Low Level Switch
When the oil reservoir is full, the low level float (
llf
) sits in
the high, raised position as shown in F
As oil is dispensed, the low level float begins to travel
down. When the oil in the reservoir reaches low level,
the fully traveled down float (shown in F
. 11) closes
the normally open low level switch and a low level signal
is sent to the lubricator controller (J).
To clear the low level fault/error:
•
Check that
input supply oil line (CC)
is connected
and that the oil flow is continuous to
reservoir (K)
.
•
Loosen the
cock valve (BB)
from the
pump reser-
voir cover (L)
to bleed out the air.
Shut Down

a.
Close the b
leed-type master air valve (F)

Turn off electrical supply to the
lubrication con-
troller (J)
.
c.
Close the
shut-off valve (V)
on the
oil input
supply pump/system (DD)
