JX2-CNT1 1.1 Generally Valid Safety Instructions
Jetter AG 11
TableofContents 1 Safety Instructions
1.1 Generally Valid Safety Instructions
The JX2-CNT1 module complies with the applicable safety regulations and
standards. Special emphasis was given to the safety of the users.
Of course, the user should adhere to the following regulations:
• pertinent accident prevention regulations;
• accepted safety rules;
• EC guidelines and other country-specific regulations.
1.1.1 Intended Conditions of Use
The intended conditions of use include operation in accordance with the user
manual.
The JX2-CNT1 can be connected as peripheral module to the Jetter system bus.
The JX2-CNT1 module is used for position capturing and for counting events.
In the case of position capturing signals from an incremental encoder (via dual-
channel counter) or an absolute encoder (SSI) are evaluated. The single-channel
counter is for counting events.
The module JX2-CNT1 is supplied with power from the Jetter system bus, that is, by
the basic unit - the controller - in the case of centralized arrangement. In the case of
remote arrangement by the power supply module JX2-PS1.
The supply voltage of the JX2-CNT1 module is DC 5 V. This operating voltage is
classified as SELV (Safety Extra Low Voltage). The JX2-CNT1 module is therefore
not subject to the EU Low Voltage Directive.
The JX2-CNT1 module may only be operated within the limits of the stated data (for
more information refer to chapter 5 "Technical Data", page 27).
The JX2-CNT1 module is used to control machinery, such as conveyors, production
machines, and handling machines.
1.1.2 Usage Other Than Intended
The JX2-CNT1 module must not be used in technical systems which to a high degree
have to be fail-save, e.g. ropeways and aeroplanes.l
If the JX2-CNT1 module is to be run under ambient conditions, which differ from the
conditions mentioned in chapter 4 "Operating Conditions", page 23, the
manufacturer is to be contacted beforehand.

1 Safety Instructions JetWeb
12 Jetter AG
1.1.3 Who is Permitted to Operate the
JX2-CNT1 Module?
Only instructed, trained and authorized persons are permitted to operate the JX2-
CNT1 module.
Mounting and backfitting may only be carried out by specially trained personnel, as
specific know-how will be required.
1.1.4 Modifications and Alterations to the
Module
For safety reasons, no modifications and changes to the JX2-CNT1 module
and its functions are permitted.
Any modifications to the JX2-CNT1 module not expressly authorized by the
manufacturer will result in a loss of any liability claims to Jetter AG.
The original parts are specially designed for the JX2-CNT1 module. Parts and
equipment from other manufacturers are not tested on our part, and are,
therefore, not released by Jetter AG.
The installation of such parts may impair the safety and the proper functioning of the
JX2-CNT1 module.
Any liability on the part of Jetter AG for any damages resulting from the use of non
original parts and equipment is excluded.
1.1.5 Repairing and Servicing the
JX2-CNT1 Module
The JX2-CNT1 module must not be repaired by the operator itself. The JX2-CNT1
module does not contain any parts which can be repaired by the operator.
If the JX2-CNT1 module needs repairing, please send it to Jetter AG.
The JX2-CNT1 module is maintenance-free. Therefore, absolutely no inspection or
maintenance works are required for the operation of this device.
Transport: Only by personnel with knowledge in handling
electrostatically sensitive components.
Installation: Only by specialists with training in electrical
engineering.
Commissioning: Only by specialists with extensive knowledge of, and
experience with, electrical engineering / drive
technology.

Jetter AG 13
1.1.6 Decommissioning and Disposal of the
JX2-CNT1 Module
Decommissioning and disposal of the JX2-CNT1 module are subject to the
environmental legislation of the respective country in effect for the operator's
premises.

1.2 Ensure Your Own Safety
1.2.1 Malfunctions
1.2.2 Information Signs and Labels
Disconnect the JX2-CNT1 module from the mains to carry out
maintenance work. By doing so, you will prevent accidents resulting from
electric voltage and moving parts.
Safety and protective devices, e.g. the barrier and cover of the terminal
box must never be shunted or by-passed.
Dismantled protective equipment must be reattached prior to
commissioning and checked for proper functioning.
Malfunctions or other damages are to be reported to a responsible person
at once.
Safeguard the JX2-CNT1 module against misuse or accidental use.
Only qualified experts are allowed to carry out repairs.
Markings, information signs, and labels always have to be observed and
kept readable.
Damaged or unreadable information signs and labels have to be replaced.

JX2-CNT1 1.3 Instructions on EMI
Jetter AG 15
1.3 Instructions on EMI
The noise immunity of a system corresponds to the weakest component of the
system. For this reason, correct wiring and shielding of cables is of paramount
importance.
Important!
Measures for increasing immunity to interference:
Attach the JX2-CNT1 module to a DIN rail acc. to EN 50022-35 x 7.5.
Connect the JX2-CNT1 module to the controller or the power supply
module JX2-PS1 via Jetter system bus.
Connect the JX2-CNT1 module to the Jetter system bus by directly
plugging it into a JX2 module (not through a cable).
The system bus can be extended by means of a cable.
Follow the instructions given in Application Note 016 "EMC-Compatible
Installation of the Electric Cabinet" published by Jetter AG.
The following instructions are excerpts from Application Note 016:
On principle, physical separation should be maintained between signal
and power lines. We recommend spacings greater than 20 cm. Cables and
lines should cross each other at an angle of 90°.
Shielded cables must be used for the following lines:
Analog lines, data lines, motor cables coming from inverter drives (servo
output stage, frequency converter), lines between components and
interference suppressor filter, if the suppressor filter has not been placed
at the component directly.
Shield cables at both ends.
Unshielded wire ends of shielded cables should be as short as possible.
The entire shield must, in its entire perimeter, be drawn behind the
isolation, and then be clamped under an earthed strain relief with the
greatest possible surface area.
When male connectors are used:
The shield (impedance shielding) must, in its entire perimeter, be drawn
behind the shielding clamp of the metallized connector housing,
respectively of the EMC gland bushing, its greatest possible surface area
being clamped under a strain relief.

16 Jetter AG
Fig. 1: Shielding of SUB-D connectors in conformity with EMC standards.
Fig. 2: Shielding of screw terminals in conformity with the EMC standards.
Only use metallized connectors, e.g. SUB-D with metallized housing.
Make sure that the strain relief is directly connected with the housing here
as well (see Fig. 1).
If the shield cannot be attached to the connector, for example, with a screw
type terminal:
It is important that shield and strain relief are highly conductive and directly
connected to a grounded surface with the greatest possible surface area.
When doing so, grounding must be implemented in a way that the
unshielded portion of the cable is as short as possible (refer to Fig. 2).

Important!
To avoid malfunctions the following must be ensured:
• The shielding must be clamped under a strain relief with the greatest possible
surface area.
• The connection between shielding and ground must be electrically conducting.
• The length of unshielded conductor ends must not exceed 8 cm (refer to
Fig. 2).

2Introduction
This manual contains important information on how to transport, erect, install,
operate, maintain and repair the non-intelligent expansion module JX2-CNT1 with
firmware version 3.02 or higher.
2.1 Product Description
The JX2-CNT1 module is for position capturing and for counting events. In the case
of position capturing signals from an incremental encoder (via dual-channel counter)
or an absolute encoder (SSI) are evaluated. The single-channel counter is for
counting events.
The position obtained from position capturing can be evaluated in the application
program or be sent via system bus as set position (master position) to an axis
controller by Jetter AG. The single-channel counter is used e.g. as workpiece
counter.
