Furthermore current is cut in half in each of parallel connected single battery All servos directly connected to a DPSI RV are supplied with full power and each servo obtains maximum current without burden the damageable receiver Due to switching the supply voltage electronically the switch transmitter does not switch on the current but only supplies a switch on signal there is no power loss weak contacts or transition resistance For all DPSI RV systems the electronically switches are built separately i e the electronically parts are doubled The switches are failsafe and are driven by self holding circuitry rather by a micro controller Thus an operating DPSI RV stays powered on even if the on off switch transmitter is removed or broken or if the microcontroller is malfunctioning Using DPSI RV systems RC receiver sets reach new dimensions In particular a stabilized output voltage which supplies the receiver as well as all servos accounts for A DPSI RV therefore offers Battery switching function Complete voltage regulation for all RC components Electronically failsafe switches Current distribution with HF filtering Battery voltage monitoring with acoustically warnings O0000 page 6 of 44 DPSI RV Family Operating Instructions Version 2 1 Voltage Regulation Until now the receiver set was supplied directly by the connected battery or a corresponding battery switch The output voltage depends heav

4. Version 2 1 6 12 EMCOTEC Filter Capacitor Using powerful digital servos can cause these to induce extremely high peak voltages counter electro automotive force which under certain circumstances damage the receiver or crash the microcontroller in the receiver Because of their dimensions filter capacitors built into the receivers often do not suffice to eliminate these disturbances DPSI systems are equipped with up to 46 filter capacitors and additional parts to suppress or at least lower servo counter electro automotive force Nevertheless it is reasonable to additionally install the EMCOTEC filter capacitor especially when using high power digital servos The EMCOTEC filter capacitor is installed at an unused servo output or at Batt directly at the receiver and makes sure that peak voltages that can disturb the receiver are eliminated Even short voltage dropouts will be effectively bypassed by this capacitor In any case the filter capacitor is a reasonable extension which increases safety in the receiving system with or without a battery switch pO page 35 of 44 DPSI RV Family Operating Instructions Version 2 1 7 Operation To switch on the DPSI RV the 2 mm 0 08 pin plug is pulled from the disconnect socket black and plugged into the turn on socket red The red ultra light LED in the switch and on the circuit board of the DPSI RV not DPSI 2001 RV light up This signals operation Immedia

10. Error Indications DPSI systems use an internal microcontroller that constantly monitors all voltages An intelligent algorithm ensures that low voltage of the connected batteries is detected not only by the short term drop in voltage during movement of all servos The internal resistance of the battery cells which is indeed different for different types of batteries thus has relatively little influence The algorithm was especially designed for operation in RC model airplanes thus a cyclical load of the batteries i e not for permanent load of the batteries Safe detection of low voltage is therefore possible The internal piezo buzzer indicates various types of errors 1 Overload short circuit Error signal Continuous beep If the power consumption of the DPSI becomes too high a continuous buzz tone is emitted In this case there is an external short circuit which can lead to destruction of the DPSI depending on the duration of the short circuit In this case turn it off immediately or remove the batteries This type of error has the highest priority Once the short circuit during operation has been corrected the buzzer stops buzzing after a de qualification time of about 4 seconds 2 Batteries empty Error signal continuous 0 1 second beep 0 1 second pause If the voltage at the receiver or at the servos drops below a value of about 4 3 volts this error will be emitted In this case the batteries rega
