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. Non­conforming 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 8). The device is not
suitable for operation in explosion-proof areas or areas which are excluded by the EN 61010-1
standard.

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 voltage­sources.

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 temperature­ranges. 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 cross­sections for wiring are described in the Technical Specifications (see chapter 8).

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.

2. Introduction

The IT210 is a universal interface using with incremental measuring systems.
The device allows the solution of the following problems:

• Level conversion (RS-422, HTL single ended, HTL differential, TTL and vice versa)

• Division of two-track A / B pulses with adjustable ratio 1: 1 to 1: 2048

• Division of the Z pulse with adjustable ratio 1: 1 to 1: 256

• External HTL signals for various functions

• Implementation between the two types of representations for the direction of rotation

(A/B 90 °, A/B Dir and vice versa, Division possible)

All settings are made on the DILL switches on the housing. The device consists of a compact
housing with screw terminals and can be mounted on a DIN rail.Block diagram

4. Terminal Assignments and Connections

The input pulses are connected to the screw terminals X4. The unused inputs must remain open
(HTL Single Ended as opposed to HTL Differential), or possibly be completed (unused Z-track in
RS-422 or HTL Differential format). On the X4 screw terminal 9, 8, an auxiliary voltage of
+ 5.5 V / 250 mA is available for the encoder supply.

Depending on the DIL switch setting, the pulses are available at the outputs of the screw
terminal X3 in HTL or RS-422 format and are independent of the connected format. In the HTL
setting, the height of the pulse level at the push-pull outputs corresponds to the input voltage
at the supply input X1.

The Control HTL inputs (reset of the internal dividers) to X2 have PNP characteristics and must
be switched against + to activate the function. The supply voltage is connected to X1.

It should be noted that all inputs and outputs refer to the same ground potential GND, which at
the same time represents the negative pole of the device supply. At any time, the total
transmission characteristics of encoder, external components and capacity of the cable must
ensure proper signals at the input terminals of the unit, with respect to the levels, the shape
and the phase displacement A/B.
