Safety
Intended use
The contact expansion module PZE 9P meets the requirements of EN 60947-5-1 and EN
60204- 1. It is an expansion module for increasing 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 max. achievable safety level depends on the base unit. The expansion module may not
exceed this. The safety-related characteristic values stated under safety-related character-
istic data [ 23] can only be achieved if the base unit also exhibits these safety charac-
teristic values.
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 device, a safety assessment in accordance with the Machinery Directive is
required.
The product as an individual component fulfils the functional safety requirements in accord-
ance with EN ISO 13849 and EN 62061. However, this does not guarantee the functional
safety of the overall plant/machine. To achieve the relevant safety level of the overall plant/
machine’s required safety functions, each safety function needs to be considered separ-
ately.

laws, directives and standards.
It is the company’s responsibility only to employ personnel who
}Are familiar with the basic regulations concerning health and safety / accident prevention,
}Have read and understood the information provided in the section entitled Safety
}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

}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-related
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.

Safety features
The unit meets the following safety requirements:
}The contact expansion module expands an existing circuit. As the output relays are mon-
itored via the base unit's feedback loop, the safety functions on the existing circuit are
transferred to the contact expandsion 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 9P 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" are lit.
}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 (35 mm).
}When installed vertically: Secure the unit by using a fixing element (e.g. retaining bracket
or 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; out-
put 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 length 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 wiring with a temperature stability of 60/75 °C.
}To prevent EMC interferences (particularly common-mode interferences) the measures
described in EN60204-1 must be executed. This includes the separate routing of cables
of the control circuits (input, start and feedback loop) from other cables for energy trans-
mission or the shielding of cables, for example.
}Adequate protection must be provided on all output contacts with capacitive and inductive
loads.
}Do not switch low currents using contacts that have been used previously with high cur-
rents.
}777140, 787140 units or 777148, 787148 units, when the supply voltage is connected via
B1 and B2: The power supply must meet the regulations for extra low voltages with pro-
tective electrical separation (SELV, PELV).

Operation
When the relay outputs are switched on, the mechanical contact on the relay cannot be
tested automatically. Depending on the operational environment, measures to detect the
non-opening of switching elements may be required under some circumstances.
When the product is used in accordance with the European Machinery Directive, a check
must be carried out to ensure that the safety contacts on the relay outputs open correctly.
Open the safety contacts of the contact expansion module (switch off outputs of the base
unit) and start the base unit again so that the internal diagnostics can check that the safety
contacts open correctly

Faults – Interference
By closing or interrupting the input circuit you can check whether the unit switches on or off
correctly.
For safety reasons, the unit cannot be started if the following faults are present:
}Contact malfunction: As the contact block is connected to a base unit,
reactivation will not be possible if the contacts have welded after the input circuit has
opened.
