Operation

Power Supply

Depending on the type of the device, there are different options of power
supply.
1. The basic TERZ 94 model is supplied by an internal lithium battery which
enables to operate the device continuously for a period of six years. This,
however, is conditional on the device being read once a week or "woken
up" by pressing the external button.
2. If an interface module is used for transmitting data, such as the ENCO
with external supply, the service life of the battery is more than 10 years.
3. The TERZ 94-S (current transmitter) is completely supplied through a
current loop. If pulse processing is to be maintained even in the case of a
power failure of the current loop, a standby battery (available as an option)
should be installed which will bridge the power supply during a period of
up to 6 months.
