2.7 CALIBRATING TR420E/E6 TRANSMITTERS
2.7.1 Calibration
The TR420E/E6 Continuous Output Transmitter for Hazardous Locations requires minimal to no initial
calibration depending on the media. The device is shipped from the manufacturer with its 4 mA (0%)
point set on empty indication and its 20 mA (100%) point set on full indication. The 4 mA and/or 20 mA
points can be readjusted by the end user if necessary.
2.7.2 Adjustment Procedure
This procedure should be used when the process level can be moved from empty to full, or from the
actual 4 to 20 mA points. A digital multimeter is recommended, but not required for calibration.
1 Connect the digital multimeter (set to read
20.0 mA full scale) to the control board on the
transmitter. Attach the “common” or black
lead from the meter to the rtn terminal on the
control board. Then, attach the “mA” or red
lead from the meter to the out terminal on the
control board.
2 Connect the transmitter to a 24 VDC power
supply.
3 A green LED will illuminate on the PCB to
indicate that the board is powered up.
4 Lower the oat on the probe all the way to
the bottom, indicating an empty tank. The
multimeter should read 4.0 mA. If necessary,
adjust the low trim pot with a small at
blade screwdriver. By turning the screwdriver
clockwise, the output will rise. By turning the
screwdriver counter-clockwise, the output will
lower. Turn accordingly to achieve an output
of 4.0 mA.
5 Raise the oat on the probe to the top of the indication length, signaling a full tank. The multimeter
should read 20.0 mA. If necessary, adjust the high trim pot with a small at blade screwdriver. By
turning the screwdriver clockwise, the output will rise. By turning the screwdriver counter-clockwise,
the output will lower. Turn accordingly to achieve an output of 20.0 mA.
6 Cycle the oat from the bottom to the top of the indication length, verifying the outputs at both
positions. Repeat steps 4 & 5, if necessary to obtain the best accuracy.
2.7.3 Fault Mode
A “fault” condition will show by illuminating the red LED on the control board. If this occurs, the output
signal has been wired incorrectly, or not wired at all.

3.0 REFERENCE INFORMATION
This section illustrates an overview of the TR420E/E6 Continuous Output Transmitter operation, as well as
information on troubleshooting common problems, agency approval listings, replacement parts, and detailed
physical, functional and performance specications.
3.1 DESCRIPTION
The vertically-mounted TR420E/E6 Continuous Output Level Transmitter for Hazardous Locations
is equipped with an integral signal conditioner and provides a reliable 4-20 mA, 0-5 VDC or 1-5 VDC
proportional electronic output in tank levels up to 15 feet. It can be used to input programmable controllers,
meters and other digital receivers for accurate and continuous measurement in many liquid level applications.
The TR420E/E6 is FM-approved with an explosion-proof rating for Class II, Div. I, Groups E, F & G
hazardous (classied) locations, indoor/outdoor (Type 4, 4X). Float materials are available in stainless steel
with a variety of mounting types. Additional options include high and low level alarms as well as SPST or
SPDT switch contacts.
3.2 THEORY OF OPERATION
3.2.1 Basic Operating Principle
The TR420E/E6 Continuous Output Transmitter for Hazardous Locations contains a series of magnetic
reed switches within its vertical sensor stem. As the oat travels along the transmitter’s stem in correlation
to the uid level inside the tank, its internal magnets actuate the series of reed switches. Then, a signal is
electronically conditioned through the built-in transmitter board to provide a current output.
3.2.2 TR420E/E6 Probe
Each probe segment contains 64 discrete resistors, forming a resistive daisy chain
or series circuit. The segments have been congured as a voltage divider where the
magnetic reed switches serve as the tapping point to the circuit. As each switch closes,
the voltage divider varies in proportion to the switch position. Ultimately, the probe
connectors allow the voltage divider to extend the length of the probe.
3.2.3 TR420E/E6 Control Board
The control is a current transmitter that accepts high-level signal inputs from the
resistive probe and drives a standard 4-20 mA current loop to enable valves, actuators
and other devices commonly used in the process. During the transmission, the input
signal is buffered by an input amplier that is used to scale the input signal. The signal
is then divided by voltage and fed back to the input signal. There is limited interaction
between setpoints, which allows the user to set each trimpot once and avoid several
attempts to lock-in the values.
A red LED light illuminates to notify the user of an open 4-20 mA loop or noncompliance
of the output stage. In the event the wire from the HDR1 Pin 3 is opened, the LED will
light up. If a large input overdrive forces the signal too close to the input power supply
voltage, the LED will also signify a problem.
Alternatively, a green LED light is present on the control board to indicate power to the board. If the
green LED is illuminated, the control board is powered up and ready for use.
