When operating the
PN-COS-16
remotely by manual operation, an air regulator (with
relief function) that adjusts motive air pressure is required. Adjust the set pressure
with the air regulator while checking the pressure gauge on the secondary side.
Please set the position of the adjustment screw according to the steps shown in the
"Setting the pressure with an adjustment screw" on the following page.

Pressure at the secondary side can be switched manually between 2 points with an
ON/OFF switch. To do so, an air regulator (with relief function), which adjusts the
motive air, a 3 way solenoid valve, and an ON/OFF switch are required.
Pressure setting at the higher pressure side should be adjusted with the motive air by
checking the pressure gauge at the secondary side. For pressure setting at the lower
pressure side, follow the steps in the "Setting the pressure with the adjustment screw"
below.
Setting the pressure with the adjustment screw
Other than setting the secondary steam pressure of
PN-COS-16
using air pressure, it can be set by the adjustment screw.
・
To Maintain minimum required pressure by adjustment screw
Set the steam pressure at the secondary pressure side to a
minimum required pressure using the adjustment screw.
・
When setting the pressure using only motive air
Loosen the adjustment screw until there is no load on the coil
spring. The valve should be closed once there is no motive air.
