IMFEC11 Communication Mode Jumper (J4)
The communication mode jumper sets the IMFEC11 communi-
cation mode. Table
lists the jumper setting for J4. Refer to
for the location of J4 on the FEC circuit board.
IMFEC11 Input Jumpers (J6 through J20)
Fifteen input jumpers allow selection of voltage or current
inputs. Refer to Table
for jumper descriptions.
Figure
shows the location of the input jumpers and also a
diagram silkscreened on the board that shows how to position
the jumper. Each jumper has a left pin, center pin and right
pin. For voltage, position the jumper on the left and center pins.
For current, the jumper would be on the center and right pins.
Termination Unit
Wiring from field devices connect to the INFI 90 OPEN system
through terminal blocks on a termination unit or module.
Refer to Table 3-4. The termination unit/module must be con-
figured before use.
If installing the FEC module in the analog input (IMFEC12) or
point-to-point mode on an IMFEC11 module, use the NTAI05
Analog Input Termination Unit (refer to
) or the
NIAI04 Analog Input Termination Module (refer to
Input jumpers (J6 through J20) on the IMFEC11 point-to-point
mode module must be set to the
voltage
position when using
either the NTAI05 termination unit or the NIAI04 termination
module.
NOTE: Refer to Figure
for location of input jumpers J6 through
for jumper descriptions.
If installing the IMFEC11 module in the field bus mode, the
NTFB01 Field Bus Termination Unit must be used. Refer to
for information on NTFB01 configuration for field
bus termination. Input jumpers (J6 through J20) on the FEC
module must be set the
voltage
position when using the
NTFB01 unit.
