2.1 Temperature Probes
Up to three, battery temperature probes (sold separately) may be installed for
battery temperature compensation. Attach the probe (either a ring terminal
or paddle style) to a battery and insert the cable connector end into the
mating end of the probe; connect the other end into the temperature probe
inputs denoted as T1, T2, and T3 from left to right. See DO600000039 –
Temperature Probe Sensor manual for more installation information.
Temperature compensation must be enabled for the system to take
advantage of the temperature probes. See section 7.6 for instructions on
setting up thermal compensation. Assuming thermal compensation is
enabled, the controller will automatically setup itself to monitor temperature
via the external probes.
2.2 Alarm Cable Connection
Six form C alarm relays are available through a connector labeled ALM in
Figure 1. To access these alarms, use the cable (sold separately), that has a
shelf mating connector on one end and bare tinned wire on the other.
Available alarm cables are CA210203104 (10ft), CA210203105 (50ft), and
CA210203106 (100ft). Plug the connector end into the ALM connector on
the controller. As for the non-connectorized end, the alarm cable provides
both normally open (NO) and normally closed (NC) alarms. Therefore
choose the proper alarm polarity and connect it and the common (C) to the
alarming equipment.
Table 2 is a list of alarm contacts and the corresponding color code of the
alarm cable. The alarm names in Table 2 are based on the Valere default
controller with profile number 01 (PN 01). Your profile number may be

different and can be determined by accessing the main menu. The main
menu can be accessed by pressing the MENU button down for 5 seconds.
The controller will then display “WELCOME PN XX”; this is your profile
number. Contact Valere tech support at 1-866-240-6614 for a copy of your
company’s controller settings if different from profile # 01. A relay test can be
used to verify that the alarm cable is connected properly. See section 7.5 for
setting up the relay test.

2.3 Auxiliary Input Alarms
To use the temperature probe input port as an external alarm channel, simply
connect a normally open dry contact relay onto an input cable
(CA210023676) and plug the other end into an available input port (T1, T2,

Page 6 of 47 Version 2.0
DO600000191 November, 2006
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.
2.4 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.

Page 7 of 47 Version 2.0
DO600000191 November, 2006
Figure 3 - Expansion connection
2.5 Remote/Computer Interface
The BC-series controller is available in many different varieties, including
several with remote or computer interfaces. See Table 1 for a list of
controllers and connections available for each type.
For the BC502, with the RS232 connection, refer to DO600000132 – BC502
(RS232) manual for further information on how to connect to and use the
RS232 port. Communication with the BC502 is via a supplied
communication cable (CA210042487).
For the BC1000 and BC1011, with the Ethernet LAN connection, refer to
Application Bulletin 201, “Connecting to the LAN Port” for further information
on how to connect to and use the Ethernet LAN port. Communication with
the LAN port is via an Ethernet cross-over cable or straight through cable a
router. This cable is not supplied by Valere Power.
For the BC1001, with the modem connection, refer to Application Bulletin
202, “Modem User Manual” for further information on how to connect to and
use the modem port. Communication with the modem requires a working
phone line, and a VT100 capable interface.

3Controller Insertion & Setup
Install the controller by sliding the controller into the shelf, tightening the
mounting screw, and attaching the display to the shelf. Once DC power is
applied to the shelf, either by the rectifiers or batteries, the controller will power
up. The controller will automatically recognize all the components in the system
and automatically set itself up. After several seconds the controller will settle to
either SYSTEM OK or SYSTEM ALARM. See section 8 for assistance with any
alarms.
The controller will arrive already setup with the default settings based on the
profile number. No setup is required. These default setpoints can be found in
Table 3. The values in Table 3 are based on the Valere default controller with
profile number 01 (PN 01). Your profile number may be different and can be
determined by accessing the main menu. The main menu can be accessed by
pressing the MENU button down for 5 seconds. The controller will then display
“WELCOME PN XX”; this is your profile number. Contact Valere tech support at
1-866-240-6614 for a copy of your company’s controller settings if different from
profile # 01.
