WARNING: If this instrument is not installed and used in accordance with these
instructions, the protection provided against hazards may be impaired.
To meet the requirements of EN 61010-1 standard, where the unit is permanently connected to
main supply, it is obligatory to install a circuit breaking device easily reach by the operator and
clearly marked as the disconnecting device.
To guarantee electromagnetic compatibility, the following guidelines should be kept in mind:
• Power supply wires should be separately routed from signal wires and never run in the same conduit.
• Use shielded cable for signal wiring.
• Cables section should be ≥0.25 mm².
Before connecting signal wires, signal type and input range should be verified to be within the
right limits. Do not connect simultaneously more than one input signal to the meter.
CAUTION: Connect only one input signal range to the meter. Hazardous signal levels may be
present on unused inputs.
CAUTION: The isolation rating of the input common of the meter with respect to the option
card common and to the Logical Functions common (if used) is 250 Vrms and 500 Vrms with
respect to AC Power (terminals 1 and 2 of connector CN1). To be certain that the ratings are
not exceded, these voltages should be verified by a high-voltage meter before wiring the meter.
CAUTION:
1. Where possible, connect the neutral side of the signal (including current shunts) to the input
common of the meter. If the input signal is sourced from an active circuit, connect the lower
impedance (usually circuit common) to the imput signal common of the meter. (pin 1 CN2)
2. For phase to phase line monitoring where a neutral does not exist, or for any other signal input
in which the isolation voltage rating is exceeded, an isolating potential transformer must be
used to isolate the input voltage from earth. With the transformer, the input common of the
meter can then be earth referenced for safety.
3. When measuring line currents, the use of a current transformer is recommended. If using
external current shunts, insert the shunt in the neutral return line. If the isolation voltage
rating is exceeded, the use of an isolating current transformer is necessary.

Configuration:
When the power is applied to the meter, a display test begins automatically to check the function
of the LED’s and digits. Once this test is finished the display shows the internal software version
and then the unit goes to RUN mode.
Configuration follows a structure composed of a number of menus and submenus. By pressing
the ENTER key, the display show “Pro”. Pressing the SHIFT key repeatedly provides access
to the main menu level which includes menus for input configuration (CnInP), display
configuration (CndSP), relay configuration if present (SEtP), analog output configuration if
present (Anout), logic functions configuration (LoGIn). Press ENTER to access the submenus
under each main menu.
If configuration has been totally locked-out, when pressing ENTER to access the main menu
level, the display shows dAtA instead of Pro. This indicates that it is only possible to see
programmed information and that it is not allowed to modify any parameter from the entire
configuration. In this visualization mode, the meter automatically switches back to RUN mode
after 15 seconds sine the last key press.

Scaling
For linear signals, scaling is achieved by programming two coordinates (InP1, DSP1) and
(InP2, dSP2), between which is established a linear relation where each input signal value
corresponds to a display value. The relationship can be direct or reversed. In order to obtain
more accuracy, points 1 and 2 should be located approximately at both extremes of the process.

SCAL method
The input and display values are programmed manually. This method can be used when the
value of the signal at each points of the process is known.
tEACH method
The input values are introduced directly from actual electrical values. The input signal device
must be connected to the meter and operational when each point is programmed. The display
values are programmed manually. This method can be used when it is possible to bring the
process to the conditions of each one of the points to be programmed.
Weighted Average Filter P
0to 9 (4Hz to 0.05 Hz)
Sets low-pass filter cutoff frequency (Fc) which allows the meter to smooth out undesirable
display reading fluctuations. The value can be modified through the SHIFT key. This parameter
will set in reverse order the cut-off frequency of the low pass filter, getting the filter deactivated
for 0 value.

Configuration Lock Out
The meter is delivered with the programming not locked out, giving access to all the
programming levels. Once completed the meter programming the following security measures
are recommended:
1. Lock out the programming access to prevent from programmed parameters modifications.
2. Lock out Key Pad functions to prevent from accidental modifications.
3. There are two lockout modes: selective and total. If the parameters are going to be readjusted
frequently, make a selective lockout. If no adjustment is going to be made, make a total
lockout. Key Pad functions lockout is always possible.
4. The access to the lockout routine is allowed by entering a personalised code. We recommend
changing the code set at factory and to write down your personalised code and keep it in a
safe place.
TOTAL LOCKOUT
The access to the programming routines to read data is allowed even if all parameters are locked
out totLC=1, but it won t be possible to enter or modify data. In this case, when entering in
the programming mode, the display shows the indication “-dAtA-”.
PARTIAL LOCKOUT
When only some parameters are locked out, all configuration data can be read but only non
protected parameters can be modified. In such case, when entering in the programming
mode, the display shows the indication -Pro- “.
Menus or submenus that can be locked out are:
• Relay 1 configuration (SEt 1). If present in meter.
• Relay 2 configuration (SEt 2). If present in meter.
• Input configuration (InPut).
• Display (diSP).
• Display color (CoLor).
• Relay setpoints value (SPVAL). If present in meter.
• Analog output configuration (Anout). If present in meter.
• Logic inputs configuration (LoGIn).
• Direct access to MAX. and MIN values (MAHMn).
