DESCRIPTION OF PRODUCT ..
The 536/537 Series AutoSwitches are automatic switchover systems designed to provide a
continuous supply of high purity gas. These units may be configured with or without the connections
to connect to both high pressure and liquid cylinders. The primary bank (left side) of the AutoSwitch
system is configured for use with liquid cylinders, pressure up to 600 PSI(41 bar). The reserve bank
(right side) is configured for high pressure cylinders filled up to 3500 PSI (241 bar). The standard
AutoSwitch system will maintain a regulated line pressure within the values shown in the table
below:
MODEL RANGE
536 2XXX 0-50 PSI (0-3.5 BAR)
537 2XXX 0-50 PSI (0-3.5 BAR)
536 3XXX 0-100 PSI (0-7 BAR)
537 3XXX 0-100 PSI (0-7 BAR)
The continuous working inlet pressure on the primary bank (liquid cylinder) must be above 140 PSI
for the system to operate properly. When the primary bank falls below this value, gas will be pulled
from the reserve side.
Models of these AutoSwitches are available with or without pressure switch gauges. Models with
pressure switch gauges can be configured for use in conjunction with an optional remote alarm.
They cannot be connected directly to AC line voltage. Models with pressure switch gauges include
a power indicator light and LED status lights to indicate the condition of the gas cylinders. A green
indicator light signifies a
“Normal” condition, while a red light indicates an “Alarm” (gas cylinder
empty) condition. The pressure switch AutoSwitch systems also include a strain relief on the bottom
through which wiring can be connected to an internal circuit board and to a remote alarm such as
CONCOA’s Altos 2 *.
