Summary of Contents for Airtec CYPRES

  • Page 1 Important information Please read english C Y P R E S User’s Guide...
  • Page 2 Like most skydivers, you probably assume you will always have time to deploy your reserve canopy yourself, and that situations requiring use of an automatic opener always happen to others. We do hope that you will never have such trouble, and that your CYPRES will never have to take action to save your life.

  • Page 4: Function

    The operation is quite simple: Just switch it on in the morning prior to the first jump, then forget about it. It is not necessary to switch it off, because CYPRES will do this itself. The weather is constantly checked by CYPRES over the day by measuring the air pressure twice a minute.

  • Page 5: Components

    CYPRES USER’S GUIDE 1.2 Components CYPRES consists of a microprocessor-based, self-checking processing unit, a control unit through which prejump altitude adjustments are made, and a release unit (EOS). Two release units are used on dual-pin systems. processing unit control unit...

  • Page 6: How Cypres Works

    CYPRES USER’S GUIDE 1.3 How CYPRES works Every time CYPRES is switched on it will calibrate to ground elevation by measuring the air pressure several times in a short period of time and taking the average value as the value for ground level. This is happening during the integrated self-test. CYPRES doesn't stop here.
  • Page 7 The distance which the piston moves in case of an activation is approx. 5 mm. The cutter assembly (EOS) is completely self-contained. In the event of activation, there is nothing released. It was specially developed for CYPRES, and is classified as being non-hazardous.

  • Page 8: Energy Supply

    It consists of two round cells, and does not contain heavy metals. Each battery which has been installed in CYPRES has to be replaced after 2 years at the latest. In case that the rig or CYPRES will be out of use the battery should be removed and disposed of after 2 years to prevent possible damage.

  • Page 9: Operational Safety

    Depending on the type and potential impact of the error, CYPRES can either be switched on again or it will stay in shut-down mode permanently. With certain error codes (see error code list on page 24), it is not possible for the user to reactivate the unit.

  • Page 10: Product Overview

    750 feet above ground level (AGL). In the event of a breakaway below this height CYPRES will operate down to apx 130 feet AGL. Below 130 feet AGL opening is no longer useful. For this reason, CYPRES ceases operation below apx 130 feet AGL.

  • Page 11: Student Cypres

    In the case of rate of descent being equal to that of freefall the opening altitude is at approx. 750 feet, being the same as with Expert CYPRES. However, should the rate of descent be lower than that of freefall but still above the limit of 29mph (e.g. with partially opened canopy), then Student CYPRES activates the EOS when the altitude decreases below 1000 feet above ground level.

  • Page 12: Installation

    Mounting: Assembling the CYPRES into a container with an existing approved set-up. CYPRES can be installed in rigs without adding to pack volume or changing their exterior profile. Both the processing unit and EOS are mounted inside the reserve container, while the control unit is placed either underneath the top flap next to the ripcord pin, or on the front of the harness to allow for easy access.

  • Page 13: Processing Unit

    For installation, the processing unit is placed into a specially bolstered and labeled nylon pocket which is supplied with every CYPRES. Excess cable is stowed in the flat part of the pocket underneath the velcro-adjustable flap. If you have to stow both the thinner EOS cable and thicker cable to the control unit, be sure to place the thicker cable so that it lays on top of the thinner one.

  • Page 14: Release Unit

    Furthermore, the force needed to pull the reserve ripcord pin is reduced. Loops supplied by Airtec are pre-treated on the first 2". release unit (EOS) The release elements have to be mounted like described in the CYPRES Rigger’s Guide for Installation. NOTE: WHEN CYPRES IS INSTALLED ONLY USE RESERVE CLOSING LOOPS SUPPLIED BY AIRTEC.

  • Page 16: Velcro

    CYPRES USER’S GUIDE The control unit should be attached using the four small nylon ties built into its bottom surface. These ties can be pulled through nylon layers with a needle and then secured with appropriate knots. This method of attachment places the knots out of sight and is therefore visually pleasing.
  • Page 17 Once the control unit has been mounted, make sure that it cannot interfere with the reserve container opening, the ripcord, the pin(s). Inside the reserve container, the nylon pockets supplied with CYPRES must be used to install both processing and release units. The nylon cable housing should be used to encase all cable.

