4. Controlling the pump
Install a timer on a machine to be lubricated, and make
the operation and pause cycle settings of the three-way
solenoid valve for driving the pump.
Make sure that you make this setting in the
operation/pause cycle. In continuous operation
(when the power is turned on), oil is discharged
through the valve only once. After that, no oil is
discharged, so that points of lubrication will be in
an unlubricated condition.
The solenoid valve for air supply must be a
three-way solenoid valve. Air in the pump is
discharged through the three-way solenoid valve
during a pause.
The pump on the machine side is powered on.
The solenoid-valve timer for driving the pump on the machine
side is on.
The solenoid-valve timer for putting the pump on the machine
side into pause mode is on.
The timers in and above turn on and off repeatedly as
illustrated below.
