SENTRON PAC4200

Battery replacement

SENTRON PAC4200 battery

must be periodically replaced.

For replacing, it is necessary to use an

angled pointed pliers with insulated jaws.

Note: SENTRON PAC4200 has no function

to determine charging status of battery.

Battery replacement steps:

1. Making sure that the replacement

battery has full charging capacity. It

must be available on site when battery

replacement service starts.

2. Saving device data.

• Opening dialog box "CHANGE

BATTERY":

SETTINGS > ADVANCED > CHANGE

BATTERY

• Selecting "START BATTERY CHANGE",

key <F4> (ENTER).

The operation launches data back-up.

SENTRON PAC4200 copies data from

volatile memory supplied by buffer

battery into internal non-volatile

memory.

The load profile configuration and the

load profile data are saved together with

all counter values, e.g. for energy,

day energy, operating hours, process

counters, universal counters, user

defined counters, interrupt counters,

event counters and configuration

counters. The device indicates complete

backup.

The following data could be lost, for

instance, when the battery is replaced:

event memory, min. / max. values for

all measured variables, date and time,

sliding window demand values. This data

can be backed up previously with

software.

3. Disconnecting the device from power

supply.

4. Replacing battery. The battery

compartment is accessible externally

without opening the housing. The

opening of the battery compartment

has the same shape as the battery

determining the alignment of the

terminals. It is not possible to insert the

battery incorrectly.

5. Ensuring old battery disposal in

accordance with standards.

6. Re-commissioning system. Restoring

supply voltage to device. The backup

data is available automatically.

7. Resetting time.

8. Testing SENTRON PAC4200

functionality.
