The following step is only necessary if you are using an external supply or charging voltage.
11. Now switch on the external supply or charging voltage.
Note:
If you are using a power supply unit without an integrated energy store, the external supply or
charging voltage must be switched on before the optional step during which the connection to the server
is tested.
7.6.1.1 Connection examples
Connection examples
1
Main terminal block of the myDatalogEASY V3
4
2-wire mA sensor
2
Isolated relay contact
5
3-wire mA sensor or 3-wire U-sensor
3
Sensor with open collector output
Note:
The "Counter", "Frequency" and "PWM" operating modes require a permanent supply of the
sensors. One of the two switchable sensor supplies must be permanently active for this purpose. The
use of VEXT is recommended for this purpose (see sensor 1 in the connection example above). The
power consumption per input when the switch contact is closed can be up to 384µA due to the load of
10k086 .
7.6.2 Connecting the GSM antenna
Important note:
To ensure the correct functionality, only use antennas that are supplied by the
manufacturer.
The standard antenna (Portable antenna multi band FME-F , 206.826) is directly attached to the antenna
connector (see "Overview" on page 22) of the myDatalogEASY V3 . In the event of a low radio signal
strength, you can use the Flat antenna Smart Disc Multi Band FME-F 2m (300629).
If the distance between the antenna position and the myDatalogEASY V3 is too great, you can use a 5 m
Extension cable for antenna FME-F/FME-M 5m (206.805).
1. Ensure that the myDatalogEASY V3 is de-energised.
2. If you need an antenna extension, connect it to the antenna first.
