Features

Motor Soft-Start
Normally, when there is a demand for water and power is available, the Fhoton™ Drive will be operating. Whenever the Fhoton™ Drive
detects a need for water, the controller always "ramps up" the motor speed through a gradual increase of motor voltage, resulting in
a cooler motor and lower start-up current compared to conventional water systems. In cases where the demand for water is low, the
system may cycle on and off. Due to the controller's soft-start feature this will not harm the motor.
Level Control Switch(es)
Level control switch(es) can be wired into the Fhoton™ Drive for water level control. This is optional and is not required to run the Fhoton™
Drive. The controller can be used with none, one, or two control switches. This provides the user maximum adjustability when using the
Fhoton™ Drive. (See Installation section page 17 for more information on installing and using control switches.)
System Diagnostics
The Fhoton™ Drive comes equipped with an LED indicator to convey operational status to the user. When operating normally, the LED will
indicate solid green (IDLE condition) or flashing green (RUNNING condition). While in the RUNNING condition, the flash sequence count
indicates rotor speed. A flash sequence is defined as follows: LED On for 0.5 seconds, LED Off of 0.5 seconds. Each sequence is separated
by a 2 second Off time to give a clear visual indication between flash sequences. Flash sequences and cycles apply to both the red and
green LED.
As an example, a 4 flash sequence of the green LED indicates an operating speed between 35 and 45 Hz.
(See Table 1. Rapid Flashing Green Light).
The Fhoton™ Drive continuously monitors system performance and can detect a variety of abnormal conditions. In many cases, the
controller will compensate as needed to maintain continuous system operation; however, if a high risk of equipment damage exists, the
controller will protect the system and indicate the fault condition via a flashing red LED. If possible, the controller will try to restart itself
when the fault condition subsides (see Troubleshooting section page 21 for a list of Fault Codes and correction actions). The following
sections detail the conditions in which a fault will occur.
