![]() (e.g.: If position 2 – manual reset – is selected, the LED will blink twice. 1.2 1.6 V higher than the adjusted interrupting. If the user presses the button twice, the manual reset is selected.Īpproximately 4 seconds after the last time the button is pressed, the LED will blink to show the programmed reset function. 20 - 23.2 V with 24 V (acoustic signal before switching off, may be deactivated). Please unmount Eve Thermo, make sure the valve pin can be pushed in freely, and re-mount Eve Thermo firmly. When the button is pressed once now, the automatic reset function is selected. Eve Thermo is active at the displayed target temperature. At this point the button must be released. This indicates that the BDB-250 is in programming mode. This is done by pressing the programming button and holding it down until the LED flashes. The user can choose if the BDB-250 is reset manually of automatically. The manner in which this is done can be found under “Programming” The manner in which the BDB-250 will be reset is programmable by the user. If an external switch is connected to the remote input, this can also be used to reset it manually. This is done by pressing the build-in switch. However, when the manual reset function has been programmed, the user has to reset the BDB-250 by hand. If the user has chosen the automatic reset function, the relay of the BDB-250 will be activated directly after a “correct” voltage has been measured. When the BDB-250 is switched off and the voltage returns between 11.0V and 14.0V, there are two ways to re-activated it. This will continue for 90 seconds after which the relay will be opened and the LED will turn off. If the input voltage drops below 10.0V, the LED will blink to indicate an under-voltage situation. When the voltage rises above 15.4V, the entire “warning” process will be skipped and the relay will switch off immediately. This will continue for 90 seconds after which the relay will be opened and the LED will turn off. Battery Guard also offers the vehicle operator the ability to manually isolate the batteries via the Battery Guard reset switch. If the input voltage rises above 15.0V, the LED will start blinking to indicate a detected overvoltage. Leave the device connected to power to give the battery time to charge. If these conditions are not met, the relay will open. After this, if the input voltage is above 10.0V below and 15.4V, the relay will close. This means that after connecting the BDB-250, the first thing it does is wait a second before doing anything else. ![]() The system now allows the driver 4 minutes to start the vehicle before the battery disconnects again.SUPER B SB-BDB-250 is an external under and overvoltage protector, to secure super B tractions batteries against under- and overvoltage with the lowest possible stand-by current.īefore the BDB-250 becomes operational, it has to determine if a 12V or a 24V system is connected. PHONE (972) 393-1700 FAX (972) 393-1701 Welcome to the growing circle of MasterGuard protected families. To reconnect the battery, the driver needs to press the momentary switch. MasterGuard (COVER ART) PHOTOGRAPH OF ALARM Heat Activated Fire Alarm Model QR-50 Owner’s Manual. When the battery is disconnected, a LED indicator on the dash mounted switch blinks to let the driver know that the system has disconnected the battery. ![]() This feature prevents a shutdown in the event of a charging system failure while driving. If the ignition switch is turned on, the system will not disconnect the battery under any circumstances. When the voltage drops below 12.1 / 24.1 volts for approximately 4 minutes and the ignition is off, Battery Guard 2000 will automatically disconnect the battery from the vehicle’s electrical system. This may happen if a light or an other accessory is left on for long periods of time.īattery Guard 2000 constantly monitors the voltage level on the battery to determine the level of charge. The operator can also manually disconnect the battery by pressing and holding the reset switch for 3 seconds. NO MORE FLAT BATTERIES WITH BATTERY GUARD 2000!īattery Guard system is intended to be used in vehicles to prevent the battery from inadvertently being discharged by some unwanted load. By removing all loads connected to it, the Battery Guard 2000 prevents any additional power consumption, allowing enough battery charge to start the engine.
