UNDERLOAD
OR LACK OF FLUID
Coyote shuts off the pump within
one second of running dry, and automatically
restarts the pump at any time you dial on the
timer from one minute to twelve hours. trip

OVERLOAD
If Coyote shuts down the pump due
to excessive current, it will restart it sixty
seconds later. If the motor draws normal current
Coyote will allow it to run. If, however, after
two consecutive attempts one minute apart the
motor continues to draw excessive current, Coyote
locks out the pump so as not to burn out a motor
winding and the overload light changes from on
steady to blinking. The standard overload trip is
120% of normal. An option of 200% is available by
cutting a trace on the front of Coyote and can be
done in the field. |
VOLTAGE FAULT
Coyote will trip on voltage if the
voltage varies more than 10% from the operating
voltage chosen.
An option of 15% is available by cutting a trace
on the front of Coyote and can be done in the
field.

RANDOM
START
When energizing Coyote by turning
on power at circuit breaker or fused disconnect
there is a delay of 4 to 10 seconds before Coyote
turns on the pump. This "random start"
feature is designed to prevent many pumps served
by a single power source from all restarting at
the same instant when power is restored after a
power outage. |
ALARM
If you wish to ring a bell, light
a light, or activate some other alarm, Coyote's
normally open dry alarm contact closes on any
fault condition. For pumps that are expected to
run dry but no alarm is wanted, an option is
available to disable the alarm function on
underload (run dry) only by cutting a trace on
the front of Coyote and can be done in the field. |

SOFT START
For pumps using a soft start feature, a delay on
start-up of fifteen seconds before Coyote looks
for voltage, overload, or underload is available
by cutting a trace on the front of Coyote and can
be done in the field.
|
COLD START
For self-priming pumps that are pulling from a
pond through an empty suction line, a cold start
option of five minutes before Coyote looks for an
underload (run dry) condition is available by
cutting a trace on the front of Coyote and can be
done in the field.
