Pump Over-Current Protection
The pump has built-in over-current protection to protect
the motor. In cold weather installations, if the grease
freezes causing the motor to draw more current; the
motor will try to start the pump 90 times before shutting
down.
How Over-Current Protection Works
When the pump is unable to start the ON Time cycle, an
over-current condition is created:
a.
The pump immediately goes into the set OFF
Time mode.
b.
At the end of the OFF Time mode the pump
again attempts to run the ON Time cycle. One
of two results are possible at this point:
• the pump runs the ON Time cycle as
scheduled and normal cycle operation
begins.
• the pump is still not able to start (condition is
still in over-current) and the immediately goes
into the programmed OFF time again. This
will repeat for 90 times before shutting down
entirely.
