[Design Precautions]
WARNING
● A safety relay module turns OFF all outputs by safety input or a failure of external power supply.
Create an external circuit to securely stop the power of hazard by turning OFF the outputs.
Incorrect configuration may result in an accident.
● When overcurrent due to such as load short-circuit or load current exceeding the rating flows for a
long time, it may cause smoke or fire. To prevent this, create external safety circuit such as a fuse.
● Create short-circuit current protection for a safety relay and a protection circuit such as a fuse and
breaker, outside a safety relay module.
● To inhibit a restart without manual operation after safety function of the safety relay module was
performed and outputs were turned OFF, create reset start-up circuit using such as a reset switch
outside the safety relay module.
● The safety relay module may consume excessive current due to a failure. If this occurs, the DC
power supply connected to the safety power supply part (+24V (SAFETY) and 24G (SAFETY)
terminals) of the module detects an overcurrent and may shut off the output. To the DC power supply
connected to the safety relay module, connect only the equipment and the devices that will not affect
the system even if they are simultaneously stopped due to power-off.
● Use an extension module whose input type is the same as that of the main module. The modules of
different input types (input P and N types) cannot be connected.

OVERVIEW
1.2 About Safety Relay Module
The safety relay module achieves basic safety functions for emergency stop only by
wiring, without programming.
It is safety check type module whose output does not turn ON until all conditions of the
safety input (normally closed contact), off check input (normally closed contact), and startup switch (normally open contact) are met.
Using the module helps to reduce the man-hour taken for configuring a safety check
system.

OVERVIEW
(5) Small-scale safety control
The safety relay module is suited for small-scale safety control whose number of I/O
points is around 10.
(a) Programming is unnecessary.
Safety circuits can be easily created only by wiring, without programming and
settings.
Since an inspection on programming by safety certification organization is
unnecessary, the man-hour taken for obtaining the safety approval can be
omitted.
(b) Extension of safety circuit with extension module
By connecting extension safety relay modules, maximum 4 points of safety input
and maximum 4 points of safety output can be controlled.
(c) Safety control can be performed by itself.
Since a communication circuit for Q series programmable controller and CC-Link
is separated from a circuit for achieving the safety function, the safety relay
module can perform safety control by itself, independent of a failure of the Q
series programmable controller or CC-Link communication status.
(6) Fail safe
Fail safe can be achieved by inhibiting the safety relay module from starting when an
error occurs in safety input, start-up input, and/or internal circuit of the safety relay
module.
(7) Improvement of efficiency in wiring work
Using spring clamp terminal block allows to skip screw tightening work and to reduce
wiring work significantly.
(8) Connector insertion check
Using terminal block cover for connector insertion check prevents poor connection. If
the terminal block is not inserted securely, the terminal block cover does not close.

2.4 Precautions for Use
Users must prove that their entire safety system complies with the safety standards and
the Machinery Directive. The third-party certification organization will validate the safety of
product for the entire safety system, including a safety relay module and safety
components.
To establish a safety system, calculate the target performance level (PL) for each safety
application (safety function) based on the MTTFd and DCavg values of the safety relay
module and connected safety components. The calculation equation is shown in
ISO13849-1:2006.
MTTFd and DCavg of the safety relay module are shown in following.

4.1 Dual Input Function
This function doubles safety inputs to prevent damage of the safety functions due to a
single failure.
The doubled safety inputs operate after making sure that the internal module, external
devices, and wiring are normal by the start-up/off check function, Briefly, if a module,
external devices or wiring has a failure, the module does not start.
After module start-up, if one safety input does not turn OFF due to a failure, the output is
cut off by turn-OFF of the other safety input.

• Wire the start-up/off check input so that the external wiring length can be
50m (164.04 feet) or less.
• The timing of safety input and start-up/off check are inconstant.
Therefore, control using this timing cannot be made.

4.3 Start-up Method Selection Function
This function allows to select the start-up method with the start-up mode setting switch.
The start-up method has auto mode and manual mode.
(1) Auto mode
This mode starts automatically after safety input and off check are all met.
Set the start-up mode setting switch to "A" side.
Use this mode when connecting such as door switch.
(2) Manual mode
This mode starts by pressing the start-up switch when safety input and external
device connected to the start-up/off check terminal are all met.
The mode starts after the start-up input turns from ON to OFF to prevent a malfunction
due to contact welding of the start-up switch.
Set the start-up mode setting switch to "M" side.
Use this mode when connecting such as operation preparation switch.

• Short-circuit between the start-up input XS0 and XS1 during the auto
mode.
Doing so may cause a malfunction or failure of the module.
• According to the standard, the system cannot start at the auto mode for
operation preparation or when using the light curtain.
In this case, connect the start-up switch or recovery reset switch and use
it in the manual mode.
• When using the start-up switch during the manual mode, always use the
momentary type of NO (normal open).
Connect the normally closed contact of forcibly guided type to off check
input.
If using other than mentioned above, it may cause a malfunction or failure
of the module.
• Do not change the start-up mode setting switch settings after powering
ON.
4.4 Safety Output Function
This function prevents incorrect output due to a single failure by doubling safety relay
outputs internally.
The output can be stopped even if the one contact fails due to welding.
Moreover, once a contact fails due to welding, the system does not start after that;
therefore, the safety is not damaged.

