Reassemble Corner Cap in reverse order. NOTE: Too many clips may result in unnecessary force and therefore potential damage to the side panel. To meet IEC regulations at least two Acetal clips should remain on each side of the bassinet. Remove all relevant side panels. Unscrew bolt 17 using a 5mm Allen key. For the front two corners the rear handle 10 should be removed from each corner prior to unscrewing bolt When fitting a replacement plastic corner cap , ensure the two lugs locate under the top surface of the corner block 3.
Tighten bolt 17 to a torque of 3Nm. NOTE: For version 2. For version 2. Refer to section 7. It is advised to replace the corner cap bushes at the same time as exchanging dummy axles.
The side panel sliding axle will need to be upgraded at the same time as the dummy axle to ensure correct operation. Follow steps a — c in section 3. Slide out the two dummy axles in each corner cap and remove the urethane bushes with a pair of pliers. Push a bush halfway into the corner cap before inserting the dummy axle.
A thin smear of a silicon grease should be applied to each oval axle stem prior to insertion. The sliding axles were modified in February to accept the lengthened dummy axles. All side panels made after this date will work with all versions of dummy axle. If you have an earlier version of the side panels then the sliding axles will need to be changed if they are to be fitted to a new version dummy axle.
Remove each side panel from the bassinet. Push one of the two sliding axles back to expose the grub screw which retains it. Using a 1. NOTE: The spring force could eject the sliding axle out of the extrusion if it is not securely held. Repeat step b on the other sliding axle and discard both sliding axles.
Replace with one of the new sliding axles and use Loctite to secure the grub screw back into the extrusion. Do not wind the grub screw fully in; at least 1mm should be left exposed to ensure the sliding axles are trapped in the slot. Replace the spring and then carefully push the second sliding axle in place and reinstall the grub screw using Loctite Disconnect all power and gas from the warmer and remove UPS modules, Side shelves, phototherapy lamps, gas cylinders and any other loose apparatus on the warmer.
Push the warmer from the front until the rear castors swivel round underneath the rear legs. Lock the rear castors. Stand behind the column and swing the head over to one side before carefully pulling the warmer column towards you so that the entire warmer pivots on the locked rear castors. Pre-position two chairs or stools in line with the column with one stool close to the base and gently lower the column onto them so that the entire warmer rests on the back of the column and no weight is on the base.
Preset bases manufactured prior to Feubruary can have the bassinet height adjusted to Refer to Figure 3. Using a 17mm spanner and 6mm Allen key remove the M10 x 30 screw and Nyloc nut 1.
Pull both sets of legs together until the desired hole on the lock bar 2 lines up with the hole in the pivot arm 3. Replace the M10 screw and Nyloc nut 1 and fully tighten. Preset bases manufactured after February can have the bassinet height adjusted to Using a 5mm Allen key remove the two M8x25 screws 2.
Pull the legs to gether until the other set of holes on the base adjustment bar 1 line up with the holes on the legs. Replace the M8 screw and fully tighten. There are only two adjustment points for this system. NOTE: Required on warmers with electric elevator bases and preset bases manufactured pre-February After this date a new preset system means that base level adjustment is not required. If the base or column are not level, then adjustment of the straight tie rod is required.
The straight tie rod is located underneath the base between the centre pivot and the rear legs. Undo the lock nut that secures the straight tie rod to the ball joints. In the middle of the rod is a flat section that should be used for adjustment. Use the 6 mm wrench part of the tool kit to turn the rod. One full clockwise turn of the rod thread M8 x 1. Hence, one full anti-clockwise turn of the rod will lift the column end up by approximately 4 mm.
Adjust to level column and base. NOTE: When the rod is assembled, the ball joints remaining threaded portions are:. If the castor is not vertical to the floor, adjustment of the link arms is required. The link arms are located underneath the leg. Castor angle cannot be adjusted on warmers after the above serial number — refer to PART for serial number identification. Undo the lock nuts that secure the straight tie rod to the ball joints.
