If a yellow or red range is reached, the affected data or value will blink in the appropriate
color. In addition, the yellow or red
ENG
warning light in the annunciator panel will
illuminate. In the case of a YELLOW warning light, the blinking can be stopped and the
alarm confirmed by pressing any switch on the MVP-50P-AQ.
7.15.2 Voltmeter and Amperemeter
The voltmeter shows the system voltage generated by the power sources.
The amperemeter shows the current flowing between the battery and the electrical
system of the aircraft. When the battery is being charged, the ampere values are shown
in GREEN. When the battery is discharging, the values are shown in YELLOW. This
means that when the battery is supplying the electrical system of the aircraft, YELLOW
values will be shown. During normal operation, this is a sign of an alternator
malfunction.
7.16 ANNUNCIATOR PANEL
The warning lights
ALT1
,
ENG
(YELLOW),
ENG
(RED),
P/S HEAT
(optional) and
TEST
(test switch) are incorporated in the annunciator panel.
7.16.1 Warning Light ALT1
The red alternator warning light (
ALT1
) should not illuminate during normal operation.
The warning light illuminates only if:
An alternator failure (
ALT1
produces no current) occurs
In this case the electrical power is supplied solely by the battery.
The ignition system of the engine is independent of the external alternator and is
therefore unaffected.
7.16.2 Warning Light ENG (YELLOW/RED)
The warning light
ENG
(YELLOW) appears as soon as a value in the MVP-50P-AQ
reaches the caution range. The warning is confirmed by pressing the EXIT key and the
light goes out.
The warning light
ENG
(RED) appears if a value falls below or exceeds the operating
limits and cannot be reset.
7.16.3 Warning Light P/S-HEAT
Refer to Section 7.18.1.
