Safety Precautions
Be sure to read and observe the following requirements!
The APT2000TC-0(H)-00 Transmitter is approved for operation in safe areas and hazardous
locations DIV 2 (USA/Canada only).
Before connecting the Transmitter to a power supply unit, make sure that this is not capable
of outputting more than 40 Vdc (safe areas) / 30 Vdc (DIV 2).
The APT 2000PH-0(H)-IS Transmitter is approved for operation in hazardous locations
DIV 1 (USA/Canada) / Zone 1 (Europe).
Before connecting the Transmitter to a power supply unit, make sure that this is an associ-
ated apparatus.
The measuring inputs of the APT 2000PH-0(H)-IS Transmitter may be led into Zone 0
(Europe).
However, be sure to observe the national regulations concerning Zone 0 applications.
The Transmitter itself is not approved for operation in Zone 0!
Whenever it is likely that the protection has been impaired, the Transmitter shall be made inoperative and
secured against unintended operation.
The protection is likely to be impaired if, for example:
❏the Transmitter shows visible damage
❏the Transmitter fails to perform the intended measurements
❏after prolonged storage at temperatures above 70 °C
❏after severe transport stresses
Before recommissioning the Transmitter, a professional routine test must be performed. This test should be
carried out at our factory.
The Transmitter shall not be used in a manner not specified by this manual.

Proper Use
The APT2000TC Transmitter is used for conductivity
and temperature measurement in chemical, pulp and
paper, biotechnology, food processing, pharmaceuti-
cal, electroplating, and water/wastewater industries.
It can either be mounted on site or in a control panel.
The APT2000TC-0(H)-00
Transmitter is approved for opera-
tion in safe areas and hazardous
locations DIV 2 (USA/Canada only).
Before connecting the Transmitter
to a power supply unit, make sure
that this is not capable of outputting
more than 40 Vdc (safe areas) /
30 Vdc (DIV 2).
The APT2000TC-0(H)-IS Transmit-
ter is approved for operation in haz-
ardous locations DIV 1 (USA/Can-
ada) / Zone 1 (Europe).
Before connecting the Transmitter
to a power supply unit, make sure
that this is an associated appara-
tus.
The measuring inputs of the APT
2000PH-0(H)-IS Transmitter may
be led into Zone 0 (Europe).
However, be sure to observe the
national regulations concerning
Zone 0 applications.
The Transmitter itself is not ap-
proved for operation in Zone 0!

Installation and Commissioning
Installation and commissioning of
the Transmitter may only be carried
out in accordance with this instruc-
tion manual and per applicable local
and national codes. Be sure to ob-
serve the technical specifications
and input ratings.
Before connecting the
APT2000TC-0(H)-00 Transmitter to
a power supply unit, make sure that
this is not capable of outputting
more than 40 Vdc (safe areas) /
30 Vdc (DIV 2).
Before connecting the
APT2000TC-0(H)-IS Transmitter
to a power supply unit, make sure
that this is an associated apparatus
(for input ratings refer to the Control
Drawing or the annex of the EC
Type Examination Certificate).
Do not use alternating current or
mains power supply!
When commissioning, a complete
configuration must be carried out.
For easier installation, the terminal strips are of a
plug-in design. The terminals are suitable for single
wires and flexible leads up to 2.5 mm2(AWG 14)
(see Pg. 9).
A connection example is shown on Pg. 14.

The Honeywell 5000TC toroidal
conductivity sensor may only be
used in combination with the
APT2000TC-0(H)-00 Transmitter.
For special mounting conditions of
the sensor, the cell factor can vary
between 4.0 and 4.5. Therefore the
user should perform a wet calibra-
tion of each new sensor to deter-
mine the exact cell factor.

Safety Functions
Sensoface sensor monitoring
Sensofaceprovides information
on the sensor condition. A sad
“Smiley” indicates that there is a
Sensocheckmessage.
Sensocheck signals a short cir-
cuit of the primary coil and its lines
as well as an interruption at the
secondary coil and its lines. Senso-
check can be switched off. With
Sensocheck switched off, no
friendly Smiley appears.
For more detailed information, see chapter “Diagnos-
tic, Maintenance and Cleaning” (Pg. 26).
GainCheckmanual instrument self-test
Simultaneously pressing Yand "
starts the manual instrument self-
test.
A display test is carried out, the software version is
displayed and the memory and measured value
transmission are checked.
Automatic instrument self-test
The automatic unit self-test checks the memory and
the measured-value transmission. It runs automati-
cally in the background at fixed intervals.

Operation
18
Outputs
Current loop (4 to 20 mA)
The current loop transports power to and output sig-
nals from the Transmitter. The current is controlled
by the process variable selected in the configuration.
The current characteristic can be configured as lin-
ear or logarithmic curve for conductivity and resistiv-
ity.
The current beginning and end can be set to repre-
sent any desired value.
If LIN (linear characteristic) is chosen, the minimum
span is 5% of the selected process variable / mea-
surement range. If LOG (logarithmic characteristic) is
chosen, the minimum span is one decade within the
chosen range.
To check connected peripherals (e.g. limit switches,
controllers), the loop current can be manually speci-
fied (see Pg. 28).
HART communication
The APT2000TC-H-.. Transmitter can be remote
controlled via HARTcommunication. It can be con-
figured using a handheld terminal or from the control
room. Measured values, messages and instrument
identification can be downloaded at any time. This
allows easy integration also in fully automatic pro-
cess sequences.
For more detailed information, refer to the HART
Command Specification.
Alarm
During an error message the alarm LED flashes.
Alarm response time is permanently set to 10 sec.
Error messages can also be signaled with a 22 mA
signal via the loop current (see Configuration,
Pg. 20).

Configuration
The instrument arrives from the factory configured
and ready to operate as a conductivity transmitter.
This section provides detailed procedures for chang-
ing operation values for specific applications.
Activate with CONF
change parameter with Yand ",
confirm/continue with ENTER,
end with CONF.
Mode code “1200”
During configuration the Transmitter
is in the Hold state, the loop current
is frozen.
When the configuration mode is exited, the Transmit-
ter remains in the Hold state for safety reasons. This
prevents undesirable reactions of the connected pe-
ripherals (e.g. limit switches, controllers) due to in-
correct settings. The measured value and Hold are
displayed alternately. Now you can check whether
the measured value is plausible and specifically end
the Hold state with ENTER. After a relax time of
20 sec (for measured value stabilization) the Trans-
mitter returns to measuring mode.
The configuration parameters are
checked during the input. In the
case of an incorrect input “ERR” is
displayed for 3 sec. The parame-
ters cannot be stored with ENTER
until the input has been repeated.
