Hibernate and Battery Life Information

The Pocket Pump features automatic powerdown (Sleep) mode a er 5 minutes in Hold. In Sleep mode the pump and

the display are oﬀ , however, the internal circuitry is still operating.

This function allows the internal computer to keep track of time. Although the other electronic circuits within the pump

are turned oﬀ , the microprocessor draws a signiﬁ cant amount of power from the ba ery.

If the pump is programmed with a running schedule, the pump will Sleep between the time it is programmed and the

time it is due to run. This will maintain the starting time information.

The pump is required to keep track of time, via an internal timer, to preserve the recording of operations in the history.

A er programs in the Pump Program Scheduler have been completed, the pump will enter Hold mode and the internal

timer will retain time for 24 hours. A er 24 hours, the timing mechanism will stop to preserve ba ery life. The timing

history up to this point is retained and the pump enters a low power state (Hibernate) to conserve ba ery life.

A fully charged and programmed pump will last for approximately 6 days in Sleep mode before the low ba ery

detection will switch it to the Hibernate state. (A program waiting to run will prevent the pump from entering the

Hibernate state until the low ba ery condition forces the pump into Hibernate). Although DataTrac will allow the

pump to be programmed up to 21 days in the future, it is advisable to load the program as close as possible to the

program start time. It is also important to download the pump history to a PC as soon as possible a er sampling.

History and Hibernate

The History shows the state of the pump at any instant including Run, Hold, Sleep, Hibernate, Low Ba ery Hold, and

Flow Fault. All these states have a time of day associated with them, so that a correctly timed history may be produced.

When a pump is programmed, a time reference is loaded into the pump from the PC. When a history is read from the

pump, the time reference is compared with the current time on the PC to ensure the history timing is consistent.

If a Hibernate state has occurred in the history, the time reference of the pump state before the Hibernate will be

determined from the starting time reference and the time reference of the pump state a er the Hibernate will be

determined from the current PC time at download.

If more than one Hibernate state has occurred, there will be running sequences that are bounded at their start and ﬁ nish

by Hibernate states. These sequences will contain valid timing intervals; but when the PC reads the history, the actual

start and stop times will be unknown.