  • Page 18: How To Operate Cypres

    You should familiarize yourself with switching CYPRES on and off and changing reference altitudes (pages 17, 18, 20 and 21) prior to installing and using it. The pushbutton is the only means the user has for controlling CYPRES functions. Through it, the following four actions are initiated: •...

  • Page 19: Switching Cypres On

    CYPRES USER’S GUIDE 4.2 Switching CYPRES on CYPRES is switched on by pressing the pushbutton four times with short dry clicks. You initiate the switching-on cycle by clicking the button once. After approx. one second, the red LED-light will glow. You must acknowledge the red light immediately by clicking the button again.

  • Page 20: Switching Off

    CYPRES USER’S GUIDE Any functional defect will also cause CYPRES to abort the self-test and display a number for approx. two seconds before switching itself off. This number is an error code. Error code numbers are listed on page 24 along with their respective causes.

  • Page 21: When To Switch On Or Off

    • If the total flying time for a single jump lift exceeds one and a half hours CYPRES will function normally but must be re-set after landing. When the airfield and dropzone are in different locations, CYPRES must be switched on at the departure airfield.

  • Page 22: Changing Altitude Reference

    (30 or 10 ) In this way, CYPRES is asking if the intended landing spot will be at a place 30 feet (10 meters) above airfield elevation. The figure "30" ("10") will remain on the display but the arrow will switch direction, now pointing downward (30 or 10 ).
  • Page 23 In such a case, CYPRES must be recalibrated to the correct Ground Zero by switching it off and on again prior to the next jump. Do this on the airfield where the aircraft will take off.

  • Page 24: Water Jumps

    CYPRES USER’S GUIDE 4.5 CYPRES and water jumps When you intend to perform a water jump, you must remove CYPRES prior to the jump. Do not reinstall it until the rig has been dried out completely, because CYPRES is NOT moisture-proof.

    8998), it is absolutely necessary to change the battery. Because of special characteristics of the battery, it is possible, that a second try to switch the unit on will be successful. In this case it is not guaranteed, that the CYPRES will work correctly.

  • Page 26: Maintenance

    6. Maintenance 6.1 Removal of the unit Once CYPRES has been installed, it can be removed from the rig without requiring the services of a rigger. This will take approx. three minutes once the reserve container has been opened. Reinstallation will require a similar time, not including the pack job.

  • Page 27: Replacing Battery

    CYPRES instead. Stick-type batteries have a lower energy density, different temperature ranges, discharging characteristics, etc. CYPRES has been designed to be small so it takes up as little space as possible in your reserve container. Consequently, its wiring attachments and closure elements are small and delicate.

  • Page 29: Battery Cable

    CYPRES USER’S GUIDE Disconnect the blue battery plug, which has now become visible, by holding its blue plastic cover at its exposed end and pulling it out of its casing. You must NOT use the battery cable coming out of the housing to pull out the plug, because this might destroy the contact inside the processing unit.
  • Page 30 A breakdown means that the battery has been rendered unusable. Therefore, please use caution in handling CYPRES' batteries. Once battery replacement has been completed, the unit's operational status should be tested by performing one switch-on and switch-off procedure.

  • Page 31: Changing The Release Unit

    CYPRES is provided with the field replaceable cutter. It can be recognised by the plug on the release element cable. A CYPRES with an "old" cutter must be returned to our Service-Center in the US hostessed by SSK Industries, Inc. or your local CYPRES dealer.

    — methods for checking and measuring all aspects of the unit's accuracy in order to ensure it will function properly, even in extreme conditions. Please keep the container in which CYPRES was shipped to you and use it to ship the unit for technical evaluation to your local CYPRES dealer. When preparing CYPRES for mailing, please stow the cables in a clockwise direction around the processing unit.

  • Page 33: Important Notes

    CYPRES' proper functioning. Should a jump pilot be unable to comply with these requirements, or should you discover after a jump that the requirements have not been met, you should switch CYPRES off and on again prior to the next jump. Page 32...

  • Page 34: For Users

    • A Student or Expert CYPRES will not work if the aircraft is exited before it reaches 1500 feet (450m) above the height at which the jumper intends to land. In case of a Tandem CYPRES 3000 feet (900m) have to be reached.

