INSTALLATION RECOMMENDATIONS
11.2.1
•
Electronic and analog signal drivers must run the plant separately from the power supply and output conductors, if possible on grounded
conduits.
•
The power supply for the electronic instruments must come from a proper power grid for instrumentation.
•
It is recommended to use RC FILTERS (noise suppressor) in contactor coils, solenoids, etc.
•
In control applications, it is essential to consider what could happen when any part of the system fails. The device internal devices do not
guarantee full protection.
•
The electrical connections must be made with the device’s marked connection terminals. Before connecting them, make sure that the
connections have been made correctly.
•
Remember to wrap all wires inside the desired openings for passageways before making any electrical connections.
•
The power supply, digital output, digital input, and analog inputs terminals are not isolated from each other. Therefore, analog and digital signals
from the same power supply must not be used, otherwise the device will malfunction.
SPECIAL CARE
11.2.2
Due to
LogBox-BLE
being an electronic module, it needs some handling care:
•
When opening the cover that provides access to the connector for replacing the batteries, avoid contact with the connection terminals and the
electronic circuit due to the risk of damage caused by static electricity.
•
The device should not be opened due to the risk of damage caused by static electricity when the device is exposed to the electronic circuit.
•
Pay close attention to the sensor wires, the digital input, the digital output, and the external power supply connections.
ELECTRICAL CONNECTIONS
11.2.3
LogBox-BLE
has 4 detachable connection terminals for connection of external power supply, digital output load, digital input sensor, and analog
sensors for each of the 3 available analog channels.
Fig. 38
illustrates electrical connections in a basic way.

– Electrical connections
For the sensors connection, it is recommended that the connection terminals be previously detached from the device. To streamline the sensors
connection, use the enumeration printed on the connectors and the Electrical Connections image in
Fig. 38
, in the Quick Guide, and in the
Connections Protection Cover.
The power supply, digital output, digital input, and analog inputs terminals are not isolated from each other!
Therefore, analog and digital signals from the same power supply must not be used, otherwise the device will malfunction.
POWER SUPPLY
The connection to the Power Supply is made at the terminals according to the following
image. The power supply used must be of the direct current type, with a voltage
between 10 and 30 V and provide a minimum current of 15 mA when not connected to
the digital output. If the load is connected to the digital output, the power supply used
must be able to provide current compatible with the load used.
