Portable Sequential Cushion System The TRINITY H.R. DYNAMIC™ mobile sequential cushion system is designed to help prevent the onset of pressure ulcers in home or hospital bound seated patients. This is achieved by means of a battery operated air pump unit inflating a cushion containing 4 rows of air cells, which are sequentially deflated automatically to provide relief. This allows a distribution of weight and a dynamic movement to reduce high interface pressures concentrating in specific points. The TRINITY H.R. DYNAMIC™ mobile sequential cushion inflation pressure is fully adjustable, monitored by the pump module, giving an audio and visual warning should the pressure drop below the alarm level. The alarm module gives an audio and visual alarm, should the pump unit stop cycling, and on a low battery condition.

Battery Capsule Pack (97-11-05-01 / 01.000) The battery capsule pack consists of a 6Volt NiMH 2.1AH cell pack with Integral Charge Controller with charger status indicator. The battery capsule pack is a sealed unit and other than charging does not require maintenance. The operation and the lifetime of the battery are greatly affected by how you handle the battery capsule pack. Take good care of the battery pack and follow the guidelines presented below. Fitting the Battery Capsule Pack The battery capsule pack slides into the pump case as indicated and locks into position, note the pack can only fit one way. To release the battery capsule pack depress the release button adjacent to the battery capsule pack, the pack will pop up allowing easy withdrawal. Using the Battery Capsule Pack A new battery's full performance is achieved only after two or three complete charge and discharge cycles. The battery capsule pack can be charged out of the pump unit, in the pump unit and with reduced capacity, whilst the pump is operating. The mains power pack and vehicle adaptor will allow recharging of the battery capsule pack whilst the pump is operating but they can not permanently power the pump unit, as after charging the battery the charger does not operate once the green charged lamp is illuminated, all power is drawn from the battery even if the charger power supply is still connected. The charger power supply would require to be disconnected and reconnected or switched off and on again to start a new charge cycle. Note the sensitivity of the charger control to voltage fluctuations will normally terminate the fast charge prematurely if the pump is operating. Use only the mains power pack and vehicle adaptor supplied with the system, the battery capsule pack requires a 3Amp fused supply of 12 to 16 Volt DC. The battery capsule pack can be charged and discharged up to 500 times but will eventually loose capacity. When pump operation times are noticeably shorter than normal, it is time to replace the battery capsule pack. For best operation times completely discharge the battery from time to time by leaving the power unit running until it turns itself off. Do not attempt to discharge the battery capsule pack by any other means.
50-50-15-02 V2 Page 12 TRINITY HR DYNAMIC™ SEATING SYSTEM USER & SERVICE MANUAL
If left unused a fully charged battery will discharge itself over time. Do not leave the battery in the pump if not being used. Recharge the battery capsule pack prior to storage and repeat the recharge every six months, preferably with a full discharge before charge as indicated above. Temperature extremes will affect the ability of your battery pack to charge, the status indicator will continue to flash red until the correct temperature is reached. It is best to allow the battery capsule pack to cool down or warm up first. Use the battery capsule pack only for its intended purpose. Never use any battery capsule pack which is damaged or worn out. The battery capsule pack is short circuit protected but may damage the connecting object. Accidental short circuiting can occur when a metal object (coin, clip or pen) causes direct connection of the + and - terminals of the battery pack (metal strips visible through the back of the battery capsule pack) for example when you carry a spare battery in your pocket or purse. If the battery does become short circuited the internal resettable fuse will reconnect the circuit after about 30 seconds. Leaving the battery in hot or cold places, such as in a closed car in summer or winter conditions, will reduce the capacity and lifetime of the battery pack. Always try to keep the battery between 15°C and 25°C (59°F and 77°F) especially when charging. When Discharging the capacity will be limited at temperatures above 45°C (113°F).and below -10°C (14°F). Do not dispose of the battery pack in a fire, or in municipal waste. They should be recycled, disposed of properly or returned to TALLEY GROUP LTD for disposal. Charging the Battery Capsule Pack For mains operation connect the 2.1mm plug into the socket on the top of the battery capsule pack. Connect the mains power pack to an AC wall outlet and switch on. Note the mains cord is fitted to the power pack via an IEC connector. The power pack green indicator will illuminate. For operation with the vehicle adaptor connect the 2.1mm plug into the socket on the top of the battery capsule pack. Connect the vehicle plug to a 12v accessory (cigar lighter) outlet, note that the ignition may be required to be switched on before the adaptor will operate, the indicator on the plug will illuminate if power is available. Charger Operation The battery capsule pack internal charge controller looks after all aspects of charging the battery capsule pack, The status indicator on the top of the battery capsule pack adjacent to the charge socket indicates the current operation to the user.
