While changing out my battery for the first time in my ping, the pump threw this code :Call Animas 052-0000. I called them and they said that they pump goes through several safety checks every minute and that somewhere between changing the battery and rewinding the pump it recognized something "not right" I had to take out the battery and start the rewind again. Once I got the pump rewinded and put a new cartridge in I hit the "load cart" button. In the middle of that the pump threw the code again and I had to repeat all the steps again. On the third try everything worked the way it was supposed to and the lady I was talking to at Animas said it was nothing to worry about unless it throws that code several times a month. I've only been pumping for a month now and I am not sure if I should be concerned about this or not. Any suggestions or advice? Ever had this happen to you before? I guess I'm just looking for some peace of mind. Thanks in Advanced!
