10.1
THE COMPRESSOR.
10.2
If the compressor does not start when the PUMP switch is depressed, the problem
may lie with: (a) the compressor, (b) the pump fuse, (c) the pump switch, or (d) the
AC solid state relay.
10.3
If voltage is present when measured between terminals 8 and 4 of TS-1 (Figure 9),
the compressor is defective. Replace the compressor.
10.4
If voltage is not present between terminals 8 and 4 of TS-1, measure the voltage
between terminals 7 and 4 of TS-1. If not present, the pump fuse is blown.
REMOVE THE POWER CORD FROM WALL OUTLET WHEN CHECKING OR
CHANGING FUSES. Replace the pump fuse. Four-amp SLO-BLO for 120V or 2-
amp SLO-BLO for 220V.
10.5
If fuse blows after replacing, the compressor is defective. Replace the compressor.
10.6
If voltage is not present between terminals 8 and 4 of TS-1 but is present between
terminals 7 and 4 of TS-1, measure the voltage between terminals 6 and 4 of TS-1.
If voltage is not present after depressing the PUMP switch several times, the pump
switch is defective. Replace the PUMP switch.
10.7
If voltage is present between terminals 6 and 4 of TS-1 in Section 10.6, measure
the voltage between terminal 3 of the AC solid state relay and terminal 4 of TS-1. If
voltage is present, the AC solid state relay is defective. Replace the AC solid state
relay.
If the compressor continues to run after the PUMP switch is depressed to the off
10.8
position (as further evidenced by voltage not being present between terminals 6
and 4 of TS-1), the AC solid state relay is defective. Replace the AC solid state
relay.
NOTE:
There is an inaccessible thermal switch located within the compressor
body. If the cooling fan, Figures 5 and 8 (11), mounted on the back
inside wall of the generator unit should fail, the compressor will heat up
and shut itself off before incurring any damage. This cooling fan is sized
for a particular air flow and must only be replaced with the same fan.
See Section 13.0, Parts List.
SPECIAL NOTE: It is mandatory that the back panel of the electronics cabinet
(rack) be kept open for proper cooling of the rack-mounted pure air generators.
The compressor will shut itself off if the generator cooling fan cannot expel the
warm air from the cabinet.
