Section 16.0 Application Notes
16.10 - Programming of the Automatic Periodic Test (example: 20 minutes every 7 days)
A) -
Enter the 'Program Mode' and set [P.41] to [168] hours (168 hours=7days).
B) -
Set [P.42] to [ 20'] and save the programming
C) -
Select the AUTO mode
D) -
Disconnect the battery and wait for the desired start time (using an external clock reference).
E) -
Connect the battery and select the 'AUTO' mode.
The Be242 will start the engine after the programmed hours. The engine will run OFF-LOAD for 20 minutes. If
the Mains fails during the automatic periodic test, the Be242 will transfer the load to the generator.
The Be242 does not use an internal real time clock for the programmed hours ([P.41] setting, table 7.05). The
user could experiment with shifting the periodic tests (about some minutes a month). To avoid error
accumulation, we recommend the following procedures
(D)
and
(E)
as indicated in section 16.10.
IMPORTANT NOTICE If the Vdc voltage supply is removed, the Be242 loses count of the days. When the
supply restores, the Be242 starts to count the A.P.T. from zero. To synchronize the periodic start follow the
above instructions
(D)
&
(E)
.
16.20 - Interfacing an Auto start with Be242 A.T.S Controller
To use the Be242 as an A.T.S. controller, follow the wiring diagram of the section 17.0. If the engine running
output from the AUTOSTART is not available, program the [P.26] to [oFF]. We recommend that you program the
[P.31] to [15] (number of attempts) in order to provide proper time for AUTOSTART to start the engine.
16.30 - Single Phase operation
Program the parameter [P.8] with the option
‘3’ as indicated in section 7.01B. Connect the Mains LIVE (phase) to
terminals ‘S’ and ‘T’. Connect the NEUTRAL to terminal ‘R’. Connect the Generator LIVE (phase) to terminals
‘L2’ and ‘L3’. Connect the Neutral to ‘L1’. In this way, the outputs KM and KG will output a ‘phase’. This will allow
to energize the coils of the contactors (supposing to connect the other side of the coils as indicated in section
18).
Connect the current transformer to terminals ‘COM’ and ‘CT1’. Finally, adjust the parameters P4, P5, P9
and P10 (Over/Under Voltage settings) according to your needs.
16.40 - Maintenance & Rental Timers
Once a timer expires, the Be242 indicates the [Er.10] on display. To clear the alarm(s), enter the manual mode,
push and hold the [ACK-F10] button for at least 20 seconds. You are allowed to modify the programmed
Maintenance timer at anytime. Programmable timers are described in section 7, table 7.05A-B (P44, P45 and
P46). To restart the Rental Timer, you are required to enter the programming and exit the programming (we
recommend that you limit the access to the programming by using a password).

17.00 - Interfacing Auto Start Module
You may use the FUEL SOLENOID output relay JA2. You may use RUN PLUS input as feedback. You are in
some cases required to increase the attempt numbers to let a reasonable time to the AUTO START module to
start the engine, When FUEL SOLENOID shuts down, the AUTO START module will stop the engine.
