Operation Instructions
4.2.1 Automatic Mode—Let-Down Delay
To allow enough time to attach the milking unit to a cow and
for the cow to let down her milk, the control features a ‘De-
tach override’ or Let-Down delay. This delay lasts 2.0 minutes,
but can be programmed for any time from 30 seconds to 240
seconds. From the moment you press the Attach/Detach key
to milk a cow until the delay ends, this override prevents the
milking unit from detaching, whether milk is measured or not.
During the delay period, whenever a high enough ow rate is
sensed (determined by the preset ow rate), the control reg-
isters milk ow and signals the LED Status Indicators to turn
green.
Anytime a low milk ow rate is calculated at or after the de-
lay’s end, the control will Detach. Depending on when the low
rate occurs, the Detach will either be “early” or “normal” and
related events will differ accordingly.
4.2.2 Automatic Mode—Early Detach, at end of
Let-Down Delay
A Detach that occurs when the Let-Down delay ends is con-
sidered an early Detach. Upon early Detach the milk shutoff
valve shuts off vacuum to the claw, gently detaches the milk-
ing unit from the cow and retracts the link arm. The No Milk
lamp starts ashing (indicating an early Detach) and the me-
ter empties its contents.
You may continue milking the cow after an early Detach by
reattaching the milking unit to the cow. The Manual key (U1 or
U2) can be pressed before or after the Attach key is pressed.
4.2.3 Automatic Mode—Normal Detach
A normal Detach is any detach that occurs after a point when
a below-minimum milk ow rate exists long enough to activate
the Detach.
When a below-minimum milk ow is sensed, the takeoff delay
will start. The LED Status Indicators on the TouchPoint will
ash green constantly for the duration of the delay period or
until the level sensing probe is activated. If by the end of the
delay the cow does not resume a minimum ow rate, the claw
will detach. The LED Status Indicators will turn white to indi-
cate a normal Detach.
If normal Detach occurs too soon for a cow with unusual let-
down or milk-out problems, you may continue milking the cow
after Detach by reattaching the milking unit to the cow.
— NOTICE————————
Flashing LED Status Indicators may
indicate an early Detach. The milking
unit was attached to a cow for only
the Let-Down period.
