Mounting requirements
This instrument is intended for permanent installa-
tion, for indoor use only, in an electrical panel which
encloses the rear housing, exposed terminals and
wiring on the back. Select a mounting location having
the following characteristics:
1. It should be easily accessible;
2. There is minimum vibrations and no impact;
3. There are no corrosive gases;
4. There are no water or other uids (i.e. condensation);
5. The ambient temperature is in accordance with the
operative temperature (0... 50°C);
6. The relative humidity is in accordance with the
instrument specications (20... 85%);
The instrument can be mounted on panel with a
maximum thickness of 15 mm.
When the maximum front protection (IP65) is desired,
the optional gasket must be mounted.

Note: Terminal 4 can be programmed as:
- Digital Input (DI2) connecting a free of voltage
contact between terminals 4 and 16;
- 0... 12 V SSR Drive Output (OP4) connecting the load
between terminals 4 and 16;
- 12 Vdc (20 mA) transmitter power supply connect-
ing the 2 wire transmitter between terminals 4
and 1; for 3 wire transmitter connect terminal
4 to transmitter power supply input and termi-
nal 1 and 2 to transmitter signal output.

*For
ELKM43 servodrive models both Out2 and Out3
are to be selected as “M” in Conguration code;
Out2: open, Out3: close.
General notes about wiring
1. Safety regulations require a line switch marked as
instrument disconnecting device. This switch must
be easily reachable by the operator;
2. Do not run input wires together with power cables;
3. External components (like zener barriers, etc.) con-
nected between sensor and input terminals may cause
errors in measurement due to excessive and/or not
balanced line resistance or possible leakage currents;
4. When a shielded cable is used, it should be con-
nected at one point only;
5. Pay attention to the line resistance, a high line
resistance may cause measurement errors.
6. To avoid electrical shocks, connect power line at last;
7. Before connecting the instrument to the power
line, make sure that line voltage is equal to the
voltage shown on the identication label;
8. The power supply input is NOT fuse protected.
Please, provide an external fuse T type 1A, 250 V.

Factory reset - Default parameters loading procedure
Sometime, e.g. when you re-congure an instrument previously used for other works or from other people or
when you have made too many errors during conguration and you decided to re-congure the instrument, it
is possible to restore the factory conguration.
This action allows to put the instrument in a dened condition (the same it was at the rst power ON).
The default data are those typical values loaded in the instrument prior to ship it from factory.
To load the factory default parameter set, proceed as follows:
1. Press the button for more than 5 seconds. The upper display will show PASS while the lower display
shows 0;
2. Using and buttons set the value -481;
3. Push button;
4. The instrument will turn OFF all LEDs for a few seconds, then the upper display will show dFLt (default) and
then all LEDs are turned ON for 2 seconds. At this point the instrument restarts as for a new power ON.
The procedure is complete.

6. ERROR MESSAGES
Out of range signals
The instrument points out, on the upper display, the OVER-RANGE and UNDER-RANGE conditions using the fol-
lowing indications:
Over-range Under-range
The sensor break will be signalled as an out of range:
Note: When an over-range or an under-range is detected, the alarms operate as in presence of the maximum
or the minimum measurable value respectively .
To check the out of span Error condition, proceed as follows:
1. Check the input signal source and the connecting line.
2. Make sure that the input signal is in accordance with the instrument conguration.
Otherwise, modify the input conguration (see section 4).
3. If no error is detected, send the instrument to your supplier to be checked.
List of possible errors
ErAT Fast Auto-tune cannot start. The measure value is too close to the set point.
Push the button in order to delete the error message.
ouLd Overload on output 4. The message shows that a short circuit is present on Out 4 when it is used as ou-
tput or transmitter power supply. When the short circuit disappears the output restarts to operate.
NoAt Auto-tune not nished within 12 hours.
ErEP Possible problem in the instrument memory. The message should automatically disappear, if the error
persists, send the instrument to your supplier.
RonE Possible problem of the rmware memory. If this error is detected, send the instrument to your supplier.
Errt Possible problem of the calibration memory. If this error is detected, send the instrument to your supplier.
7. GENERAL NOTES
