SC 370
Operation Overview
An internal view of the SC 370 is shown
in
Figure
1-1.
Component
layout
diagrams with part names and numbers are
shown in Figures 6-1 (AC) and 6-2 (DC).
Internal wiring diagrams are shown in
Figures 2-22 – 2-26 (AC) and 2-27 – 2-31
(DC).
Input power is connected to terminal block
TB1. Mounted on TB1 is a Metal Oxide
Varistor (VR1) which reduces line surges
and transients. Input power fuses F1 and
F2 are also mounted on TB1. Disconnect
power from the SC 370 before servicing
the fuses or MOV.
Fuse holders are
hinged on the lower side. Pull down and
open the side cover to access the fuse.
Power supplies located in each SC 370
unit convert input power to the correct DC
operating voltages for the system.
The
control
PCB
(PCB1)
supervises
system operation. A User Interface with
alphanumeric display and pushbuttons
provides system configuration and alarm
notification.
Note:
Shown with Modem, WiFi and GPS options. Printed Circuit Board colors may vary.
