5-2-3 BRUSHES

An exciting current is supplied from the AVR to the rotor. The brushes are made of carbon, and the brush-holders of plastic. It is necessary to keep the contact pressure between the brushes and slip rings within specitic limits. Thus. care must be taken about brush length. (See 9-3 BRUSHES.)

5-2-5 VOLTMETER and PILOT LAMP

Models RGX340 and RGX21OD hav-e a voltmeter that comes in t\vo t>-pes: 15OV maximum tppe and 3OOVmaxi- mum type. The tl-pe of voltmeter indicates generator out- put voltages. The generators with a generated voltage of 11OV or 13OV and dual voltage type use the 15OV msimum t!-pe voltmeter: and those of 22OV. 23OV and 24OV specifi- cations use the 3OOVmaximum type voltmeter.

Model RGXISO employs a pilot lamp. The lamp hghts when a voltage is generated. The pilot lamp also comes in two types: 12% t>-pe and 3OV type. These t>-pes are selected to suit generator output voltage.
