7.10.5 Moisture present in the carbon filter and/or the after filter
SYMPTOM Moisture present in the compressed air filter bank’s carbon filter
and/or after filter.
POSSIBLE
CAUSE
1) Automatic drain valve not functioning.
2) Automatic drain valve timer not properly set.
3) Vaporous moisture entrained in compressed air supply.
REMEDY
1) Press the manual override switch on the automatic drain valve. If
the drain valve does not open, check the power supply to the
drain valve.
2) Activate the manual override switch on the automatic drain valve
to check for proper function. If the override must be activated
several times to completely drain the accumulated condensate,
the drain valve’s timer should be adjusted. The timer on the
automatic drain valve can be set to cycle every 1 to 45 minutes.
The drain opening can be set for 1 to 15 seconds each cycle. To
minimize air losses, the timer should be adjusted to open the port
just long enough to discharge any accumulated condensate. The
timer is properly set if nothing but air vents at the end of the open
period.
3) The filters are not designed to remove vaporous water. The
incoming air must be cool enough to allow the water vapor to
condense. See Section 6 - N

7.10.6 No power to the electrical protection device
SYMPTOM
Helium compressor will not start.
POSSIBLE
CAUSE 1) Electrical protection device power cord not attached to helium
compressor.
2) Electrical protection device fuse blown.
3) No power supplied to the helium compressor.
REMEDY
1) Attach the electrical protection device power cord to the
receptacle on the front panel of the helium compressor. See
Section 6.
2) The protection device is fitted with three fuses. To gain access to
the fuses, open the enclosure door. The fuse block is fitted with
fuse covers that have indicator lights. The indicator lights are
illuminated only when a fuse is blown. Three spare fuses are
shipped with the system inside the enclosure. See Section 8 for
instructions on replacing a fuse.
3) Check the power supply to the helium compressor and verify that
it meets the requirements outlined in Section 5.
