Impulse Generators Adjustable Pulse
The Impulse Generator is a device which is used in a pilot signal line to produce a momentary pulse of air in order to eliminate the possibility of a held-on signal. The pulse duration is fully adjustable. Once adjusted the screw protection cover can be re-fitted to avoid tampering. Impulse Generators are installed in-between the signalling valve (normally a 3/2 valve) and the pilot valve being actuated. The signal from the 3/2 valve is maintained at
port 1 of the impulse generator, which then activates a single air pulse to operate the pilot valve. To repeat the cycle the pilot signal must be exhausted and applied again.
