1. DESCRIPTION.

The UMS-02 controller is a programmable time controller with universal application. Its main purpose is to control external devices in the process of washing milk coolers and milking devices, however it is also used, for example, in cleaning tanks for beer wort, juice tanks, car washes, or juice production equipment. The controller’s casing in the UMS-02H version has an IP52 protection class and is designed for built-in. Controller’s electronics is able to work at temperature up to -10 OC. The controller can work in an automatic cycle, according to one of four factory (default) washing programs (with the possibility of their modification) or a program created by the user. There is also the option of manually activating a vacuum pump or a stirrer.

ATTENTION

1. On the external start button and the hydrostatic input, the 230 V AC signal L should be given.

2. Relay no. 5 has normal open (NO) and normal closed (NC) inputs.

5. OPERATING THE CONTROLLER BY A DIRECT USER.

The controller is characterized by the ease of use by a direct user. Operation is limited to using two or three buttons. The other buttons are inactive for the direct user, thus preventing accidental interfering with the factory (default) settings or made by the installer.

5.1. Launching the controller. After connecting the supply voltage, the controller remains in a state of readiness

to work, which is signaled by four lines illuminated on the display.

ATTENTION

The time indicated by the display does not take into account the time needed to pour water in the hydrostatic cooperation mode.

5.2. Enabling and pausing the program. By pressing the program start button [5] (green button), the previously set or

programmed program is executed.

Page 5 of 13

During the execution of the program, user can pause its execution at any time. This is done by re-pressing the start button (green) [5]. When the program is paused, all active relays are switched off. It is restarted by pressing the [5] button again. The program will be continued from the place where it was paused.

5.3. Disabling the program. If necessary, the program currently executed by the controller can be disabled at any

time. This is done by pressing the stop button [6] (red color). When the [6] button is pressed, the program execution is interrupted and deactivated. The controller goes into the ready state.

ATTENTION

If the program is re-enabled, its implementation will start from the beginning.

5.4. Manual activation of the vacuum pump or the stirrer. If this function is activated, the user can manually switch on and switch off the vacuum

pump or the stirrer operation; the [7] button is used for this purpose. Manual switching is only possible when the controller does not execute the washing program; during the program execution, the switch is inactive. The factory settings or made by the installer determine which output (PP – vacuum pump or PPR - stirrer) can be switched manually.

6. CONTROLLER FUNCTIONS.

The controller is equipped with a number of functions that, together with the possibility to create own program, allows the user to adapt the controller to the individual needs (see 7. PROGRAMMING and 9. SETTING TABLE).

1. Washing programs. The controller has 8 programs. Two programs for washing of milking devices and two programs for washing milk coolers are pre-programmed. Factory programs can be freely modified and removed. The remaining 4 places

in the controller's memory allow creating control programs according to the user’s

individual needs.

2. Function of modification and creating programs. The controller enables independent (by the user) creation of a control program. Each program can concist of a maximum 50 steps (sequences), with a duration of 1 s. to 99 min. each. The programming method is very simple and intuitive and has been described in detail in the instruction, in iconographic form. Factory programs can also be modified according to the needs of the user.

3. Function of protection in the event of a power failure. Loss of power supply interrupts the execution of the activated washing program. When the power supply returns, the program will start from the same spot where it has been stopped. In the settings of this function, one can reduce the time to return to the interrupted work (in the range from 1 h to 9 h).

4. A service function that allows testing the correct operation of the control system. This function allows to go sequentially to the next steps (sequences) of the program without waiting for the duration of a given step to expire. The transition is made by pressing the appropriate button. The controller has protection against accidental

Page 7 of 13

switching in test mode to the next step during actual controller operation – this function is only available to the installer.

5. Function of returning to the factory (default) settings. If an error occurs while setting the controller operation, it is always possible to return to the factory settings.

6. Function of manual switching on and off of the vacuum pump or the stirrer.

7. Program start function. The program is started by manually pressing the button located on the front of the controller or by pressing the external button (if connected). It is also possible to trigger the start of the program in an automatic manner, carried out by an external device, connected to the external button input.

8. Function of pausing the execution of the program during its duration. This function allows to interrupt the program at any time, until it resumes. The resumption occurs exactly in the same place where the program was interrupted. Pausing is done by pressing the button located on the front of the controller or by pressing the external button.

