Hinge Switches –

NOTE: Refer to the installation instructions
Two safety switches must be used for each
interlock guard to achieve control reliability
or Safety Category  (per ISO 1389-1,
EN 9-1) of a machine stop circuit. Use of
only one safety switch per interlock guard is
not recommended.
In addition, normally-closed safety contacts
from each of the two safety switches should
be connected to the two separate inputs of a
2-channel safety module or safety interface, as
illustrated in Figure 4. This is required to provide
monitoring for safety switch contact failure,
and to provide the necessary reset routine, as
required by IEC 60204-1 and NFPA 79 machine
safety standards.
Monitoring multiple guards with a series
connection of multiple safety interlock
switches is not a Safety Category 
Application (per ISO 1389-1, EN 9-1).
A single failure may be masked or not
detected at all. When such a configuration
is used, procedures must be performed
regularly to verify proper operation of each
switch.

As illustrated in Figure 4, a normally-closed safety contact (i.e., a safety contact that is closed
when the actuator is engaged) from each of two safety switches per interlock guard must
connect to a 2-channel safety module or safety interface in order to achieve a control reliable
interface to the master stop control elements of a machine. Examples of appropriate safety
modules include 2-channel emergency stop (E-stop) safety modules and gate monitor safety
modules.
Two functions of the safety module or safety interface are:
1. To provide a means of monitoring the contacts of both safety switches for contact failure,
2. To provide a reset routine after closing the guard and returning the safety switch contacts
Use only the positively driven, normally closed safety contact (between pins 11 and 12 or 21
and 22) from each switch for connection to the safety module. A typical use for the non-safety
auxiliary contact (between pins 33 and 34) is to communicate with a process controller. Refer
to the installation instructions provided with the safety modules for more information regarding
the interface of the safety module to the machine stop control elements.
Safety switches should be checked at each shift change or machine setup by a designated
person (see below) for:
• Breakage of the switch body.
• Confirmation that the safety switch is not being used as an end stop .
• Verification that it is not possible to reach any hazard point through an opened guard
• Verification that the hinge swings freely throughout its total operating range.
• Loosening of mounting hardware.
• Signs of deterioration or damage.
• Signs of tampering or defeat to the switch or to the wiring interface to the machine.
A designated person is identified in writing by the employer as being appropriately trained to
perform a specified checkout procedure.
Do not attempt any repairs to the switch. It contains no field-replaceable components.
Return the switch to the factory for warranty repair or replacement.
If it becomes necessary to return a switch to the factory, contact Banner at the number or
address listed on the back cover. An applications engineer will attempt to troubleshoot the
problem or will issue an RMA (Return Merchandise Authorization) number for your paperwork,
and give you the proper shipping address.
Pack the switch carefully. Damage which occurs in shipping is not covered by warranty.
and to prevent the machine from restarting if either switch fails; and
to their closed position. This prevents the controlled machinery from restarting by simply
closing the guard. This necessary reset function is required by ANSI B11 and NFPA 79
machine safety standards.
