|
|
|
|
Excellent cooling tank control with the most comprehensive functions for the cooling and
cleaning operation - additionally with integrated tank monitor (according to the legal
regulations and requirements of leading
dairies).
The WTS-300 offers everything your cooling tank needs!!
The controller includes:
- The integrated milk temperature control with automatic after-stirring control controls the cooling compressors or ice water pumps and agitator motors in the milk cooling tanks.
|
- The integrated cleaning control offers extensive possibilities for your device for an optimum tank cleaning. When exchanged it replaces completely the old mechanical switch boxes.
|
- The integrated tank monitor complies with the legal regulations of the leading dairies.
|
- Via the integrated milking robot-interface a connected robot (if available) can be directly controlled, without any additional external components.
|
|
|
|
|
The WTS-300 is also available pre-assembled in a solid switch box (IP65) for a wall mounting.
Required contactors for the rinsing pump and the heating are already integrated and completely wired.
The customers can directly connect the device on terminals.
Depending on the design, the required additional modules for the tank monitor function are
already integrated. |
|
|
|
The configuration software WELBA "CONSOFT" is included in the delivery for convenient programming of the controller and later data evaluation.
The software offers the following functions:
- Simple and convenient parameter setting
- Processing and display of tank monitor data
- Display and printing of data in tabular or graphic form
- Storage of tank monitor data (also in CSV format)
- Software update for adding new functions (future-proof)
- REMOTE CONTRL via the Internet or optional remote maintenance modem
- Alarm notification by EMAIL or SMS

Remote maintenance
The remote maintenance of the WTS-300 is basically possible with three options:
- Via the Welba EMAIL- alarm and remote maintenance modem ESIPM-001 *
Remote maintenance is carried out via internet transmission.
- Via the Welba SMS- alarm and remote maintenance modem ESGSM-001 *
Remote maintenance is carried out via wireless transmission.
For the use a standard mobile phone card (SIM-card) with data volume is required.
- A possibly existing PC with installed Teamviewer-Software (e.g. from the robot control) is permanently connected to the WTS-300 via a USB adapter cable *.
|
|
EMAIL- or SMS-alarm
For the EMAIL- or SMS-alarm the corresponding Welba alarm and remote maintenance modem is required. In the event of a fault, alarms can be automatically sent to different phone numbers or email addresses. |
|
SMS status query
With the SMS modem ESGSM-001*, an SMS status query is also possible, with which the current status of the tank can be queried at any time and from any location. (With the EMAIL modem, this would be possible via remote maintenance.)
* see optional accessories |
|
|
Additional components may be required for the full range of functions of the tank control.
- USB adapter cable
- Alarm and remote maintenance modules
- Agitator monitoring module
- I/O expansion modules
