- Page 2 Dear customer, We are delighted that you have decided to purchase the PowerBox Cockpit / Competition SRS from our range. We hope you have many hours of pleasure and great success with your new PowerBox. 1. Product description The PowerBox Competition SRS and Cockpit SRS incorporate SRS technology, and since their introduction in 2010 they have gained wide acceptance as the current state of technology.

- Page 5 3. First steps, the unit in use: In the following instructions we do not differentiate between the PowerBox Cockpit SRS and Competition SRS, since the method of programming the two units is absolutely identical. The only difference is that the PowerBox Cockpit SRS includes the door sequencer function, whereas the PowerBox Competition SRS does not.
- Page 6 Your PowerBox stores the last switched state (on or off). That means: if the backer is switched off using the SensorSwitch, it stays switched off. Once switched on, the backer can only be turned off again using the switch unit. Intermittent contacts or interruptions in the power supply cannot cause the backer to be switched off.
- Page 7 PowerBox. This by no means indicates a fault in the PowerBox; in fact it proves that the system features genuine redundancy. Here at PowerBox Systems we take great trouble to compensate for manu- facturing tolerances between the two regulators, but it is never possible to produce a system which is completely devoid of tolerances.
- Page 8 3.5. Basic settings The PowerBox Cockpit / Competition SRS feature a new kind of graphic OLED screen, intended to do away with old-fashioned programming methods based on flashing LED codes, morse code beeps or obsolete mechanical jumpers. The screen provides the basis for an extremely user-friendly control system, and eliminates the need for a supplementary setup unit or programming device.
- Page 9 - Switch both batteries on. - Press the SET button and hold it pressed in until the following display appears: - Press button II until the cursor (hollow circular ring) lines up with Power Manager, then press the SET button. The following display now appears: If you wish to change one of the settings, use buttons I and II to move the cursor to the appropriate menu point, then press the SET button to...
- Page 10 Key to the individual menu points: - Chemistry: this is where you set the battery type. Three different types of battery are available: • Two-cell LiPo • Five-cell NiMH • Two-cell LiFe - Capacity: you can enter the nominal capacity of your batteries at this point. - Output voltage: you can select the output voltage to 7.4V or 5.9V CAUTION: if you intend to select the 7.4V output voltage, please ensure...
- Page 11 3.7. Setting the receiver system Caution: Please ensure that you have set the correct receiver type before connecting the receivers. This is important, because the Spektrum system operates on only 3.3V, whereas all other receivers work on 5.9V or 7.4V. For example, if you set the receiver system to Futaba and connect a Spektrum Remote Receiver, the Spektrum Remote Receivers will be ruined! If this setting is not selected, the subsequent functions, settings and...
- Page 12 The following systems are connected to inputs RX1 and RX4 using the three-core patch-leads supplied in the set: • Futaba S-BUS: Set the receiver or receivers to “Normal Mode” - not “High-Speed Mode”. If you are using the R7008SB receiver it is particularly important to set Output 8 to S-Bus, and to use this output.
- Page 13 • Jeti Duplex EX: The digital signal employed by Jeti is substantially faster and more accurate than a PPM signal. The R-SAT2 satellites must be loaded with software version 3.11 or later in order to be able to switch the EX signal on.
- Page 14 3.8. Output Mapping The OUTPUT MAPPING function allows the channels to be assigned in any sequence you like. This makes it possible to connect the servos to the sockets which best match the wiring arrangement in your model. The only outputs which have a fixed assignment are those for the door sequencer.
- Page 15 Explanation of FS and HD: • FS: If there is a complete loss of signal at all receivers connected to the system, this output runs to a previously determined position. See Point 3.9. for information on defining this position. • HD: If there is a complete loss of signal at all receivers connected to the system, this output remains in the last known valid position.
- Page 16 4. Servo Match Function The Servo-Match function provides the facility for adjusting the centre position and end-points of the servos connected to the backer. If you have a model aircraft with more than one servo per control surface, this makes it possible to set up multiple servos to move to identical positions at identical times.
