Commissioning an EBL128

Before you connect any power to EBL128 all other cable
connections shall be made. Check, once more, that the connections
are correct.
A tip! Measure the resistance of each loop wire (L & C respectively)
before turning on the power. Check that the L-wire (SA) that goes out
on terminal J1:1 comes back at terminal J1:3 and so on. If the loop
has short circuit isolators, only the C-wire (SB) can be measured.
Also measure the resistance between the loop wires and 24V, 0V and
Earth (J2:1, 2 and 3). The resistance should be very high (mega ohm).
1. Remove the rectifier (power supply) fuse (F1) on the main board.
2. Remove the battery fuse (F2) on the main board (or the fuse
between the batteries).
3. Connect the batteries to the main board.
4. Connect the rectifier to the mains (230 V AC).
5. Put back the rectifier fuse (F1) on the main board.
6. Put back the battery fuse.
7. LED "Operation" (L6) lit indicates that the 24 V DC power supply
(rectifier and/or battery) is okay.
8. An automatic restart will now take place (see chapter "Restart",
page 77.
9. The site specific data (SSD) is now to be downloaded, see chapter
"SSD programming & download", page 72.
See also chapter "Calibration of supervised outputs (H5/A1)", page
112.

Regarding especially the previous main board 4556 (P.c.b. No.
9285-5A): If a lot of units (especially units with high internal
capacitance) are connected to EBL128, the total momentary inrush
current consumption might activate the electronic short circuit
protection and EBL128 will not start working. In such a case, put
back the battery fuse before the rectifier fuse (i.e. the batteries have to
be reasonably charged) or temporarily disconnect some of the units in
order to reduce the current consumption while EBL128 is powered.
