2.4 Replacing the battery
In chapter 2.1, a picture can be seen where the location of the battery is indicated. The
battery is a CR2016 type, 3 Volt. Replacing the battery should be done with the power switched on.
If power is switched off and the battery is taken out, all battery backed-up memory will be lost.
The battery capacity is enough to retain all data for 1 year. The battery should replaced
every year. If the battery has been empty, the controller will show alarm 19 when starting up (see
also chapter 7). This means that if alarm 19 is shown on the display, the battery is empty already.
If the battery is empty, the following data will be lost:
-
Counters per program (chapter 6.3.1)
-
Counters per day (chapter 6.3.2)
-
Counters in total (chapter 6.3.3)
-
Time and date (chapter 6.6.1). Setting of time and date is especially important for the
counters per day (chapter 6.3.2) and the alarm history (chapter 6.7).
-
Last used program. After starting up with an empty battery, the controller will always
start up in program 1.
-
Cycle step. If the machine was running in a drying cycle or cool-down cycle, and the
controller is switched off, the controller will start up again at the same moment in the cycle. This
cannot be done any more if the battery is empty. In this case the controller will start up at the
beginning of a new cycle.
-
Delayed start. If a delayed start was configured and the controller is switched off, the
time until the delayed start is stored. Delayed start will be lost when the battery is empty.
-
Alarm history (see chapter 6.7). All recorded alarms will be lost when the battery is
empty.
