4.2.4 Breaker Labelling
For systems with load only outputs, the numbering goes from left (1) to right ( 21 for a 19" or 26 for a 23")
For systems with batteries and loads the load numbering goes from left (1) to center/right (16 for a 19" or 21 for a 23")
AND the battery labelling goes from right (1) to left (5).
There is a label on top of the front door which can be seen from the top when the door is closed, and from the front
when the door is open. This label is larger and suitable for writing information about the breaker position.
There are two additional labels for breaker identification: a thin label above the breaker which can be read from the
front (not writable), and one on the back/top near the return breakers which identify the positions of the return (not
writable).

4.4.5 Alarm and Control Output Relays
The controller contains 12 Form C digital alarm output relays, that are used to extend alarms and control to external
apparatus. Each internally generated alarm or control signal may be mapped to any one of these relays, or several
signals may be mapped to just one relay or none at all. None of the output relays are pre-configured on the (K1-K12)
are available for customer use.

4.4.6 Network Connection and Remote Communication
A CAN bus is used to transmit all alarm and control functions between the L-ADIO and a remotely located CXC HP
controller.
4.4.7 Network Connection and Remote Communications
The Cordex system can be set up, monitored, and tested via an Ethernet 10/100 Base-T serial data connection. The
communication protocol supports a web interface. A CAN bus is used to transmit all alarm and control functions
between the controller and rectifiers.
Refer to CXC-HP Software Manual (0350058-J0) for operation of controller.
4.4.8 Front Panel Wiring Notes
The terminal blocks on the Indicator Boards are suitable for #26-16AWG wire. As both signals are low current, it is
recommend to use thinner wire were possible to make routing easier and to minimize space consumed by in the
system. This is especially important with the L-ADIO if many of the expansion I/O capabilities are to be used.
Added wiring should be routed along the same path as the bus connection cable and then extend through the back
of the unit. Take care to restrain the wiring sufficiently while providing enough slack so as not to interfere with opera-
tion of the door. Use the cable tie locations on the L-ADIO to restrain the cables within the front panel, and use the
lance features on the chassis side panels to guide the cabling to the back of the unit.

4.7 LVD Override
For systems with LVBD an over-ride interface is provided, see Figure 12. This interface board includes 3 LEDs indica-
tors to provide visual status indication, and two customer connections for remote control/monitoring:
LEDs
• BUS (Green) Lit when the bus connected to the LVD has power connected.
• COIL (Green) Lit when the LVD coil is energized. This requires the BUS to have power and one of the controls
(L-ADIO, REMOTE, or LVD Over-ride) to be active
• O/R (Yellow) Lit when the override switch is in the over-ride position. This should only be on during maintenance.
Connections
• OVERRIDE 48V/5mA signal, active when over-ride switch is in over-ride position.
» COIL CTRL Control input for LVBD coil, can be configured for remote control or remote disable:
When configured for remote control (default), a dry contact connected to the coil control input can turn
on the LVBD independently of the LVD or the automatic control.
» When configured for remote disable, the coil control input must be shorted by a dry contact for either
the automatic control or the LVD override to operate.
The LVBD override interface is configured for remote control by default for most systems.

To change configuration:
This operation must be done with AC and DC power disconnected, ideally prior to commissioning the system.
1. Remove the interface from the E3 by removing the two (2) screws from the front
2. Lower the board, and pull it forward through the opening.
3. Flip the board over, and observe the jumper on the bottom of the board.
4. Move the jumper to the desired position:
» CTRL (NO) position: the COIL CTRL is configured for remote control
» ENBL (NC), COIL CTRL for remote enable.
5. After the jumper is set check all cable connections (in case they were pulled loose when the board was
removed)
6. Reinstall the board and labels using the original screws.
