The BW-WM1 is a fully configurable three light warning indicator that can be used in a simple LOG100 mode. The green light extinguishes if there is a loss of signal from any transmitters. The amber light illuminates if any LOG100 display channel passes the warning level. The red light illuminates if any LOG100 display channel passes the over/underload level. A buzzer sounds with the red indicator (can be disabled for quiet use). Alternately, the BW-WM1 can be configured as part of a stand alone system. The values from up to eight data tags can be used to trigger each of the amber and red indicators (and buzzer). As well as showing that signals are being received, the ‘good’ green light can also be set to extinguish if other error states occur.
