Operating Instructions tico 735 - Position Indicator

Introduction

Your Hengstler tico 735 Position Indicator is one model in a family of 1/8 DIN units which offers

breakthrough display technology as well as easy-to-program single-line parameters.

Designed to provide instant visual feedback regarding an application’s key input value, the tico 735 not

only has a 18 mm high LED display, but also the ability to change display colour based on process status

(programmable parameter in Operation Mode). Easy programming is made possible via a help function

and a secondary legend display.

This manual will guide you through the installation and wiring of your tico 735 unit with information on

proper panel mounting and rear terminal layout and wiring instructions. In addition, the instrument’s

operation and programming modes are thoroughly explained. The operation mode provides day to day

operation and allows editing of preset values. The Program Mode enables the configuration of various

parameters prior to initial operation. These parameters include

those for basic configuration as well as other settable features

which will enhance the functionality and usability of the device.

This manual also provides information on the tico 735 Position

Indicator’s product specifications and ordering information.

Features

•Awesome 18 mm high digit LED display

•Programmable colour change display based on an event

•Programmable help function and secondary legend display

•High and low alarm outputs

•Optional linear output relative to position

Safety Instructions

This symbol indicates passages in the text which you have to pay special

attention to so as to guarantee proper use and preclude any risk.

•The range of applications for this product are industrial processes and controls, where the

overvoltages applied to the product at the connection terminals are limited to values of the

overvoltage category II.

•This device is made and tested according to the valid standards of technics and has left the

factory in a perfect safety state. To keep this state and secure operation without danger, the user

has to observe the saftety and warning hints, contained in this operation manual.

•Assembling and mounting of electrical divices are restricted to be done by skilled electricians!

Skilled electrician is, who can judge the tasks deputed to him and foresee possible dangers, due

to his special education, knowledge and experience and consciousness of the pertinent

standards.

•Mount devices are only allowed to be operated when mounted.

•Finger protection at connection part of mount devices is to be secured when mounting!

•While mounting the device, it must be secured that the requirements, which are asked for the

device in the pertaining standards for safety, are not affected in a negative way, so reducing the

safety of this mount device.

•Mounting and assembling of device needs observation of the specifications of the local Energy

Suppliers.

•Before switching on, make sure that the power and control voltages are not exceeding the values

in accordance with the technical data.

•If it is to be assumed that operation without danger is not further possible, the device must be put

out of operation and secured from unintentional operation! It must be assumed that an operation

without danger is not further possible,

if the device shows damage

if the device stops functioning

after a longer stocking period under unfavourable conditions

after heavy strain during transportation.

•If by a failure or a malfunction of the device, endangering of men or animals or damaging of

facilities are possible, this must be avoided by additional safety measures (end switches,

protection devices and etc.).

•Before opening any cover, the device must be switched voltagefree.

•Hengstler Counters are intended for industrial applications.

•The mounting environment and nearby cabling have an important influence on the EMC (noise

radiation and noise immunity) of the counter. When putting into operation, the EMC of the whole

installation (unit) has to be secured. In particular, the relay outputs are to be protected from high

noise radiation by suitable wiring.

Installation

Panel mounting

The instrument can be mounted in a panel with a thickness of up to 12 mm. The cutout should be made based

on the recommended panel opening illustrated in the drawing below.

10096

tico 735

PGM RST

+ 0.5

Panel Cutout

Insert the unit in the panel through the cutout. Ensure that the panel gasket is not distorted and the instrument is

positioned squarely against the panel. Slide the mounting clamp into place on the instrument and push it

forward until it is firmly in contact with the rear face of the mounting panel and the tabs on the bracket arm are

seated in the mounting grooves on the side of the unit.

The electronic components of the instrument can be removed from the housing after installation without

disconnecting the wiring. To remove the components, grip the side edges of the panel and pull the instrument

forward. Take note of orientation of the unit for subsequent replacement in the housing.

Count Inputs

Terminal #2 is the connection for Input A, which is

used for channel A of an encoder input. Terminal #1 is

the connection for Inut B which is used for channel B of

an encoder input. The common connection for both

input A and input B is terminal #3.

Control/Digital Inputs

A contact closure or NPN signal can be used to

activate preconfigured functionality. Terminal #5 is

used for a remote reset function, while terminal #6 is a

security function, that when active, will prohibit entry

into Program Mode. Terminal #8 serves as the

common for both of these inputs.

Auxiliary Power Output

A 9-15 VDC for powering external sensors and

encoders up to 125 mA can be accessed by

connecting the positive supply side of the sensor to

Terminal #4 and the negative side to Terminal #8.

Linear Output

An option board may be installed that provides a 10 bit

linear output signal relative to the Position Value.

Terminal #12 is the positive side of the connection, and

Terminal #10 is the negative side. The default range of

the input is 4-20mA but can be changed via the front

panel to 0-20 mA, 0-10 VDC, 2-10 VDC, 0-5 VDC, or

1-5 VDC.

Power Supply Input

For an AC powered unit, Terminal #13 serves as the line

or hot side connection for AC powered units and as the

positive side for DC powered units. The neutral side for

AC powered units and the negative side for DC powered

units are connected to terminal #14.

Transistor Outputs

Your unit comes standard with 2 NPN outputs which are

activated by each of the alarms. Transistor Output 1,

which is tied to the High Alarm Value, is on Terminal #7.

Transistor Output 2, which is tied to the Low Alarm

Value, is on Terminal #9. Terminal #8 serves as the

common connection for both transistor outputs.

Relay Outputs

Your unit comes standard with a relay output which is

tied to the High Alarm Value. Terminal #19 is NC,

Terminal #20 is common, and Terminal #21 is NO. A

second relay output tied to the Low Alarm Value can be

added as an option at the time of order or later installed

in the field. Terminal #22 is NC, Terminal #23 is common

and Terminal #24 is NO.

Serial Communication

An RS-485 communication board, utilizing ASCII

protocol, can be installed as an option. Terminals #16

and #17 serve as the B and A connections respectively,

while terminal #18 is connected as the common.

Terminals 11 & 15 are not used and must not

be connected!
