Retract Delay (soft take off)
The retract delay allows the vacuum in the claw to bleed off (diminish) before retracting the rope or
chain. This reduces the pulling force on the teats when removing the cups. Retract delay is
adjustable (see controls set up table)
Pull Time
The pull time is the amount of time the printed circuit board (PCB) sends a retract signal to
the detacher
’
s relay, which in turn sends power to the retractor motor.

Pull Time
After the Pull Time expires, power is again applied to the motor for the desired amount of time.
Sweep Delay and (On Time) Duration
The milk sweep removes any milk that might collect in the milk hose during the retract phase. The
Sweep Delay is the time between claw retract and when the vacuum sweep (vacuum to remove
milk) begins. The Sweep On Time is the duration vacuum is applied to the claw. Both the Sweep
delay and sweep

time are programmable, (see Control Set

up Table).
Pulsation Rate
This setting establishes the number of pulsation cycles per minute.
Pulsation Ratio (Front)
This setting determines the milk to rest ratio as a percentage on the front two quarters of your
milker unit.
Pulsation Ratio (Rear)
This setting determines the milk to rest ratio as a percentage on the rear two quarters of your
milker unit.
