Pneumatic time delay
FIGURE 4-23: Pneumatic time delay
1. 3/2-way piston slide valve (there is no separate control connection because the control
input is internally connected to the pressurized connection [1])
2. Delay time setting range
3. Adjusting spindle with hexagon socket (secured with sealing wax)
4. Threaded connection G1/8
5. Sinter filter/Silencer
6. Factory-set delay time (30 seconds)
A - Pressure connection "pneumatic pilot line", coming from the pressure reducer for the nitro-
gen pilot cylinder (connection "A" is marked on the time delay unit and in the circuit symbol
with [1]).
B - Operating connection "pneumatic pilot line", outgoing to the extinguishing agent con-
tainer battery/extinguishing agent container group (connection "B" is marked on the time
delay unit and in the circuit symbol with [2]).
