Power Failure Processing
When a power failure occurs while the pump is running by a 100VAC power supply, or the
battery voltage drops while the pump is running by the DC power supply, the following
processing is executed according to the power supply fault stop setting. The power supply
fault stop setting is set to ON by default. When the pump is being driven by the DC power
supply, set the power supply fault stop setting to ON.

Delay Time / Start Time
ON (Default setting)
After a recovery from a power failure, the power voltage fault is
displayed and pump operation is discontinued.
OFF
•
When the power failure is recovered before the sampling start
time, pump operation is continued.
•
When the power failure is recovered after the sampling start
time has been exceeded, an ON timer setting error is
displayed and pump operation is discontinued.
* The sampling start timer for the Delay Time setting is the time obtained by adding the
Delay Time set time to the time when the [START/STOP] key is pressed (i.e. the time
when the ON timer is started).

ON (Default setting)
The power voltage fault is displayed and pump operation is
discontinued.
OFF
Pump operation is continued even if the battery voltage drops.
There is the risk that the DC power supply might overdischarge.
So, when the pump is being driven by the DC power supply, set
the power supply fault stop setting to ON.
