1. Safety Instructions and Responsibility
1.1 General Safety Instructions
This operation manual is a significant component of the unit and includes important rules and
hints about the installation, function and usage. Non-observance can result in damage and/or
impairment of the functions to the unit or the machine or even in injury to persons using the
equipment!
Please read the following instructions carefully before operating the device and observe all
safety and warning instructions! Keep the manual for later use.
A pertinent qualification of the respective staff is a fundamental requirement in order to use
these manual. The unit must be installed, connected and put into operation by a qualified
electrician.
Liability exclusion: The manufacturer is not liable for personal injury and/or damage to property
and for consequential damage, due to incorrect handling, installation and operation. Further
claims, due to errors in the operation manual as well as misinterpretations are excluded from
liability.
In addition the manufacturer reserve the right to modify the hardware, software or operation
manual at any time and without prior notice. Therefore, there might be minor differences
between the unit and the descriptions in operation manual.
The raiser respectively positioner is exclusively responsible for the safety of the system and
equipment where the unit will be integrated.
During installation or maintenance all general and also all country- and application-specific
safety rules and standards must be observed.
If the device is used in processes, where a failure or faulty operation could damage the system
or injure persons, appropriate precautions to avoid such consequences must be taken.
1.2 Use according to the intended purpose
The unit is intended exclusively for use in industrial machines, constructions and systems. Non-
conforming usage does not correspond to the provisions and lies within the sole responsibility
of the user. The manufacturer is not liable for damages which has arisen through unsuitable
and improper use.
Please note that device may only be installed in proper form and used in a technically perfect
condition (in accordance to the Technical Specifications, see chapter 7). The device is not
suitable for operation in explosion-proof areas or areas which are excluded by the EN 61010-1
standard.

Gv150_02c_oi_e.doc / Nov-15 Page 4 / 9
1.3 Installation
The device is only allowed to be installed and operated within the permissible temperature
range. Please ensure an adequate ventilation and avoid all direct contact between the device
and hot or aggressive gases and liquids.
Before installation or maintenance, the unit must be disconnected from all voltage-sources.
Further it must be ensured that no danger can arise by touching the disconnected voltage-
sources.
Devices which are supplied by AC-voltages, must be connected exclusively by switches,
respectively circuit-breakers with the low voltage network. The switch or circuit-breaker must
be placed as near as possible to the device and further indicated as separator.
Incoming as well as outgoing wires and wires for extra low voltages (ELV) must be separated
from dangerous electrical cables (SELV circuits) by using a double resp. increased isolation.
All selected wires and isolations must be conform to the provided voltage- and temperature-
ranges. Further all country- and application-specific standards, which are relevant for structure,
form and quality of the wires, must be ensured. Indications about the permissible wire cross-
sections for wiring are described in the Technical Specifications (see chapter 7).
Before first start-up it must be ensured that all connections and wires are firmly seated and
secured in the screw terminals. All (inclusively unused) terminals must be fastened by turning
the relevant screws clockwise up to the stop.
Overvoltages at the connections must be limited to values in accordance to the overvoltage
category II.
For placement, wiring, environmental conditions as well as shielding and earthing/grounding of
the supply lines the general standards of industrial automation industry and the specific
shielding instructions of the manufacturer are valid. Please find all respective hints and rules on
www.motrona.com/download.html --> “[General EMC Rules for Wiring, Screening and
Earthing]”.
1.4 Cleaning, Maintenance and Service Notes
To clean the front of the unit please use only a slightly damp (not wet!), soft cloth. For the rear
no cleaning is necessary. For an unscheduled, individual cleaning of the rear the maintenance
staff or assembler is self-responsible.
During normal operation no maintenance is necessary. In case of unexpected problems, failures
or malfunctions the device must be shipped for back to the manufacturer for checking,
adjustment and reparation (if necessary). Unauthorized opening and repairing can have
negative effects or failures to the protection-measures of the unit.

Gv150_02c_oi_e.doc / Nov-15 Page 5 / 9
2. Application and Construction
The unit is used to increase the drive capability of existing encoder signals and to distribute the
signals to several channels. At the same time it provides potential separation between source
and target lines as well as level conversion.
In general, an incremental encoder output is limited to drive currents of 20 mA only on it's
impulse lines. The GV150 amplifiers increase the Fan-Out to 6 channels, each loadable with 20
respectively. 30 mA per line. The units can be used for encoder pulse transmission and for data
transmission applications as well.
Standardly GV150 and GV151 provide TTL (RS422) inputs (A, /A, B, /B, Z, /Z)
With option HTLIN1, the input is set to HTL level (12 … 30 V), and only the signals
A, B and Z are necessary (no inverted signals).
With option HTLIN2, the input is also set to HTL level (12 … 30 V), but all signals
must be applied (A, /A, B, /B, Z, /Z).
Each of the 6 output channels generates the signals (A, /A, B, /B, Z, /Z).
- GV150 provides always TTL/ RS422 standard and
- GV151 has individually programmable output levels TTL or HTL

3. Connections and Switch Settings
a. The unit is supplied by a power connector on the front side.
The power supply range is 18 …30 VDC.
b. For operation without potential separation, positions 3 and 4 of the internal DIL switch
S1 can be set to "ON". This will connect the input GND to the output GND and to the
Minus potential of the power supply
c. Pin 4 of the input connector provides an auxiliary voltage output, when the DIL-switch
positions 1 and 2 are set to "ON".
When DIL-switch positions 1 and 2 are set to "ON", never any external voltage
must be applied to pin 4!
The aux. output voltage is 5.5 V / 300 mA with TTL inputs and 24 V / 300 mA with options
HTLIN1 and HTLIN2.

With GV151, the desired output level (TTL/HTL) can be selected by setting the associated
position of the DIL switch to „ON“ (with the other position OFF).
Setting both TTL and HTL to ON at a time would result in HTL output.
For safety reasons, the default factory setting is always TTL like shown above.
