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.
