USER'S GUIDE
<G9SX-GS @ >
( 1 ) Be sure to correctly connect safety input devices to safety
input A and safety input B to ensure proper operation of the
safety functions.
( 2 ) When setting the Switching Function, be sure to consider
safety control requirements, safety level and safety
category of the entire system.
( 3 ) A qualified personnel who has a thorough understanding of
the installed machine must switch the mode selector input.
For example, a Switching Unit with Key must be used for
the mode selector, and the key must be managed and used
in such a way that the machine cannot be operated by
unauthorized persons.
<G9SX-EX @ >
( 1 ) The durability of relays depend greatly on the switching
condition. Confirm the actual conditions of operation in
which the relay will be used in order to make sure of the
permissible number of switching operations.

Precautions for Correct Use
<Precautions for All G9SX Models>
( 1 ) Handle with care
Do not drop G9SX to the ground or expose to excessive
vibration or mechanical shocks. G9SX may be damaged
and may not function properly.
( 2 ) Conditions of storage
Do not store in such conditions stated below.
1. In direct sunlight
2. At ambient temperatures out of the range of
−
10 to 55
°
C.
3. At relative humidity out of the range of 25% to 85% or
under such temperature change that causes
condensation.
4. In corrosive or combustible gases
5. With vibration or mechanical shocks out of the rated
values.
6. Under splashing of water, oil, chemicals
7. In the atmosphere containing dust, saline or metal
powder.
G9SX may be damaged and may not function properly.
( 3 ) Mounting
Mount G9SX to DIN track with attachments (PFP-M, not
incorporated to this product), not to drop off the track by
vibration or other force especially when the length of DIN
track is short compared to the widths of G9SX.
( 4 ) Following spacing around G9SX should be available to
apply rated current to outputs of G9SX and for enough
ventilation and wiring:
1. At least 25 mm beside side faces of the G9SX.
2. At least 50 mm above top face of G9SX and below
bottom face of G9SX.
( 5 ) Wiring
1. G9SX
•
Wire the G9SX as described below.
•
Strip no more than 7 mm of insulation from the end of
the wire.
•
It is recommended that stranded wire be covered with
insulated 0.25- to 2.5-mm
2 ferrules before connecting it.
2. G9SX- @ -RT (with Screw Terminals)
•
Tighten each screw to 0.5 to 0.6 N·m or the G9SX- @ -
RT may malfunction or generate heat.
3. Wiring for a Logical AND Connection
•
Use a 2-conductor cabtire cable or shielded cable to
wire a logical AND connection between Units.
( 6 ) Connecting Expansion Units (G9SX-EX @ - @ ):
(Only G9SX-AD @ /-ADA @ /-NSA @ /-GS @ )
1. Remove the termination connector from the G9SX, and
insert the connector of the Expansion Unit into the
G9SX to connect it.
2. Insert the termination connector into the last Expansion
Unit as viewed from the G9SX. When the G9SX is used
without any Expansion Units, do not remove the
termination connector from the G9SX.
3. Do not remove the termination connector while the
system is operating.
4. Before applying the power supply voltage, confirm that
the connecting sockets and plugs are locked.
5. Make sure that all connected Expansion Units are
supplied with power within 10 s after the power to the
G9SX is turned ON. Otherwise, the G9SX will detect a
power supply error for the Expansion Units.
( 7 ) Use cables with length less than 100m to connect to Safety
Inputs, Feed-back/Reset inputs, or between Logical AND
connection inputs and Logical AND connection outputs,
respectively.
( 8 ) Set the time duration of OFF-delay to an appropriate value
that does not cause the loss of safety function of system.
( 9 ) Logical AND connection between Units:
1. When using Logical AND connection inputs, set the
Logical AND connection preset switch to 'AND' position
for the units which the logical AND connection signal
are input to.
2. Connect Logical AND connection outputs appropriately
to Logical AND connection inputs of the relevant unit.
Verify the operation of G9SX before commissioning the
system.
3. When configuring the safety related system, be sure to
consider that the delay of response time caused by
logical AND connections do not degrade the safety
function of the system.
4. Use 2-conductor cabtire cable or shielded cable for
logical AND connections between Units.
(10) To determine the safety distance to hazards, take into
account the delay of safety outputs caused by the following
times:
1. Response time of safety inputs
2. Response time of logical AND connection input
(Also consider the precaution in "Note" below)
3. Preset OFF-delay time
4. Accuracy of OFF-delay time
Note: When connecting multiple Units with logical AND
connections, the operating time and response time
after logical AND connection inputs will be the sum
of the operating times and response times of the
Units that are connected in series by logical AND
connections.
(11) Start entire system after more than 5s have passed since
applying supply voltage to all G9SXs in the system.
