1.1 Front panel and value setup
In the measurement mode:
press the key 1 to scroll the measurement pages. press the key 2 to scroll the information pages of the instrument. Holding the button 2 pressed for at
least 3 sec., you access parameter programming and setting.
In the programming mode
press the key 1, to scroll the menus or increase/decrease the values to
be set up. With button 2 you can enter the submenus and change the value
changing mode from positive to negative or vice versa according to the logic indicated in g.3: Step “a”, pressing button 2, the letter C appears in the
bottom row, indicating the possibility to change
the values increasing them by means of button 1. Step “b”, pressing again button 2, -C appears in the
bottom row, indicating the possibility to decrease the values by means of button 1. Step “c”, To conrm the selected value, hold button 2 pressed until
the mark - of letter C
disappears. This way, the value is conrmed.
The frontal red LED (3, g.1) ashes proportionally to the measured imported energy.
Wrong phase sequence indicator (4, g 1), the hazard triangle is displayed in case of wrong phase sequence (L2-L1-L3, L1-L3-L2).
1.2 Programming block
It is possible to block the access to programming by means of a specic trimmer positioned on the rear of the removable display unit. Turn the trimmer
clockwise up to its run end with the help of a suitable screwdriver as shown in gure 2 point 5.
1.3 Basic programming and reset
To enter the complete programming mode, press the key 2 for at least 3 sec. (g 1). Entering the programming mode, all the measurements and control
functions are inhibited. During this phase the ashing of the LED has not to be considered.
1
PASS? : entering the right password (default value is 0) allows access to the main menu.
2
CnGPASS: it allows changing the password.
3
APPLiC.: it allows selecting the pertinent application. (A to F).
4
SYS :
it allows selecting the electrical system. 3Pn: 3-phase unbalanced with neutral; 3P: 3-phase unbalanced without neutral; 3P1: 3-phase balan-
ced with or without neutral; 2P: 2-phase; 1P: single phase.
5
Ut rAtio : VT ratio (1.0 to 999k). Example: if the connected VT primary is 5kV and the secondary is 100V, the VT ratio to be set is 50 (that is 5000/100).
6
Ct rAtio :
CT ratio (1.0 to 999k). Example: if the connected CT primary is 3000A and the secondary is 5A, the CT ratio is 600 (that is: 3000/5). Note: The
maximum VT by CT ratio is 1187 (max 5.5MW measured).
7
PuLSE: selects the pulse weight (kWh per pulse; programmable from 0,001 to 9,99).
8
t.on: T ON time (30msec or 100msec).
9
P. tESt:
sets the simulated power value (kW) to which a proportional pulse sequence according to “PULSE” corresponds. The function is active until
you remain within the menu.
10 tESt: activated on the pulse output when ON (for “APPLiC” C, D, E and F only).
11 Add. : serial address: from 1 to 247.
12 bAud: baud rate: from 9.6 to 115.2 kbps.
13 PAritY: no or even.
14 bStoP: StoPbit: 1 or 2.
15 enable or disable the display of THD values
16 EnE rES: reset of all the meters (for “APPLiC” C, D, E and F only).
17 End: it allows exiting the programming mode by pressing the key 2 (see g 1).
