All operations described in this instruction manual have to be carried out only by trained personnel or an accredited person. Warranty and post warranty service must be exclusively carried out by the manufacturer.
Improper use, installation or set-up of the level meter can result in crashes in the application (overfilling of the tank or damage of system components).
The manufacturer is not responsible for improper use, losses of work caused by either direct or indirect damage, and for expenses incurred during installation or use of the level meter.

If you can not eliminate all interference, which could affect the measurement of level, it is recommended to use the procedure "TEACHING" (see chap. 10.2 Service settings). This procedure sets the level meter to mode, which suppresses false reflections.

Electrical connection must be done in de-energized state!
With regard to possible occurrence of electrostatic charge on non-conductive parts of the level meter for explosive areas (GRLM–70Xi(XiT)), level meters must be grounded with ground terminal! It will be done using a screw placed on the head of the level meter under the cable bushing.

The voltage source should be preferably realized as a stabilized power supply unit with safe voltage from 18 to 36 V DC, which can be a part of the evaluation or display device.
In case of strong electromagnetic interferences (EMI), parallel cable ducting with power lines, or when cable length exceeds 30 m we recommended to use shielded cable.

You can choose type of electrode from three options: ROD – ROPE – ANCHORING ROPE
You can enter the length of electrode by two ways: MANUAL – AUTO DETECTION.

When the setting of the type and length of the electrodes is carried out outside the tank it is required to insert a metallic plate (with diameter greater than 200 mm) in the place of process connection (thread) before this setting - see Fig. 7. The metal plate must be in good electrical contact with the thread.
The procedure for replacing or shortening the electrode is given in chapter 12 on page 22.

1) Error is larger at the beginning and end of the rod or rope electrode. More detailed informations can be found in Fig. 30 and 31.2) Dead zone = Blind zone = Blocking distance3) The length of dead zone at the beginnig / at the end of the electrode. (The length of dead zone is 110 mm at the end of rope electrode.)4) Level meter displays last measured value.5) Including 250R resistor in case of HART connection.6) hatched space applies for set measurement sensitivities: low (1), moderate (3) or user (1-4). When the sensitivity set to high (5), or custom (5-8), the dead zone at the beginning and at the end of the electrode extends, see "Table of sensitivity of the measurement" on page 28.
