3 Safety
3.1 Intended use
The operating mode selector switch is suitable for machines that can be operated in mul-
tiple operating modes with different safety functions and/or work procedures. It enables you
to switch between defined operating modes, such as:
}Set-up mode
}Manual mode
}Automatic mode
}Service
The operating mode selector switch meets the following safety requirements:
}Interlock to protect against unauthorised switching
To switch to an operating mode with the (selection) pushbutton, contact with a transpon-
der key is required.
}Access permissions are restricted to certain groups
A transponder key with the relevant permission is required in order to switch to a certain
operating mode.
}Prevents unintentional switching
The switch to a different operating mode is only recognised once the corresponding (se-
lection) pushbutton has been operated for a defined period ("deliberate operator action").
Multiple operation of (selection) pushbuttons is detected.
}Safe "1oon" circuit of the operating mode outputs
The operating mode selector switch only ever leads to one operating mode output "1" sig-
nal.
When restarting, the device is in OM1 or in the last selected operating mode, depending on
the device configuration.
Depending on the application area and its respective regulations, the device can be used
up to SILCL2 (ENIEC62061) and up to PLd (ENISO13849-1), if the operating modes
are evaluated by a safety controller with safe "1oon" evaluation.
NOTICE
Faulty operation of PITmode can lead to hazardous situations. Switching to
an operating mode must not initiate a hazardous movement, nor can it can-
cel an existing control command.

A competent person is a qualified and knowledgeable person who, because of their train-
ing, experience and current professional activity, has the specialist knowledge required. To
be able to inspect, assess and operate devices, systems and machines, the person has to
be informed of the state of the art and the applicable national, European and international
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.
3.2.2 Warranty and liability
All claims to warranty and liability will be rendered invalid if
}The product was used contrary to the purpose for which it is intended,
}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.).
3.2.3 Disposal

4 Function description
The operating mode selector switch enables you to switch between 5 different operating
modes (operating modes OM1 ... OM4 and special operating mode OM5 (Service)).
For OM1 ... OM4, one button each is available. For the special operating mode (Service),
button OM1 must be operated for a certain period (see Monitoring of operating
time [ 56]). Each pushbutton is assigned a monitored semiconductor output (see Oper-
ating mode interface [ 20]). Operating the button changes the semiconductor output
from a "0" signal to a "1" signal. The operating mode selector switch guarantees that only
one of the semiconductor outputs has a "1" signal at any one time.
INFORMATION
OM storage of operating mode
When configured with OM storage (see Configuration of
functions [ 16]), after a restart the unit will start with the last selected
operating mode.
If OM storage is not configured, the unit always starts with OM1. For this
reason you should make sure that OM1 represents the safest operating
mode.

4.1 Configuration of functions
The operating mode selector switch has a DIP switch, which you can use to set the re-
quired communication mode for downloading the Key ID number and the unit's behaviour
}after the transponder key is removed and
}after the voltage reset
.
The communication modes have different functions. These functions are described in the
following subsections:
}Transmitter-controlled communication mode [ 31]
}Handshake-controlled communication mode [ 32]
}Advanced communication mode [ 33]

Function description
Operating Manual PIT m3.2p
1003176-EN-09 | 17
NOTICE
It is essential to note:
– The configuration may only be performed by a competent person.
– The configuration must be performed when the supply voltage is
switched off.
– The configuration is adopted as the device is started up, provided the
switch setting is valid. If not, the device switches to a "Device error"
fault condition.
– During operation, the DIP switch setting is monitored for any change.
If the switch setting is changed during operation, the device switches
to a "Device error" fault condition, remedy: Delete error [ 58].
– The communication mode changes when you change the DIP switch
setting from Pos. [1]-[4] to Pos. [5]-[8]. In this case you automatically
switch to advanced communication mode.

not a safety-related function. Switching of the operating mode has to be val-
idated in accordance with the requirements.

4.2 Operating mode interface
The operating mode interface consists of the monitored outputs SOM1 … SOM5 (see Block
diagram [ 14]). "SOM" stands for "Safe Operating Mode". The outputs are assigned to
buttons, which can be used to select an operating mode if they have the relevant authorisa-
tion (transponder key):
Pushbutton Output Operating mode
1 SOM1 OM1 The operating mode OM1/OM5 is selected
based on the operating time of button 1 (see
Monitoring of operating time [ 56])
SOM5 OM5
2 SOM2 OM2
3 SOM3 OM3
4 SOM4 OM4
4.2.1 Switch behaviour after a transponder key is removed
If the transponder key is removed after changing to a different operating mode, it is possible
to configure the subsequent switch behaviour of SOM1 … SOM5. A DIP switch is available
for this purpose (see Control elements [ 9]).
The individual switch settings and the resulting switch behaviour are described in the
chapter entitled Configuration of functions [ 16].
4.2.2 Control program requirements
In order to achieve SIL CL 2 (EN IEC 62061)/PL d (EN ISO 13849-1) in an application, the
evaluation must be carried out by a safety-related function block. The safety-related func-
tion block must meet the following requirements:
}The function block must enable safe "1oon" evaluation of the output signals at SOM1 ...
SOM5.
}If two or more operating modes are present at the same time, this must be detected as an
error.
INFORMATION
The function block must bridge the t1 switchover delay (see Switchover
delay t1 [ 57]).
If a PNOZmulti (e.g. PNOZ m1p) is used as the safety controller in conjunc-
tion with an "operating mode selector switch" function element, then this re-
quirement is met automatically.
