2.2 Intended use
These operating instructions contain important technical and safety in-
formation. Please read carefully before installation and before any work
on or with the regulator!
Universal tank controllers WTS-300 are designed to control heating systems, con-
densing units, alarms, fans, etc. in milk cooling tanks as well as to monitor milk qual-
ity. Furthermore, 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 corresponding to protection class 2 (double or re-
inforced 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 universal tank controller is ready for use only when the parameters have been
set appropriately. Its use before this has been done would have no benefits and
could also damage the equipment or adversely affect the milk to be temperature-
controlled.
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 WTS-300.
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 WTS-300 fulfils the EC requirements for electromagnetic compatibility (EMC)
and the Low Voltage Directive (LVD).
The safety components meet the VDE regulations.
