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 reserves 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 have 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). 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 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.

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.

Overvoltage 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.

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 SSI display device is designed for panel mounting. It is universally applicable, with its

intuitive operation and the extensive features.

2.1. Operation mode

All functions are can be configured in the parameter menu.

The device can be set to one of the following operation modes:

•MASTER

-The clock for the connected sensor is produced

-The both clock terminals (CLK, / CLK) are configured as outputs in this case

•SLAVE

-The clock for the encoder is generated by an external device (the SSI master).

-The both clock terminals (CLK, / CLK) are configured as inputs in this case

3. Electrical Connections

The terminal screws should be tightened with a slotted screwdriver (blade width 2mm).

3.1. DC Power Supply

The unit accepts DC supply from 18 to 30 V at the terminals 1 and 2. The power consumption

depends on the level of the supply voltage with approx. 100 mA and the additional current

required at the Auxiliary Voltage Output.

All GND terminals are internally interconnected.

3.2. Auxiliary Voltage Output

Terminal 3 and 4 provide an auxiliary output for supply of sensors and encoders.

The output voltage depends on the power supply.

The encoder voltage is approx. 1 V lower than the power supply voltage at terminal 1 and 2

and should be loaded with max. 250 mA.

The auxiliary voltages output is switchable from 24 VDC to 5 VDC.

3.3. SSI-Inputs

At Terminal 5, 6, 7 and 8, the connection is available for SSI signals. The basic settings must

be set in the menu SSI PROPERTIES.

Wiring for MODE Master:

Wiring for MODE Slave:

3.4 Control Inputs

The three control inputs at terminal 10, 11 and 12 have HTL PNP characteristics.

In the COMMAND MENU the programmable functions for the control inputs can be assigned.

Available functions are: reset the display value, display switching, locking the touch screen or

release the lock function of the control or relay outputs.

Wiring of the control inputs:

Unconnected PNP inputs are always “LOW” and unconnected NPN inputs are always “HIGH”.

All inputs are designed to receive impulses from electrical impulse sources.

Notice for mechanical switching contacts:

When exceptionally mechanical contacts are used, please connect an external capacitor

between GND (-) and the corresponding input (+). A capacity of 10 µF will reduce the input

frequency to

20 Hz and miscounting due to contact bouncing will be eliminated.

3.4. Relay-Output

Two relay outputs with potential-free changeover contacts are available at terminal 27, 28, 28,

30, 31 and 32. Switching conditions can be set in the PRESELECTION MENU. The switching

states are displayed (display with unit and status bar) as K1 and K4.

DC-switching capacity max 150 VAC/ max 2 A / 50 W
