STARTING THE SYSTEM
Section 7
(continued)
Motor Rotation Direction
If the pressure/flow seems low or the system is indicating Motor Overload error check the motor rotation
direction. Turn the breaker/disconnect switch to the off position and wait 5 minutes. Switch any two leads on the
controller output (T1/U, T2/V or T3/W). Turn the breaker/disconnect switch to the on position. Observe pressure
and flow. If the pressure or flow still seems low check plumbing.
For CentriPro Motors, connecting T1/U to Red, T2/V to Black and T3/W to Yellow will give the correct rotation.
NOTE
It is possible for the pump to maintain constant pressure with a low flow or a high suction head even if the
pump is rotating backwards. While the pump is running use an amp probe on one of the output power leads
connected to the motor and compare the current draw between the two rotation directions. The lowest
current reading indicates the pump is running in the correct direction.
System Status
The status indicator light displays the status of the controller. A constant green status code indicates that the
pump is in standby mode (pump not running). A blinking green status code indicates that the pump is running. A
constant orange light indicates the input voltage is low. A blinking or constant red light indicates a problem with
the controller or system. Refer to the access cover side panel for a list of status codes. See Section 9 for more
details.
DANGER
The status code indicator light is not a voltage indicator! Always turn off disconnect switch and
