8.2.1. LEAKING RESERVE SIDE RIGHT LEAKAGE OR LEFT LEAKAGE

The alarm starts in following situations:
Reserve side pressure is too low
Allocate the leakage using leak detecting spray. Isolate the leaking area and do repair/change
component or washer.
Check that the audible and visual alarms on the the Gas Alarm have been cancelled.
8.2.2. CHANGE OF OPERATING SIDE RESERVE CONN.
The alarm starts in following situations:
The supplying side is empty
EN
Replace the empty cylinders with full cylinders as described in chapter 7.
Check that the audible and visual alarms on the the Gas Alarm have been cancelled.
8.2.3. HIGH INTERMEDIATE PRESSURE
The alarm starts in following situations:
Intermediate pressure is too high
Check that the manifold regulator R1 & R2 outlet pressure is as preferred. If not, isolate the
regulators by closing valve V3 or V4 and check one regulator at a time. Start with the regulator
on reserve side, relief the pressure by the safety valve S1 & S2 and check if the pressure
increases again. Change operating side and make the same test with the other regulator.
If you shortly after resetting the regulator have the same alarm condition again, the regulator
most likely has internal leakage. Contact authorised service for replace the regulator with a
new or refurbished unit.
Check that the audible and visual alarms on the Gas Alarm have been cancelled.
8.2.4. HIGH DISTRIBUTION PRESSURE OP.PRESSURE HIGH
The alarm starts in following situations:
Distribution pressure is too high
Check that the distribution pressure is as preferred. If not, isolate the regulators R5 & R6 by
closing valve V9 or V10 and check one regulator at a time. Start with the regulator on reserve
side, relief the pressure by the safety valve S3 & S4 and check if the pressure increases again.
Change operating side and make the same test with the other regulator.
If you shortly after resetting the regulator have the same alarm condition again, the regulator
most likely has internal leakage. Contact authorised service for replace the regulator with a
new or refurbished unit.
Check that the audible and visual alarms on the Gas Alarm have been cancelled.
8.2.5. LOW DISTRIBUTION PRESSURE OP.PRESSURE LOW
The alarm starts in following situations:
Distribution pressure is too low
Check the high pressure gauges M1 & M2, if the valves V13 & V14 and cylinders valves are
open, if the cylinders are not empty or if there is a leakage. In this case replace cylliders or
make corrections on collection pipelines.
Check the intermediate pressure gauges M3, if the valves V1 & V2 and V3 & V4 valves are
open or if there is a leakage. In this case follow procedure as Intermediate pressure is too
high.
Check the distrubution pressure gauge M4, if the valve V7 & V8 is in correct position or
if there is a leakage. In this case reset regulators R5 & R6 one at a time by releasing the
pressure with the safety valves S3 & S4, start with the reserve side. Check if the pressure
comes back to normal, if not increase the distribution pressure
& R6 screw and check again. If the distribution pressure is still low, contact authorised service
for replace the regulator with a new or refurbished unit.
Check that the audible and visual alarms on the Gas Alarm have been cancelled.
