4)   Digital input signal 1 is for Run/Stop signal (Signal type: Alternate), digital input signal   

2 is for external switch signal (Signal type: Alternate).Refer to Chapter 2.3.3 for details of   
the external switch.

 

 
 
 
 
 

 

 
 
 
 
 
 
 

(1)  The product starts operation when the Run/Stop signal from the user is turned ON.

 

(2)  It reads the signal of the external switch signal (N.O type) after the time which has 

been set for the [Delay] time.

 

(3)  When the external switch signal (N.O. type) has been turned off for the time set for 

 

[Off Detection] time, it is recognized as OFF.

 

(4)  Alarm  [AL31:Contact  input  2  signal  detection]  is generated. The operation of the 

product stops. 

(5)  The  product  stops  operation  when  the  Run/Stop  signal  is  turned  OFF  during 

operation. Afterwards, the alarm is not generated even if the external switch signal 
is turned OFF.

 

 
 

2.3.3 

External switch signal 

The product has two contact inputs available to detect the contact input signal.   
This allows reading and monitoring the contact signal from an external switch.

 

When inputting an external switch signal to the contact input, select “External   
Switch” (external switch signal) for the type of contact input signal.(Refer to   
“2.3.1

 

Setting of contact input signal type and form

)

 

If an input from an external switch is detected, it can be generated as an   
alarm.

Options to select “continuous monitoring” or “monitoring during   

operation” are available. Also, the detection start time after the start of   
operation and the detection end time can be set. 

 

 

If the signal of “contact input 1” is detected: the alarm “AL30: Detection 

of contact input 1 signa

l” is activated.

 

 

If the signal 

of “contact input 2” is detected: the alarm “AL31: Detection 

of contact input 2 signal” is activated.

 

 

“Delay” time: sets the start time to detect the contact input signal after 
the start of operation. 

 

“Off detect” time: sets the time between the detection of the contact input 
OFF signal and the activation of the alarm.
