1.1.10.1. Lightning Protection Module (Unit 1 A10 A1)
(See Figure 13, Point 1)
The lighting protection module protects the main Ethernet input from outside the Ranger-X5 radar
system.
1.1.10.2. Contactor, 3-Phase, 24VDC (Unit 1 A10 K1)
(See Figure 13, Point 4 and Figure 14)
The Contactor (K1) receives DC power from the Safety Replay (K2). When DC power is not
available, the Contactor (K1) is open (Normally Open) it removes all AC power to the remaining
power supplies on the DC Power Distribution Plate. This ensures the power in the pedestal is off
and the system stops radiating and the antenna stops moving.
Figure 14. Contactor (226-0516)
1.1.10.3. Safety Relay (Unit 1 A10 K2)
(See Figure 13, Point 3)
The Safety Relay (K2) receives DC power from the 24VDC Power Supply (PS1). The Safety
Relay receives command and control to open or close DC power output to the Contactor (K1)
from the E-Stop Control Switches on the E-Stop Panel (Unit 1 A12) and/or on the Pedestal Plate
Enclosure Assembly (Unit 2 A1 A5).
When an E-Stop Button is depressed, the Safety Relay stops sending DC power to the
Contactors (K1) and it opens. When the Contactor (K1) is open, it removes all AC power to the
remaining DC Power Supplies (PS2, PS3, and PS4).
