or T3). When the relay closes an Aux alarm will be triggered, on the
controller.
In addition, a fourth alarm is available via the black (I-NEG) and white (I-
POS) wires on the output alarm cable. This input will accept either a contact
closure or a voltage between 5Vdc and 60Vdc to trigger an alarm. Connect
voltage to the proper wire based on polarity, and when voltage is applied an
Aux alarm will be triggered. It is not necessary to ground the second wire.
Connecting to the wrong polarity wire will not damage the controller.
When an alarm is detected, the controller will set an AUX ALARM followed
by a string of zeros and ones. See Table 10 for help deciphering the alarm
code.
No setup is required to produce an AUX ALARM. Although, if your system is
equipped with a LAN interface, alarms can be user mapped, to a different
relay, through the web interface using the software utility provided by Valere.
Refer to Application Bulletin 201, "Connecting to the LAN Port", that is
included with a LAN capable controller, for mapping alarms.

Expansion Controller Connection

Use of the EXP port is dependent upon the shelf configuration. Not all
configurations make use of the EXP port. The EXP connection is only used
on systems with an external LVD and/or multiple power shelves, such as the
Integrated Power System. This allows the main system controller (BC-
series) to manage an external LVD and/or a second power shelf with an
EC1000.
Connect the communication cable from the external LVD or EC1000
expansion controller into the mating connector labeled EXP. The controller
will automatically recognize the external LVD or second power shelf and
configure itself automatically. No further setup is required. A second power
shelf will require a rectifier(s) to be installed to be active in the controller
software. See example connection in Figure 3.
