1.3.2 Power supply
The quality of the instrument’s ground will determine the
accuracy and the safety of your measuring system. A proper ground
connection is needed to minimize extraneous electrical noise affects on
the measurement. A poor ground can result in an unsafe and unstable
operation. It is important that the instrument should not share power
lines with noise-generating parts such as heavy load switching relays,
motor control equipment, inductive loads, etc. If the condition of the
power line in the plant is poor, prepare a special power line and grounding.
5 V 2.4 A power supply adapter is used for the power supply. Power
supply pin (C type USB) is located at the rear side of the indicator in the
ABS indicator and and in SS variant the power supply cable will go
directly inside the indicator.
5V 2.4 A c type connector of ABS Nebula indicators.
1.3.3 Load Cell Connections
Suggestion: After load cell connected to the instrument, the welding
Near to the load cell is not recommended. Disconnect all
Connector’s from indicator before welding on the mechanical hardware.
Load cell connection detail is shown in Figure below.
In 4-wire installations the sense and excitation pins with the same
Polarity should be short circuited at the connector side.
