4-1
OSSD
An OSSD output is a safety output for the safety-related part of a machine
control system.
OSSD 1/2 is a pair of safety outputs that are redundant.
The GS (Non-contact) generates self-diagnosis signals on its internal control
circuit to perform diagnostics on the OSSD. These signals periodically force the
OSSD into a temporary OFF-state when the OSSD is in the ON-state.
If the internal control circuit receives a feed-back signal (OFF-signal) based on
the self-diagnosis, the GS (Non-contact) determines that its OSSD is operating
normally. If the OFF-signal is not returned to the internal control circuit, the GS
(Non-contact) determines that there is a problem with the OSSD or wiring and
goes to an error state.
OSSD operation
The OSSDs go to OFF state:
•
During startup, in the error state, when switching the coding level
When all the conditions shown below are met during normal operation, the
OSSDs go to ON state. (*1)
•
The sensor has detected an actuator.
•
Safety inputs are ON.
*1: The OSSDs go to OFF state in the interlock reset ready state.

DANGER
•
For the wiring to a safety-related machine control system,
the output of both OSSD 1 and OSSD 2 must be used by the
safety-related machine control system in order to create a
safety system.
•
If only one OSSD output is used to construct the machine’s
control system, an OSSD malfunction will make it
impossible to stop the machine, which may lead to
extremely dangerous situations including serious injury to
or death of the machine’s user.
•
When using a PNP sensor, do not cause a short-circuit
between the OSSD and +24V. Otherwise, the OSSDs will
stay in the ON-state and it will cause a dangerous situation.
•
When using a PNP sensor, be sure to connect the load
between the OSSD and 0 V. Connecting this between the
OSSD and +24 V by mistake will invert the OSSD operation
from its normal behavior, which is extremely dangerous.
•
When using an NPN sensor, do not cause a short-circuit
between the OSSDs and 0V. Otherwise, the OSSDs stay in
the ON-state and it will cause a dangerous situation.
•
When using an NPN sensor, be sure to connect the load
between the OSSD and +24 V. Connecting this between the
OSSD and 0 V by mistake will invert the OSSD operation
from its normal behavior, which is extremely dangerous.
•
To prevent malfunctions caused by ground faults on the
OSSD output wire, perform wiring in a manner such that the
requirements specified in paragraph 9.4.3 of IEC 60204-1
are met.

Safety Input
This function controls the OSSDs of the GS (Non-contact) with input signals
from sensors or similar devices connected to the safety inputs.
Safety input 1 and safety input 2 form a safety input pair. If safety input 1 or
safety input 2 turns OFF, the OSSDs turn OFF.
Multiple GS units can be connected and used in an expanded system (with a
cascade connection) by connecting the OSSDs of a different GS (Non-
contact) or GS (Lock) to the safety inputs. The system can be expanded to
include up to thirty units in the case of the GS (Non-contact).
Point
The simple function type has no safety input.
Reference
•
Wire the safety inputs as shown below when they are not in use.
PNP type: Short circuit to 24 V.
NPN type: Short circuit to 0 V.
•
If safety input 1 and safety input 2 are mismatched for 3
seconds or more a Safety Input Error will occur.
Emergency stop switch/button wiring
Wiring an emergency stop switch/button to the safety inputs makes it
possible to perform an emergency stop on the machine by pressing the
emergency stop switch/button.
4-3
Interlock Function
Interlock is a function that prevents the OSSDs from automatically going into
the ON-state from the OFF-state. This prevents the unintended start-up and/or
the unintended restart of the machine if the interlock is applied to the GS
(Non-contact). It is necessary to perform the reset operation in order for the
GS (Non-contact) to go back to normal operation from the interlock condition.
Point
The interlock function cannot be set on the simple function
type and standard type. The interlock function is fixed to
Automatic.
On the advanced function type, the interlock function setting can be selected
from two types: Automatic and Manual.
Automatic and Manual indicate the following operations.
Automatic:
The OSSDs immediately switches to the ON state when the conditions for
doing so-such as the door closed-are met.
Manual:
Even if the conditions for switching the OSSDs to the ON state are met, the
OSSDs maintain the OFF state (interlock state).
<Terminating the interlock state>
To set the OSSDs to the ON state and to start the machine, close the door to
which the GS (Non-contact) has been installed and perform the reset
operation after the preparations for starting the machine are complete. This
sets the OSSDs to the ON state and terminates the interlock state.
Interlock function settings
Use the wiring to configure the settings. The wiring method varies depending
on whether the
“4-4 EDM Function” (page 6) is used.
4-4
EDM Function
The GS (Non-contact) can monitor the state of external devices, such as a
safety relay or contactors that are connected to the OSSDs, in order to detect
the failure of the external device. This monitoring function is called the EDM
function.
EDM function settings
Use the wiring to configure the settings. The wiring varies depending on
whether the interlock function is used. For details, see
4-5
AUX Output
This is an informational output used to check the operating status of the GS

Exercise caution to prevent the reset/EDM input from
forming a short circuit with other inputs or outputs.
DANGER
The AUX outputs cannot be used as the safety outputs to a
safety-related control system.
Coding level: Low
(multi operation)
Any actuator is detected when it enters the range of
the operating distance from the sensor. (Initial setting)
Coding level: High
(unique operation)
Only the specific actuator that the sensor has been
taught to detect is detected when it enters the range of
the operating distance from the sensor. The sensor
does not respond if an actuator other than the actuator
that it has been taught to detect is within the range of
the operating distance.

Inspection and Maintenance
Inspect the safety function of the GS (Non-contact) on the basis of the results
of a risk assessment of the target machine. It is strongly recommended that,
at minimum, the following items and periods be met.
• Initial inspection
Items
The sensor and actuator are installed on the basis of the installation
conditions, installation methods, and wiring specifications specified in this
manual.
The safety functions being used (“4-1 OSSD” (page 5), “4-2 Safety Input”
(page 6), “4-3 Interlock Function” (page 6), or “4-4 EDM Function” (page
6)) operate as intended.
• Periodic inspection
Periods
SIL3/PLe: Once/month or more, SIL2/PLd: Once/year or more (ISO 14119)
Items
If an emergency stop switch is connected to the safety input, the safety
function acts correctly when the emergency stop switch is pressed.
There are no changes in the mounting conditions of the sensor and
actuator or in the doors, etc. to which these devices are installed.
The door, etc. is not deformed.
There are no changes to the installation status that will affect the results of
the risk assessment carried out at the start of the installation.
The mounting screws and seals (in the case that seals have been applied
to the manual release) have been applied correctly.
No excessive damage or dirt is present.
Especially in the following cases, check the same details as the initial
inspection.
