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.

APPENDIX A: CRS+/ CRS M3 BUFFER TANK SETTINGS

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.
