Solenoid Shifted Air Valve
Solenoid Shifted Operation
The Solenoid Shifted pump has a solenoid operated, air distribution valve in
place of the standard 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. The solenoid coil is connected to a customer-supplied control. 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 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.

*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.
