Optional Scanning Monitor Interface

Optional Scanning Monitor Ready

•supply either three or five precision output current levels (6.6 A maximum) for series lighting circuits on airport runways and taxiways.

•accurately regulate the output current to within ±3% of the adjustable nominal level from no load to full load and with input voltage variations of –5% to +10% of nominal (-40 °C to +55 °C.

Optional input voltages available are 208, 220, 240, and 480 Vac.

The regulators may be operated manually or by 120 Vac or +48 Vdc remote control signals from a distant location (10,000 feet round trip using AWG #19 control cable). The universal remote control used in the LC-Type CCR requires no circuitry changes between 120 Vac and +48 Vdc remote control signals. Both 120 Vac and +48 Vdc remote control source signals (CCI) are provided.

Protective circuits automatically shut down the regulators if an overcurrent or open-circuit occurs in the series lightning circuit. After an input power loss, operation automatically resumes at the same brightness level within 5 seconds after input power is restored. Output lightning and current-surge protection is provided on all units.

The L-828 CCR monitoring options include Scanning Monitor Interface (SMI) and Scanning Monitor Ready (SMR).

The optional scanning monitor interface is a relay assembly that can be mounted internally to the front panel of the CCR. The relay assembly consists of four relays and sockets. The relay assembly is used to generate feedback signals concerning the CCRs operation to the Remote Multiplexer. The relay assembly generates feed back for the following signals: Remote/local status, commanded ON status, regulator running status, and primary power status.

The optional scanning monitor ready includes the scanning monitor interface plus one current transformer (CT) and one potential transformer (PT). It also has resistor loads, and a fuse in the potential transformer secondary. Differential signals presenting the actual series circuit voltage and current are transmitted to the scanning monitor system two-conductor shielded cables.
