It should be noted that, when Delta Series units
are used to replace existing cartridge machines,
exchange of remote lamps will be required if the
Delta +5 VDC power supply is used as a source for
lamp voltage. Stations using the popular T-l 3/4
based lamps in remote indicators may replace them
with 5 volt versions. Lamps are driven in an open
collector fashion and should not exceed 140 ma. at
5 volts.
