Structural components 6.1 Coffee grinder The service life of the grinding wheels is approx. 80.000 grinding processes (1 grinding process = approx. 10 g). The grinding capacity on the finest setting is approx. 180 g/min, i.e. roughly 3 g/s. The grinding capacity decreases as the wheels begin to wear down. The grinding process is timer-controlled, which means that less ground coffee is dispensed as the grinding wheels begin to wear down. The reduced grinding capacity can be compensated by increasing the grinder running time (parameter: ground coffee quantity). If the grinding capacity is severely reduced, the grinding wheels must be replaced. 6.1.1 Adjusting the grinding fineness . Set the ground coffee quantity and grinder running time to the standard value. Disconnect the machine from the mains! Adjusting the grinding wheels Adjusting ring Catch . Release the catch. . Tighten the adjusting ring until the upper grinding wheel touches the lower grinding wheel. . Turn the adjusting ring back a notch. Upper (fixed) grinding wheel Cap nut Lower (rotating) grinding wheel . Grasp the cap nut and turn the lower grinding wheel manually through at least 1 complete revolution. There should no longer be any rubbing sounds: otherwise, turn back another notch. Then perform the following setting for the coffee type. Settings for coffee type After adjusting the grinding wheels: - Instant coffee = turn back approx. 12 notches - Cafe Crème = turn back approx. 10 notches, - Espresso = turn back approx. 10 notches. . Carry out test run. . If necessary, correct the setting on the coffee grinder: loosening the adjusting ring (i.e. turning anti-clockwise) causes the beans to be ground more coarsely (please note that the ground coffee quantity increases accordingly). Service instructions bremer VIVA, issued 1997-07 Status: 2003-03 6-1 6.1.2 Weighing the ground coffee Weighing without dismounting the housing Please note that slight deviations are possible due to ground coffee remnants in the brewing unit. . Place a sheet of paper or filter bag in the grounds container. . Press the desired article key. Grinding takes place and ground coffee is metered into the brewing cylinder. . Switch the machine off and on again: - after the grinding process, - immediately after opening the brewing valve. The brewing unit moves upwards and scrapes the ground coffee powder into the grounds container. . Take out the grounds container and weigh the ground coffee powder. 6.1.3 Removing the coffee grinder Transport locking device (on base) Holder for inserting in housing . Remove the plug. .

This involves measuring the upper and lower limit positions of the plunger, then calculating and storing the distance between the two. Go to photoelectric barrier for reference point Procedure: Upper brewing plunger with needle filter 2. Brewing plunger moves all the way down to record the bottom limit position. At the same time, the distance covered is recorded via the perforated disc and encoder. Ground coffee funnel with wiper Brewing bush Lower brewing plunger with strainer 1. Brewing plunger moves upwards to determine the upper limit position (reference point) and is wiped at the same time. 3. Brewing plunger moves upwards then back to the home position (ready for brewing; ground coffee funnel in filling position). Using the stored data, the control system is now able to move the ”upper brewing plunger” to each desired/programmed position: e. g. to the positions ”Fill with ground coffee”, ”Brew coffee”, ”Compress ground coffee” or ”Wipe off coffee grounds”. Service instructions bremer VIVA, issued 1997-07 Status: 2003-03 6-5 Brewing sequence After having pressed the product key: 1. Coffee is ground and falls into the brewing cylinder. 2. ”Upper brewing plunger” moves down until it is a set distance away from the ”lower brewing plunger” depending on the required article. The machine checks whether the metered quantity of ground coffee is sufficient by attempting to recompress it with the ”upper brewing plunger” at reduced motor power( ”bean container empty” signal). The grinder of the assigned product keys gets blocked. After refilling the bean container and deleating the blocked product keys by pressing one of them more than 5 seconds they are again usable. The next 2 products after deblocking are not checked if there is enough coffee dispensed. 3. Brewing water is metered. 4. ”Upper brewing plunger” recompresses the ground coffee in order to to dry it. 5. ”Upper brewing plunger” and ”lower brewing plunger” move upwards, thus automatically actuating the wiper. The coffee grounds are scraped off into the grounds container. 6. Brewing plunger moves to the home (i.e. filling) position.

