Solenoid Shifted Air Valve
*Special Conditions For Safe Use
A fuse corresponding to its rated current (max. 3*I
rat
according IEC 60127-2-1) or a
motor protecting switch with short-circuit and thermal instantaneous tripping (set to rated
current) shall be connected in series to each solenoid as short circuit protection. For
very low rated currents of the solenoid the fuse of lowest current value according to
the indicated IEC standard will be sufficient. The fuse may be accommodated in the
associated supply unit or shall be separately arranged. The rated voltage to the fuse shall
be equal to or greater than the stated rated voltage of the magnet coil. The breakage
capacity of the fuse-link shall be as high as or higher than the maximum expected short
circuit current at the location of the installation (usually 1500 A). A maximum permissible
ripple of 20% is valid for all magnets of direct-current design.
Solenoid Shifted Air
Distribution Valve Option
Warren Rupp’s solenoid shifted, air distribution valve option utilizes electrical
signals to precisely control your SANDPIPER’s speed. The solenoid coil is
connected to a customer - supplied control. Compressed air provides the pumping
power, while electrical signals control pump speed (pumping rate).
Operation
The Solenoid Shifted SANDPIPER has a solenoid operated, air distribution valve
in place of the standard SANDPIPER’s pilot operated, air distribution valve.
Where a pilot valve is normally utilized to cycle the pump’s air distribution valve,
an electric solenoid is utilized. As the solenoid is powered, one of the pump’s air
chambers is pressurized while the other chamber is exhausted. When electric
power is turned off, the solenoid shifts and the pressurized chamber is exhausted
while the other chamber is pressurized. By alternately applying and removing
power to the solenoid, the pump cycles much like a standard SANDPIPER
pump, with one exception. This option provides a way to precisely control and
monitor pump speed.
Before Installation
Before wiring the solenoid, make certain it is compatible with your system voltage.