Use a 3mm Allen key or a 3mm bar to turn the arm. One full clockwise turn of the arm thread M10 x 1. Hence, one full anti clockwise turn of the arm will move the castor inwards by approximately 3 mm. Adjust the castor to the vertical position. NOTE: When the arm is assembled the remaining threaded portions on both sides are 13 mm including 8mm thick lock nuts.
If the bassinet can be tilted without actuating the rear handle, or pulling the two handles together doesn't allow tilting of the bassinet, then the bassinet tilt clutch requires adjustment. Adjustment is performed with the adjuster screw for fine alterations or by moving the cable support block for coarse alterations. If Bassinet Clutch is too tight i. Loosen lock nut on adjuster screw and wind screw out. If screw is already fully wound out then cable support block will have to be moved.
Use a 4mm ball ended Allen key to loosen the two grub screws securing the cable support block to the bassinet frame. NOTE: On version three bassinets manufactured from November a single M8 cap screw has replaced the two grub screws, a 5mm Allen key is required to loosen this screw.
Wind the adjuster screw approximately half way out. Butt the adjuster screw against the cable sheath by sliding the cable support block towards the rear of the warmer. Fix the cable support block in position by tightening the two grub screws. Move the bassinet tilt brake handle backwards as far as it will go and wind adjuster screw out to take up tension.
Tighten adjuster screw lock nut. Pull the bassinet rear handle forwards and check brake release operation. If Bassinet Clutch is too loose i. Loosen lock nut on adjuster screw and wind screw in. If screw is already fully wound in then cable support block will have to be moved.
Wind the adjuster screw approximately half way in. If the clutch is still loose the actuator spring can be tightened. Referring to diagram in section 7. The 12mm washer part 16 should coincide with a line on the lower tilt link molding part 7. Cleaning the tilt brake sliders part 10 with alcohol to remove any particles can also improve the clutch performance. If the bassinet can be tilted without actuating the rear handle, or pulling the two handles together doesn't allow tilting of the bassinet, then the bassinet brake requires adjustment.
Move the bassinet so that the handle is in the lowest position. Loosen the lock nut on the adjuster screw. Wind the screw such that there is 2mm of play in the lower handle winding it out will reduce the play. Tighten the adjuster screw lock nut. To avoid the possibility of burns when performing cleaning procedures, ensure the warmer is disconnected from the power supply and the heater element is allowed to cool for one hour.
To avoid the possibility of electric shock hazard when performing cleaning procedures, ensure the warmer is disconnected from the power supply. If a UPS is installed ensure it is turned off prior to cleaning. Do not remove the UPS shroud during cleaning procedures. Ensure no part of the UPS is immersed in any cleaning agent. Do not allow liquids to collect or enter into any oxygen or air fittings or inlets. Explosion and fire hazards can exist when performing cleaning procedures in an oxygen-enriched environment.
Clean the warmer and accessories either weekly or between babies using the following cleaning procedures:. These contain plastic components made from polycarbonate or acrylic. This includes the entire head assembly, the side panels, the column cap, front panel fascias. Allow heated surfaces to cool before cleaning for at least 1 hour.
Do not use any compounds containing aromatic hydrocarbons, ammonia, amines or alkaline solutions. Thermal cut-out in Yes head has switched open circuit due to overheating. Reset thermal cut-out and. Watchdog for micro Yes controller has detected a fault in the control or. Figure 6. The location of major components and connectors on the PCB's are shown in Section 5. Full schematics are given in Section 5.
It holds the mains voltage parts and incorporates a heat sink. It provides a user interface, temperature measurement and intelligent control of the element power. Almost all of the warmer functions are implemented in software.
Five safety features are included which function independently of the micro-controller. These safety features are provided in addition to the safety features already provided by the micro-controller software. A comparator U12B is used to disable heat in the element if a skin temperature exceeding If a fault prevents the software alarm from occurring then this comparator will stop the micro-controller from applying power to the heater element.
The micro-controller will then cause a See Manual alarm with error code 17 because it will sense that it can no longer control the heater.
