9.6 Connection of External DC Power
The default power configuration for Autroprime is mains power
(230V/110V) and 24V batteries. If mains power not is available, it is
possible to power the system with single or double external 24V DC.
External DC power for Autroprime will not be in accordance with EN54
part 4 unless the external power supply is approved for EN54 part 4.
To enable external 24V power solution for Autroprime, BSA-200A dip
switch S2.3 must be set ON, and connector on J3.1 – J3.3 must be
removed.
When a single 24V DC input is used, it shall be connected to J1.3/J1.4
When a second 24V DC input is available, it shall be connected to
J1.1/J1.2, and dip switch S2.5 must be set in ON position.
Note that there is no monitoring whether external 24 V is connected
on J1.3/J1.4 or J1.1/J1.2 or both. All monitoring related to battery and
fuses F1 and F2 is disabled. Fuses F1 and F2 must be checked
manually at regular time intervals to ensure that the system is working
properly.
Whenever switch S2.3 or S2.5 is changed, the system must be
rebooted to read the new switch settings. When the system has
started, the configuration must be saved and the system restarted.
If there is a conflict between the actual power source and the switch
settings on dipswitch S2.3/S2.5, the fault message “Power source
conflict” will appear.
If there is a conflict between the configuration and the settings on
switch S2.3, the fault message
“Power source config conflict”
will
appear.
Voltage for the external inputs should be a standard 24 VDC within
the range of 22 – 28 VDC. The system will give the user a warning if
the external power is outside system limits.
