LMM-8 (K, S, T)

Description
Light signalling panel for optical signal. The respective LED directly indicates the status of the input signal. The device has a collective signal output and a lamp test input. Lettering texts can be inserted into a foil front pocket: Signal storage ( -S ), potential-free collective alarm output ( -K ), integrated operating keys ( -T )
Function
LMM-8
The front foil is provided with an insertion pocket for a labelling strip. This can be labelled at the factory with a text of your choice in any colour. On our homepage you will find labelling templates as Word files for download.
The current required at the potential-bound collective alarm output must be provided by the active signal inputs. For AC voltage signals, only the positive half-wave is output. Connected inductive consumers, such as auxiliary contactors, must be connected with suitable protective measures to avoid overvoltages.
option -K
The module is additionally equipped with a potential-free collective alarm output (changeover contact 250V, 1A). The lamp test also activates this output.
option -S
After the loss of an input signal, the respective message remains stored until the LQ key is pressed for approx. 2 seconds (only in connection with option -T), or the neutral conductor is interrupted for approx. 2 seconds. If the LQ button is pressed while input signals are still present, only those LEDs which no longer have a signal at their inputs go out. The lamp test also activates the signal storage, the following lamp acknowledgement ( LQ key, N-wire interruption ) resets the LEDs and the collective signal outputs according to the status of the signal inputs.
option -T
integrated lamp test key (LP). In conjunction with option -S, integrated lamp test button (LP) and lamp acknowledgement button (LQ).
