1. Introduction
Gala-Kool Pro is a universal tank control unit which combines all the
basic functions in one device:
- milk cooling control
- comprehensive cleaning control
i- an extended robot nterface
- an extended tank monitor
All basic functions can be selected and operated from the working
level. The control unit can also be adapted to a wide range of different
system types and sizes. This takes place through the thematically
organised parameter levels.
1.1 Function overview
Within the working level the control unit differentiates between various operating
modes:
OFF mode (stand-by)
Shows the current time
All LEDs are out
(Exceptions: outlet valve and tank monitor LEDs may be lit)
All output relays are deactivated
) (Exceptions: outlet valve and tank monitor alarms may be active
The other operating modes can only be selected from OFF mode. It is not
possible to switch directly between the different modes.
CAUTION: The control unit is live even when switched off.
Cooling mode
Two freely definable target temperatures can be selected by pressing a button.
If the milk temperature exceeds the selected target temperature (T1 or T2) by
the hysteresis value, the compressor contactor and agitator are switched on
automatically. Once the target temperature is attained, the compressor
contactor switches off, while the agitator continues to run for the set “after-
stirring“ period.
During cooling breaks the agitator switches on periodically, in accordance with
the set 'pause time', in order to ensure an even temperature throughout the milk.
Independently of this, during cooling, short or long “intermediate stirring” can be
switched on by pressing a button.
Cooling can be triggered in different ways:
manually using the “START COOLING“ button
via digital input “Remote start to cooling“
(by robot or external button)
automatically following cleaning (only in conjunction with robot)
Cooling now starts in accordance with the pre-set starting mode:
Immediately or after a cooling start delay, with periodic cooling boosts, etc.

Continuous stirring mode
From OFF mode, the agitator can be switched on by pressing a button and then
switched off again by pressing the OFF button.
Parameter [C25] can be used to set the time after which the agitator is to switch
off automatically.
The countdown can be interrupted at any time using the OFF button.
If [C25] is set to '0', the agitator will run continuously, but can be switched off at
any time using the OFF button.
Cleaning mode
The cleaning timer controls the water intake by time or level, as desired. All
running times (heater, pump, detergent injection) can be set separately. The
automatic switchover from acidic to alkaline detergent is also adjustable.
The controls the different processes and times fully automati-Gala-Kool Pro
cally.
Following a power failure the control unit will restart in the mode it was in
Robot interface
Depending on the parameter settings, the control unit includes a built-in robot inter-
face with the following functions:
- „Robot start / stop“ and
- “Butterfly valve open / closed“
These functions are controlled via the keypad.
Tank monitor function
During the entire cooling and cleaning process, the built-in tank monitor keeps check
on the correct operation of all components, in order to guarantee the perfect state of
the milk.
In particular, the following are monitored:
- minimum and maximum milk temperatures during cooling
- power failure (optionally power pack required!)
- agitator function (optionally agitator monitoring module required
- minimum and maximum temperatures during cleaning
- etc.
Any faults are indicated by two LEDs, and associated f codes flash in the display.ault
In the case of errors which may jeopardise the milk quality, the red LED “Don't add
milk” lights up.
1. Introduction

Page 6
The controller itself and the associated control circuits and load circuits must be pro-
tected separately and in accordance with the local regulations.
The separate protection of the control- and load circuit must be carried out according
to local conditions!
In order to prevent destruction of the relay or semiconductor relay outputs in the event
of a short-circuit, the load circuit should be fused to the maximum permissible output
current.
As well as incorrect installation, wrong parameter settings can also adversely affect
the correct functioning of the controller. For this reason, safety devices that are inde-
pendent of the controller should always be used, e.g. high and low pressure valves
or temperature limiters. Account should be taken of the local safety regulations in
this connection.
The load circuit (relay outputs K1 to K1 ) must be fused in accordance with the con-3
nected components.
The connection of external voltages to the digital inputs can lead to the destruction of
the control.
Caution: All cables to the digital inputs must be shielded and kept as short as possi-
ble. EMC.
Important note concerning the external fuse
The transformer, which is installed in the , has a two-chamber safety Gala-Kool Pro
winding, which is only short-circuit-proof due to the built-in thermal protection. If the
temperature exceeds 145 ° C, there is a risk of damage!
Protect control unit with an external fuse of 160mA!
2. Safety
2.1 Electrical safety

Universal tank controllers are designed to control systems, con-Gala-Kool Pro wash
densing units, alarms etc. in milk cooling tanks as well as to monitor milk quality. Fur-
thermore, connected milking robots can be controlled. Any other use of the device is
permitted only with prior written permission from the manufacturer.
The controller is intended only for incorporating into machinery, display panels or
switchboxes etc. and when fitted correspond to protection class 2 (double or rein-ing
forced insulation) It is only allowed to be put into operation in installed state. The use .
of the control is permitted in devices of protection class 1 and 2. The controller must
not be modified or converted in any way.
The controller is ready for use only when the parameters have been set universal tank
appropriately. Its use before this has been done would have no benefits and could also
damage the equipment or adversely affect the m to be temperature-controlled.ilk
Responsibility for the faultless functioning of the connected devices lies with the plant
engineer or the installer or the service engineer who has installed and commissioned
the .Gala-Kool Pro
The device is fitted with a resistance temperature sensor.
The controller is not suitable for use in explosive atmospheres. Danger of explosion.
Use only outside areas subject to explosive atmospheres.
The fulfils the EC requirements for electromagnetic compatibility Gala-Kool Pro
(EMC) and the Low Voltage Directive (LVD).
The safety components meet the VDE regulations.
2. Safety
2.2 Intended use
These operating instructions contain important technical and safety
information. Please read carefully before installation and before any
work on or with the regulator.
Page 7
Wherever possible, keep input, output and supply leads and sensor cable physically
separate from each other and do not lay them parallel to each other.
Mains voltage cables and low-voltage cables must not be laid in one cable.
Use screened and twisted interface and sensor cables.
Earth the screening of temperature sensors unilaterally in the switchbox.
Ensure correctly wired potential equalisation.
When selecting wiring materials and installing and connecting the temperature control-
ler to the electricity supply, account must be taken of DIN VDE 0100 “Erection of power
installations with rated voltages below 1000” or the relevant national regulations (e.g.
based on IEC 60364).

4. Technical Data
4.2 Fitting the sensor
When setting the temperature controller parameters (and whenever the sensor is
replaced) the “actual value correction” [Parameter C91] must be adjusted so that the
temperature measured corresponds to that shown on the display. A reference thermo-
meter should be used for this purpose.
Pay attention to the permitted temperture range for sensor cable exposure.
40 mm
The sensor cable must not be chafed or kinked.
There must be no substantial mechanical pressure on the sensor tube.
Do not place the sensor and the high-voltage cable in the same cable
conduit (not even within the switchbox).
Temperature range sensor cable -10°C .. +70°C
Changing the sensor cable length
lf it is necessary to shorten or lengthen the sensor cable on installation (or if a sensor
other than the one supplied is to be fitted), the "actual value correction" parameter
must be adjusted accordingly.

just the agitator runs for the time being.
When the target temperature is reached, the compressor switches off.
At the end of the set “after-stirring” period [c20], the agitator also switches off.
During cooling breaks the agitator switches on periodically, in line with the set
“pause time” [c21] for the “after-stirring” period [c20], in order to ensure an
even temperature throughout the milk.
If the milk temperature rises again, and exceeds the selected target tempera-
ture by the hysteresis value [c10 or c11], the compressor and agitator are
switched on again automatically.
