8.6 DuoControl switching facility
The DuoControl is an automatic switching facility with a remote display for a
two-bottle gas system. The DuoControl switching facility automatically
switches gas supply from the primary bottle to the reserve bottle as soon as
the primary bottle is either empty or no longer ready for operation. The gas
appliances may still continue operation. The DuoControl switching facility is
suitable for all commercial gas bottles from 3 kg to 33 kg.
Construction of the unit The DuoControl switching facility consists of a switching valve (Fig. 70,3) and
the operating unit (Fig. 71). The switching valve is mounted between the gas
tubes (Fig. 70,2 and 5). The knob (Fig. 70,4) on the switching valve is used to
select which of the gas bottles is to be used as a primary bottle and which is
to be used as a reserve bottle.
The switching valve is equipped with the regulator defroster "Eis-Ex". This pre-
vents damage to the gas system during the winter months.
Only the electrical functions can be switched at the operating unit (Fig. 71).
The regulator taps on the gas bottles (Fig. 70,1 and 6) must be opened man-
ually.
The switching valve provides a constant gas pressure, regardless of which gas
bottle is being drawn upon. The two indicator lamps on the operating unit show
the filling level of the primary bottle. The primary bottle is full when the green
indicator lamp (Fig. 71,6) lights up. The primary bottle is empty when the red
indicator lamp (Fig. 71,5) lights up. The gas is then supplied via the reserve
bottle.
