Step 3: Open the Housing / Close the housing
Be sure that the mechanical installation of the instruments is done properly, and environment is convenient
to open the housing.
Open the housing from its rear. The rear part of the housing will be hanged to two stainless steel wires
connected to body.
Warning: Incorrectly closed cover and poorly tightened glands may be unwanted result with loss of IP rating
and safety. Close the cover's bolts with minimum 1.5 Nm torque.
Step 4a: Analogue Load Cell Connection
To avoid damages, the load cell wiring should be made carefully before energizing the instrument. Load cell
connection detail is shown in Figure 4.6. In 4-wire installations the sense and excitation pins with the same
polarity should be short circuited at the connector side. If you have junction box in your system, use 6 wire
cable between FT-111 and the junction box, and short circuit these pins at junction box for better
performance.