Figure 4.5 Partial shutdown with extension module
The following shows an operation example when the safety relay module system in Figure
4.5 is configured.
• If SW0, safety input switch of the main module, is pressed, the whole outputs
(M0, M1, M2, M3) are shut off.
• If SW1, safety input switch of the extension module on station number 1, is
pressed, only output of the extension module (M1) is shut off.
• By shorting the safety input of the extension module on station number 3, the
safety input is synchronized with the safety output of the main module and is
driven/shut off.
The safety output of the extension module can be synchronized only with main
module: therefore; it cannot be synchronized with another extension module.

2) Precautions for selecting power supply
Power of a light curtain is supplied from power supply connected between
+24V(SAFETY) and 24G(SAFETY) of the main module via the COM terminal
of the extension module. If the current or voltage supplied from the COM
terminal is insufficient, operation of the light curtain cannot be guaranteed.
Select the power supply device which meets the following conditions.
Power supply output voltage : 24 10% [V]
Power supply output current : Main module current consumption (85[mA]) +

[Calculation example]
A calculation example for the system with three extension modules and two
light curtains is shown below.
In the example, current consumption of each light curtain is assumed as
follows.

(c) Precautions for connecting a light curtain
When connecting a light curtain referring to the connection diagram shown in
Figure 5.15, pay attention to the following.
1) Light curtains cannot be connected to the main module and the extension
*1
module respectively at the same. Only a switch
can be connected as safety input of the main module.
2) Up to three extension modules can be connected to one main module. In this
case, however, up to two extension modules are available for connecting a
light curtain (one light curtain per module).
For the third extension module, only a switch
be connected.
3) Power supply of a light curtain is cut off by turning on (opening the contact of)
the switch which is connected to the input X0 and X1 of the main module.
Check the time required for the light curtain to restart in the specification and
provide an interlock until the restart of the light curtain is completed.
4) When connecting a switch to the X0 and X1 terminals of the main module, wire
the cables so that the cable length becomes within 10m for both between the
X0 and COM terminals and between the X1 and COM terminals.
* 1: Switch means a device whose condition between the COM terminal and X0 or X1 terminal is
short-circuited when the switch is off (the contact is closed) and that has no load to develop
voltage drop in the closed circuit.

5.4.6 Precautions for wiring power supply
When wiring to the power supply of safety relay module, take care of the following points.
• Cable length of the module power supply must be within 10m (32.81 feet) or less.
• The power supply to be connected to the safety relay module must meet the
following conditions.
1) The switching power supply complies with the EMC Directive, EN50178,
EN60950-1 standard, and NEC CLASS2.
2) SELV (Safety Extra Low Voltage): Reinforced insulation from hazardous
potential area (48V or more) is provided.
3) The power supply complies with the LVD Directive.
4) The output voltage specification value is from 20.4 to 26.4VDC (ripple ratio
within 5%).
• Use respective power supply for the module power supply and the safety power
supply in order to obtain safety approval.
• Operating voltage range may differ for each module. Be careful with that when
sharing the power supply with other Q/QS series modules.
• The safety relay module may consume excessive current due to a failure. If this
occurs, the DC power supply connected to the safety power supply part (+24V
(SAFETY) and 24G (SAFETY) terminals) of the module detects an overcurrent
and may shut off the output.
To the DC power supply connected to the safety relay module, connect only the
equipment and the devices that will not affect the system even if they are
simultaneously stopped due to power-off.

5.4.7 Connecting extension modules
(1) Adding the safety part
• Use an extension module whose input type is the same as that of the main
module. The modules having different input types (input P and N types) cannot
be connected.
• For addition of the safety part, use a safety circuit part extension cable shown on
Section 3.6.
If using another cable, the operation is not guaranteed.
• Connect safety part terminating connector attached to the main module to “OUT”
connector on the extension module on the last stage.
If unconnected, the module does not operate.
(2) Adding the monitor part
Use shielded cable to add the monitor part and ground the shield.
Not doing so may cause a malfunction due to noise.

TROUBLESHOOTING
CHAPTER 6 TROUBLESHOOTING
This chapter explains description, cause investigation, and corrective action of an error
when using the safety relay module.
To increase system reliability, starting the system early in the case of a failure is important
as well as using the highly-reliable devices.
The following is the basic three points that should be noted when performing
troubleshooting to find a failure cause, take corrective action against it, and start the
system early.
(1) Visual check
Check the following points.
1) Machine status (stop status, operating status)
2) Status of safety relay module power supplies

OVERVIEW
SYSTEM
CONFIGURATION
3) External device status
4) Module mounting status
5) Wiring status (safety input line, power supply cable, CC-Link dedicated cable,
extension cable)
6) Indication status of various indicators (POW, PW, ERR., K0, K1, Z, X0, X1,
L RUN, SD, RD, L ERR.)
7) Setting status of various setting switches
After checking from 1) to 7), monitor PLC diagnostics, module operating status, or
program contents with GX Developer.
(2) Failure check
An failure is divided into two categories as shown below.
(a) Safety-related failure
1) Whether the safety input is ON
2) Whether the safety input does not change at start-up
3) Whether the external device connected to off check remains OFF until start-up
4) Whether K0 and K1 LEDs are both OFF before start-up

1) Switch the RUN/STOP/RESET switch on the programmable controller to
“STOP”.
2) Switch the RUN/STOP/RESET switch on the programmable controller to
“RESET”.
3) Power ON/OFF the monitor sides of the safety relay module and