50-50-15-02 V2 Page 13 TRINITY HR DYNAMIC™ SEATING SYSTEM USER & SERVICE MANUAL
When power is applied to the charge socket the status indicator will flash red until conditions are suitable for fast charge to commence. During this time a low level charge is applied if the battery voltage is too low, or temperature conditions are inappropriate for fast charging whereupon the system will wait until the temperature returns to a suitable value. Status indicator will be continuously red while fast charging is in progress. This operation will normally give the bulk of the charge to the battery. It is terminated by a number of conditions dictated by monitoring battery cell temperature and voltage changes. Termination will normally occur when the battery is fully bulk charged, but will also terminate if abnormal conditions occur for safety, such as unsuitable cell temperature or voltage. The system next enters a charge top off phase with an amber indicator (red and green indicated simultaneously). A standard charge rate is applied for up to 3 hours to maximise battery capacity as the temperature falls after the fast charge. The fully charged status is indicated by the Green indicator. The battery capsule pack may safely be left connected to the charger indefinitely as during the charged indicator state a very low trickle charge is applied to offset the battery self discharge. The charge may be terminated during the top off phase (amber indicated) without great loss of battery capacity if the pack is required quickly. Battery capsule will become warm during fast charging. The battery does not have to be fully discharged before recharge, as the charger system will safely fill used capacity. It should be noted however that repeated partial recharging will inevitably reduce the net battery capacity to that which is being used as the unused capacity will degrade. Therefore you should fully discharge the battery pack from time to time by allowing the pump unit to run until it switches itself off, having exhausted the battery capsule pack, no other method of discharge should be attempted. If the charge period appears occasionally abnormally short this may be due to random chemical effects causing the charger to terminate prematurely. It is best to discharge the battery a short period and then recharge again. This may occur especially at high or low temperatures. If the battery pack system fails this is normally indicated by the status indicator flashing red indefinitely. The pack is not serviceable and should be replaced. If the mains power pack or vehicle adaptor fails to give an output the battery capsule pack indicator will not illuminate at all. Note that the mains power pack is not serviceable but the vehicle adaptor does include a 3Amp fuse in the vehicle plug.

Device Operation 1. Clip in Battery Capsule Pack. 2. Switch on unit 3. Pump unit will undertake a short lamp and sounder test at start-up (3 lamps will indicate and sounder will operate). 4. Next green light will come on and pump will start. 5. Set comfort setting as required. 6. To stop press the stop button (Sounder operate three times and both fault lamps will operate momentarily). 7. Note the Stop button is only operative after the initial lamp and sounder test (green lamp is illuminated). The pump unit will operate for many hours with a fully charged battery pack and will give an indication of low battery level when the associated warning alarm is issued, The green lamp will flash on and off and the sounder will operate every 5 seconds. The battery will exhaust after a period and the pump unit will shut down. The length of time the pump will operate after the low battery warning starts is dependant on many variables of settings and battery cell conditions but the unit is intended to run for about 1 hour but this is impossible to guarantee and some may run a great deal longer. The user should undertake to check how long their particular battery lasts after the warning starts. Note every battery may be different. Note that if the system appears to run the battery down more rapidly or the pump is operating for longer periods than normal and the inflation cycle slows there may be a slow leak or poor seal in the air system. As no low pressure alarm is issued the system is quite safe to use but should be serviced promptly to regain maximum efficiency from the system. The normal inflation cycle is about 10 minutes long consisting of eight periods of 72 seconds minimum, but the segment times may extent to 136 seconds each if the required air pressures are not achieved sooner. Longer period times are a good indicator that imperfect seals have occurred with time. If a major leak occurs or the pump fails then the low pressure alarm will operate. All systems faults that may give rise to potential risk will issue an alarm with a sounder on and off at 1 second intervals. If this occurs seek prompt maintenance.
