Operation Using the different channels: b a single display and a single keypad are provided on the device to read measurements and modify settings on all 12 channels b select the channel corresponding to a given circuit and then proceed as if the RMH were connected to this circuit alone b it is also possible to use all the channels at the same time see page 54. For this, all the numbers corresponding to the channels connected to toroids must be lit. The display will show three dashes. DB124928 t l I %(I al.) max I pre-al. t pre-al. (s) I alarm "on" = trip t alarm (s) "off" = no trip pre-al. alarm 1 2 3 4 5 6 7 8 9 10 11 12 Modif mA A mA A Using the display: b the display is used to read the earth leakage current, relay settings and messages transmitted by the Vigirex RMH. If no keys are pressed before the end of the display time-delay (30 seconds by default), the unit automatically reverts to the user-selected default display b information is displayed on the 3-digit display unit. The units for current (mA or A) are specified by indicators item 7. Delay settings are displayed in seconds b the number of the selected channel is indicated byindicators item 1. If all channels are selected, all the indicators of the channels connected to toroids are lit and, unless the values for all the channels are the same, the display will show three dashes.
