Oil
Red LED Lights if the valve is completely closed,
indicating a complete absence of oil.
A corresponding relay contact closes when
this LED is on. The terminal for this contact is
called
LL (Lower Limit) and appears in Figure
5 on page 9. This LED requires the user to
reset the system after resolving the oil
shortage issue (see
Resetting the
Dripmaster
on page 15).
