1)
The RS485 interface is only available if the universal inputs 3 and 4 are not being used.
Note:
The first two steps are only necessary if the device is already in operation and the wiring needs
to be modified.
1. Remove the four screws that secure the housing cover. Now open the myDatalogEASY V3 .
Important note:
In the event of adverse weather conditions including rain or in a location
where water can penetrate from above, suitable measures must be implemented to protect the
device from penetrating moisture when the housing cover is open.
2. Remove the power supply unit from the myDatalogEASY V3 . Use the strap provided to remove the
power supply unit.
3. Then connect your sensors and actuators with the universal inputs and outputs. You will require a
cable with a 7-pin JST connector to connect the sensors and actuators to the RS232 interfaces.
Ensure that no current is present when establishing the connection. If you would like to use an external
supply or charging voltage, you should connect the corresponding cables with the V IN and GND
clamps in the de-energised state.
Important note:
Only a single cable must be threaded through the cable screw connections to
ensure the seal of the housing is not jeopardised.
4. Tighten the cable screw connections to secure the cables.
5. Affix blind plugs to all of the cable screw connections that are not required.
Important note:
All unused cable screw connections on the myDatalogEASY V3 must be
sealed watertightly using the blind plugs supplied. Otherwise the degree of protection for the
entire device is not guaranteed and the manufacturer's warranty is void.
