On safety
2.2 Applications of the device
The V200 WS/V300 WS safety camera system is an item of electro-sensitive protective
equipment (ESPE). The physical resolution is 20 mm at a maximum protective field width
of 1000 mm, and at a maximum protective field height of also 1000 mm.
The device is a Type 3 ESPE (V300 WS) or type 2(V200 WS) according to IEC 61496@1
and IEC/TR 61496@4and is therefore allowed for use with controls in category 3 according
to EN 954@11).The device is suitable for hazardous point protection (hand protection).
Access to the hazardous point must be allowed only through the protective field. As long as
the hazardous point is occupied, the system must not start. Refer to section 3.3
“Application examples” on page 12 for an illustration of the protection modes.
Only use the safety camera system as an indirect protective measure!
An opto-electronic protective device provides indirect protection, e.g. by switching off the
power at the source of the hazard. It cannot provide protection from parts thrown out, nor
from emitted radiation. Transparent objects are not detected.
Depending on the application, mechanical guards may be required in addition to the safety
camera system.
The safety camera system is only intended for use in industrial environments. When used
in residential areas it can cause radio interferences.
2.3 Correct use
The V200 WS/V300 WS safety camera system must be used only as defined in section 2.2
“Applications of the device”. It must be used only by qualified personnel and only on the
machine where it has been installed and initialised by qualified safety personnel in
accordance with these operating instructions.
If the device is used for any other purposes or modified in any way — also during mounting
and installation — any warranty claim against SICK AG shall become void.
1) Only valid for the assumption of conformity until 29.11.2009. From then on it will only be allowed to use the
successor EN ISO 13849@1:2006.

2.4 General safety notes and protective measures
Pay attention to the safety notes!
Please observe the following procedures in order to ensure the correct and safe use of the
V200 WS/V300 WS safety camera system.
The national/international rules and regulations apply to the installation, use and
periodic technical inspections of the safety camera system, in particular
–Machinery Directive 98/37/EC
–Work Equipment Directive 89/655/EEC
–the work safety regulations/safety rules
–other relevant safety regulations
Manufacturers and operators of the machine on which the safety camera system is used
are responsible for obtaining and observing all applicable safety regulations and rules.
The notices, in particular the test regulations (see section 7.1 “Test notes” on page 40)
of these operating instructions (e.g. on use, mounting, installation or integration into the
existing machine controller) must be observed.
The tests must be carried out by qualified safety personnel or specially qualified and
authorised personnel and must be recorded and documented to ensure that the tests
can be reconstructed and retraced at any time.
Changes to the configuration of the devices can degrade the protective function. After
every change to the configuration you must therefore check the effectiveness of the
protective device. The person who makes the change is also responsible for the correct
protective function of the device.
The light beams from the camera may be deflected by reflective surfaces. This can
result in failure to identify an object. For this reason reflective surfaces on the reflective
tape or in the protective field are not allowed.
The operating instructions must be made available to the operator of the machine where
the V200 WS/V300 WS safety camera system is fitted. The machine operator is to be
instructed in the use of the device by qualified safety personnel and must be instructed
to read the operating instructions.
The external voltage supply of the devices (SELV) must be capable of buffering brief
mains voltage failures of 20 ms as specified in EN 60204@1. Suitable power supplies

3.4 Configurable functions
This section describes the functions of the V200 WS/V300 WS safety camera system that
can be configured.
Test the protective device after any changes!
After each modification to the protective device or its connection, you must check the
whole protective device for effectiveness (see section 7.1 “Test notes” on page 40).
3.4.1 Restart interlock
The V200 WS/V300 WS has an internal restart interlock. The dangerous state of the
machine ()is interrupted on a protective field interruption (), and is not re-enabled ()
until the operator presses the reset button.
If you use the V200 WS/V300 WS without internal restart interlock, then you must
implement the restart interlock externally, i.e. machine-side.
Do not confuse the restart interlock with the starting interlock on the machine. The start
interlock prevents the machine starting after switching on. The restart interlock
prevents the machine starting again after an error or an interruption in the light path.
When using the V200 WS/V300 WS, you can implement the restart interlock in two
different ways:
With the internal restart interlock of the V200 WS/V300 WS:
The V200 WS/V300 WS controls the restart.
With the restart interlock of the machine (external):
The V200 WS/V300 WS has no control over the restart.

