EPSI570 System description
EPSI570 is an integrated avionics device which monitors several propulsion system operational pa-
rameters on the ALPHA Electro. The display informs the user about system status and shows RPM,
power controller temperature, motor temperature, coolant temperature, state of charge (SOC), bat-
tery temperature and state of health (SOH).
EPSI570 device is installed on the instrument panel of the aircraft and is located in the center or star-
board side depending on the panel configuration. The device is composed of a main display, a se-
lection knob, five buttons (only the first one from the top is functional) and a USB port for software
updates.
The device is operative when the AVIONICS switch is engaged. The display is switched off by pressing
the first button, which does not deactivate the system, but just turns the screen off.
Rotation of the selection knob allows the user to move from page to page on the display. Warning
and caution messages are acknowledged by pressing the selection knob. Next message, if present,
will appear.
