OPEN THE HOUSING
PROCEDURE
1. Insert a screwdriver or similar tool in the
points marked c.
2. Turn the screwdriver until the case walls
begin to separate towards Aand B, so the
two side lugs e, are free.
3. Grab the Signal Conditioner body, at the
points marked d‚ and pull it towards C,
until the two side lugs eare out of their
housing and the internal circuits are visible.
See the sketch below for the disassembly of
the circuit boards.
4. Before reinserting the Signal Conditioner
body into the case, the following must be
checked :
-The front label (blue color) must be in its correct position, with terminals 1 and
7 (power supply) separated from the other terminals.
-The three internal modules must be inserted correctly in their internal case
guides.

are shown on the side label.
WARNING.- If the power supply is dc voltage, be careful with the polarity indicated for each
terminal.
The unit is not provided with a system to change the power supply. Therefore if the power supply
must be modified to other value, please replace the module MA for another one appropriate to
the new characteristics. Contact your local distributor for instructions.

to protect the operator and the process when
using the Transmitter to control a machine or
process where injury to personnel or damage to
equipment or process, may occur as a result of
failure of the Transmitter.

ADJUSTMENT AND CALIBRATION PROCEDURE
1. When input and output signal values are determined, remove the conditioner case. (Fig.2)
2. Check on the "MA" module, if the selected power supply is correct. (Table 1).
3. Select on the input board the desired Frequency range, according to Table 5, using
jumpers "1", "2", "3", "4", "5" and "6".( Fig. 8).
Set jumpers "7" to "10", for the corresponding signal type (Table 4).
Select on the "MS" output module the desired output (voltage or current), using jumpers
"E" and "F". (Fig. 6).
4. Connect a pulse generator to the conditioner input terminals 5 and 6
5. Connect a digital multimeter to the signal output terminals : 11 and 12 for Voltage output.
: 9 and 10 for Current output.
6. Power up the conditioner with the appropriate power supply.
7. Adjust the pulse generator until it generates the low signal level.
8. Turn the "ZERO" trimmer (P1), located on the "ME" input module, until the multimeter
shows the desired low signal output level. (For example: 0 Vdc).
9. Adjust the pulse generator until it generates the high signal level.
10. Turn the "GAIN" trimmer (P2), located on the "ME" input module, until the multimeter
shows the desired high output level. (For example: 10 Vdc).
11. Repeat steps 7 to 10, until the two values are correct.
Set the jumpers to the position indicated in Table 5 for each range. The jumpers are located on
the "MP" input board.
If the signal input is modified, follow the adjustment and calibration procedure.
