TANK PLACEMENT
1. Make sure the buffer tank is on a solid foundation. Use a level measuring instrument.
2. When a milk pipeline is placed at 30cm above the ground, there must be no walking
space between the buffer and the main tank.
3. The buffer tank should be located nearby or above the drain.
4. The best position to install your buffer tank is in front of the main tank. The distance
between the main tank and the buffer tank should be as short as possible. This will re-
duce operating costs and contributes to the deflate process.
AIR SUPPLY
A 6mm airline should be connected from the compressor to the valve block in the CRS+. 4mm airlines
must be connected to the butterfly valves underneath the buffer tank. The air pressure should be be-
tween 6 and 8 bars, to control the butterfly valves.
N.B. The air pressure to the butterfly valves should not be more than 8bar.
CLEANING
Clean the robot a couple of hours before using the buffer tank. When you do not do this, the robot
may proceed with the main cleaning process when the milk tank driver empties to the main tank.
English
MOUNTING INSTRUCTIONS

Buffer Tank | 6
INSTALLATION METHOD
1. Put the buffer tank into position.
2. Loosen all the lock nuts with the wrench.
3. Level your buffer tank by turning the leveling feet in and out as necessary.
4. When your buffer tank is level, tighten the lock nuts
using the wrench. Do not move your buffer tank unless
you tighten the locknuts. This may result in damage to the
leveling feet. Ensure that the buffer tank is stable.
5. Mount the air in/outlet (white elbow) on the top of the
buffer tank. Make sure this part is open and clean at all
times.
To make sure the buffer tank will not fall over, we recom-
mend attaching the cleaning pipe to a wall.
6. Make the tube/pipe connections according to the illustration beside. Connections can be made
with Pex or stainless steel.

Milk goes directly into the
mechanically refrigerated
main tank.
Milk goes into the buffer tank.
The main tank is being clean-
ing and rinsing.
The robot, milk pipeline and
buffer tank are being cleaned.
Milk is stored in the mechani-
cally refrigerated main tank.
Incorrect use of the buffer tank can be dangerous to people, nearby equipment and the environment. Before
reaching into the buffer tank, disconnect the air tubes of the CRS.
TROUBLESHOOTING
Issue Cause Action
Valve does not open or close properly Valve is broken Disassemble and replace part.
No voltage, no air pressure Check power supply, use air pressure to
check the valve
Buffer tank does not discharge water
properly No pressure Disassemble and check the air valve block, increase the pressure.
High bacteria-count number Insufficient cleaning of the robot,
main tank or buffer tank
First check your robot cleaning, then sprin-
kle ball. Check for congestion in the tank
valve system.

Connect the valves of the buffer tank with 4 air tubes (4mm, black PA) into the CRS+. Use the prede-
fined cluster configurations in the Lely CRS+ manual for the right settings and connections.
Menu item Description Min Max Default Unit
Maximum contents
The maximum content of the buffer tank is used
for an internal calculation to make sure the buffer
tank does not overflow.
200 2500 500 Kg
An alarm is generated when the buffer tank is full
(based on yield calculation of the milking robots).
All milking robots in the cluster will be taken out
of operation.
-441 -5511 -1102 (lb)
Maximum buffer time
The maximum time the milk is stored in the buffer
tank. When this time is expired, the milk will get
drained to the sewer. 4360 90 min
An alarm is generated when the set time is ex-
ceeded.
Buffer emptying time
The maximum time to allow the buffer tank to
transport the milk to the milk tank. This is based
on a full buffer tank.
360 60 min
The drain time depends on:
The location of the buffer tank concern-
ing the milk tank.
The amount of milk in the milk tank.
A sensor can be connected to the CRS+ indicating
when the buffer is empty.
If this sensor is installed, an alarm is generated
when the set time is exceeded.
The drainage pauses when a milking robot pumps
milk to the milk tank. The drain timer takes this
pause time into account.
Pre-rinse delay *
During pre-rinse valve V6 or V6b switches to
buffer after the set delay time. This is to prevent
milk residue to enter the buffer tank.
30 600 30 s
* Applicable for USA / Canada only.

Until May 2019 Valve plug connection
The level sensor is mounted at the lowest possible position in the tank valve
system of the buffer tank. The figure shows the correct wiring between the
level sensor and the CRS+ (3x 0,75mm2).
Note: When the red and green led lights are on, the buffer tank is empty.
From May 2019 M12 connector
A 3 or 4-wire cable is delivered with the system (colors brown, blue, black, [white])
CONNECTION LEVEL SENSOR TO CRS+ OR CRS M3
The sensor can be connected to an input of the CRS+ or CRS M3. Configure the setting: “BV is EMPTY
(BV1)” at ‘configuration inputs’. At ‘test inputs’ the state of the level sensor can be checked.
Check the functioning of the system at the first milk collection! Check the wiring if the “empty tank”
procedure does not work well.

There are two options that you can choose:
• 203001 Electrical acted 3/2 valve
• 203008 Pneumatic acted 3/2 valve
The Pressure Reduce Valve should be adjusted as high as possible. In this situation the system will
work optimal.
MAX PRESSURE 1 - 1,2 bar!
203001 - Electrical acted 3/2 valve
