18 Useful Information ■ How to prevent the programming by key-pad It is possible to prevent any access to programming by keypad by modifying the selector under the power supply slot (see the drawing on the left), or closing the contact number 1 of the digital input module, when present. Selector: turn the selector with a little screwdriver. - Free programming. - Lock programming.
Useful Information 19 tiples are automatically selected by the instrument according to the selected VT and CT values; • HiE: (maximum electrical scale) 100.0 K; the K and M multiples are automatically selected by the instrument according to the selected VT and CT values; • LoA: (minimum electrical scale of the analogue output) 20.
20 Useful Information ■ What is ASY The ASY variable allows the user to control the symmetry of the delta voltages (for systems without neutral) and star voltages (for systems with neutral). The variable is calculated according to the following formula: ASY= Where: Vmax - Vmin Vavg *100 Vmax is the max. value among VL1-N, VL2-N, VL3-N Vmin is the min.
Useful Information 21 ■ Alarm digital output The activation of the alarm can be UP or DOWN depending on how the ON and OFF parameters have been set, as per the following table: ON-OFF VALUES STATUS ALARM TYPE ON ≥ OFF UP ON < OFF DOWN ■ Displaying of programming menu It may be useful to know that the menus displayed by the instrument depend on its configuration; e.g.: the instrument will not display the menu relevant to the digital outputs if the optional module is not inserted.
22 Installation ■ Preliminary operations Before switching the instrument on, make sure that the power supply voltage corresponds to what is shown on the side label of the relevant module. ■ Before mounting the modules To know in which slot every module is to be mounted, refer to the figure on page 24. For a correct mounting of the instrument, insert the modules in the relevant slots, then, at the end, enter the central module, which can be a blind type module or an RS232 communication module.
23 Installation ■ Overall dimensions and panel cut-out ❑ Mounting Insert the instrument (holding its front) and fasten it (from the back) by fixing the two lateral brackets (1) (supplied with the instrument) to the appropriate location (2), using the two screws (3) supplied with the instrument. 2 1 3 Optional module connections 22 31 ▲ ▲ Useful information 21 27 877) 268-3700 · www.carlogavazzisales.
