Intended Use (including indications for use)

The IW900 series Infant Warmers are designed to provide warmth to infants in the first few

weeks of life, when an infant's self-thermoregulation capacity may be reduced, or if external

thermal support is required or desirable. This may include neonates (including premature/low

birth-weight neonates) in Labor and Delivery (L&D) Room applications, thermal support of

premature/low birth-weight neonates and critically ill infants in neonatal intensive care units

(NICUs) and thermal support of infants/pediatrics less than 10kg in hospital nurseries.

Situations which necessitate unobstructed access to an infant or neonate, including during

resuscitation or surgical procedures, may indicate the need for a radiant heat source instead

of equivalent support devices such as infant incubators. The IW900 series warmers may

therefore also be used in the Operating Room.

The IW930/IW950 series Infant warmers are additionally intended to be used for intrahospital transport between the above-stated specialist treatment areas.

The IW900 series infant warmer is not designed or intended to be used outside of the

hospital environment. The IW900 series infant warmer is not designed or intended to be used

in ambulatory vehicles.

PART 2: OPERATION AND GENERAL INFORMATION

2.1

PRODUCT OVERVIEW

INTRODUCTION

The Fisher & Paykel range of radiant warmers is specifically designed

to provide a controlled source of warmth to Neonates.

MODELS

The IW910 Baby Control and IW920 Manual Control Mobile Infant

Warmers provide mobile and height adjustable warming wherever

needed.

The IW930 Series Baby Control and IW950 Series Manual Control

CosyCot™ Infant Warmers combine an integrated bassinet and

mobility base in four options:

IW931 Standard Size Bassinet & Mattress – Preset Base

IW932 Standard Size Bassinet & Mattress – Electric Elevator Base

IW933 Long Bassinet & Mattress – Preset Base

IW934 Long Bassinet & Mattress – Electric Elevator Base

IW951 Standard Size Bassinet & Mattress – Preset Base

IW952 Standard Size Bassinet & Mattress – Electric Elevator Base

IW953 Long Bassinet & Mattress – Preset Base

IW954 Long Bassinet & Mattress – Electric Elevator Base

To these base models optional accessories can be added to suit

your own particular warming needs

The IW980 Baby Control and IW990 Manual Control Wall Mount Infant

Warmers provide discrete and convenient space saving warming.

In Baby Mode (IW910, IW93x, & IW980 only), the infant warmers

provide stable control of the baby's skin temperature by automatically

adjusting the heater power to compensate for varying physiological

and environmental conditions. This is achieved using a

microprocessor which measures and updates the baby’s temperature

ten times every second.

HEAT CONTROL

In Manual Mode, all infant warmers provide user-adjustable heater

power and the option to monitor the baby’s skin temperature using the

DuoSense™ skin sensor.

In Prewarm Mode all models provide alarm and trouble-free prewarming of the heater.

DUOSENSE™ SKIN SENSOR

Safety is further enhanced by DuoSense™ skin sensor. This sensor

measures the desired skin temperature using two independent

sensors. These sensors are continuously compared to ensure

accurate and reliable skin temperature measurements.

OPERATING MANUAL

This service manual is intended to be used in conjunction with the

IW900 Series Operating Manual (185048344) and Installation and

Assembly Instruction Sheets (see part numbers below). The operating

manual & assembly instructions sheets must be read thoroughly and

all instructions, warnings, cautions and notes thoroughly understood

by all personnel working with warmers prior to use.

2.2 HEATER POWER CONTROL

2.2.1 MODES OF POWER CONTROL

PREWARM MODE

Power is fixed at 25% (total irradiance at 68 cm < 10 mW/cm ). This

is sufficiently low that minimal alarms need to be active but

sufficiently high that the heating element will keep warm and be

ready for immediate use.

MANUAL MODE

Power is adjustable in the range 0% to 100% in 5% steps.

BABY/SERVO MODE

Power is automatically controlled according to the measured skin

temperature to achieve the desired set temperature. The set

temperature is adjustable from 34.5°C to 37.5°C in 0.1°C steps.

2.2.2 DESCRIPTION OF POWER CONTROL

POWER COMPENSATION

The actual mains power delivered to the element is not equal to the

power displayed on the front panel of the controller, as the device is

continually monitoring the mains voltage level and compensating for

any slumps and surges that may occur.

In all power delivery modes the amount of mains power delivered to

the element is calculated as shown below.

PDelivered  PDisplayed

PCeiling V27.5%

100 V 2

Where:

PDisplayed

PCeiling

is the displayed power level (Power Display).

is the power ceiling (currently 100% for all models).

V7.5% is the nominal line voltage less 7.5% (e.g. 213V for 230V

device).

V is the current line voltage.

PDelivered

is the actual amount of mains power delivered to the

element. Actual power delivered should be constant for constant

power displayed.

RESOLUTION AND DUTY CYCLE

Power to the element is controlled with a triac and switched only on

mains zero crossings to maximise electromagnetic compatibility.

When in Baby Mode, the power is controlled to a resolution of 1%.

Power is delivered in an optimally smooth pattern of mains pulses

which repeats every 2 seconds at 50 Hz (1.7 seconds at 60 Hz).

This even power control helps to reduce ripple in the baby’s skin

temperature. The power level is automatically adjusted ten times

every second.

ALARMS

2.4.1 IW910, IW93X AND IW980 SERVO CONTROL MODELS

CHECK BABY ALARM

In Baby Mode this alarm means the output power has been at 100%

for at least 15 minutes indicating that the baby is slow rising to the

set temperature and should be checked. In Manual Mode this alarm

means the output power has been above 25% for at least 15

minutes indicating that the baby should be checked.

