Original operating
instructions
1.1 3/25
1 Foreword
These operating instructions are intended for installers and operators and
should be kept for future reference. Read these operating instructions carefully
and make sure that you have fully understood the contents before installing or
working with the safeCAP SC30. The operator is responsible for validating the
entire safety system.
2 Safety
2.1 Notes and symbols used
Warning notes in relation to personal injury / material damage are formulated
according to the "SAFE” principle. This means they contain information on the
type and source of the hazard, potential consequences as well as how to avoid
and avert danger. The following hazard classifications apply in the safety notes:
DANGER
Danger designates a hazardous situation, which, if ignored, will lead to
death or serious injury. The symbol next to the warning indicates the type
and source of the danger.
WARNING
Warning designates a hazardous situation, which, if ignored, may lead to
death or serious injury. The symbol next to the warning indicates the type
and source of the danger.
CAUTION
Caution designates a hazardous situation, which, if ignored, may lead to
injury. The symbol next to the warning indicates the type and source of the
danger.
NOTICE
Notice designates a situation, which may cause material damages and
impair the product’s function if attention is not paid.

►Instructions for action
All instructions to be followed within a procedure are always
listed in chronological order.
■List
2.2 General safety
All work on electrical systems or operating equipment may only be carried out
by a specially qualified electrician according to the applicable electrotechnical
regulations.
The safety of the system in which the SENSORswitch is integrated is the
responsibility of the operator.
WARNING
Dangerous machine movement
The functioning two-hand control only protects operators from dangerous
machine movements.
4Protect the machine danger zone against unauthorized access with
additional safety devices.
2.3 Personnel qualifications
A qualified electrician is a person with suitable technical training, expertise and
experience as well as knowledge of relevant standards, who can evaluate the
work assigned to them correspondingly and recognize potential risks.
The following general safety notes for working with electrical energy must be
observed:

WARNING
Improper work on electrical systems!
Electric shock can result in death or life-threatening injuries.
4Before working on electrical systems, disconnect them from their
voltage supply and secure them against being switched on again.
4Wear appropriate personal protective equipment (PPE).
4Defects that are ascertained, such as damaged or loose cables, must
be remedied immediately.
2.4 Intended use
Combined with the safety relay, safeCAP SC30 ensures safety-related release
and interruption of a safety circuit. safeCAP SC30 is used to protect people
from work machines with dangerous closing movements. safeCAP SC30 is
tested with the following safety relays: MCR 225, 3SK1, 3RK3 and PNOZ s6.
Connection of MCR 225, 3SK1 and PNOZ s6 is described as an example in
the instructions. The operator is responsible for safety-related release and
interruption of the safety circuit.
2.5 Reasonably foreseeable misuse
Any use other than as specified Chapter 2.4, "Intended use" or extending
beyond this is deemed to be improper.
The switch is not suitable for:
■use as a two-hand control without the aforementioned relay or in case
of use of an equivalent t-network, the independent calculation of the
performance level in accordance with ISO 13849-1:2015.
■use as a two-hand control without validation of the entire system.
■use with cables between SC30 and safety relay with a length exceeding
30 m.
■use as a two-hand control in combination with another switch.
■use as an emergency stop command device.
■use in potentially explosive atmospheres.
■use outdoors.

2.6 Determining the lifetime and validating the
entire system
The following steps are mandatory.
■Determine the real parameters of the system.
4Required performance level
4dop
4hop
4tcycle
■The operator must verify that the lifetime TM is not exceeded.
■Validate the entire system.
■Observe the safety considerations in the operating instructions of the safety
relay.
2.7 Example calculation
The following values are only examples and must be replaced with your own
values.
■Performance level e must be achieved.
■dop = 250 d
■hop = 24 h
■tcycle = 10 s
nop [cycles / year]
nop = (dop * hop *3600 s) / tcycle
nop = 250 d / y * 24 h / d * 3600 s / h / 10 s / cycle = 2,160,000 cycles / year
According to the operating instructions, the relay has a lifetime of approximately
20 million cycles before a dangerous failure can occur.
TM = 20,000,000 / nop
TM = 20,000,000 / 2,160,000 = 9.3 years
According to this calculation, the relay has to be replaced after 9.3 years.
For other relays, values such as B10D or T10D can be specified. These values are
not considered here and can be requested from CAPTRON.

WARNING
Improper safeCAP SC30 assembly!
An improperly assembled or non-functional two-hand control device can
result in death or life-threatening injuries.
4Select mounting surfaces for the safeCAP SC30 based on the
dimensions and spacing specified in DIN EN ISO 1385:2019.
4Protect safeCAP SC30 against unintended actuation, for example
SCP-6.
4Before working on the machine, check safeCAP SC30 for proper
function.
The safety distance between the machine and the two-hand control is
calculated based on the following formula.
S = K (t1 + t2) + C
■(S) Safety distance
■(K) Expected approach velocity of the human body or body parts. In
accordance with EN ISO 13855:2010
4Walking speed 1600 mm/s
4Grasping speed 2000 mm/s
■(t1) Time the safety equipment needs to respond.
■(t2) Time the machine needs after receiving the safety equipment signal
until the machine stops.
■(C) Additional horizontal distance from the danger zone in mm in
accordance with EN ISO 13855:2010
