Cleanings and Rinses
A cleaning or rinsing starts:
• Automatically with the settings in the E-Link or T4C.
• Manually when started on the E-Link or CRS web interface.
A rinsing or cleaning is done when the robot arm is in the home position.
The following rinsings and cleanings are available:
• Lelywash.
• Local rinse.
• Cluster cleaning.
• Milk line rinse.
• M4Use flush.
• TDS II screen cleaning.
• Local main cleaning (only USA cleaning).
Lelywash
All parts that make contact with milk from the teat cups to the pre-milk device are rinsed during a
Lelywash. A Lelywash starts after the number of milkings set on the E-Link, and on the settings in T4C. If
either the E-Link or the T4C settings indicate the need for a Lelywash, the Lelywash is activated. When the
number of milkings is set to 1 (default) and a Pura is installed, the use of steam depends on the settings in
T4C. If the water supply has a USA configuration and the USA cleaning is set, the Lelywash is done with
warm water with a sanitizer solution.
Local Rinse
During a local rinse, water flows through the milk jar, teat cups and milk tubes to the milk jar, and the pre-
milk device. All parts that make contact with milk from the teat cups to the 3-way valves on the robot unit
are flushed. If the water supply has a USA configuration and the USA cleaning is set, a local main cleaning
is done instead of a local rinse.
A local rinse starts:
• When a set interval time on the E-Link has passed since the last milking.
• When a set interval time on the E-Link has passed since the last rinsing or cleaning.
Choices are:
• Standard.
