Operation
Discharge-volume setting
Setting the discharge capacity using the stroke length
•
The stroke length of the diaphragm can be adjusted by turning the stroke-length adjustment
dial located at the back of the solenoid box.
✽
When the dial is moved while the pump is stopped, the dial setting may shift during pump
operation. If this happens, adjust the dial again.
Adjustable range of stroke length: 50 to 100%
This product can be controlled using the three methods described below.
(1) Setting the discharge capacity by manual operation
(2) Setting the discharge capacity using the stroke length
(3) Controlling operation using signal input
Methods (1) and (2) are described here.
✽
For method (3), refer to the control functions on page 28.
Setting the discharge capacity by manual operation
■
Stroke number setting mode
The discharge capacity can be set by increasing or reducing the number of strokes.
In the manual mode, the number of strokes can be changed using the [
] and [ ] keys on the control panel.
After changing the setting, press the SET key to enter the change.
Setting range: 1 ~ 300strokes/min
Example of setting: Changing the number of strokes per minute from 300 to 150 for the PW-30
Discharge capacity: 30 ml/min. Number of strokes changed to 150 Discharge capacity: 15ml/min
■
Discharge capacity setting mode (PW, DCLPW and CLPW only)
When the control type is PW, the discharge capacity can be set directly.
Proceed with calibration before use in order to ensure that the precise discharge capacity is obtained.
For details on calibration, refer to Setting flow at the end of this manual.
Setting range: 0.1 to (maximum discharge capacity of model) ml/min.
IMPORTANT
•
The description in the section on “Discharge-volume setting” assumes that the stroke length is set to
100%. Therefore, when the stroke length has been changed, reduce the maximum discharge volume and
discharge volume per stroke at the same ratio.
•
Mainly use the stroke speed to adjust the discharge volume, and use the stroke length in an auxiliary
capacity (for fine adjustments).
• Do not set the stroke length to below 50%.
!
CAUTION
• Operate with the stroke length set to 100% when the SAFE mode, ECO mode, or ALARM functions are
to be enabled.