9. Function of disabling the program. The controller is equipped with a button that disables the execution of the program, without the possibility of resuming it at the point of stopping. Re-enabling the program will start the program from the beginning.

10. Function of displaying the time remaining until the end of the program. During the program execution, the controller's display shows the time to complete the entire program. The time indicated by the display does not take into account the time of pouring water when using a hydrostatic.

11. Function of completing the process of pouring water depending on the signal from the hydrostatic.

7. PROGRAMMING.

The controller is factory-programmed for standard operating conditions, for the purpose of controlling the washing of the milk coolers (two programs) and the washing of milking devices (two programs). Nevertheless, in order to ensure correct operation of the controller under specific conditions, appropriate adjustments of the operating parameters can be made, including the selection of the appropriate program. After installing the controller, one can also check the correctness of the operation of the entire washing system in test mode. The controller is protected against accidental entry into the service settings mode, assuming only those available to the installer or service technician. These safeguards include:

− the necessity to press and hold the settings entry button [8] for about 15 sec.,

− the necessity to enter the access code, which is given in the table of settings.

Page 8 of 13

ATTENTION

Please do not provide access code to the direct users.

The procedure for entering the access code, allowing entry into the settings and programming mode is shown below graphically:

7.1. Selection of the parameter to be edited.

In the table of settings all available parameters (functions) are given along with their description and possible values to be set. If you want to change any parameter from the available settings, enter the setting mode, and then select the parameter that will be subject to change. The following is a graphical representation of the change in the factory setting of the washing program. The program no. 1 is preset at the factory.

Page 9 of 13

7.2. Editing the program – parameter EdPr.

The controller comes pre-equipped with 4 washing programs that can be freely edited, depending on needs. The remaining 4 places in the controller’s memory are intended for creating a program by the installer; they are empty (do not contain any steps). Each program can contain up to 50 steps (sequences), lasting from 1 second to 99 minutes. Each step is assigned: a) state of 6 relay outputs – active relay (signaled by red diodes marked with numbers

from 1 to 6) or inactive relay,

b) hydrostatic input status – active (signaled by red diode marked with number 7) or

inactive,

c) the duration of the step.

7.3. Setting the dosing of detergent.

To control the detergent dispenser, please use relay no. 6, which in the factory programs is set as a washing relay (signaling that the washing process takes place) and it is active throughout the entire washing process. In order to set the relay no. 6 as the dosing relay, enter the settings and follow the program editing procedure (see 7.2. Editing the program – parameter EdPr). In this case, relay no. 6 must be deactivated in steps, where there is no dosing of the detergent.

7.4. Return to factory (default) settings.

To return to the factory (default) settings, enter the controller settings. Then use the ▲ and ▼ buttons to select the PdOd parameter, confirm the selection by pressing the S button and change its value from 0 to 1, using the ▲ button. Then confirm the changes by pressing the S button again. After doing this, disconnect the power supply from the controller and switch it on again.

ATTENTION

1. A return to the factory settings removes all settings from the controller's memory

while restoring factory settings. So be careful and consciously use this option.

2. The return to the factory settings takes place only after disconnecting and re-connecting the controller's power supply.

7.5. Test mode.

The test mode function is used for accelerated checking of the correct operation of the entire washing system, controlled by the UMS-02 controller. Working in the test mode consists in the possibility of manually going to the next steps of the program, without waiting for the end of the duration of a given step. In order to set the test mode, enter the settings, select UEL parameter and change its value to 1, and then confirm by pressing the S button. Exit from the settings by pressing the off button (red). The test operation mode of the controller is signaled by flashing the green diode, marked with the letter A. After activating a given program, the transition to its next steps is carried out by pressing the ▲ button. You can also go back to the previous steps by pressing the ▼ button.

In order to exit the test mode, enter the controller settings, select UEL parameter and change its value to 0, then confirm with the S button, and then exit the settings by pressing the off button (red).

ATTENTION

After completing the testing, remember to return to the normal operating mode of the controller. During normal operation, the green diode A does not light up.

8. FACTORY PROGRAMS.

The controller comes pre-equipped with 4 washing programs that can be freely edited, depending on needs. There are 2 programs for washing of milking devices (program no. 1 and no. 2) and 2 programs for washing milk coolers (program no. 3 and no. 4). Below are the tables containing these programs. The remaining 4 places in the memory of the controller are designed to create the program(-s) by the user – they are empty (do not contain any steps).
