0,03 to 0,045 in. (0,762 to 1,143 mm) stainless rod as filler material in the beveled area.
Adjust amperage for penetration pliers (1/8").
6.
Remove mandrel after the welding operation.

MOUNTING POSITION
When the transmitter is mounted horizontally, the cable gland must be pointed downwards.
3.3
CALIBRATION
All transmitters are fully calibrated at the factory, to the conditions stipulated in users order. When the
customer has not requested calibration, the transmitter will be calibrated 0-100 °C.

WIRING
Under the cover (3) you will find the terminal board. Under the other cover (1) are the buttons for the
zero and span adjustment.
TERMINAL CONNECTION
Care must be taken to assure that the polarity of the power supply is correct, a reversal of wiring
polarity will not damage the transmitter, but it will not function until the wiring is connected correctly.

DIGITAL LOCAL INDICATOR
All temperature transmitters from the series TT-2000 are standard equipped with a digital display. In the
standard version closed covers are used. The push buttons and the display are behind the cover (3).
As an option an transparent cover can be delivered for the application as a local display in the process
(Option: "I" extra price). The full-scale point may be set to any value between 0000 and 9999 (4 digit)
H/EN/2000-TT/09-2021/09
External loads must be placed in the negative leg of
the 2-wire loop.
The figure left shows the wiring connection of the
transmitter. The 2-wires must be connected to 3 (-) and
4 (+) of the terminal board.
The signal wiring must be shielded and twisted pairs
yield best results. Do NOT run signal wiring in open
trays with power wiring, or near heavy electrical
equipment (Frequency controller or heavy pumps).
Shielding must always be connected at the side of the
power supply.
In case the mounting position is already connected to
earth (by tank or pipe line) do NOT connect the
instrument to earth. Please ensure that the instrument
is not connected to earth twice to prevent the
occurrence of an 'earth loop'. In applications with
synthetic mounting positions the case grounding
terminal (internal or external) must be connected to
earth.
