HIGH/LOW PRESSURE FAULT LAMP
EXPLANATION:
a. Low Pressure Fault: The System is equipped with a
Low Pressure Switch. With no pressure applied to
the Low Pressure Switch it does not allow the
System to operate. With pressure above 6 psi
applied the switch closes and allows the System to
operate. If the system pressure should fall below 6
psi, the “HIGH/LOW PRESSURE” lamp blinks.
After 20 seconds, the system shuts down
completely. The “HIGH/LOW PRESSURE” lamp
remains lit until the “Fault Reset” button is
pressed, or the system power is interrupted.
b. High Pressure Fault Lamp: The System is equipped
with a High Pressure Switch, which stops the
system if pressure exceeds 950 psi.
After a fault has been corrected and the “Fault Reset”
switch has been pressed, repeat Step 11.
SOFT START OPERATION:
The Horizon Seafari system may have a Soft Start
installed. This Soft Start reduces the current (amps)
required at startup for single-phase systems. This is
accomplished by reducing the startup torque of the motor.
There are a few things one should know when operating a
system equipped with a motor Soft Start.
Never start the system without the Back Pressure
Regulator Valve [33] open fully. The reduced torque
available to the motor is not sufficient to turn the high-
pressure pump when the Back Pressure Regulator
Valve is adjusted to 850 psi. Starting while the Back
Pressure Regulator is not fully open causes damage to
the motor.
The Start Sequence for a system equipped with a Soft
Motor Starter is as follows:
1. When the “Start” switch is pressed, power is
present at the Soft Start.
2.
The Soft Start immediately begins its starting
cycle.
3.
After a few seconds, the motor reaches full speed
and the High Pressure Pump contactor makes an
audible click and is switched on.
The Soft Motor Starter has a 30 Amp circuit breaker
on its enclosure. When the circuit breaker trips, the
Soft Starter power does not ramp properly. Check the
motor wiring and Soft Start to spot any wiring
problems. Reset the breaker inside the controller
before repeating the start sequence. If the circuit
breaker interrupts power repeatedly, the system may
require service.
The Soft Starter is equipped with a temperature
sensor. The temperature sensor is designed to stop
operation when the Soft Start overheats. Before
restarting the system, the main power must be
disconnected to reset the Soft Start’s logic.
Overheating occurs when the system is exposed to
extreme heat or it is started and stopped repeatedly
over a brief span of time.
