Operating Manual for SBR small wastewater treatment systemsKLbasic controlKLplus control The vacation mode can be set for amaximum of 90 days.By pressingonce, you can return to themaintenance level. Pressing this key again,you can return to the automatic mode. Note: If no key has been pressed for two minutes, the normal mode is automatically set withoutsaving the date that has been just entered.5.2.5. Reading out errors – reading out old faultsThe control saves fault messages and the operation of the valves using the function “Manual mode“in the so-called logbook. By means of this function, the past fault messages can be called with theirrespective dates and times. The individual messages can be called using the arrow keys. You canexit this menu item by pressing the “Esc“ key. Note: Up to 128 fault messages can be saved. If this number has been reached, the oldestmessage is always deleted for each new message. The memory can be deleted by skilledmaintenance personnel in the service menu using the command “Emptying the logbook“.5.2.6. Displaying the settingsWith this menu item, the current settings of the control can be displayed. Changing these settings isnot possible. This menu item is used for analysing the setting without making changes.5.2.7. Service menu and action codeIn the service menu, the operational parameters can be changed. The access to these parameters isprotected by a code. The operational parameters can also be changed by means of a specific actioncode. This second maintenance level may only be accessed by qualified specialist personnel! In the event of unauthorised interference with the control settings, thewarranty claim expires!5.3. Replacing fusesBefore replacing the fuses, the plant must be switched off by means of the red main switch!In order to replace or check fuses, the control and machine cabinet must be opened with the keysupplied.The micro-fuses described above are on the rear of the control.Used fuses:Micro-fuseSupply line F1Consumer F2230 V / 50 Hz8 A, medium time lag2 A, time lagIn order to replace the micro-fuses, please proceed as follows:– Turn the head of the holder by applying slight pressure and using a slot screwdriverSL 1.0 x 5.5 for a quarter turn to the left (anti-clockwise).20KLARO GmbH
Operating Manual for SBR small wastewater treatment systems– Remove the head of the holder with the fuse.– Replace the fuse.– Insert the head with the fuse into the opening of the holder.– Gently press on the head of the holder using a screwdriver and fix the fuse by turning the headfor a quarter turn to the right (clockwise). Note:If you are not able to solve the problem, please contact your maintenance company or KLARO as soonas possible.5.4. Functional principle of the power outage detection deviceThe control is equipped with a power outage detection device that is powered by an integratedemergency power supply (buffering). In the delivery state, the emergency power supply is empty. It ischarged after the control has been switched on. In the event of a blackout, the charge of an emergencypower supply is sufficient for signalising the power outage for approx. 12 hours. If the emergency powersupply is not used to compensate power outages, the discharge of the emergency power supply isprevented from being discharged by means of a circuit.Important: In the event of a power outage, the setting of the time / date is supplied with power by meansof an additional buffering for a period of approx. 10 days. All saved data such as operating hours,programme settings etc. are preserved. If, however, date and time have not been set, weekly operatinghours of the aggregates are no longer saved. Future error messages are then saved with an incorrectdate.If the plant is disconnected from the mains (e.g. due to a blackout, when the internal fuse is blown orwhen separated from the wall socket), the detection device sends alternately an acoustic and visualsignal regardless of the actual cause. The device reacts to a power outage with a delay of five seconds.This prevents that short outages that often occur, for instance, during a thunderstorm, but do not impairthe overall function of the wastewater treatment plant, are unnecessarily signalled.- The five-second delay is followed by an intermittent with a read flashing signal. At intervals offive seconds, five flashing signals are continually sent with a beep for a period of approx.12 hours (with a completely charged emergency power supply).- Switching off the device is not possible in this state.When the mains voltage returns, the device is reset to the monitoring state without any further keys beingpressed and the control continues to run from the point at which it was interrupted. The fault messagedisappears automatically. When the emergency power supply is discharged, the operation of the plant isrestarted with a cycle pause.Blackout Attention: If the plant has been disconnected from the mains for more than 24 hours, thepurification of the existing wastewater is not possible or only possible to a very restrictedextent. Never switch off the plant (except for maintenance of plant components andfunction-restricting faults of the plant)KLARO GmbH 21
