DGC-6D
Automatic Engine Controller
1.1 Introduction
• The Microprocessor / microcontroller based DGC-6D automatic generator
start and supervisory device is designed keeping in view the ease of operation.
• Housed in 96 x 96 flush mounted enclosure, is an ideal replacement of logic
based AMF.
• The functions of the discrete logic based AMF units are built in to one single
compact device, resulting in simplified panel wiring and size reduction.
1.2 Salient features of the DGC-6D
1.2.1 Protection & Supervision:
• 3 phase Under & Over voltage protection for EB supply (True RMS
measurement)
• Phase under & over voltage protection of Generator supply (True RMS
measurement)
• User programmable Cranking attempt.
• Generator over speed supervision
• DC Battery Voltage supervision (Under & Over voltage)
• External fault detection (2 digital inputs)
• External engine running signal
• DG Fail to Start supervision and indication
• DG fail to Stop supervision and indication
• Unit remains fully operational even if battery voltage falls to zero volts for one
sec.
