The device will not turn on when it is running on battery power.
If your device is not turning on, and the charge LED lights up when the AC power cord is plugged in, your battery may not have any power. If this is responsible for the issue, you must plug your device in with the AC socket. The AC socket is located at the back of the ventilator, and the internal battery will automatically begin charging when an external power source is connected to the ventilator. Allow for 8 hours of charge on your device using the AC power cord, before running the device on solely battery power.
If your device is not turning on and the charge LED will not light up when the AC power cord is plugged in, your device’s AC fuse may be blown. If this is responsible for the issue, both AC fuses in the ventilator must be replaced. Once the AC fuses are replaced, allow for 8 hours of charge on your device using the AC power cord before running the device on solely battery power.
Your device has difficulties after being powered on. It will not stay on or will not fully turn on.
If your device turns off without user intervention, the battery may have died. The AC socket is located at the back of the ventilator, and the internal battery will automatically begin charging when an external power source is connected to the ventilator. Allow for 8 hours of charge on your device using the AC power cord before running the device on solely battery power.
A defective electronic module can cause the device to continually lose power or restart over and over again. You can find a guide for replacing the electronic module at the following link, VersaMed iVent 201 Electronic Module Replacement.
The device’s display screen is unclear and hard to read for various reasons.
Your device may be powering up normally, but the display screen is black and the correct image can only be seen under extremely bright light. If this is the case, there may be a problem with the cable connection. To fix this, disconnect and reconnect the backlight and inverter board cables located at the back of the ventilator.
When the display image is upside-down, reversed, mono-colored, or fuzzy, yet the screen capture image is appearing unproblematic, there may be a problem with the LCD Connector. Disconnect and fully reconnect the LCD connector, and bend the retaining bracket outward from the device.
If problems persist, there may be a problem with the entire interface board. You can find a replacement guide at the following link, VersaMed iVent 201 Interface Board Replacement.
The control knob on the front of your device feels loose or worn out.
The control knob may have loosened over time due to usage. To fix this, tighten the encoder mounting shaft nut.
The battery indicator on your display screen reads empty, even after charge. The display screen may show a “battery notice”.
When the device continues to function properly but displays a “Low Battery” or “Empty Battery” alarm, the battery gas gauge may have accumulated error due to usage. To fix this, start by charging the battery for 8 hours. The AC socket is located at the back of the ventilator, and the internal battery will automatically begin charging when an external power source is connected to the ventilator. Once fully charged, discharge the battery until empty, then repeat and recharge the battery again for 10 hours.
If you have tried recharging your battery and the battery indicator still displays a battery empty icon, there is likely an internal problem. The electronic module needs to be replaced in your device, and a replacement guide can be found at the following link, VersaMed iVent 201 Electronic Module Replacement.
When the unit goes into functional failure but there is no empty battery alarm, the battery capacity may be inadequate and it may not be able to hold a charge anymore. The power pack needs to be replaced, and you can find a replacement guide for doing so at the following link, VersaMed iVent 201 Power Pack Replacement.
The device has some ventilator components that are not functional.
Depending on the flow sensor leak, the problem could be pneumatic or electronic. If the flow sensor leak is OK, then there is a pneumatic leak. The pneumatic unit must be replaced.
If the Flow sensor leak FAILED, then there is an electronic leak. If there is an electronic failure, conduct the Zero Sensors step of the Calibration procedure and repeat the VVT (exclude the attachment of the patient circuit). If the unit fails the VVT for flow sensor leak, then the electronic module must be replaced. You can find an electronic module replacement guide at the following link, VersaMed iVent 201 Electronic Module Replacement.
There are two versions of this component. The verification of this component independently can be performed by connecting an ohmmeter to the terminals and measuring the corresponding switch state. The switch’s normal state will be open, when there is no O2, and should close when there is high-pressure O2. However, it is best to call VersaMed service before adjusting or replacing it. You can find a guide at the following link, VersaMed iVent 201 O2 Pressure Switch Replacement.
There are two versions of the demand valve, one with a manual actuation button and the other without one. A positive pressure of less than 2 cm of H2O is needed to shut off the flow for the unit with the button. The version without the button will shut off automatically from a small amount of backpressure present at its output connector. Some demand valves will shut off as soon as manual actuation is lifted. While this is normal, nevertheless there should be no detectable leakage. If this still fails the VVT, there may be a problem with its position relative to the pneumatic unit’s O2 intake port.
