l
TTL Signal is sent out through pins from CN2.
l
External voltage source is required for the TTL signal. The maximum
voltage is 50VDC and the maximum sink current is 30mA.
5.3 AC OK TTL signal ：detection of AC status .1
●
LAD-120: When the input voltage is abnormal, it sends out the AC
fault signal.
●
LAD-240/360/600xU: AC input voltage can be selected by 110V/230V
DIP switch.
115VAC input: When the input voltage is <75VAC, the AC fault signal
will be sent, and the main voltage will be restored when the input
voltage is greater than 87VAC.
230VAC input: When the input voltage is <165VAC, the AC fault signal
will be sent, and the main voltage will be restored when the input
voltage is greater than 175VAC.

5.3 Battery disconnected/reverse TTL signal: battery detection status .2
When the battery is not connected or reversely connected, the state is
high/low level, and the battery status can be known by detecting this
signal.
