1. APPLICATION
The EasyTREK is a liquid level transmitter, measuring by the non-contacting ultrasonic principle.
The transmitter comes with scaleable 4 ... 20 mA output, programmable relay and HART communication.
This intelligent microprocessor based smart level transmitter is suited to measure most liquids under various
process conditions.
The device can be programmed using the supplied magnet or via HART if equipped.

- Page 2 3. INSTALLATION ATTENTION! Before mounting the unit in its final position, make sure that the programming points of the unit are accessible with the supplied magnet, the LEDs are clearly visible and the level of the liquid can be changed between its minimum and maximum during the programming session. If any of the above conditions are not met, the programming should be carried out before mounting the unit in its final position.
- Page 3 Touch-Magnet Programming is only possible if the EasyTREK receives valid echo i.e. “ECHO” LED is lit! Is the “ECHO” LED blinking the search for echo is in process. Green LED Red LED In case of EasyTREK with HART communication (SCA - 3 Touch-Magnet Programming - 4) is only possible if the transmitter is in the “LEV"...
