The BM 702 level gauge is designed solely for measuring the level, distance, volume and reflection of liquids, pastes, slurries, particulate materials and solids. The BM 702 level gauge does not form part of an overfill protection system as defined in the WHG (= German water pollution regulation). Local codes and regulations apply to its use in hazardous areas. Responsibility as to suitability and intended use of these level gauges rests solely with the user. Improper installation and operation of our level gauges may lead to loss of warranty. In addition, the "General conditions of sale", form the basis of the purchasing contract. If you need to return the level gauge to the manufacturer or supplier, please refer to the information given in Section 5 Handling and storage 1 Safety advice Depending on the version, the device will weigh between approx. 5 kg and 30 kg. To carry, use both hands to lift the device carefully by the converter housing. If necessary, use lifting gear. When handling the BM 702, avoid hard blows, jolts, impact, etc. When storing the "Wave-Stick" version, make sure that the device is not placed on its side on the PTFE antenna, as this may cause the rod to bend. 3 Installation and operating instructions BM 702 (07/00) 2 Installation Most of the BM 702 versions are supplied in fully assembled condition.

No current measured value: The device is searching for a new value. If the search for a plausible level fails for a certain time, "SIGNAL DOWN" appears as error display. Signal too strong: Mean of reflected microwaves is very high. Gain is automa-
tically stepped down. Poor spectrum: Brief showing of this marker has no significance. If permanently on, this may result in uncertain (incorrect) measured values or the error message
"NO M.VALUE". No measured value as yet: Evaluable measured values not available after the device has been started up. Measured value automatically set to the level of the tank bottom. This marker disappears when the first valid measured value is obtained. Tank bottom: In tanks with dished bottom, for example, the measuring signal can
"disappear" if measurements are carried out near the bottom. The measured value is then automatically set to the level of the tank bottom.

The bottom reference point is that point in the tank on which the microwaves of the BM 702 hit and from which they are reflected. This may be the tank bottom (symmetrical tank with flat bottom) or the non-horizontal part of the bottom (e.g. tank with dished bottom) or an additionally fitted plate. The BM 702 cannot measure below this point (sump in the tank). Note: When the tank is completely empty and the tank bottom provides good reflections
(flat, not dished bottom!), the tank height can also be automatically determined with the aid of Function Fct. 3.5.1 AUTO TANKH. Before confirming, check carefully that the proposed tank height is plausible!
Block distance The block distance function (Fct. 3.1.2) defines a zone below the top reference point in which measurements are not meant to take place. The value should be at least 10 - 20 cm greater than the length of antenna+antenna extension, or at least 20 cm in the case of the Wave-Stick. Signals within the block distance are suppressed; a rise in the tank filling above this limit
(response threshold) will lead to a measuring result corresponding to a distance = block distance, when Fct. 3.5.6 BD-DETECT. is switched on. Scaling of the current output The scaling of the current output (Fct. 3.3.3: level 1 = 4 mA ; Fct. 3.3.4: level 2 = 20 mA) should if possible lie within the measuring range (between bottom reference point and response threshold). By pressing the two upper keys (

Empty-tank spectrum To enable the BM 702 to identify and blank out interference signals, e.g. caused by fixed and moving tank internals, the tank profile (empty-tank spectrum) needs to be recorded once only prior to (initial) start-up. For recording, the tank should be completely empty and all moving parts (e.g. agitators) switched on. If major interference through internals is not expected, recording of the empty-tank spectrum can also be dispensed with, since the factory has already carried out and stored a partial empty spectrum of the flange system. Empty-tank spectrum recording via display After selecting menu item Fct. 3.5.2, press key empty spectrum is currently ON or OFF. Then press the use the key to choose between the following options:
. The display then shows whether the key if no change is to be made, or ON: the empty-tank spectrum is (again) switched on and taken into account for OFF: the empty-tank spectrum is not taken into account for measurements, but remains stored in the BM 702 and can be switched on again at a later date. RECORD: the existing empty-tank spectrum is to be deleted and a new one measurements. recorded. 15 Installation and operating instructions BM 702 (07/00) After selecting "RECORD": if other parameters had previously been changed, the query
"ACCEPT YES" is first made as to whether they are to be stored. In this case, confirm by pressing key to select one of the following options:
. To record, use the MAX. VALUES: (only maximum values are taken into account when the empty-tank spectrum is recorded; useful e.g. with difficult agitators). AVERAGE: (values are averaged; this setting can be used for most applications). key, press the key to select TOTAL or the key to select After selecting with the PARTIAL. When TOTAL is selected, the empty-tank spectrum is recorded over the entire range
(tank height). If the tank has not been fully drained, the empty-tank spectrum can also be recorded up to a certain distance, in which case the menu item PARTIAL should be selected. When this has been selected, a query takes place by way of the key concerning the distance value up to which the empty-tank spectrum is to be recorded. The tank area below the current filling level is then excluded from the empty-tank recording. It is recommended to maintain a safety distance of 20 to 30 cm from the actual product distance. Subsequently press key to start recording the empty-tank spectrum. The display starts with 200 and counts down to 0. The sign WAIT... is shown in the display. READY appears after approx. 1-3 minutes. Then press key five times to store the recorded empty-tank spectrum, which is taken into account for measurements. Empty-tank spectrum recording via PC-CAT Connect the BM 702 and press in the display mode of PC-CAT the key combination Ctrl-L. The type of empty-tank spectrum can be selected by one of the following keys:
1: Max.Values 2: Average 4: Max. Partial 5: Avg. Partial A: Break Tank bottom tracing mode (FTB) The BM 702 includes an additional function for measuring reliably low levels in tanks with flat bottom and poorly reflecting products (low dielectric constant). This tank bottom tracing system (abbreviated FTB) is activated in the vicinity of the tank bottom (max. 20% level). Given higher levels, the normal measuring method is used (reflection from the pro duct surface). If the measurement jumps to the correct level only after filling above a certain level (approx. 0.3-1.0 m), you can activate the FTB function Fct. 3.5.7 PARTIAL. The relative permittivity of the tank product must be set in Fct. 3.5.8. If it is not known, enter the figure of 2.0. Since the exact position of the tank bottom must be known for this process, it is advisable when using the FTB to determine the tank height automatically with an empty tank, using Fct. 3.5.1. r Conversion table/Volume table A table consisting of a maximum of 50 points can be stored in the BM 702 for non-linear or linear conversion of the level, e.g. into a volumetric value. This table, however, can only be programmed with the PC-CAT program (Fct. 3.7.2). 16 Installation and operating instructions BM 702 (07/00) e Sequence for setting parameters (example) (for version with local display) The following description refers to a storage tank with the parameter examples taken from the illustration in this Section.
