power up. If external AC power is not supplied on power-up, then the External Power
LED blinks red along with No Communication LED. Other status LEDs may also blink.
NOTE
Sensor status indications are not valid immediately after power-
up of the LDR
.
E. ABOUT JUMPER-SET OPTIONS
The Strike Guard Lightning Data Receiver offers several shorting-jumper-set options to
allow the user to select certain preferred features. These jumper-set options are preset
at the factory to conservative values that are appropriate for many lightning warning
settings.
Always turn the power switch OFF and remove the external power cord to the LDR
before opening the LDR. For equipment and personal safety, turn the power switch OFF
and remove the external power connector before:
1. Changing batteries
2. Changing jumper settings
3. Connecting wires to the control connector
Damage or electronic upset may occur if equipment is serviced when powered. To
prevent electrostatic discharge damage to components on the LDR printed circuit board,
always hold the stainless steel cover of the LDR in one hand while using the other hand
to change jumpers, reducing the risk of electrostatic discharge between your hand and
the circuit board.
