IF303 – Operation and Maintenance Instruction Manual
4.2
If the problem is not presented in the table above follow the Note below:
NOTE
The Factory Init should be tried as a last option to recover the equipment control when the
equipment presents some problem related to the function blocks or the communication.
This
operation must only be carried out by authorized technical personnel and with the
process offline, since the equipment will be configured with standard and factory data
.
This procedure resets all the configurations run on the equipment, after which a partial
download should be performed. With exception to the equipment physical address and the gsd
identifier number selector parameter. After doing this, all configurations must be remade
according to their applications.
To run the factory Init, use two magnetic screwdrivers. Remove the screw on the equipment
that fixes the identification tag on the carcass top to access the orifices bearing the letters “S”
and “Z”.
The operations to follow are:
1) Turn off the equipment; insert the magnetic tools in each orifice (S and Z). Leave them in the
orifices;
2) Power the equipment;
3) As soon as Factory Init is shown on the display, take off the tools and wait for the "5" symbol
on the right upper corner of the display to unlit, thus indicating the end of the operation.
This operation has factory configuration that eliminates possible problems with the functional
blocks or the transmitter communication.
Disassembly Procedure
Refer to Figure 4.1 - IF303 Exploded View Make sure to disconnect power supply before
disassembling the converter.
To remove the circuit boards (
5
and
7
) and display (
4
), first loose the cover locking (
8
) on the side
not marked “Field Terminals”, then unscrew the cover (
1
).
WARNING
The boards have CMOS components, which may be damaged by electrostatic discharges.
Observe correct procedures for handling CMOS components. It is also recommended to store
the circuit boards in electrostatic-proof cases.
Loose the two screws (
3
) that anchor the display and the main circuit board. Gently pull out the
display, and then the main board (
5
). To remove the input board (
7
), first unscrew the two screws (
6
)
that anchors it to the housing (
9
), and gently pull out the board.
Reassembly Procedure
•
Put input board (
7
) into housing (
9
).
•
Anchors input board with their screws (
6
).
•
Put main board (
5
) into the housing, ensuring all inter connecting pins are connected.
•
Put display (
4
) into the housing, observing the four mounting positions. " ▲ " should point in the
direction desired as UP.
•
Anchors main board and display with their screws (
3
).
•
Fit the cover (1) and lock it using the locking screw (
