Contents Appliance description
The WTS-200 is a universal tank control unit combining a modern milk
cooling regulator and a complete cleaning programme control system in
one.
The control unit has various operating modes:
!OFF mode (with continuous stirring function)
The control unit is on stand-by. The display shows 'OFF', the LEDs
are out and all output replays are deactivated.
In the OFF mode the agitator can be switched on and off by press-
ing a button. In parameter [C25] can be set after which time the
agitator switches off automatically.
The following operating modes can only be selected from the OFF
mode. It is not possible to switch directly from one of them to
another.
CAUTION: The control unit is live even when switched off.
!Cooling mode
The current milk temperature, as measured, is permanently
displayed.
It is possible to switch between two freely adjustable target temper-
atures by pressing a button. If the milk temperature exceeds the
selected target temperature (T1 or T2) by the hysteresis value, the
compressor relay and agitator are automatically activated. Once
the target temperature is reached, the compressor switches off,
while the agitator continues to operate for the pre-set 'after-stirring'
time.
During non-cooling periods the agitator switches on at pre-set
intervals in order to ensure an even temperature throughout the
milk.
Independently of this a short or long 'intermediate stirring' period
can be selected during cooling by pressing a button.
Start cooling mode by pressing button on foil keyboard:
If the delayed start is activated (parameter [P62]), cooling starts for
the first milking after a delay. If the cooling button is pressed twice,
cooling starts immediately.
Start cooling mode via digital input:
The cooling starts immediately - depending on the setting in
parameter [C79] - or with a delayed start cooling.
!cleaning mode
The cleaning timer controls water intake as either by time or level,
selected. All running times (heater, pump, detergent injection) can
be set separately. Detergent switchover from alkaline to acidic can
also be set.
The WTS-200 controls the various processes and times needed
for a thorough wash fully automatically.
Following a power failure the control unit restarts in the mode
in which it was operating before the outage.

Safety
The universal tank control type WTS-200 is used to control heating and
cooling systerns, alarm devices, fans, etc.
Any other use of the device is permitted only with prior written permissi-
on from the manufacturer.
The universal tank control is ready for use once the parameters have
been set. lt should not be used before this has been done as this might
result in damage to the plant and the item to be cooled or heated.
The device is fitted with a resistance temperature sensor.
The device must not be installed in potentially explosive
atmospheres.
The universal tank control type WTS-200 fulfils the EC requi-
rements for electromagnetic compatibility (EMC) and the Low
Voltage Directive (LVD).
The safety components meet the VDE regulations.
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.
The universal tank control must be installed by an authori-
sed specialist observing local safety regulations.
Access to the environment when connected must be
restricted to specialised personnel.
The universal tank control contains live components and
must not be opened up.
lt must not be used if the housing or connection terminals
are damaged.
No fluids must penetrate the housing.
The universal tank control may not be exported to the USA
without the manufacturer's express permission.

It is essential not to install the device under the following conditions:
"severe jolting or vibration
"permanent contact with water
"relative humidity of more than 90%
"sharply fluctuating temperatures (condensation)
"operation in an aggressive atmosphere (ammonia or sulphur
fumes) - risk of oxidation
"operation in the immediate vicinity of radio transmitters with high
levels of spurious radiation.
Installation of housing
For fixing the housing please follow the instructions:
!Place the seal carefully in the groove. Ensure it is not twisted.
!Insert the housing from the front through the switchboard cut-out
and fasten using the screws provided.
!Carry out the electrical wiring and sensor connection in accordance
with the following description.
Fitting the sensor
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. See the
section "Setting the actual value correction" on page 38.

Installation
Before connecting ensure that the mains voltage is the
same as indicated on the device's type plate.
Incorrect electrical connection can cause damage to the
tank control and to the equipment.
The mains voltage should not be switched on until all
components including the sensor are connected.
No appliances with current levels in excess of the maxi-
mum values indicated on the relays should be connected
to the relay contacts
Use contactors.
Downstream contactors must be fitted with an RC protecti-
on circuit. (see also page 41).

Cleaning with alkaline or acid detergent
If main rinse 2 is activated, both alkaline detergent in the main rinse 1
and acid detergent in the main rinse 2 are used for each cleaning cycle.
If main wash 2 is deactivated, it is possible to programme the cleaning
sequence so that
- always alkaline detergents or
- alkaline and acid detergent in alternation
are dosed in main rinse 1.
The setting is made in parameter [r21]. Here is also set after how many
alkaline cleaning cycles an acid cleaning cycle shall take place automat-
ically.
If a changing detergent was parameterized, the display shows the cur-
rent detergent during the dosing process.
