Complete documentation available on www.eltra.it
This device must be supplied by a Class 2
Power source or Limited Voltage / Current Circuit
Input Voltage: + 30V DC max
Input Current: 0.5A max
Teach-in procedure with SET button
• press SET button (at least 3 sec) -> the encoder enters into teach in procedure
(led B (GREEN) / led A (RED) on)
• keep pressed SET button (at least 3 more sec, 6 sec total) -> teach in procedure confi rmed
(led B (GREEN) / led A (RED) fl ashing 2 Hz frequency), 1 min timeout
• rotate the encoder shaft to initial position
• press SET button -> initial position set
(led B (GREEN) on / led A (RED) fl ashing), 10 min timeout
• rotate the encoder shaft to end position
• press SET button -> end position set
(led B (GREEN) / led A (RED) fl ashing 4 times (1,5 Hz frequency))
• led B (GREEN) on -> user parameters set
To reset to factory default (1 turn EAL - 15 turns EAML) press SET button at least 10 seconds
(led B (GREEN) / led A (RED) alternate fl ashing) -> led A (RED) on
Teach-in procedure with BEGIN/END inputs
• rotate the encoder shaft to start position
• set BEGIN input on high level (pulse) -> led B (GREEN) on / led A (RED) fl ashing (10 min timeout)
• rotate the encoder shaft to end position
• set END input on high level (pulse) -> end position set
(led B (GREEN) and led A (RED) fl ashing 4 times (frequency 1,5 Hz))
• led B (GREEN) on -> user parameter set
To reset to factory default (1 turn EAL - 15 turns EAML) set BEGIN / END inputs on high level simultaneously
(led B (GREEN) / led A (RED) alternate fl ashing) -> led A (RED) on

SAFETY ADVICES
• The transducer must be used in observance of its specifi cations. The transducer is a precision measuring
instrument and it is not a safety device.
• The personnel charges in mounting and commissioning of the device must be qualifi ed and carefully
follow installation instructions. It is strongly recommended to avoid any mechanical or electrical
modifi cation for safety reasons. The warranty will lose in case of any modifi cations.
• Don’t expose the device to stresses or impacts in order to ensure the correct functioning.
• Make sure that the mechanical coupling of the transducer shaft is designed with the appropriate elastic
couplings, especially in the case of excessive axial or radial movements.
• The mechanical coupling between motor and trasducer shaft has to be made with appropriate elastic
couplings, especially in the case of excessive axial or radial movements.
• Check the operating environment is free from corrosive agents (acids, etc.) or substances that are not
compatible with the device and with its IP rating.
• Check the connection of the device to the ground; if necessary, provide an additional external connection.
• Products with variant code (a number or combination of numbers after “.”) may have different mechanical,
electrical or connections from standard product. Please refer to the additional documentation.
• Installation and wiring must be performed by trained personnel in a POWER-OFF condition.
• To prevent short-circuits, insulate unused wires at different lengths; do not use unused pins on the
connector.
• Before switching on, verify the voltage range applicable to the device.
• Place power and signal cables in order to avoid capacitive or inductive interferences that may cause
malfunction of the device. Place also transducer cable far from power lines or any other cable with high
noise levels.
• The user who integrates the transducer in his appliance must observe CE regulations and he is responsible
for the CE marking of the end machine/device.
• The malfunctions due to failure to observe these usage and installation precautions will loose the
warranty.
• Eltra considers itself free from any liability for damages or injuries due to non-observance of these
directives.
