6.1 Out-of-balance Detection and Balancing for Wash-
er-extractors
BNCLUF01.C01 0000185905 E.2 G.5 G.6 4/15/21 9:16 AM Released
This document describes how the out-of-balance (OoB) detection and machine balancing features
work on MilTouch™ washer-extractors to mitigate vibration before and during extract steps in a
wash formula. The OoB detection feature is provided only on certain machine models, as listed.
The machine balancing feature is only available on 72046M5K models.
Consult this document if your washer-extractor:
• experiences persistent recycles, or
• consistently cannot reach the programmed extract speed.
6.1.1 Out-of-balance Detection with a Vibration or Excursion
Switch
BNCLUF01.C14 0000339975 E.2 G.5 A.4 4/14/21 3:58 PM Released
Throughout an extract step, the machine monitors the vibration switch or the excursion switch
and performs a recycle if the excursion or vibration switch trips due to imbalance. In a recycle,
the machine will decelerate to a stop, reverse a few times in wash speed, then redistribute in drain
speed to balance the load. After every recycle, the machine will attempt to achieve the pro-
grammed extract speed again.

6.1.1.1.1 If the Extract Step is an Intermediate Extract
BNCLUF01.C04 0000185936 E.2 G.5 G.7 4/15/21 11:42 AM Released
The OoB detection process begins when the cylinder reaches drain speed.
1. The OoB detection system compares the amount of imbalance to a table of threshold values.
• If the imbalance is less than the lowest threshold value, the machine completes the extract
step at the programmed speed.
• If the imbalance is greater than the lowest threshold value, the machine completes the ex-
tract step at a reduced speed that is proportional to the amount of imbalance.
2. The OoB detection system continues to monitor the imbalance until the end of the step.
