SAVING BATTERY LIFETIME (TYPE PB)
In case of a battery powered application, lifetime of the battery is an important subject. To prolong
the battery lifetime as much as possible, it is strongly advisable to use only necessary functions, and
disable functions if not in use. Factors that influence battery life are:
● Analog output signal
● Display update: the fast display update setting uses significantly more power
● Pulse output signal
● Communication
● Optical key activity
● Low temperatures: the available power will be less due to battery chemistry
● NPN and PNP inputs consume more energy than coil inputs
● High input frequency.
For battery powered applications, disable the optical keys with the switch on the MEM where
possible to significantly reduce power consumption.
