportion to the liquid level. This transmitter is composed of a probe and a
junction box. The probe, which is installed underwater, is connected to the above-ground
junction box by the hollow cable. The hollow cable contains a pipe with an inside diameter
of 3 mm so that the output does not change due to variations in atmospheric pressure.
Additionally, various settings of the liquid-level transmitter (range, damping time con-
stant, constant current output, etc.) can be changed and set from the control room using
a CommStaff communicator. Please also refer to the user's manual for the communicator
listed below as a reference document for this liquid level transmitter.

Configuration
yProbe
The probe, which consists of a pressure-receiving section and a transmission section, is
installed underwater. The water pressure is transmitted to a semiconductor pressure sensor
through a metallic diaphragm and sealed liquid. The transmission section processes the
output of the semiconductor pressure sensor. It converts the output to a 4–20 mA DC
signal in proportion to the liquid level, and then outputs the converted signal. The probe is
equipped with a lightning arrestor as standard equipment. Additionally, an approximately
6 kg weight and chain can be mounted easily as optional specifications.
yJunction Box
The junction box is installed above ground and connects to the hollow cable from the
probe and to the cable from the power supply. The reference pressure side of the semicon-
ductor pressure sensor is open to the atmosphere through the pipe of the hollow cable and
the hole in the rear panel of the junction box. The output can be indicated using an analog
meter. The junction box is also equipped with a lightning arrestor as standard equipment.

Chapter 2 Function and Configuration
Operating Principle
The pressure-receiving section transmits the water pressure through the metallic dia-
phragm and sealed liquid to the sensor section. In the sensor section, the sensor deforms
to a degree that corresponds to the transmitted pressure, and the resistance value changes.
A Wheatstone bridge circuit detects the resistance and sends it to the transmission section
after A-D conversion. At the same time, the auxiliary sensor (temperature sensor), which is
built onto the sensor chip, detects the ambient temperature and sends it to the transmission
section. The digitalized signal that has been sent to the transmission section is processed
by a microprocessor to convert it into a 4–20 mA DC analog signal proportional to the set
range using D-A conversion. After that, the converted signal is output. All of the pressure
and temperature data for the probe is obtained during manufacturing. In order to do the
calculations necessary to correct the measured pressure to the true pressure, this data is
stored in EEPROM. The microprocessor uses the information in EEPROM and outputs the
result.

Chapter 3 Installation
WARNING
Be sure to hold the chain when installing the product with the weight attached. Do not hold the
hollow cable, since it is slippery and holding it may cause an accident.
Only specialists should do the installation and wiring work. Otherwise a fire or electric shock may result.
"Specialists" are those who are skilled in instrumentation and electrical work.
CAUTION
After installing this product, do not use it as a scaffold or put your weight on it. Doing so may damage
the product.
Do not install the probe in a location where the water current is strong or where there is vibration.
Doing so may cause an output error.
Probe
yInstall the probe in a location where the water temperature is -5 to +55 °C and changes
in water temperature are minimized to as great a degree as possible.
yDo not install the probe in a location where the water current is strong or where there
is vibration.
yIf the weight is not attached to the probe, suspend the probe in the water. To prevent the probe
from swinging, suspend the probe inside a protective pipe to as great a degree as possible.
yIf the weight is attached to the probe, be sure to hold it by the chain and lower it gently
to the bottom of the water. If the probe is held by the hollow cable as it is lowered, the
wire may break or water may enter the probe. Therefore, never hold the hollow cable
when the probe is suspended.
yIf the weight is attached to the probe, select a level surface with a flat bottom. If the
probe is tilted, an output error may occur.
yWhen using a cable-retaining flange, tighten the gland, compress the gasket, and fix the
hollow cable. (Fig. 3-1)
yThe bend radius of the hollow cable is 30 cm. Do not bend it to a smaller radius.

Chapter 3 Installation
Junction box
yInstall the junction box in a location with an ambient temperature ranging from -5 to +55 °C.
yIf the junction box is installed in a poor atmosphere with high chlorine gas concen-
tration or high humidity, a contact failure or wire break may occur due to corrosion.
Therefore, please avoid such environments.
yThere is a rear cap on the rear panel of the junction box. The reference pressure is taken
from the hole in the rear cap through the tube of the hollow cable. Therefore, if water
enters the hole or if the hole is blocked, an output error or malfunction man occur.
Take appropriate measures so that water does not enter the hole and so that the hole is
not blocked.
Fig. 3-2. Blocking of the hole in the rear cap
yFor details about the installation dimensions, refer to the external dimensions given on
the specification sheet or delivery specification.
yInstallation Procedure
y2 inch pipe mounting model
Attach the junction box to a vertical or horizontal 2 inch (50 A) pipe using the mounting
bracket and U bolt. There are two bolt holes in the rear panel of the junction box. Attach the
bracket using these bolt holes. Secure the foundation of the pipe firmly so that it does not shake.
yWall-mounted model
Attach the junction box to a wall using the wall mounting bracket. There are two bolt
holes in the rear panel of the junction box. Mount the bracket using these bolt holes.
Bolts to attach the junction box to the wall are not supplied with the product. Please
obtain appropriate bolts beforehand.
