Operation

5.1 Function overview

The WTS-300 is a universal tank control unit which combines all the
basic functions in one device:
  - milk cooling control
  - comprehensive cleaning control
  - an extended robot interface
  - 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 or-
ganised parameter levels.

Within the working level the control unit differentiates between various
operating modes:

5.1.1

OFF mode (stand-by)

Shows the current time.

All LEDs are out
(Exceptions: robot, outlet valve and tank monitor LEDs may be lit)

All output relays are deactivated
(Exceptions: robot, outlet valve and tank monitor alarms may be active)

CAUTION: The control unit is live even when switched off!

5.1.2 Cooling mode

(can NOT be started from cleaning 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 automati-
cally. Once the target temperature is attained, the compressor contactor switches
off, while t

he 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.
