Frequently Asked Questions
What does it do?
Coyotes protect pumps from running dry,
from overload, and from bad power. There is no plumbing and no
probes. They are built rugged for tough jobs.
On what kind of pumps does it work?
Submersibles, centrifugals, jets, and sumps
In what kinds of applications?
Water wells, oil wells, booster and lift
stations, chemical transfer, mine dewatering, sewage treatment,
solution mining, food processing, construction dewatering, and
cleanup of aquifers contaminated by hydrocarbons are the most common.
How does it work?
Coyote monitors the incoming power and the
electrical characteristics of the motor. When the pump quits
pumping fluid, those characteristics change, and the Coyote shuts it off.
What if there is not enough fluid to pump when the pump restarts?
Coyote will let it run just one second,
shut it off, wait the time dialed on the timer and try again, until there is enough to pump.
What if I want to turn on the pump before the timer has run its cycle?
Just push the RESET button or turn the
power off and then on again at the circuit breaker and the pump will restart.
Do I have to order a different Coyote for each size motor?
No. Each Coyote model covers a wide
horsepower range and will operate on any
motor in that range.
Will it work on power supplied by generators and phase converters?
Coyotes will operate with generators and
rotary phase converters..
What about protection from the environment?
The insides of Coyote are sealed in plastic
to keep out moisture, insects and blowing sand and dust.
What about power outages?
When the power is out, the pump won't
run. When it comes back on, Coyote
automatically resets itself. There is no need to touch anything.
What about lightning induced power surges?
Rugged and effective protection for the
electronics of Coyote is built-in.
What about alarm contacts?
All Coyotes except the Mini, Basic & PS
models have contacts to activate an alarm (bell, light, pulse) on any
