Rotate and press it in to select displays and run switch functions. 3.1 Switching on and off the 12V supply for the leisure area The 12V leisure area supply is connected via the encoder. Switching on and off Exceptions here are consumers requiring constant power when the motorhome or caravan is being used. Just which consumers these are depends on the combination used (LT 50/power supply) -also refer to the operating manual for the EBL ... and CSV ...): F LT 50 with CSV 410-2 (caravans) F LT 50 with EBL 208 (motorhome) F LT 50 with EBL 226 (motorhome) Briefly press the encoder. F F The ”12V ON” symbol illuminates -- the 12V supply to the leisure area is on. If the LT 50 control panel does not respond, either shutdown is active (for EBL 208 and CSV 410-2; see section 3.4 for how to cancel it) or the battery is discharged (fully charge the battery if required). If the ”12V ON” and ”Leisure battery” symbols flash 3 times, shutdown is active (see section 3.4 for how to cancel it). The ”12V ON” symbol goes out -- the 12V supply to the leisure area is switched off. Switching off is only possible when the ”12V ON” symbol is on. 831.014 BA / EN Date: 12.03.2014 3 Instruction Manual for LT 50 Control Panel 3.2 12V supply to the different consumers -- switching on and off Power to the following consumers can be switched on and off individually: Water pump Tank heater The 12V supply for the leisure area must be switched on for these functions (see section 3.1). F F The LT 50 switches to idle mode about 10 seconds after an operation. Lighting up of the relevant symbol or LED then indicates the switch states. Water pump Turn the encoder until the fill level of the water tank is displayed on the LED scale. The current switch state is shown by the ”Water tap” symbol. Press the encoder. F F The switch state changes (symbol lights or goes out): The 12V supply to the water pump is switched on/off. Tank heater, waste water tank Turn the encoder until the fill level of the waste water tank is displayed on the LED scale. The red LED above the ”Waste water tank” symbol shows the current switch state. Press the encoder. F F The switch state changes (LED lights or goes out): The tank heater is switched on or off. When the 12V supply to the leisure area is switched off, the power supply for the water pump is also switched off. The switch state of the ”Waste water tank heater” remains unchanged (the red LED goes out when the 12V supply is disabled but the tank heater may remain on). 4 Date: 12.03.2014 831.014 BA / EN Instruction Manual for LT 50 Control Panel 3.3 3.3.1 Displays Mains indicator The ”Mains indicator” symbol lights up when 230V mains voltage is being applied to the 12V charging system. The batteries are charged. The display is only shown when the 12V supply for the leisure area is switched on (”12V ON”). 3.3.2 Battery voltages The 12V supply for the leisure area must be switched on for the display (see section 3.1). Turn the encoder until the ”Leisure battery” symbol lights up. F F The ”Volt” scale lettering lights up. The voltage of the leisure battery is displayed on the LED scale for approx. 20 seconds. The following display function only exists for motorhomes because caravans have no vehicle battery. Turn the encoder until the ”Starter battery” symbol lights up. F F The ”Volt” scale lettering lights up. The voltage of the starter battery is displayed on the LED scale for approx. 20 seconds. CAUTION! Batteries (regardless of type) can be damaged permanently, possibly beyond repair, when fully discharged. So therefore: F Avoid low battery charge (indicated by low voltage) F Check the voltage regularly (see section 3.3.2) It is best to carry out checks in the morning before 12V consumers are switched on. The following table shows how to correctly interpret the leisure battery voltage. Batteryvoltage Up to 11V Risk of total discharge (see above) 11.5V to 13.2V 13.2V and over 1) If 831.014 BA / EN Battery operation Mobile operation Mains operation Vehicle stationary, no 230V connection Vehicle moving Vehicle stationary, 230V connection When consumers are switched off: battery flat The alternator is not charging the battery The EBL ... electroblock is not charging the battery When many consumers are switched on: possible battery overload 12V vehicle power supply overloaded 12V vehicle power supply overloaded Normal range 1.

No charging by the EBL ... electroblock 1) 2. 12V vehicle power supply overloaded 1) 2. 12V vehicle power supply overloaded 1) Battery is charged Battery is charged Only occurs briefly after charging the voltage does not exceed this range for several hours. Date: 12.03.2014 5 Instruction Manual for LT 50 Control Panel The values specified above apply for running operation, not for the off-load voltage (see below). Off-load voltage Apart from displaying the battery capacity (see section 3.3.2), measuring the off-load voltage is a simple and effective method of checking the condition of the battery. Off-load voltage is understood to be the voltage of the charged battery in a passive state, with no current being supplied or drawn. Take the measurement several hours after the last charging. No significant load should have been placed on the battery in the interim period, meaning no current should have been drawn from it. If the off-load voltage of the battery is less than 12.0V, there is a risk of total discharge. The following table shows the correct interpretation of the off-load voltage displayed. The values specified apply for Gel batteries. 3.3.3 Values for off-load voltage Charge state of the battery Less than 12V Totally discharged 12.2V Approx. 25% 12.3V Approx. 50% More than 12.8V Full Tank fill levels The 12V supply for the leisure area must be switched on for the display (see section 3.1). Turn the encoder until the ”Water Tank” symbol lights up. F F F The ”%” scale lettering lights up. The ”Water Tank” symbol lights up (or flashes). The fill level of the water tank is displayed on the LED scale for approx. 20 seconds. Turn the encoder until the ”Waste Water Tank” symbol lights up. F F F The ”%” scale lettering lights up. The ”Waste Water Tank” symbol lights up (or flashes). The fill level of the waste water tank is displayed on the LED scale for approx. 20 seconds. If the relevant symbol flashes when the fill level of a tank is being displayed, the water tank is empty (or the waste water tank full). If the LEDs flash, there is a sensor fault on the relevant tank (see section 4.1). 6 Date: 12.03.2014 831.014 BA / EN Instruction Manual for LT 50 Control Panel 3.4 Closing down A shutdown is understood to be the isolation of the 12V charging system and all consumers from the batteries. Exceptions: Devices charging the leisure battery continue to be connected (such as a solar regulator) The LT 50 control panel is operated at different supply devices. These are the following depending on vehicle model (motorhome or caravan): F For caravans: -- CSV 410-2 caravan power supply F For motorhomes: -- EBL 208 electroblock -- EBL 226 electroblock Shutdown and re-enable as follows: F Vehicle Caravan Motorhome Motorhome Operation on CSV 410-2 EBL 208 EBL 226 LT 50 -- -- Disable 12V supply Press and keep pressed the encoder F Symbols ”Leisure battery” and ”12V ON” flash three times after about 10 seconds F Shutdown performed Cancelling the shutdown: Press and keep pressed the encoder F Symbols ”Leisure battery” and ”12V ON” flash three times after about 5 seconds F Shutdown cancelled F 12V supply enabled Release the encoder Move the ”Battery” battery isolator on the EBL 208 to the ”OFF” position F Shutdown performed Cancelling the shutdown: Move the ”Battery” battery isolator on the EBL 208 to the ”ON” position F Shutdown cancelled -- At the relevant -power supply unit CSV ... / EBL ...
