TROUBLESHOOTING
Symptom
Cause
1.
Gas leakage at the line regulator outlet when the
adjusting knob of the line regulator is completely
backed out.
2.
With no flow through the system (downstream
valves closed and adjusting screw in) line
pressure steadily increases above set pressure.
3.
Gas leakage from spring case (adjusting screw/
knob end of regulator).
4.
Gas leakage from any joint.
5.
Excessive drop in working pressure with
regulator flowing gas.
6.
Gas leakage from relief valve.
7.
Gas leakage from any gauge.
8.
Gauge does not return to zero when not under
gas pressure.
9.
Gauge does not consistently repeat the same
reading.
10.
The system makes a noise or hums.
1. Regulator(s) have malfunctioned. Replace or
repair.
1. Inlet gauges not reading pressure.
1. Check that the valves on the cylinders are opened. If
using a manifold system, check that the valve on the
manifold is opened.
1. Switchover system seems to be using gas from
the primary and reserve cylinders
simultaneously (pressure is decreasing on both
inlet gauges at the same time.)
1. Observe the inlet pressure. It may be necessary to
do this during times of the heaviest use. If the inlet
pressure is less than the values listed below, replace
the high pressure cylinders.
536 2XXX
140PSI (10 BAR)
536 3XXX
140PSI (10 BAR)
537 2XXX
140PSI (10 BAR)
537 3XXX
140PSI (10 BAR)
If the inlet pressure increases significantly when the
system in not in use, then the system is over-
withdrawing the liquid cylinders. Additional capacity
may be added to the system to prevent this.
1. Power light is not on.
1. Check that the remote alarm is powered on.
2. Check that the cable between the AutoSwitch and
the remote alarm is wired correctly.
3. For models with a circular connector on the
AutoSwitch, check that the cable connectors are
properly plugged in at both ends.
1. Status lights are not on.
1. Check that the remote alarm is powered on.
2. Check that the cable between the AutoSwitch and
the remote alarm is wired correctly.
3. For models with a circular connector on the
AutoSwitch, check that the cable connectors are
properly plugged in at both ends.
