Testing with the Display Kit

4.2.2.
A kit consisting primarily of a vacuum fluorescent display and a wiring harness to connect the
display to the microprocessor controller is available from the Milnor
®
Milnor parts department for details.
CAUTION 11 : Avoid machine damage—Because of the additional power required to
operate the display, some components of the microprocessor controller may be damaged if the
display is connected for extended periods of time.

The controller begins the end-of-step routine when 15 seconds remain in any
bath step.
This pause allows the basket to slow before the inverter begins driving the
motor, possibly in the reverse direction.
The controller commands the inverter to drive the basket in the clockwise
direction at wash speed for 13 seconds in preparation for distribution.
The controller commands the inverter to gradually accelerate the motor from
wash to distribution speed.
The controller opens the drain 15 seconds after commanding distribution speed,
allowing goods to distribute evenly for less vibration. If the next step is a bath
step, the controller holds the drain open for 60 seconds, then commands it
closed.
The controller commands the inverter to maintain distribution speed for 45
seconds if the next step is a bath, or for 60 seconds if the next step is an extract.
Note 9: If the next step is a bath, the controller allows the basket to coast
for the last 15 seconds of the distribution time.

The controller commands the inverter to gradually accelerate the motor from
distribution to extract speed.
The controller commands the inverter to maintain extract speed for the
programmed duration. When the step timer expires, the controller signals the
inverter to stop driving the motor.
This pause allows sufficient time for the basket to coast to a stop.
Go to Chart 2
The controller unlocks the door latch 75 seconds after the end of the last step in
the formula.

Each step is either a bath step or an