the external restart interlock, the users and operators of the machine will be at acute risk
of injury.
Reset
If you activate the restart interlock on the V200 WS/V300 WS (internal) and also realise a
restart interlock on the machine (external), then each restart interlock gets its own button.
When actuating the reset button (for the internal restart interlock) …
the V200 WS/V300 WS activates the output signal switching devices.
switches the V200 WS/V300 WS to green.
Only the external restart interlock prevents the machine from restarting. After pressing the
reset button for the V200 WS/V300 WS, the operator must also press the restart button
for the machine. If the reset button and the restart button are not pressed in the specified
sequence, the dangerous state must remain disrupted.
The reset button prevents the accidental and inadvertent operation of the external restart
button. The operator must first acknowledge the safe state with the reset button.
The electrical connection of the reset button is described in section 5.3 on page 31. The
configuration of the internal restart interlock is described in section 8.2 “Internal restart
interlock” on page 43.

3.4.2 External device monitoring (EDM)
The V200 WS/V300 WS has external device monitoring. If you activate the external device
monitoring, then the V200 WS/V300 WS checks whether the contactors are actually de-
energized when the protective device triggers. If, after an attempted Reset/Restart, the
EDM does not detect a response from the switched device within 300 ms, the EDM will
deactivate the output signal switching devices again. In this case the safety camera
system signals as follows:
The system remains at red. The status LED   illuminates.
The status LED   flashes continuously (short on/long off).
The diagnostics LED 2flashes.
If the system is unable to change to a safe operational state (e.g. after contactor failure),
the system locks and shuts down completely (“lock@out”, see page 47). The electrical
connection for the external device monitoring is described in section 5.3 on page 31. The
configuration of the external device monitoring is described in chapter 8 “Configuration”
on page 42ff.

4Mounting
This chapter describes the preparation and completion of the mounting of the
V200 WS/V300 WS safety camera system. Mounting requires the following steps:
checking the dimensions of the protective field (see below)
determination of the safety distance (see page 18ff.)
mounting of the camera (see page 21ff.)
mounting of the reflective tape (see page 27)
The following steps are necessary after mounting and installation:
completion of the electrical connections (see chapter 5 on page 29ff.)
testing the installation (see section 7.1 on page 40)
4.1 Checking the dimensions of the protective field
Only use the V200 WS/V300 WS safety camera system if the ratio allowed for the
lengths of the sides of the protective field can be met!
If the maximum ratio of the lengths of the sides is exceeded, the safety camera system
may not operate correctly. This would mean that the operator is at risk.
The lengths of the sides of a protective field monitored by a V200 WS/V300 WS must
not be shorter than 0.40 m and not longer than 1 m.
The ratio of the lengths of the sides of a protective field monitored by a
V200 WS/V300 WS must not exceed 2:1.
If you need a larger protective field, you can mount two V200 WS/V300 WS facing in
opposite directions. In this way you can generate two overlapping protective fields (see
6.1.2 “Application with large protective field (2 × V200 WS/V300 WS)” on page 37).

4.2 Determining the safety distance
The safety camera system must be mounted with an adequate safety distance between
the protective field and the hazardous point. This ensures that the hazardous point can
only be reached after the dangerous state of the machine has been completely stopped.
No protective function without sufficient safety distance!
The reliable protective effect of the safety camera system depends on the safety camera
system being mounted with the correct safety distance from the hazardous point.
If mounted vertically, the protective field is from the centre of the camera lens to the edge
of the reflective tape that is closest to the hazardous point. (The reference point for the
safety distance Sis therefore not the middle of the reflective tape. Cf. Fig. 9.)
If the protective field is at an angle, pay special attention to the safety distance!
SICK recommends only mounting the V200 WS/V300 WS with
the protective field vertical (protective field parallel to the front
face of the hazardous area).
Ensure the necessary safety distance between the access
point and the hazardous point is met at all parts of the
protective field at an angle.
Note that different rules may apply to the calculation of the
safety distance for protective fields at an angle.
Your SICK-subsidiary will be pleased to assist you with the
implementation of special applications.

