1. UNPACKING AND INSPECTION ● Carefully unpack and inspect the equipment; in case of damage, file proper reserves with carrier.

● The identification of the instrument is indicated on the connection head.

2. STORAGE The material should be stored in covered area, in the original packing and protected.

The storage temperature : - 40 to +80°C

3. OPERATING PRINCIPE The level detector LIDEC is detecting the free liquid presence as high or low level alarm with a current output (18/6 mA) in power supply loop or a dry contact output. The installation of the probe can be either horizontal or vertical.

The operating principle is based on the absorption of mechanical waves from the sensitive part of the metallic probe in case of contact with liquid. A piezo-electrical ceramic generates these waves then detects their amplitude after reflection on the probe extremity. The detected absorption causes either a variation of the consumption current, from 18 to 6 mA or reverse, or the switching of the relay.

This equipment offers a reliable fully fail safe operating system. The alarm occurs in following conditions:

● Liquid detection

● Electronic and/or sensor failure

● Power supply failure

In addition, in the dual box type variation are placed one test switch per channel, allowing, by using a test magnet, to check the efficiency of the alarm sequence in remote conditions, without access to the probe and without opening the enclosure. When activated, the test switch simulates the detection of liquid, and starts the alarm sequence.

4. OVERALL VIEW AND DIMENSIONS Refer to drawings : M32017 Lidec 20-70 DR, Polyester box, Relay output

M31999 Lidec 20-70 D, Polyester box, Current output

M36114 Lidec 20-70 DR, Stainless steel box, Relay output

M34227 Lidec 20-70 D, Stainless steel box, Current output

M34229 Lidec 20-70 D, dual stainless steel box with test, Current output

NOTE: Due to that principle, the probe must not be paint, it must be cleaned periodically when used with viscous liquid.

8.2. Connection diagram of probe with test switch (dual box)

NOTE: Make sure to respect the correspondence between probe and electronic board: "L" (low alarm) probe to be connected on "L" board; "H" (high alarm) probe to be connected on "H" board.

CAUTION: The connections are to be made with power switched off.

● Composition : 2-wires cable for current loop connection (polyester or stainless steel box); 4 wires cable with relay output connection (polyester or stainless steel box), 4-wires cable with current loop connection (dual stainless steel box with test),

● Diameter of the cable : see § 5 Technical data

8.5. Special precautions for the intrinsically safe installation Ex ia

NOTE: - Make sure to respect the intrinsic safety requirements (see chapter 8.5)

- The screen must be connected to ground on the voltage supply side, and not on the Lidec enclosure.

Ex ia IIIC T80°C or T95°C or T130°C Da IP6X under certificate n° LCIE 02 ATEX 6181X and IECEx LCI 11.0001 X, meaning that it must be

associated to an intrinsically safe certified device, complying with the transmitter's intrinsic safety parameters.

● Ratings on dry contact line (terminal B3) : U max £ 28 Vdc; L int. = C int. = 0

The result of such association is an intrinsically safe system, which must be certified. The certification is the responsibility of the provider of the associated device.

As consequence, a suitable Zener barrier must be installed in Safe Area, to be inserted in line between LIDEC and power supply / acquisition device on B1, and in line between LIDEC and alarm unit on B3 when used.

9. LEVEL ALARM ADJUSTMENT (only for vertical installation) The potentiometers with red varnish are factory pre-set, and not to be modified.

The LIDEC are factory pre-set 5 mm above the low point of the probe for water level detection.

The "SENS" potentiometer situated on the circuit board allows adjustment of the sensitivity related to the liquid wave absorption properties, and as consequence to adjust lightly the alarm level.

10. TEST ● Check the electric connection according to the diagram § 8.6.

● Operating cycle test: check the contact relay releasing or the current loop variation by tightening the probe between fingers to simulate the liquid absorption.

● For the LIDEC with dual box and test switches, the alarm sequence is checked by approaching a magnet on top of the housing, successively in the area proper to each channel: the relevant alarm should be activated immediately.
