*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 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.
