6-6 Adjustment Procedure When Using the Device with the Booster
Relay Attached
When using the device with the booster relay attached, perform adjustment according to the following
procedure.
Assemble the device and
booster relay onto the control valve.
Adjust the booster
relay sensitivity.
Perform auto setup.
Manually specify
dynamic characteristics.
Re-adjust the booster relay sensitivity.
Status during friction
level measurement
Dynamic
characteristics test
Change the dynamic
characteristics again.

Properly connect the pneumatic piping to the connection
ports on the device and the booster relay.

- Permanent hunting
End adjustment.
Good
Normal
Hunting occurs.
Adjust the sensitivity by operating the sensitivity adjustment
throttle on the booster relay.
* Rotate the sensitivity adjustment throttle by one and a half
revolutions from the highest sensitivity (sensitivity
adjustment throttle fully closed) to lower the sensitivity of
booster before using a general IL100 model.
For other booster relays, lower the sensitivity before use.
Lower the input signal and rotate
the booster sensitivity adjustment
throttle by about 1/4 to 1/2
revolution to further lower the
sensitivity.
Lower the input signal and interrupt
auto setup. Add the input signal again
and use the communication tool to:
- Change the actuator size *1
- Change the friction level *2
- Change control parameters *3
Perform the five-point
check to check the
dynamic characteristics.
Use the communication tool to:
- Change the actuator size *1
- Change the friction level *2
- Change dynamic
characteristics data *3
- Large amount of
overshoot (undershoot)
- Stabilization takes time.
*1 : Toward smaller numbers (Param 6 to 5 to 4 ...)
*2 : From Light to Medium to Heavy
*3 : Reduction in P or I, or increase in D, etc.
