NOTES
A Pneumatic Remote Control (Air Switch) consists of an air button (air pump, transmitter), a pulse switch (air
Sensor, receiver) and a relay (either alternate action or stepper). The air button is connected to the pulse
switch by the air hose. By pressing on the air button at one end of the air hose, the increased pressure will
momentarily close the contacts of the pulse switch at the other end of the air hose, thus energizing the coil of
the relay. The relay turns ON or OFF the connected equipment.
1. An air button with ruptured seal or bellows inside, will not produce sufficient air pressure to operate the
momentary air switch and could lead to total break down.
2. Water in air hose will damage the pulse switch and it is caused by a faulty air button (see note 1 above) or
condensation. In either case, it must be drained and the cause found and corrected. To reduce condensa-
tion, protect the air hose from exposure to direct sun, ice or frequent temperature fluctuations.
3. A defective relay is either due to contact or coil failure. Contact failure is caused by over-load or cross-
wiring and coil failure is caused by 240 volt connected across the 120 volt coil or permanently applied 120
volt. (The relay is designed for intermittent duty only). Permanently applied 120 volt could be the result of
water in the air hose (see note 2 above) or a spa cover placed over (and depressing) the air button. In any
case, the cause must be found, corrected and the relay replaced.
