1. Introduction
The new linear „Absolute“ encoder and indicator unit AZ16 is based on the proven magnetic
measuring principle. According to its battery supply, no wirings are necessary and the systems
is able to operate as a complete stand alone unit. The max. possible measuring distance
amounts to 8 meters. By using the AUTO-POWER-OFF mode the max. service life span of the
battery amounts up to 3 years.
The external magnetic sensor is connected fix to the indicator by a drug chain suitable cable.
Further a version with an internal sensor and a guidance rail is available (AZ16I).
Characteristics of the AZ16E (external Sensor):
The system consists of
- an extensive programmable Display unit
- the external Magnet Sensor "AZS", which its cable length is available up to 20 meters
- an absolute coded Magnetic Tape with a max. measuring Length of 8 meters
The AZS sensor is contactlessly moved over the magnetic tape. It is resistant against abrasion,
dust, dirt and water (protection class IP 67).
The user must provide and guarantee for a suitable mechanical guiding system, to guide the
sensor and keep it along the whole movement in the correct distance (0... 1.5 mm) to the
magnetic tape. The sensor must be installed coplanar to the tape.
2. Safety
Please note: Before first commissioning read this installation manual carefully and
observe absolutely the installation instructions. The measuring system is only dedi-
cated for recording lengths. The type label is intended for exact identification of the
measuring system. The label is situated on the indicator housing. It informs about
the exact type designation (see chapter 9), the delivery date and the production
number. When contacting the company ELGO Electric GmbH please use these
terms.
Attention!
The company ELGO Electric GmbH is not liable for possible damages to machines
and or to persons, which can result from defective material at the measuring sys-
tem and the following circuit. The machine manufacturer is responsible for taking
and realizing the necessary safety precautions.

3. Determination of the rail and tape length
Basically the following applies with an order of magnetic tape:
Ordered length of tape = effective measuring distance + 100 mm
For further details see the „Type designation“ at the end of the manual.

5. The AZ16E in operation
5.1 Initial operation
5.1.1 Detection of measuring direction
The Magnet Sensor „AZS“ and the magnetic tape are provided with a marker, in order to signal
the installation direction. The markings of sensor and tape must point to the same direction.
The counting direction (+/-) is reversible in parameter P01 (see chapter 5.4).
5.1.2 Referencing
Setting the zero-point: A new AZ16E unit shows always the absolute value of the magnetic
tape and should be calibrated to the zero point for one time. The reference value default setting in
register P09 is 0. To assign a zero point to an arbitrary position, move to the desired
zero-point and press the buttons F + Set together.
Reference value: Alternatively an arbitrary value can be entered in P09, to set a demanded ref-
erence measurement by pressing F + Set together.

Press Incr/Abs to switch over from „absolute“ to „relative“ measurement:
The actual value shows „0“ and also "INC" appears in the display.
With a renewed pressing of Incr/Abs the display switches back to
„absolute“ measurement and the display shows the real absolute value
again and „ABS“ also.

6. Battery change
To change the battery with a standard unit (integrated battery version) remove battery cover
on the rear, by pressing the outer edges gently (like shown on the photo). Useful are commer-
cial battery types, size C, 1.5 V) with good quality. All values and settings remains in case of
changing the batteries.
Please pay attention to the correct polarity!
The polarity is marked inside the housing.

7. Magnetic Tape
The magnetic tape consists of 3 components (see picture 1)
• a magnetized flexible rubber tape (Pos. 3), which is connected factory made with a
• steel band (Pos. 5) and a
• covering band (Pos. 1) , which is intended for the protection of the rubber tape.
• For mechanical protection of the magnetic tape the covering band must be stuck on. Addi-
tionally it protects the magnetic tape from extreme external magnetic influences.
To reach a complete adhesion between the several materials a special sticky tape is used
(Pos. 2, Pos. 4, Pos. 6).

with the magnetic rubber tape to the inside (min. bend radius 150 mm).

7.2 Processing note for sticking
The provided sticky tapes stick well on clean, dry and plain surfaces. The more pollution exists
the more proper the surface has to be. A surface roughness of Ra<= 3,2 (Rz<= 25 / N8) is rec-
ommendable. Typical solvent for cleaning surfaces are a 50/50 - isopropyl-alcohol / water mix-
ture or heptane. The surfaces of materials as copper, brass etc. should be sealed to avoid an
oxidation. The stability of the adhesion is directly depending on the contact, which the adhesive
develops to the stuck surfaces. A high pressure results in a good surface contact.
The optimal sticking temperature is between + 21°C and 38°C.
Avoid colder sticking surfaces than + 10 °C, because in this case the adhesive becomes to hard
and perhaps a sufficient immediate adhesion is hardly to achieve. After proper sticking the sta-
bility of the connection is ensured also when the temperature is below zero. The final tackiness
of a sticking is from experience reached after approximately 72 hours (at + 21 °C). For sticking
use only the provided sticky tape.
7.3 Resistance to chemicals of the magnetic tape
The magnetic tape shows no or only small effects when contacting permanently the following
materials after 2 to 5 years: Formic acid, Glycerol 93°C, Linseed oil, Soy beans oil, Cotton seed
oil, N-hexane, Lactic acid, Formaldehyde 40%, Isooctane, Petroleum.
Poor to medium effects result when contacting permanently the following materials after ap-
proximately 1 year: Acetone, Gasoline, Acetic acid 30%, Olein acid, Acetylene, Steam, Acetic
acid, pure Acetic acid, Sea water, Ammonia, Acetic acid 20%, Isopropyl ether, Stearic acid 70°C
anhydrous, Kerosene.
Strong effects result when contacting permanently the following materials after 1 to 5
months: Benzene, Nitric acid 70%, Turpentine, Toluene, Lacquer solvent, Nitric acid red and
Vitriolic, Carbon Tetrachloride, Trichloroethane, Nitrobenzene, Hydrochloric acid 37% and 93°C,
Tetrahydrofuran, Xylene.
7.4 Sticking and cutting
Attention! When sticking the magnetic tape pay attention to the marks on the mag-
netic tape. A faulty installation delivers incorrect values. An already stuck magnetic
tape is ruined after removing and can't be used again. Observe also the counting
direction of the measuring system.
The magnetic tape and the covering band must be cut to the exact length before sticking:
Magnetic tape length = measuring length + 0.1 m
Preferably the magnetic tape should be stuck into a nut or aligned to an edge.
Procedure for sticking:
1. The magnetic tape is already factory bonded with the steel band, in between is a double sided
sticky tape. Stick the provided sticky tape onto the carrier side (= steel band).
2. Now adjust the magnetic tape and stick it onto the surface. The best way to stick the mag-
netic tape is to do it in two steps. Remove the first half of the adhesive film from the sticky tape
and stick it, then do the rest length.
3. Then stick the sticky tape onto the covering band. It is not important on which side of the
covering band the sticky tape is stuck on.
4. Stick the covering band onto the visible brown magnetic rubber tape
