   - Insulated ferrule: AWG24 to AWG16 (0.25 to 1.5 mm

2

)

   - Crimp height(H): 2.0 mm max.          Width(W): 2.7 mm max.          Conductor length: 8 to 10 mm
  When using the twin type ferrule, use equal-sized wires and preferred insulated ferrule.
  The twin type ferrule should not be above the adjoining release hole.

How to insert solid wire and insulated ferrule

The wire should be pushed into the terminal block straight. No need to use the driver.
After inserting, make sure wire is fastened on to terminal block.

How to release wire

Use the following minus drive to release wire from terminal block.  
And When releasing wire, the power source should be disconnected first.
1. Push the driver lightly into the taper of release hole.
2. Pull out the wire while the driver is pushed into release hole.
3. Pull out the driver.

Terminal block may be damaged.
1. Not push the driver into the release hole straight.
2. Not push the driver into the release hole by force of 30N and over.
3. Not tip or twist the driver pushed into release hole. 

Precautions for Correct wiring

Fault Detection

When G9SE detects a fault, LED indicators blink to show the information of the fault.

When PWR indicator blinks, check and take needed measures referring to the following table. And then 
apply supply voltage to G9SE.

PWR

1) Failures involving the wiring of
Safety input 1

1) Failures involving the wiring of
Safety input 2

1) Supply voltage outside the 
rated value.

Expected causes of 

the faults

Checking points and

measures to take

1) Check the wiring to T11 and T12.

When using stranded wire, insulated ferrule should be used. Use below insulated ferrule.
But do not use ferrule terminals if G9SE is used as UL Listing. Insert the strand or solid wire(CU only) directly 
into the holes on the terminal block.

Performance level and safety category 

(EN ISO13849-1)

In the conditions shown in '5.Examples of Application' , G9SE can be used for the corresponding safety 
categories up to 4 and performance level(PL) up to e per ISO13849-1.
This does NOT mean that G9SE can always be used for the required category under all the similar conditions 
and situations.
Conformity to the categories must be assessed as a whole system. 
When using G9SE for the safety categories, make sure the conformity of the whole system. 
  1) Input the signals to both of the Safety inputs (T12 and T22)
  2) Input a signal to the Safety inputs (T11-T12 and T21-T22) through switches with Direct Opening 
      Mechanism. When using limit switches, at least one of them must have Direct Opening Mechanism.

  And wiring must be done in a way that a short circuit between the wires of Safety input can be     
  prevented.

  3) When connecting a Safety sensor with G9SE, use a TYPE 4 safety sensor.
  4) Be sure to connect the negative terminal  of DC power supply to ground.
  5) Use two Safety outputs (e.g. 13-14 and 23-24) to construct the system.
  6) In order to ensure sufficient failure detection, it is mandatory to use G9SE only together with 
      contactors or relays with forcibly guided contacts.
  7) Input the signal through NC contacts of the contactors to Feedback/Reset input (T31-T32 for manual   
      reset or T31-T33 for auto reset). (Refer to '5.Examples of Application'.)

To set Safety outputs in ON state, HIGH 
state signals must be input to both of 
Safety input 1 and Safety input 2.
Otherwise Safety outputs cannot be in 
ON state.

To set Safety outputs in ON state, ON 
state signal must be input to T33.
Otherwise Safety outputs cannot be in 
ON state. (See Note1)

To set Safety outputs in ON state, the 
signal input to T32 must change from 
OFF state to ON state, and then to OFF 
state. Otherwise Safety outputs cannot 
be in ON state.

Turns ON/OFF according to the state of 
safety inputs, Feedback/Reset inputs.
During off-delay state, safety outputs 
are not able to turn ON.

Off-delayed safety outputs.
(See Note2)
Off-delay time is set by off-delay preset 
switch.
When the delay time is set to zero, 
these outputs can be used  as 
instantaneous outputs.

Outputs a signal of the same logic as

Connecting Safety Sensors and G9SE

P

s Max.

In many case, Safety Sensor outputs include the off-shot pulse for its self test.
The following condition of test pulse is applicable as safety inputs for G9SE.

  

- Off-shot pulse width of the sensor, during the ON-state : 640 μs 

(1) Construct the safety system taking into account that in the Auto reset mode Safety outputs turn ON 
      automatically when Safety inputs 1 and 2 turn ON.
(2) When the inputs of G9SE-221-T

Ƒ

 are restored during off-delay time, G9SE-221-T

Ƒ

 will operate

      as below. Depending on the reset mode.
        - Auto reset mode: Outputs turn off after off-delay time, then immediately turns on.
        - Manual reset mode: Outputs turn off after off-delay time, then turn on when reset input is given.
