SECTION 1
GENERAL INFORMATION
1.1 INTRODUCTION
1.1.1 Purpose
This instruction book provides field support data and information for the FAA Type
L-847 Runway Circuit Selector Switches manufactured by Crouse-Hinds Airport
Lighting Products, Windsor, CT 06095. The equipment is herein after referred to as
a CSC.
1.1.2 Applicability
This instruction book applies only to that hardware bearing the part number series
84700. Instructions for standard options are provided in Section 6 of this document.
Refer to Table 1-1 for complete part number information.
1.2 EQUIPMENT DESCRIPTION
1.2.1 Function
The FAA Type L-847 CSC is a power switching cabinet specifically designed for
connection to the output of an FAA Type L-828 Airport Lighting Constant Current
Regulator (CCR). It is capable of switching one or more series lighting circuits
either locally or from a remote location, without affecting CCR operation.
1.2.2 Features
The CSC is designed to accommodate lighting loads of up to 70KW at 20 amps and
30KW at 6.6 amps. Standard models are equipped with from one to four circuit
capability in one NEMA 1 enclosure. Any combination of load circuits may be
energized simultaneously. Modular construction has been utilized to provide ease of
maintenance. A clear dead front cover allows safe inspection of high voltage
components without the need to de-energize the lighting system.
1.2.3 Options
A number of factory installed options are available. These options, listed in Table 11, enable the customer to configure the CSC for a variety of specific applications. It
is recommended that the customer contact Crouse-Hinds to verify the specific
options required for an application prior to order submittal. Option -1 is installed on
all units. See Section 3.1.4.

TECHNICAL DESCRIPTION
2.1 THEORY OF OPERATION
The operational discussion presented herein pertains to standard model CSC units.
Equipment supplied with options may deviate somewhat from the exact operational
description presented, but the basic operating principles are identical for all
equipment configurations.
2.1.1 Local Control
The CSC control circuits operate from the 120 VAC primary power source and
energize the relay coils in the high voltage circuit to supply power to the lighting
circuit selected. When switch, remote-off-local, is selected to LOCAL, switches S1
and S2 (S1 through S4) are active. When any of these switches is set to ON, a signal
is applied to the timing circuits located on the circuit card assembly. The timing
circuit, in turn, supplies power immediately to the coil of the respective double pole
relay in the high voltage section. After a brief delay, less than one second, the timing
circuit supplies power to the coil of the associated single pole shorting relay in the
high voltage section, thus energizing the lighting circuit. (Note: Due to the
characteristics of Type L-828 Regulators, the other lighting loads may dim
momentarily. This is normal.) To de-energize a lighting circuit, the respective
control switch is selected to OFF. This action immediately de-energizes the single
pole shorting relay, which places a short across the lighting circuit. After a brief
delay, the timing circuit removes power from the coil of the double-pole isolating
relay, which opens to isolate the lighting circuit from the regulator. The timing
diagram in Figure 2-1 may be helpful in understanding the switching sequence.
De-energized switching (Option -1) is installed on all units. This turns the regulator
off prior to switching the circuits and turns the regulator back on after the circuits
have been switched. See Sections 3.1.3.2 and 3.1.4 for more detail.
2.1.2 Remote Operation
The CSC, when operated remotely, functions exactly the same as when under local
control, except that switches S1 and S2 (S1 through S4) are not active. Remote
control power is normally derived internal to the CSC. However, external power
sources may be used if the proper option is specified.
2.1.3 CCR Interlock
An interlock switch is provided for the high voltage section of the CSC. This switch
should be connected in series with the control circuit of the CCR to provide for
immediate shutdown of the CCR in the event that the dead front cover of the CSC is
removed. Normally, however, the CCR or CCRs should be de-energized prior to
removal of the dead front cover

INSTALLATION AND OPERATION
INSTALLATION, SERVICE, MAINTENANCE OR OPERATION SHOULD
BE PERFORMED BY QUALIFIED PERSONNEL ONLY.
3.1 INSTALLATION
All CSC units are supplied ready for operation with all ordered options installed.
When properly connected, no electrical adjustments should be necessary prior to use.
3.1.1 Location
The CSC may be installed in all locations meeting the environmental requirements as
specified in paragraph 1.2.4.3 except where explosive or highly corrosive
atmospheres may be present. The equipment should be accessible to qualified
personnel only. In addition, adequate drainage should be provided to preclude the
possibility of standing water hindering maintenance or normal operations.
3.1.2 Power Requirements
Standard model CSC units require a source of 120 VAC at 50/60Hz. If the particular
unit to be installed is equipped with option -2, a source of 220 to 240 VAC at
50/60Hz is required. Refer to Table 1-1.
3.1.3 Detail Installation Checklist
NOTICE: (1) Read and become familiar with this procedure before
attempting installation of this equipment. Improper
installation procedures can damage this equipment and may
