Troubleshooting

This Troubleshooting chapter is designed to help you understand the messages that your pump is giving you when you get an alarm or an alert message. The procedures in the beginning of this chapter are to be used when you get specific alarms or cover a likely condition that might happen. A list of alarms is provided at the end of this chapter.

NOTE -

It is recommended that you read your warranty statement included with your pump for information on what is covered during your warranty period.

My pump has a no delivery alarm...

When a “No Delivery” alarm occurs, it means the pump is working correctly but it has detected that something is preventing insulin from being delivered. Your pump is not broken. Do the following steps:

1 Check your blood glucose and take an injection if needed.

2 Make sure that there is insulin in your reservoir and the tubing is not kinked. If these are all right, go to step 5 .

3 If necessary, unkink tubing. Clear the alarm by pressing ESC and ACT . A screen will appear with two choices: Resume and Rewind . Select Resume .

4 If the reservoir is empty, clear the alarm by pressing ESC and ACT . Select Rewind and change your reservoir and infusion set per the instructions in chapter 4, “Starting on insulin.”

5 Continue troubleshooting by disconnecting at the quick-disconnect, and set a 10 unit Fixed Prime.

6 Does insulin come out of the needle at the quick-disconnect? a.

If yes, change your entire infusion set per the instructions in chapter 4, “Starting on insulin.”

If NO insulin comes out of the needle at the quick-disconnect, or you receive another No

Delivery alarm, call the 24 Hour HelpLine.

b.

Your pump remembers the last fixed prime you deliver, so make sure to set your fixed prime amount back to your usual setting. To do this, deliver another fixed prime in your normal amount (the amount specified in your infusion set instructions).

7 Monitor your blood glucose closely.

8 If you followed these steps and you are still receiving a No Delivery alarm, call the 24 Hour HelpLine.

What happens if I leave the battery out too long?

If you leave the battery out too long (more than five minutes), you may receive a BATT OUT LIMIT alarm message when you install the new battery. Do the following steps:

1 Set your pump clock to the correct time, date, and year.

2 Check to make sure that all your settings, such as basal rate, are set as desired. If need be, reapply your last saved settings to the pump by using the Restore Settings option under User Settings in the

UTILITIES MENU as described in chapter 8 (you can only use this option if you have previously saved your pump settings).

3 Check the ALARM HISTORY screen and the STATUS screen for any alarms and/or alerts that may still need attention.

If you leave the battery out for more than three or four days, you may receive an A17 alarm and several

A47 alarms when you install a new battery. Do the following steps:

1 Clear all A17 and A47 alarms.

2 Set your pump clock to the correct time, date and year.

3 Check to make sure that all your settings, such as basal rate are set as desired. If need be, reapply your last saved settings to the pump by using the Restore Settings option under User Settings in the

UTILITIES MENU as described in chapter 8 (you can only use this option if you have previously saved your pump settings).

4 Check the ALARM HISTORY screen and the STATUS screen for any alarms and/or alerts.

Why doesn’t my pump battery last very long?

A short battery life does not mean that something is wrong with your pump. Battery life in your pump is variable and based on the conditions below:

➠

➠

The brand of battery you use (we recommend Energizer).

The storage and /or handling of the battery before use (avoid high or low temperatures).

➠

➠

➠

The usage of pump in cold temperatures; this may shorten the battery life.

The usage of your pump, such as how often the buttons are pushed, the number of alerts/alarms and set changes.

The amount of insulin the pump is delivering.

➠ The usage of some features. The backlight, vibrate, remote control and/or meter options decrease battery life.

122 Chapter 9

What is a CHECK SETTINGS alarm?

This alarm occurs after an E alarm or after you clear your pump. It is advising you to make sure that all your settings are correct. A CHECK SETTINGS alarm occurs after any of these actions:

➠

➠

➠

All user settings were cleared (set back to their defaults) because there was an E-error alarm.

The “Clear Settings” function was performed.

After you rewind when practicing without a reservoir when your first get your pump. In this case, it is just a reminder to make sure all your settings are programmed before you begin using the pump with insulin.

My screen appears distorted

The screen may appear distorted or have a “rainbow” appearance if you are wearing polarized sunglasses, are in bright sunlight, or in extreme high or low temperatures. If your screen appears distorted:

➠

➠

Take off your sunglasses.

Move into the shade.

➠ Make sure your pump is not in direct heat (i.e., next to a heater) or cold (worn on the outside of your clothing on a very cold day).

Do not return the pump: this is a normal property of this type of screen on any device.

I cannot get out of the priming loop

1 Is there a filled reservoir in the pump?

➠ If no, place a filled reservoir or shipping cap in the pump.

➠ If yes, make sure you are disconnected from the pump.

2 Hold the ACT button until the second set of beeps and the numbers appear on the screen.

➠

If yes, your pump is okay, go to step 4 in the section “Manual prime” in chapter 4 to finish the

manual prime.

➠ If you did not hear a second set of beeps or numbers did not appear on the screen, change your infusion set and repeat this step.

3 If you still do not hear the beeps and see the numbers count up on the screen, call the

24 Hour HelpLine.

Troubleshooting 123

The pump is asking me to rewind

This is normal after any of the following:

1 Any E-alarms

2 Clear Settings function

3 No Delivery Alarm (during the Prime sequence)

My bolus stopped

The Bolus Stopped error can occur if the battery cap is loose or the pump was bumped or dropped during a bolus. It can also happen if the pump receives a static shock. As a safety measure, the pump stops the bolus when this happens.

