Dison BB-100
Dison · Model BB-100
Microprocessor based servo controlled temperature system Control modes: Air mode Humidity is adjustable continuously Set temperature, air temperature, heating power are displayed separately by LED Self - testing function, various failure alarms by audible and visual Alarm function: Power failure, Over temperature, Temperature deviation, Fan failure, Temperature sensor failure >37° temperature set function Triple protection for over temperature with separate cut off device, more safety system The inclination of infant bed is adjustable Single wall hood, 4 operating windows and 2 iris ports,3 infusion seals Independent locking device for front door.
Key tips
- ·Never skip temperature-accuracy verification to save time - it's the one check that directly prevents burns.
- ·Hose/blanket connector wear is the most common real fault and the easiest to miss on a quick visual check.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Air- or radiant-heater control fault
HighSymptoms: Chamber / patient will not reach or hold the set temperature, temperature alarm, self-test / "Check" fault.
Root cause: Heater element / infrared rod, the air- or skin-temperature sensor, the fan (incubator), or a control-board fault.
Skin-temperature (servo) control fault
HighSymptoms: Servo mode does not regulate to the skin probe, deviation alarm, probe-fault alarm.
Root cause: Damaged skin temperature probe or its connector, or the servo-control circuit.
Alarm / audible / power-fail-alarm fault
MediumSymptoms: No or quiet audible alarm, alarm lamp does not light on the self-test.
Root cause: Buzzer / speaker or the alarm board - a safety-critical failure.
Humidity / airflow fault (incubator)
MediumSymptoms: Set humidity not reached, uneven chamber temperature, airflow alarm.
Root cause: Humidifier reservoir / heater, or a worn circulation fan / blocked air filter.
Mattress / weigh-scale / tilt / access-port fault
LowSymptoms: In-bed scale inaccurate, tilt mechanism stiff, port latches or iris sleeves worn.
Root cause: Load cell, tilt actuator, or worn access-port hardware.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Hose / blanket connector inspection
- ·Temperature-accuracy verification
- ·Annual electrical safety test
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Heater / temperature control fault
- Run the readiness / self-test and confirm the alarm lamp and buzzer.
- Set a target temperature and confirm the unit reaches it.
- Compare the chamber / skin temperature to an independent calibrated reference.
- Check the fan runs and the air filter is clean (incubator).
- Replace the temperature sensor, heater element or infrared rod as isolated.
Symptom: Servo / skin-probe fault
- Fit a known-good skin temperature probe with good skin contact.
- Check the probe connector and cable.
- Verify the servo regulates to the probe with a warm reference.
- Replace the probe.
- Refer the servo-control circuit for service if it still will not regulate.