A counter circuit U13 is used to detect when uncontrolled mains voltage is applied to the heating element. It does this by counting how many continuous mains pulses are supplied to the element. If this count exceeds a threshold value then relays RL2 and RL3 will open thereby disconnecting the element from the mains supply.
Under normal conditions the software will not allow this to happen. If this circuit detects continuous full power in the element and opens the relays then the software will detect it is unable to control the element power and will show a See Manual alarm with error code An external hardware watchdog is included which monitors activity of the micro-controller. If the micro-controller is not regularly toggling the watchdog pin, then a See Manual alarm will be started see Section 2.
Power to the element will be disabled. If this thermal cut-out is tripped then relays RL2 and RL3 will open thereby disconnecting the element from the mains supply and a See Manual alarm will result see Section 2. The energy stored in the super capacitor C22 provides up to 10 minutes of pulsing alarm in the event that power fails while the unit is switched on. The remaining circuit components are used in conjunction with the micro-controller software:.
U8 contains the micro-controller software and many non-volatile presets are contained in U7. U7 can only be serviced by the manufacturer because it contains factory preset information. U6 provides an RS interface with the micro-controller. This is used for manufacturing purposes only. All user input is via the buttons or the control knob. The encoder SW11 has a two-wire quadrature output that allows the microcontroller to sense movement and direction.
U2 and U3 multiplex the buttons into a single line that is used as an input by the microcontroller. U1 drives the displays and indicators which are configured in four banks. A single line from U1 is used as feedback to the microcontroller test point TP9. Relay RL1 controls the examination light and U16 provides feedback on the state of the light to the micro-controller. Comparator U14E detects zero crossings and a waveform is derived found at test point TP14 which exhibits a momentary negative going pulse on each zero crossing.
A DC voltage proportional to line voltage level is detectable at TP8. The photographs below identify some of the major components used on the IW series of Infant Radiant Warmers and where they are located. NOTE: These are voltage specific with the voltage identified by a label on the mains isolating relay.
NOTE: 20x5mm fast blow fuses are available from standard electrical suppliers. The correct replacement fuses are listed on the label inside the front panel. The spare part numbers for ordering new Control PCB boards are:. RS Connector. It is not voltage specific. The following diagrams are an enlargement of the top left section of the Circuit Diagram on page 41 and show the fuse ratings for the different models.
See PART for warmer serial number identification. From August changes were made to the upper and lower cases of the head assembly to facilitate an additional bracket at the rear of the head. This version of head is most easily recognisable by the extra screw on the bottom face of the head in-between the former hinge.
NOTE: The lower case no longer swings down on a hinge. A new spares kit was created to allow the replacement of old style upper and lower cases The original aluminium light box was replaced with a black injection molded part from October The two M3 x 16 Taptite screws previously used for retaining the lamp receptacle are not required with the molded part which has snap fits for holding the receptacle.
In May the snap fits were altered to fit a new receptacle style. If a replacement light box is required for a warmer prior to this date then a new lamp receptacle will also need to be ordered. A new lamp receptacle was used from May This receptacle can not be retrofitted to earlier warmers. The original square receptacle will not fit into light boxes in warmers manufactured after May The date of manufacture of the head can be found underneath the head label 3 on the very top of the head.
This manufacture date applies to the head only and should not be used when referring to the warmer as a whole unit. As of June a bent wire tool is available for the removal of the head nut and replaces the plastic tool previously included in each warmer.
This contains a swivel head for the French Market. NOTE: If the reflector 13 is replaced it is important to ensure that it is correctly aligned inside the upper case 4.
The flats along each side of the reflector have steps cut out from either end to assist assembly. The reflector is placed in the plastic head molding such that aluminium flat is positioned under each of the four two per side plastic tabs in the upper case. The reflector should sit evenly in the head under the four front plastic tabs and Nomex. NOTE: Reflectors manufactured prior to June were not symmetrical, In this case the end with the two step cut out goes to the back of the head.
