Insulin Delivery Alerts

Alerts display automatically on your t:slim X2 pump to notify you about pump safety conditions that need your attention. Alerts notify you with either a sequence of notes or vibrations, depending on the settings selected in Sound Volume. Alerts will repeat regularly every 5 minutes until they are cleared by pressing OK. This can cause the battery to deplete quickly. Pay attention to alerts and address them as soon as possible.

This article provides descriptions and best practices for some common insulin delivery pump alerts. Refer to the User Guide for a full listing of pump alerts and how to respond. If the alert you are experiencing persists, please Contact Us for troubleshooting. Please make sure to have the pump alert number and your pump serial number available at the time you contact us.

  3. Review proper cartridge load technique.

An active Temp Rate dropped below half of your lowest basal setting defined in your Personal Profile.

Alert 56 – Max Basal

The temp rate programmed will cause a time segment in your active personal profile to exceed your Basal Limit Setting. Therefore, the basal rate will be capped at/reduced to your basal limit for the duration of the time segment or temp rate timer.

How to Troubleshoot:

  1. Tap OK_button.png to accept the reduced Temp Rate. The reduced Temp Rate value is the same Basal Limit value that was set up in Personal Profiles.
  2. The Basal Limit setting is a safety feature which allows you to set a limit to the basal rate that is set in the Personal Profiles, as well as the amount of insulin that will be delivered when using a Temp Rate.
  3. The default Basal Limit is 3 units per hour. You can set your Basal Limit from 0.2 to 15 units per hour. Work with your healthcare provider to set the proper Basal Limit. To adjust the Basal Limit setting, tap OPTIONS > MY PUMP > PERSONAL PROFILES > PUMP SETTINGS > BASAL LIMIT.

Note: It is always recommended that you consult with your healthcare provider before making any settings adjustments.
