The pump is equipped with an OVERRIDE feature, which can be engaged to temporarily run at higher or
lower speeds between 600 to 3450 RPM. Once override duration has elapsed, the motor will automatically
return to programmed schedule.
1. Pressing the OVERRIDE key; while the motor is running; will cause the motor to start running in the
OVERRIDE mode at the programmed Speed and Duration. The “active step LED” for OVERRIDE will
illuminate. The speed and duration settings LED along with its respective bar graph LED of OVERRIDE
shall blink back and forth at three (3) seconds.
2. The UP (+) / DOWN (-) arrows allow the user to configure Speed and Duration. These settings can be
changed while the motor is
running
. These settings are stored each time the UP (+) / DOWN (-) arrows
are pressed.
NOTE: When the OVERRIDE duration ends, the motor resumes the 24 hour duration cycle and will start
in the corresponding STEP. The OVERRIDE duration will
not
affect the start or stop times of the 24 hour
cycle.
NOTE: Pressing/Holding OVERRIDE key for more than three (3) seconds will cancel OVERRIDE mode.
NOTE: During the OVERRIDE mode, the motor will not start with the priming sequence.
NOTE: Pressing STOP at any time turns the motor OFF and clears the start time for the 24 hour schedule.
Override
Freeze Protection will run the motor at 2600 RPM for eight (8) hours if the ambient temperature drops
below 39° F. Once this eight (8) hour duration has elapsed, the motor control will check the ambient
temperature again. If the temperature is still below the 39° F threshold, the motor will run for an additional
eight (8) hours. If the temperature is above the threshold, the motor will
automatically
return to the 24
hour based schedule.
NOTE: The freeze protection function will
NOT
operate if the START button is not pressed. This can be
confirmed by verifying that the START LED is illuminated
.
Freeze Protection
Communication
Control with Digital Inputs
The user can run the motor at the programmed STEP 1, 2, 3, or OVERRIDE speeds by utilizing the four
(4) digital inputs. STEP 1, 2, 3, or OVERRIDE are equivalent to Digital Input 1, 2, 3, or 4 respectively.
The controller is rated to accept digital inputs of 18V-30V AC (24V AC+/- 20%) and 9-30V DC (12/24 V
DC +/- 20%).
NOTE: The motor will detect either a 50/60Hz for AC input or an active low signal for DC digital inputs.
The items below describe the functionality of the digital inputs: (See Figure 7)
1. If the user provides any one of the 4 digital inputs, then the DURATION LED will blink every one (1)
second to indicate the Digital Input is functioning properly.
2. The motor will illuminate the corresponding “active step LED” and the respective bar graph LED. The
START LED will be OFF when a digital input is present.
