ISK 77 / SPK 77 Inductive signal transmission system

2. General safety regulations and protective measures

• The manufacturer and users of the plant / machine on which the protection is being used are responsible
for implementing and following all applicable safety regulations and rules.
• When used in conjunction with the higher-order controller, the protection guarantees functional safety,
but not the safety of the entire plant / machine. The safety of the entire plant / machine must, therefore,
be assessed in accordance with machinery directive 2006/42/EC or appropriate product norm before
using the device.
• The operating manual must always be available at the place of installation of the protection. They must
be read thoroughly and observed by all persons involved in the operation, maintenance and servicing of
the protection.
• The protection must only be installed and commissioned by professionals familiar with these operating
instructions and the applicable operational safety and accident prevention regulations. All of the instruc-
tions provided in these operating instructions must be observed and followed.
• All electrical work must only be performed by skilled electricians. All relevant electrical engineering and
Employer's Liability Insurance Association safety regulations must be observed.
• During work on the switching unit, it is to be switched to zero potential, checked to ensure that it is at
zero potential and protected against being restarted.
• If the potential-free contact of the relay output is supplied externally with a dangerous voltage, make
certain that this voltage is switched off during work on the switching unit.
• The switching unit does not contain any components that require servicing by the user.
Unauthorised conversions and repairs made to the switching unit will void all guarantees and the
manufacturer's liability.
• The protection system is to be professionally inspected at appropriate intervals and be documented in
such a way that it is comprehensible at all times.

Safety advice

• The switching unit enables operation at 24 V. Connecting the operating voltage to the wrong terminals
can destroy the switching unit.
• For capacitive and inductive loads, ensure adequate protective circuits.
The switching unit complies with EN ISO 13849 "Safety-related parts of control systems",
category 3. To meet category 3 requirements, the switching unit is designed redundantly with
two switching outputs per channel that monitor one another. Device variant R (semiconductor
relay output) is designed in accordance with category 2 with test input.
The requirements of EN 12978 "Safety devices for power operated doors and gates" and EN 12453 "Safety
in use of power operated gates" are also fulfilled.
For the design of the safety system to conform to engineer standards, the plant / machine must be profes-
sionally inspected at appropriate intervals for proper function. The inspection must be documented in such
a way as to be comprehensible at all times.
For the design of the safety system to conform to engineer standards acc. to EN 13849 category 2 for device
variant R, the safety system must be tested prior to each dangerous movement of the plant / machine.
Without testing, the operation or wiring of the safety relay does not satisfy these safety requirements.
The manufacturer assumes no liability in the event of non-observance or intentional abuse.
