CAUTION
• When setting the SAFE mode, use the 100% setting for the stroke length. If the stroke length is
changed, the pressure may rise above the rated level.

SAFE mode
When the SAFE mode is enabled, the force of the pumped chemical liquid is controlled during a blocked operation to
prevent the pressure from rising.
It is recommended that the SAFE mode be set when using only the pressure of the anti-siphonal check valve or at
other times when the pump is used at a low pressure.
If the “P-03 Blocked operation” parameter is enabled when the SAFE mode is enabled, an alarm is displayed and out-
put at a pressure level that is lower than normal.
ECO mode
When the ECO mode is enabled, the power-on time is
automatically reduced in accordance with the variations
in the discharge pressure, and the power consumption
is reduced.
✽
When the ECO mode is enabled for the DCLPW
or CLPW , it becomes harder to vent the air so use
‘disabled’ as the ECO mode setting.
