Safety
Intended use
The contact expansion module PZE 9 meets the requirements of EN 60947-5-1, EN
60204-1 and VDE 0113-1. It is used to increase the number of contacts available on a base
unit. Base units are all
}Safety relays with feedback loop
}Programmable safety systems with feedback loop
The category that can be achieved in accordance with EN ISO13849-1 depends on the
category of the base unit. The contact expansion module may not exceed this.
The following is deemed improper use in particular:
}Any component, technical or electrical modification to the product
}Use of the product outside the areas described in this manual
}Use of the product outside the technical details (see Technical details [ 12]).
NOTICE
EMC-compliant electrical installation
The product is designed for use in an industrial environment. The product
may cause interference if installed in other environments. If installed in other
environments, measures should be taken to comply with the applicable
standards and directives for the respective installation site with regard to in-
terference.
Safety regulations
Safety assessment
Before using a unit it is necessary to perform a safety assessment in accordance with the
Machinery Directive.
Functional safety is guaranteed for the product as a single component. However, this does
not guarantee the functional safety of the overall plant/machine. In order to achieve the re-
quired safety level for the overall plant/machine, define the safety requirements for the
plant/machine and then define how these must be implemented from a technical and organ-
isational standpoint.

Use of qualified personnel
The products may only be assembled, installed, programmed, commissioned, operated,
maintained and decommissioned by competent persons.
A competent person is someone who, because of their training, experience and current pro-
fessional activity, has the specialist knowledge required to test, assess and operate the
work equipment, devices, systems, plant and machinery in accordance with the general
standards and guidelines for safety technology.
It is the company’s responsibility only to employ personnel who:
}Are familiar with the basic regulations concerning health and safety / accident preven-
tion
}Have read and understood the information provided in this description under "Safety"
}And have a good knowledge of the generic and specialist standards applicable to the
specific application.
Warranty and liability
All claims to warranty and liability will be rendered invalid if
}The product was used contrary to the purpose for which it is intended
}Damage can be attributed to not having followed the guidelines in the manual
}Operating personnel are not suitably qualified
}Any type of modification has been made (e.g. exchanging components on the PCB
boards, soldering work etc.).
Disposal
}In safety-related applications, please comply with the mission time TM in the safety-re-
lated characteristic data.
}When decommissioning, please comply with local regulations regarding the disposal of
electronic devices (e.g. Electrical and Electronic Equipment Act).
For your safety
The unit meets all the necessary conditions for safe operation. However, please note the
following:
}Note for overvoltage category III: If voltages higher than low voltage (>50 VAC or >120
VDC) are present on the unit, connected control elements and sensors must have a
rated insulation voltage of at least 250 V.

– 1 auxiliary contact (N/C), instantaneous
}LED display for:

– Switch status of the safety contacts
}Connection for feedback loop
}Operation: Single or dual-channel
}See order reference for unit types
Safety features
The unit meets the following safety requirements:
}The contact expander module expands an existing circuit. As the output relays are
monitored via the base unit's feedback loop, the safety functions on the existing circuit
are transferred to the contact expander module.
}The safety function remains effective in the case of a component failure.
}Earth fault in the feedback loop:
Detected, depending on the base unit that is used.
}Earth fault in the input circuit:
The output relays de-energise and the safety contacts open.

Function description
The contact expansion module PZE 9 is an add-on device without delay-on de-energisa-
tion. It is used to expand a safety circuit. The contact expansion module is driven by a base
unit (e. g. emergency stop relay). When operating voltage is supplied the "POWER" LED
will light.
}Functional procedure once the input circuit is closed (e.g. safety contacts on the base
unit are closed):
– Safety contacts 13-14, 23-24, 33-34, 43-44, 53-54, 63-64, 73-74 and 83-84 close,
auxiliary contact 91-92 opens.
– The LEDs "CH.1" and "CH.2" illuminate.
}Functional procedure once the input circuit is opened (e.g. safety contacts on the base
unit are opened):
– Safety contacts 13-14, 23-24, 33-34, 43-44, 53-54, 63-64, 73-74 and 83-84 are
opened redundantly, auxiliary contact 91-92 is closed.
– The LEDs "CH.1" and "CH.2" go out.

Installation
}The unit should be installed in a control cabinet with a protection type of at least IP54.
}Use the notch on the rear of the unit to attach it to a DIN rail.
}Ensure the unit is mounted securely on a vertical DIN rail (35 mm) by using a fixing ele-
ment (e.g. retaining bracket or an end angle).
Wiring
Please note:
}Information given in the "Technical details [ 12]" must be followed.
}Outputs 13-14, 23-24, 33-34, 43-44, 53-54, 63-64, 73-74, 83-84 are safety contacts;
output 91-92 is an auxiliary contact (e.g. for display).
}Do not use auxiliary contact 91-92 for safety circuits!
}Do not connect undesignated terminals.
}To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [ 12]).
}Calculation of the max. cable runs lmax in the input circuit:
Rlmax
Rl / km
Imax =
Rlmax = max. overall cable resistance (see Technical details [ 12])
Rl/km = cable resistance/km
}Use copper wire that can withstand 60/75°C.
}Sufficient fuse protection must be provided on all output contacts with capacitive and in-
ductive loads.
}Do not switch low currents using contacts that have been used previously with high cur-
rents.
}On 24 VDC devices:
The power supply must comply with the regulations for extra low voltages with protect-
ive electrical separation (SELV, PELV) in accordance with VDE 0100, Part 410.
}Ensure the EMC requirements of IEC 60204-1 are met.