4.2.1 Safety distance according to EN 999 and EN 294
The safety distance as defined in EN 999 and EN 294 depends on:
stopping/run-down time of the machine or system
(The stopping/run-down time is shown in the machine documentation or must be
determined by taking a measurement.)
response time of the entire protective device (V200 WS/V300 WS: 20 ms)
reach or approach speed
other parameters that are stipulated by the standard depending on the application
How to calculate the safety distance S according to EN 999 and EN 294:
The following calculation shows an example calculation of the safety distance. Depending
on the application and the ambient conditions, a different calculation may be necessary.
First, calculate S using the following formula:
S = 2000 × T + 48 [mm]
Where …
T = Stopping/run-down time of the machine
+response time of the protective device after light path interruption [s]
S = Safety distance [mm]
The reach/approach speed is already included in the formula.
If the result S is 500 mm, then use the determined value as the safety distance.
If the result S is > 500 mm, then recalculate S as follows:
S = 1600 × T + 48 [mm]
If the new value S is > 500 mm, then use the newly determined value as the minimum
safety distance.
If the new value S is 500 mm, then use 500 mm as the minimum safety distance.
Example:
Stopping/run-down time of the machine = 290 ms
Response time after light path interruption = 20 ms
T = 290 ms + 20 ms = 310 ms = 0.31 s
S = 2000 × 0.31 + 48 = 668 mm
S > 500 mm, therefore:
S = 1600 × 0.31 + 48 = 544 mm

4.2.2 Safety distance if OSHA and ANSI are applicable
Under the authority of OSHA and ANSI the safety distance as specified by ANSI
B11.19@1990 E.4.2.3.3.5 and Code of Federal Regulations, Volume 29,
Part 1910.217 … (h) (9) (v) depends on:
stopping/run-down time of the machine or system
(The stopping/run-down time is shown in the machine documentation or must be
determined by taking a measurement.)
response time of the entire protective device (V200 WS/V300 WS: 20 ms)
reach or approach speed
other parameters that are stipulated by the standard depending on the application
How to calculate the safety distance Dsaccording to ANSI B11.19D1990 E.4.2.3.3.5
and Code of Federal Regulations, Volume 29, Part 1910.217 … (h) (9) (v):
The following calculation shows an example calculation of the safety distance. Depending
on the application and the ambient conditions, a different calculation may be necessary.
Calculate Dsusing the following formula:
Ds=H
s×(Ts+ Tc+ Tr+ Tbm) + Dpf
Where …
Ds= The minimum distance in inches (or millimetres) between the hazardous point
and the protective device.
Hs= A parameter in inches/second or millimetres/second, derived from data on
approach speeds of the body or parts of the body. Often 63 inches/second
(1600 mm/second) is used for Hs.
Ts= Stopping/run down time of the machine tool measured at the final control
element
Tc= Stopping/run-down time of the control system
Tr= Response time of the entire protective device after light path interruption
(V200 WS/V300 WS: 20 ms)
Tbm = Additional response time allowed for brake monitor to compensate for wear
Any additional response times must be accounted for in this calculation.
Dpf = An additional distance added to the overall safety distance required. This value is
based on intrusion toward the hazardous point prior to actuation of the electro-
sensitive protective equipment (ESPE). Values range from 0.25 inches to
48 inches (6 to 1220 millimetres) or more depending on application.
Example:
For vertical protection with an opto-electronic protective device with an effective
resolution finer than 2.5 inches (64 millimetres), Dpf can be determined
approximately using the following formula:
Dpf (inches)= 3.4 × (Effective resolution – 0.276), but not less than 0.
