Pneumatic timer controller for Auger samplers

The purely pneumatic control system is housed in a Rittal housing. 380Bx380Hx210T and corresponds to the supplied Pneumatic plan "Drive + R Screw". There are 3 timers (cleaning/sampling / pausing) which can be set in the time range up to 30 seconds can be set. If other time ranges for the timers are set are desired, these would have to be requested separately. Functional sequence: The sampling cycle can either be controlled by a rocker arm valve or by push button valve. Start - The cycle always starts with cleaning - After the cleaning time has elapsed, sampling begins. - After the sampling time has elapsed, the pause begins . - After the pause time has elapsed, cleaning starts again, etc. - If the start signal is omitted, the screw stops. - At the next start, the cleaning starts again.