- Page 17 The following examples illustrate the correct procedure for the Servo-Match function: a) Fine-tuning multiple servos to operate on a single control surface; in this case the aileron of the right-hand wing. - Disconnect the linkages to the - as yet unmatched - servos, to avoid them being subjected to severe forces during the adjustment procedure.
- Page 18 b) Reversing an output when servos are installed in a “mirror-image” arrangement: in this case left and right landing flaps. - Disconnect the linkage to the left-hand landing flap, to avoid the servo being subjected to severe forces during the adjustment procedure. - Assign the output to the appropriate socket in the OUTPUT MAPPING menu.
- Page 19 5. Setting up the door sequencer Select the SEQUENCER point at the main menu; this takes you to the following screen display: The SETUP ASSISTANT is a new function in the Cockpit SRS which has been included since software version 15; it makes the task of programming the actual door sequencer function considerably easier.
- Page 20 Operate the appropriate transmitter switch, and the PowerBox automatically detects it as the switch which you have assigned to the retract system. The on-screen arrows should now be located in front of UP/DOWN. If you find that your retract switch works in the wrong “sense”...
- Page 21 Mode 3: Extend undercarriage: Open nosewheel doors → extend nosewheel → close nosewheel doors Open main wheel doors → extend main undercarriage → close main wheel doors Retract undercarriage: Open nosewheel doors → retract nosewheel → close nosewheel doors Open main wheel doors → retract main undercarriage → close main wheel doors Move the cursor to the appropriate mode, and press the SET button to confirm your choice.
- Page 22 Press the SET button twice to move to the next screen display: The undercarriage should now retract. If not, hold button I pressed in until the valve is triggered, and the undercarriage retracts. Press the SET button to move on to the next stage of the procedure. Connect the nosewheel door servo to output 1.
- Page 23 Note: if you are only using one valve for all the wheel doors, you can by-pass the last four points by selecting OK. All the settings are now complete, and you will see one final safety query: Move your transmitter switch to the “gear down” position. It will now take a few moments for the Assistant to create the necessary tasks, and move the doors to the correct position without any fouling or jamming.
- Page 24 “jerk” when the legs lock, that can also be simulated. The opening and closing processes can be set up entirely individually and independently of one another. In spite of the vast scope of these facilities, the sequencer is simple and user-friendly to set up, as the screen and menu system guide you through the procedure.
- Page 25 Intelligent programming aid: If you wish to set up multiple tasks in order to move the wheel doors to several positions, it should be obvious that the new task’s initial positional value and start time are determined by the previous position and time for the servo concerned.
- Page 26 DOWN » UP means undercarriage retraction. In this example, when the switch operated, servo immediately starts running slowly from the left to the right servo end-point (Start time 0.0 s). The positional values vary according to your linkages, and must be adjusted to suit your individual model.
- Page 27 6. Channel lock when undercarriage is retracted The PowerBox Cockpit SRS’s door sequencer also features one last unique function: it is now possible to switch a channel off when the undercarriage is retracted. The purpose of this feature is to prevent the retracted nosewheel moving inside the fuselage when the pilot gives a rudder command, as this may cause the mechanical system to jam.
- Page 28 8. Frame rate: What does ‘frame rate’ mean? This value indicates the time interval at which the servo signal is refreshed. Modern digital servos are unlikely to encounter problems with the 12 ms setting, but older analogue servos may require a longer setting of 21 ms.
- Page 29 - HoTT Connect the backer’s telemetry output to the receiver’s Sensor input using a standard commercial Uni patch-lead. Select the “Electric Air Module” in your transmitter’s telemetry menu. The voltage of both batteries, and the residual capacity of the weaker battery, can now be viewed on the transmitter’s screen.
- Page 30 11. Regulator error message The PowerBox Cockpit/Competition SRS constantly checks both vol- tage regulators independently of each other. If a fault should occur in one of these regulators, this warning will appear on the screen: There are three possible causes for this warning: - One or both regulators is generating insufficient output voltage or none at all.
