*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 sufcient. 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.