1 If you dropped your pump, visually inspect it to make sure that it is not damaged in any way.

2 Review your bolus history and reprogram the remaining bolus, if needed.

My pump buttons are not acting right during a bolus

If the , or buttons are pressed and held down while a bolus is being delivered, the screen will freeze on that amount. Once the button is released, the units will ramp up to the amount delivered so far. Pressing and holding down the button will not stop the delivery of a bolus.

My pump won’t display my BG reading from my meter

1 Make sure that you are using the correct linked meter. Your pump will communicate with this meter only.

2 Make sure your meter is on (set to “snd”) and working correctly.

3 Make sure the meter option in your pump is set to On and you have set the meter ID number correctly on the pump.

4 Make sure your pump does not have a Low Battery alert condition.

5 Make sure the meter is within 4 feet (1.2 meters) of the pump without anything in between such as another person, a wall, etc.

6 Make sure there is no RF (radio frequency) interference from other electronic devices that could prevent communication. These devices can include some cell phones, cordless phones, televisions, computers, radios, other Paradigm pumps meters and pump remote controls. To restore communication, simply move away from these other types of devices, or turn them off.

7 Your pump will not show another reading. Make sure the pump is idle and the HOME screen is blank.

124 Chapter 9

8 If your pump still does not receive your BG reading from the linked meter, use the up/down buttons to manually enter your BG (in the ENTER BG screen).

I dropped my pump

Take care to protect your pump from being dropped.

1 Check that all connections are still tightly in place.

2 Check the LCD, keypad and pump case for cracks or damage.

3 Check infusion set, including the tubing connector and tubing for cracks or damage.

4 Review the status screen, basal rates and other pump settings.

5 Perform the Selftest procedure located in the UTILITIES MENU.

6 Call the Medtronic MiniMed 24 Hour HelpLine for assistance.

I submerged my pump in water

Your pump is designed to resist accidental contact with water. Do not submerge in water during bathing, swimming, or other water activities.

1 Pat the outside of the case until dry.

2 Open the reservoir compartment and check the compartment and reservoir for water. If wet, dry it completely within ten (10) minutes of exposure to water. Exposure to liquids, including water or insulin can corrode the mechanism.

3 Dry the reservoir completely—do NOT place a wet reservoir in the pump.

4 Do not use hot air to dry your pump. This may damage your pump's internal electronics.

5 Check the battery compartment and the battery—if wet, let them dry completely before using the pump.

6 Perform a selftest.

I cannot get to the User Settings menu

If you do not hold down while pressing ACT when you have User

Settings highlighted, you will see the following screen:

1 Go to the UTILITIES screen and highlight User Settings. Then, hold down

and press ACT.

Troubleshooting 125

Alert conditions

Your pump has a sophisticated network of safety checks and systems. If it detects an unusual condition that requires your immediate attention, it will beep or vibrate periodically to alert you. The pump will go into

Special mode (an open circle will display), and the backlight will illuminate.

➠ Dual Wave or Square Wave bolus delivery

➠ Pattern A or B is active

➠ Temp basal delivery

➠ Block feature is on

➠ Low reservoir

➠ Low battery

➠ Why are alerts important?

Your pump monitors activities and will alert you if a Special mode is active. Some alerts are a normal part of pump therapy, such as an active temporary basal. There are alerts that indicate a condition that is outside normal pump activity. For example, your pump notifies you with an alert when you need to replace the reservoir (LOW RESERVOIR) or replace your pump battery (LOW BATTERY).

What to do

When your pump beeps or vibrates notifying you that an alert condition exists:

1 Read and follow the instructions on the screen. Press ESC , ACT to silence an alert.

2 Check the STATUS screen to determine what caused the alert.

3 If the condition is due to a low battery, replace the battery.

4 If the condition is due to a low reservoir, monitor the reservoir volume frequently and change the reservoir when appropriate. Make sure you have a new reservoir, infusion set and vial of insulin with you.

Low reservoir alert

You can program the pump to sound an alert when either a specified number of units remains or a specified amount of time remains before the reservoir will be empty.

Low Battery alert

If you get this alert, DO NOT go to sleep without replacing the battery.

The backlight, Remote control and meter functions are disabled during a

Low Battery condition. If the alert type is set to “vibrate,” the pump will change to the audio alert “beep-medium.” Clear ( ESC , ACT ) this alert before you replace your battery.

Alarms

Your pump has a sophisticated network of safety checks and systems. If the safety network detects anything unusual, your pump notifies you of conditions that require your immediate attention. The backlight illuminates the pump screen and the alarm/alert message displays on the screen.

NOTE -

The STATUS screen shows any alarms and alerts that are active.

➠ Why are alarms important?

Your pump monitors activities and notifies you if there is an unusual pump status or your attention is required. When an attention alarm is active, INSULIN DELIVERY IS STOPPED and immediate operator interaction is required.

If the vibrate mode is on, all alarms and alerts start as vibrations and then change to beeps. For your safety, if there is no response after ten

(10) minutes, the beeps change to a siren. The siren continues every minute until the alarm is cleared.

when a solid circle appears, follow the instructions on the screen.

Troubleshooting 127

What to do
