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

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.

+ 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!
