Operating Instructions tico 735 - Elapsed Timer
Introduction
Your Hengstler tico 735 Elapsed Timer 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
Elapsed Timers’s transistor and relay outputs, product
specifications and ordering and warranty information.
Features
•Awesome 18 mm high digit LED display
•Programmable colour change display based on an
event
•Programmable help function and secondary legend display
•Programmable for single input or cumulative operation
•Choice of NPN or PNP primary input
•Standard outputs: one NPN transistor & one relay
•Front panel reset enable and preset lockout
•Optional RS-485 plug in card

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
45
+ 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.

Timing Inputs
Terminal #2 is the connection for input A, which is the
start signal for time accumulation. The common
connection for input A 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 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.
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 an NPN output which is
activated by the preset. Transistor output 1, which is tied
to the Set Value, is on Terminal #7. Terminal #8 serves
as the common connection for the Transistor output.
Relay Outputs
Your unit comes standard with a relay output which is
tied to the Set Value. Terminal #19 is NC, Terminal #20
is common and Terminal #21 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 1,9,10,11,12,15,22,23 & 24 are not
used and must not be connected!
