PNOZ s7 safety relay

The unit meets the requirements of EN 60947-5-1, EN 60204-1 and VDE 0113-1. The con-tact expansion module is used to increase the number of instantaneous safety contacts available on a base unit. Base units are all safety relays with feedback loop monitoring.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.

For your safety

} Only install and commission the unit if you have read and understood these operating

instructions and are familiar with the applicable regulations for health and safety at work and accident prevention.

Ensure VDE and local regulations are met, especially those relating to safety.} Any guarantee is rendered invalid if the housing is opened or unauthorised modifica-tions are carried out.

Unit features

} Positive-guided relay outputs:

– 4 safety contacts (N/O), instantaneous– 1 auxiliary contact (N/C), instantaneous

} Safe separation of safety contacts 13-14, 23-24, 33-34 from all other circuits} LED for:

– Input status, channel 1– Input status, channel 2

– Switch status of the safety contacts– Fault

} Plug-in connection terminals (either spring-loaded terminal or screw terminal)

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

with PNOZsigma base unit:

} Dual-channel operation via PNOZsigma connectorwithout PNOZsigma base unit:

} Single-channel operation: one input circuit affects the output relays

Installation

Install contact expansion module without base unit:

} Ensure that the plug terminator is inserted at the side of the unit.Connect base unit and PNOZsigma contact expander module:

} Remove the plug terminator at the side of the base unit and at the contact expander

module} Connect the base unit and the contact expansion module using the connector supplied,

before mounting the units to the DIN rail.Control cabinet installation

} The safety relay 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 brack-et or end angle).} Push the unit upwards or downwards before lifting it from the DIN rail.

Wiring

Please note:

} Information given in the "Technical details" must be followed.

} Outputs 13-14, 23-24, 33-34, 43-44 are safety contacts; outputs 51 -52 are auxiliary

contacts (e.g. for display).} Auxiliary contact 51-52 should not be used for safety circuits!

} To prevent contact welding, a fuse should be connected before the output contacts (see

technical details).} Calculation of the max. cable length lmax in the input circuit:

Imax =

RlmaxRl / km

Rlmax = max. overall cable resistance (see technical details)

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.

Diagnostics: Plug terminator not connected

} Remedy: Insert plug terminator, switch supply voltage off and then on

again.

Faults - malfunctions

} Contact malfunctions: If the contacts have welded, reactivation will not be possible after

the input circuit has opened.

Service life graph

The service life graphs indicate the number of cycles from which failures due to wear must be expected. The wear is mainly caused by the electrical load; the mechanical load is negli-

gible.

Example

} Inductive load: 0,2 A} Utilisation category: AC15

} Contact service life: 2,000,000 cycles

Provided the application requires fewer than 2,000,000 cycles, the PFH value (see techni-cal details) can be used in the calculation.

To increase the service life, sufficient spark suppression must be provided on all output contacts. With capacitive loads, any power surges that occur must be noted. With contac-tors, use freewheel diodes for spark suppression.

Safety characteristic data

tacts, instan-taneous

All the units used within a safety function must be considered when calculating the safety characteristic data.

The PFH value depends on the switching frequency and the load on the relay output. If the service life graphs are not accessible, the stated PFH value can be used irrespective of the switching frequency and the load, as the PFH value already considers the relay's B10d val-ue as well as the failure rates of the other components.