  • Page 35: Repacking Of Reserves

    The looped end of the CYPRES loop should be impregnated with silicone except for 1/2" next to the disc. Ready-made loops provided by Airtec have already been treated with silicone the first 2". Running loops should be impregnated completely.
  • Page 36 In addition, we suggest that you prepare one further reserve loop of the appropriate length when installing CYPRES, and leave it together with the disc and a CYPRES pull-up (2 with a two-pin CYPRES and two softbodkins with two-pin Pop Tops) in the nylon pocket along with the stowed cable.

  • Page 37: Packing One-Pin Reserve Containers

    CYPRES USER’S GUIDE 8.1 Packing of one-pin reserve containers When packing a one-pin reserve container in which CYPRES has been installed, be sure to note these important points: • Use only original silicone impregnated CYPRES loops and original CYPRES discs (delivered with the unit.).

  • Page 39: Packing Two-Pin Reserve Containers

    CYPRES USER’S GUIDE 8.2 Packing of two-pin reserve containers These points apply when packing a two-pin container in which CYPRES has been installed: • Use only original silicone impregnated CYPRES loops (delivered with the unit). The use of thicker loops could prevent proper functioning of the system.

  • Page 40: Packing One-Pin Pop Top Reserve Containers

    • For one pin Pop Top systems Airtec recommend that the closing loop is not silicone impregnated. If your CYPRES is for this type of rig please ask the authorized rigger doing the installation to fit a non-impregnated loop. Except for these instructions, follow all other regular packing procedures described by your system manufacturer.

  • Page 41: Packing Two-Pin Pop Top Reserve Containers

    The ends should be folded back and sewn in place in exactly the same way as on those supplied by Airtec. Handstitch the running loop housing to the top disc of the pilot chute with strong wax thread. Cross-stitch all four corners.
  • Page 42 CYPRES USER’S GUIDE Loop installation in two-pin containers CYPRES loops should not be shorter as those normally used on any particular harness container system (rig). a) Assess the loop length required and adjust the loops accordingly. b) Then, stretch the loop by pulling tight on both ends at least twice. The pulling force is what matters, not the duration of the pull.
  • Page 43 CYPRES USER’S GUIDE Packing There is a simple technique using two special lines made of CYPRES loop material (soft bodkins) together with the CYPRES pull-ups. These lines and pull-ups will be shipped with every CYPRES ordered for a two-pin system. The packing procedure is described on the next pages.
  • Page 44 CYPRES USER’S GUIDE Altogether four packing lines are needed, two soft bodkins and two pull up cords. Both types will come together with your CYPRES. With pull up pull up the soft bodkins, pull the pull ups through the freebag, the release elements and the bottom of the container.
  • Page 45 CYPRES USER’S GUIDE After the pull-ups have been pulled all the way through the bottom of the container, their ends can be tied together. Then with the rig placed at the edge of the packing table, it will be possible to step into the...
  • Page 46 CYPRES USER’S GUIDE In order to facilitate the packing procedure described on the last three pages, we recommend that you pass 2 conventional metal bodkins through the grommets at the bottom of the container, serving as a mechanical aid for the closing of the flaps.

  • Page 47: Additional Notes To The Racer And Racer Elite

    On Racer and Racer Elite systems in countries where US TSO standards apply, you must use the quick loop system in accordance with the manufacturer's instructions. For both Running loops and quick loops however, you must use CYPRES polyamide loop material. Do not use silicone on quick loops.

  • Page 48: Abbreviated Users' Guide

    9. Abbreviated User's Guide ! Activate CYPRES only when on the ground, never in the aircraft ! When airfield and dropzone are in the same place, always switch CYPRES on or off and back on again when • it arrives at the dropzone by any means other than under an open canopy (e.g., by car or by walking back from landing away from the dropzone.)

  • Page 49: Installation In A New Rig

    It is no problem to remove CYPRES from your old container and assemble or install it into a new one (see chapter 3). If your new container is equipped with a CYPRES set up, your Rigger / Reserve Packer can easily assemble the CYPRES using the existing nylon pocket, cutter mounting(s) and cable housings.

  • Page 50: Regarding Air Travel

    Therefore, we suggest that when you travel with your CYPRES-equipped rig, check it in at the counter with other luggage. When doing so, make sure that CYPRES has been switched off. However, it could still happen that your gear will be X-rayed during a luggage check, or because you have decided to take it on board as hand-carried luggage.
