Fault / Service Indications – Requiring Operator Intervention.
1, 2 & 3
Fault stop:
Once the problem has been cleared the fault can be re-set by one of the
following procedures.
i)
Units fitted with an Alpha-numeric display:
Power the unit right off, using the local
isolator (not the unit on/off switch), waiting ten seconds then re-applying power. When the
message “Cylinder x drain fault” is once again displayed press the o.k. button, and the unit
will revert back to it’s operational state.
ii)
Units not fitted with a display:
Power the unit right off, using the local isolator (not the
unit on/off switch), waiting ten seconds then re-applying power. When the constant amber
“drain fault” indication is showing, press the unit “fault reset” button, which is located on the
fascia above the “Vapac” Logo.

Service Interval Expired / Low Output:
Will be seen if either of the following occur.
a) Service Interval Expired:
Seen if the unit has run for a period exceeding the service
interval of 4500 hours.
b) Low output:
Seen if the cylinder has failed to reach 80% of the demand current after 30
hours run, or if the cylinder achieves this, then the current is monitored and an alarm
generated if the current subsequently falls to less than 60% of the demand current for
period of 4 hours run time.
If this indication is seen the cylinder should be inspected as soon as possible
If it is not convenient to carry out this inspection immediately it is possible to
postpone it for a short time.
3.4.1
To Postpone the Sevice:
Press the reset button once:
The appropriate cylinder LED will change to constant “amber”
and the external alarm will be reset, allowing the unit to continue to run without an external
alarm.
a) Service Interval Expired:
If the original alarm was due to this, the alarm will
be reinstated after the unit has run for a further 120 hours.
b) Low output:
If the original alarm was due to this, the low output timer will be
reset and a new alarm will be generated if the unit fails to exceed 60% of the
demand current after a further four hours run time.
