increase the cycle time, change the cycle rate to

 

 

 

 

“SL” in the configuration menu. It is not possible to

 

 

 

 

shorten the cycle time. If an acceptable cycle rate

 

 

 

 

is not achieved as received or by changing the

 

 

 

 

cycle rate. Contact a local service person for
