1 Safety instructions
1.1 Designated use
Digital transmitter TMD1 transfers the signal relate to liquid level and liquid temperature in a tank, or
the status of power outage and malfunction via an external device and also transfers all tank data to a
receiver including that of the peripheral equipment by digital transmission system. TMD1 is used in
combination with float level gauge LT5.
1.2 Installation, commissioning, and operation
•Mounting, electrical installation, start-up, and maintenance of the instrument may only be per-
formed by trained personnel authorized by the operator of the facility.
•Personnel must read and understand these installation instructions before performing the proce-
dures.
•The instrument may only be operated by personnel who are authorized and trained by the operator
of the facility. All instructions in this manual must be observed.
•The installer must make sure that the measuring system is correctly wired according to the wiring
diagrams. The measuring system must be grounded.
•Observe all law and regulations applicable and valid for your country and pertaining to the opening
and repairing of electrical devices.
1.3 Product requirements
Power source
Check the voltage of the power supply before connecting it to the product. It should be the exact voltage
required for proper operation of the product.
Connection to other devices
It is possible to connect to other devices explained in this instruction. Refer to each operation instruc-
tion when connecting to devices.
Ground
Do not remove earth terminal or earth wire when the power is on.
Power cable
Use a power cable specified by our company. The product should be protectively grounded before it is
connected to a measurement object or an external control circuit.

1.4 Operational safety
Hazardous area
•Use the explosion proof type for measurement in areas where explosion hazards are present.
•Devices installed in areas having explosion hazards must not be opened when the power is on.
•Strict compliance with installation instructions and - ratings, as directed in this supplementary doc-
umentation, is mandatory.
•Device maintenance and repair is restricted to meet explosion proof regulations.
•Tighten the cable gland firmly.
•Devices employed in areas having explosion hazards should be installed and wired in keeping with
explosion proof regulations.
•Ensure that all personnel are properly qualified.
•Observe the certification requirements as well as national and local regulations.
Changes or modifications other than those expressly approved by Endress+Hauser
are strictly prohibited. Unauthorized modifications can cause malfunction or dam-
age, resulting in serious injury or death.

3.1 Incoming acceptance, transport, storage
3.1.1 Incoming acceptance
Check the packing and contents for any signs of damage.
Check the shipment, and make sure that nothing is missing and that the items match your order.
3.1.2 Transport
•Follow the safety instructions and conditions of transportation for instruments in excess of 18kg
(40 lbs.).
•Do not lift the measuring instrument by its housing during transportation.
3.1.3 Storage
Pack the measuring instrument so that it is protected against impacts during storage and transporta-
tion.
The original packing material provides the optimum protection for this.
The allowed storage temperature is -20°C to +60°C (-4°F to +140°F)
3.2 Installation conditions
Digital Transmitter TMD1 is designed to be installed on the rear of a level gauge and placed at outside
the tank as shown below. The unit (level gauge and transmitter) is primarily employed in measurement
level; particularly for crude or other oil in refineries and storage tanks. Other applications may include
acid, alkaline fluid and fat products in chemical industry storage tanks.

3.5 Installing TMD1 on float gauge (LT5)
Digital transmitter TMD1 is designed to be installed on the rear of the float gauge head by using a
flange.
Installation procedure
Stud bolt, nut, washer, and coupling are supplied with TMD1 in a plastic bag.
1. Insert the stud bolt in the rear cover of the float gauge.
2. Make sure that the coupling on TMD is secure when installing on low pressure float gauges.
• Make sure that coupling on both TMD and float gauge is secure when installing on medium or
high pressure float gauges.
This completes installation procedure.

Installation procedure
1. Remove the TMD rear cover.
2. Install TMD in float gauge while engaging coupling groove with coupling pin.
This completes installation procedure.
•If the coupling groove and the pin positions are not aligned, the installation surface between LT and
TMD will rise and not match with the position. Do not install the coupling using excessive force.
Check coupling position and reinstall TMD, if needed.
•When the professional installation and adjustment service of Endress+Hauser are required, all pro-
cedures, including unpacking, are conducted by our service technician.

4 Cable connection
For TMD cable connections, the terminal configuration and internal wiring vary depending
on specifications. Be sure to confirm delivery specifications to prevent incorrect wiring.
Select cables so that TMD terminal power supply can reach to a nominal voltage of 90% or
more in the following cases.
4.1 Calculation of wiring transmission distance
Calculation sample
1. Calculation object is to find resistance between circuits and electrical capacity limits.
• One-way resistance: Max. 120 Ω
• Maximum capacity between circuits: 30 μF
2. Maximum capacity of cable resistance and between circuits (see the following table).
