AD-LM 6 FE-Vario, AD-LMB 6 FE-Vario


The signal/fault indicator AD-LM 6 FE-Vario, for mounting at the front of the control panel, informs with 6 multicolour leds about errors or operating conditions with glowing or blinking. Because of the multicolour leds, it`s not necessary to change the leds for changing the colour. So it`s very easy to change the technical appliance. The AD-LM 6 Vario can catch and save short pulses at the inputs, and for resetting its possible to connect external buttons. The device comes with 12 independet inputs which are easy to allot to one or more leds. Its possible to generate a colour- change by changing the input. A keypress on the touch key at the front of the device, generates a light test for all leds (all leds white). The AD-LM 6 Vario has a RS485 bus interface, which can used for the configuration over the AD- Studio (PC). All messages can be labelled with the aid of inserted strips (i.e. paper, foil etc.). This signal/fault indicator is also available with no physical inputs as a bus version (AD-6 Vario LMB). This can be controlled by the remote terminal block AD-AB 32 or by an external master.
