For further details of the test condition setting procedures, refer to page 38.
● Operation timing is as follows:
・Set the DLY timer to delay pressure applying timing (①).
・Error 5 and 6 functions are only controllable via REMOTE connector.

● Connect + line to ①, and －line to ②. For a 3-wire cylinder, connect power line to ③.
● Choose limit switches that fulfill the following specifications:
・ Load (power) voltage: DC12V
・ Power Consumption (for 3-wire switch): 50mA or less for the total of the load connected to COM +
・ Load current: 5mA
・ Voltage Drop: Less than 3V
・ Leakage Current: Less than 1mA
● Choose solenoid valves for cylinder controls that fulfill the specifications indicated below:
・Driving Voltage : FL-2□□□-0：AC100V 50/60HZ
FL-2□□□-2：To accord with external valve power source specs.
・ Power Consumption : Less than 100VA
・ Preset the Air Leak Tester testing condition to:
● Set to condition setting status.