For preparing hot water for all types of coffee. - Brewing pressure for coffee approx. 0.4 - 0.6 bar: the pressure for the brewing water is reduced via the nozzle (1.2 mm dia.) in the flow sensor. - Brewing pressure for coffee types espresso, schümli and cappuccino approx. 8 bar. The pressure for the brewing water is increased via the motor-driven pump. 2. For dispensing hot water in machines without a hot water/steam boiler. In these models, it is not possible to brew and dispense hot water at the same time (interlocked functions). The water is supplied to the brewing water boiler - from the pressure regulator, - by the motor-driven pump M1, - via the flow sensor B4, - via the check valve. The boiler pressure in the operational state is 2.6 - 10 bar. When hot water is dispensed from the brewing water boiler, more cold water is automatically supplied. The temperature is controlled via the NTC temperature sensor B1. Filling the brewing water boiler After opening the on-site water valve: - Cold water flows into the brewing water boiler until a pressure of 2.6 bar is built up. A previously empty brewing boiler (initial filling) is now filled with water to approx. 2/3 of its capacity. After switching on the machine: - The control system checks whether the flow meter is emitting impulses. - If the flow meter is no longer emitting impulses, the brewing unit moves to the brewing position. - The brewing valve opens and remains open until the flow meter has measured a suitable number of impulses (predetermined by the control system). During this time, any air present in the brewing water boiler escapes. The supplied quantity of water is sufficient to fill the boiler completely (including initial filling). Any excess water flows out of the coffee dispenser. - The heater of the brewing water boiler is switched on and heats the water to brewing temperature. From 80°C upwards, the article keys are released for coffee-making.

For dispensing steam and hot water. 2. For frothing or heating up milk. The water is supplied to the hot water/steam boiler - from the pressure regulator, - via the check valve, - via solenoid valve Y2. The boiler pressure in the operational state is approx.1.3 bar. The water level in the hot water/steam boiler is controlled by the electrode. The NTC temperature sensor B2 enables hot water, steam and milk products to be dispensed from a temperature of 110°C upwards. The temperature is regulated via the pressure switch. Filling and heating process of hot water / steam boiler When the machine is switched on, the boiler heating is deactivated until the electrode is moistened with water for the first time (automatic filling during initial startup). If the electrode is not moistened with water within 200 seconds, the control system switches off the hot water/steam boiler and locks the corresponding article keys. In standby mode, the error code 02 is displayed. If the machine is switched on again, the boiler filling procedure is repeated. Once the electrode is moistened with water, the heater switches on. The solenoid valves for hot water and steam dispensing are open, and close when a temperature of 85°C is detected by the NTC temperature sensor. Limit values for hot water / steam boiler cut-off - For first filling: If the electrode is not wetted with water within 200 seconds. - For first filling: If the releasing temperature of 110°C is not reached within 7 minutes. - During operation, after having taken hot water: If the electrode is not wetted with water within 240 seconds.

Ventilation for cold pressure: - The magnetic valve Y5 is opened for a period of 0.5 seconds if temperature has fallen below the releasing temperature of 110°C and temperature has not gone up for a period of one minute. Topping up with cold water during dispenser of hot water Topping up with cold water during dispensing of hot water (to avoid excessive splashing): when the hot water dispensing solenoid valve Y4 opens, the level in the hot water/steam boiler falls. The cold water supply solenoid valve Y2 then opens, allowing cold water to flow into the boiler and, at the same time, via a nozzle to the hot water dispenser.

The milk frother for producing hot milk or milk froth is integrated in the dispenser block. The dispensed quantities of coffee and milk/milk froth are divided in the dispenser rocker, thus allowing 2 cups to be filled simultaneously. The coffee dispenser is locked when the dispenser block is pulled out. The pin on the dispenser block actuates the microswitch on the holder guide. Production of milk froth The steam solenoid valve Y5 opens, allowing steam to flow through the dispenser block while milk is simultanously sucked in (injector principle). Via the air nozzle air passes through the pressure equalising chamber and mingles with the milk and steam to produce milk froth. The milk froth flows into the frothing chamber, settles and then flows out again. Production of hot milk (option) The steam solenoid valve Y5 opens, allowing steam to flow through the dispenser block while milk is simultaneously sucked in (injector principle). Solenoid valve Y7 is switched to prevent the entry of air. After being heated by the steam, the milk flows into the frothing chamber, settles and flows out again.

Functional Description The VIVA au lait has two valves more than the VIVA standard design. The single solenoid valves sit in contrast to the standard design directly on the hot water/steam boiler. The steam valve Y8 is used additionally for the heating up of milk and provides for an optimal expenditure temperature of approx. 71 degree C, for the product milk. The additional steam pipe waives the Injectorprinzip. Thus independent sucking in of the milk is no longer possible. In the milk refrigerator is a pump, which promotes the milk to the expenditure head. The steam valve Y9 is in each case always needed for free blisters of the milk pipe by milk remainders, after the expenditure for product.
