Atlantic Water Gardens TidalWave Pump Protector - Manual (Page 4)

Application Summary
The Pump Protector is designed to help reduce damage to water pumps like
those used in outdoor ponds and pond-free water features. Pumps need water
flowing through the chamber in order to cool the motor windings. If water flow
is impeded, the pump can overheat, resulting in permanent damage. Water also
lubricates moving parts and therefore a loss of water flow can also damage these
internal parts.
Excessive water bubbles or a quick reduction in water flow creates small
changes in the line current to the pump. Additionally, a blockage from debris on
either the inlet or outlet side also causes small line current changes. The Pump
Protector control module is designed to detect these small changes and take ac-
tion to help protect the pump. Upon fault detection the control circuit will switch
off the power to the pump to protect it from over heating. Once tripped, the
user needs to inspect the water system to ensure adequate water flow is
established to the pump. Pressing the reset button on the control module once
will restart the pump.
The Pump Protector also has a calibration feature, which sets a high and low
protection threshold for each pump. To implement this feature, press the reset
button once and the buzzer will beep. Then press the button once between the
second and fifth beep from the buzzer. The unit will acknowledge by increasing
the tone of the buzzer. The control module is now calibrated to your pump. It is
critical that the water flow is checked for adequate movement before calibrating
the system to ensure that trip thresholds are set to normal operating conditions.
Some motors have thermal protection built in to help protect the pump. The
thermal protection will turn off the pump when hot but after cooling the pump
will automatically restart. Therefore the pump can get into a continuous on-off
cycle, which can result in permanent pump damage. The control circuit will detect
a thermal shutdown as a low current fault and switch off the pump to
eliminate cycling.

Instructions - Quick Set Up:
1. Connect pump motor to the pump power supply cord. (See figure 1.)
2. Plug the controller power supply cord into GFCI protected outlet. The pump
should start and buzzer will sound. (See figure 1.)
3. Ensure water flow is adequate in the conveyance lines and wait until the
buzzer stops.
4. Press the reset button once – the internal buzzer will pulse.
5. During the time between buzzer pulse 2 and pulse 5, press the reset button
once – this auto calibrates the unit to a power change range of plus or minus
10%. These settings will be permanently stored.
NOTE: Some pumps require a wider power change. Push the reset button
twice for a range of plus or minus 15%.
6. The buzzer will increase in tone frequency to acknowledge button depression.
7. The above process can be repeated if pump is changed or operating
conditions change.