HIGH SKIN TEMP. ALARM

In Baby Mode this alarm means the baby skin temperature exceeds

the set temperature by at least 1.0°C. In Prewarm Mode or Manual

Mode this alarm means the baby skin temperature exceeds 39°C.

LOW SKIN TEMP. ALARM

In Baby Mode this alarm means the set temperature exceeds the

baby skin temperature by at least 1.0°C. This alarm is not active in

Prewarm Mode and Manual Mode. This alarm is disabled for 15

minutes each time baby mode is started and re-enabled each time

the skin temperature gets within 0.5°C of set temperature.

SENSOR DISCONNECT ALARM

In Baby Mode this alarm means a problem has been detected with

the skin temperature sensor. This may mean: (a) If '---' is flashing on

the Baby Skin Temperature Display the sensor plug is not inserted

fully into the socket, and/or (b) that one of the thermistor beads

within the DuoSense™ skin sensor does not agree with the other so

that the sensor can no longer be considered accurate. A bead

mismatch alarm occurs within 25 seconds of the sensor being

plugged in. Both meanings apply in Baby Mode, meaning (b) only

applies in Manual Mode and neither apply in Prewarm Mode.

2.4.2 IW920, IW95X AND IW990 MANUAL CONTROL MODELS

This alarm has three meanings:

CHECK BABY ALARM

(a) Manual Mode 15 Minutes

The infant warmer has been running in Manual Mode at over 25%

power for more than 15 minutes. The baby should be checked.

(b) Skin Temperature > 39°C

This alarm is accompanied by a flashing Baby Skin Temperature

Display (which is > 39°C). The baby should be checked.

The DuoSense™ skin sensor feature of the infant warmer has

detected a fault with the skin sensor. This alarm is accompanied by

a flashing Baby Skin Temperature Display. Ensure that the skin

sensor is fully plugged in. If skin sensor is faulty then discard it.

2.4.3 ALL MODELS

SEE MANUAL ALARM

If the LED is flashing then the software has detected a hazard, has

shut down the heater and entered this alarm state. If the warmer is

able to power up again an error code corresponding to the meaning

of the alarm can be obtained with use of the Information Mode (the

error code is preserved in non-volatile memory).

If the LED is on constantly and is accompanied by a rapidly pulsing

two-tone alarm then the hardware watchdog circuit has detected a

micro-controller failure.

If the LED is on constantly and is accompanied by a constant tone

then the overheat protector in the heater has tripped.

POWER FAIL ALARM

When this alarm is flashing the power to the warmer has failed.

NOTE: that this may mean the power switch (located on the front

panel) is on while the power at the supply wall outlet is

switched off.

2. Affix the wall bracket (1) onto the wall using suitable fasteners (2)

for the surface (e.g. for concrete use masonry anchor bolts, for

timber use 75 mm wood screws). Use all six fastening holes.

These are 6 mm (1/4”) dia. with 14 mm (9/16”) dia. clearance

holes.

NOTE: When securely fastened, the fasteners must withstand a

direct pull-out force of 370 N (83 pounds) per fastener. In addition,

all fasteners must withstand a downwards shear force of 200 N

(45 pounds) per fastener. The wall must be constructed to

withstand a bending moment of 150 Nm (111 foot-pounds) which

is applied to the wall bracket.

SYSTEM CHECK

This procedure is the recommended performance check for Fisher & Paykel Healthcare Radiant

Warmers. A check of calibration is included.

ALARMS CHECK

1. Switch the Power Switch on. Check that the increasing pitch start up sound

occurs and that the following alarm indicators, depending on the model,

flash momentarily: Check Baby, High Temperature, Low Temperature, and

Sensor Disconnect depending on model.

POWERFAIL CHECK

2. Test procedure for power fail alarm:

Turn ‘ON’ and power Warmer for at least 5 minutes to ensure full charging of

the supercapacitor.

Turn ‘O

’ warmer and unplug power cord from wall supply socket.

Turn the Warmer front panel power switch ‘ON’. Check that the Power-Fail

Indicator flashes and audible alarm sounds for at least 12 minutes.

The additional 2 minutes is to allow for variation amongst capacitors and

differing operating conditions that may occur amongst warmers.

If the Power-Fail alarm operates for less than 12 minutes, the Power-Fail

supercapacitor will need to be replaced as it may have insufficient charging

ability to provide an alarm time of at least 10 minutes by the time of the next

annual check.

Replacement supercapacitors may be ordered through your Fisher & Paykel

Healthcare representative using the following part number:

Part # 311040682 (Cap Super 1F 5.5V HT)

Alternatively, you may order a replacement Power PCB:

120V, Part # 043041004 PCB Assy Power IW900 120V

230V, Part # 043041003 PCB Assy Power IW900 230V

STUCK BUTTON

3. Press and hold Prewarm/Standby Button. Reconnect the power cord to the

wall supply. Check that the warmer starts correctly and that the See Manual

indicator flashes and audible alarm sounds. Release the Prewarm/Standby

Button.

NOTE: This check causes a Stuck Button error to occur which will be logged as

the last error that occurred as accessible via Information Mode.

4. Switch the Power Switch off then on again. Check that the warmer starts up

normally.

CALIBRATION CHECK

5. Enter Information Mode (refer section 2.5) and select EIN #5.

6. Ensure that the light is off. Measure the mains voltage at the wall outlet

supplying the warmer, using a calibrated voltmeter.

7. Calculate and record the measured voltage as a percentage of the device’s

nominal supply voltage which will be 120V or 230V.

8. Check that the top display reads the calculated percentage (± 5%).

9. Select EIN #4.

10. Check that the top display reads 3950 ± 20 (39.50 ± 0.2°C).

Information Mode.
