Preset and programmable behaviors for the Wellington ECR 2 26W motor

Here's an overview of how the preset and programmable behaviours work in Wellington's ECR 2 26W motor.

Control wire states

Motors with the black control wire (three wire motors) have three valid states. If you change these states, you will
change the operation of the motor. The three states are: 

  • Black wire not connected (to phase or Neutral)
  • Black wire connected to Phase
  • Black wire connected to Neutral

You can change the black control wire connection at any time.

You can also configure motors without the black control wire (2 wire motors); however, they only have one state. 

Each of the following functions start either when the cooler powers on, or after a change in the control wire state.

Operating functions

Each control wire state/ polarity can have a speed, direction and an optional timer assigned (Step 1).
When the timer is enabled a second set of speed and direction can be assigned (Step2).

Sequence

Step 1: 

  • When the control wire changes polarity (i.e the control wire is switched from Phase to Neutral), or when the motor is first power on, the speed and direction assigned to step 1 are used.
  • If the timer is disabled, the motor will operate in Step 1 continuously.
  • If the timer is enabled the motor will automatically switch to step2 when the timer stops

Step 2:

  • The motor will use the second set of speed and direction assigned to step 2
  • The motor will continue to operate in this step until the control wire state is changed or the motor is powered off.

Speeds function
The motor speed can be set from 300 – 2300rpm. 

The motor can also be assigned to Stop (0 speed) – this is generally used in conjunction with the timer function.

Direction function
The direction of rotation can also be set to either CW (clockwise) or CCW (Counterclockwise). The direction is 
observed from the drive end of the motors where the fan connects.

Timer function (optional)
When using the Timer function, you can set the motor to run from 0 seconds up to 3600 seconds (1 Hour) with the programed speed and directions assigned to step 1 

  • If the timer is set to 0 seconds, the timer is disabled, and step 2 is disabled.
  • If the timer is set from 1-3600 seconds, then the step 1 timer is enabled
