DC GENERATION
DESCRIPTION AND OPERATION
1. GENERAL (Figures 2 and 2A)
The DC generation system ensures the generation, regulation, control and indication of the direct current
generation. The aircraft is equipped with a 28-Volt DC generation system.
This sub-system consists of the following elements :
- regulator - overvoltage relay,
- alternator,
- battery,
I Pre-MOD. 182
- voltmeter integrated into the engine monitoring cluster - refer to 31-10-00,
- ammeter (option) if installed,
Post-MOD. 182
- voltmeter and ammeter integrated into the engine monitoring cluster - refer to 31-10-00,
S / N 1 - 9999
- alternator control,
- battery relay,
- keep alive fuse,
- amber (red on U.K. aircraft) warning light labeled "ALT"' on the advisory panel - refer to 31-50-00.

3. DESCRIPTION
A. Regulator - overvoltage relay Pre-MOD. 160
The LAMAR regulator and its integrated overvoltage relay are the elements which regulate voltage and detect generation system overvoltages. When an overvoltage occurs in the system, they cut off the alternator energization and the amber (red on U.K. aircraft) warning light labeled "ALTr" illuminates.
They are located above and to the right of the front table and fixed on the firewall on cabin side. Post-MOD. 160
The ELECTROSYSTEMS regulator and its built-in overvoltage relay regulate the voltage and detect generation system overvoltages. They disconnect the energization of the alternator in the event of system overvoltage.
It controls the illumination of the amber (red on U.K. aircraft) warning light labeled "ALTr" when it detects an overvoltage or an undervoltage condition.
It includes a LED to enable trouble-shooting.
It is located above and to the right of the front table and is secured on a support attached on the firewall.
