Configurable Inputs
The
configurable
alarm
inputs of the
Smartpack
alarm board can be used to
connect external site alarms
or input devices such as
door sensors, fire alarms,
and generator activation
alarms. Each relay circuit can
be set to “normally-closed” or “normally-open”. This can be selected through
either the menu or the
PowerSuite
interface. Some inputs can be used by
auxiliary system components like external or tray-mounted battery disconnects
and DC-DC converter alarms. Use solid or stranded wire of size 28-16 AWG.
Temperature Probe Terminations
The standard
Smartpack
controller is capable of temperature-compensated
battery charging, symmetry monitoring, and advanced battery discharge
monitoring. Temperature probes can be provided alone or integrated into the
symmetry monitoring cables.
Rear access to the system controller is required in order to connect a single
temperature probe. Unlock the
Smartpack
controller using the same process
used for the rectifiers (see page 12). Feed the cable through the system as
desired through the wiring ports.
The 15-pin serial connector (DE15) of the
temperature probe connects to either
CON3
or
CON4
on the rear of the
Smartpack
controller.
The probe end is designed to be
installed directly at the battery post.
The best termination point may vary
depending on the type of battery
being used. The probe itself is not
polarity sensitive, so it can be
installed at either a (–) or (+) battery
post. The hardware configuration at
left is recommended. This allows the
probe to monitor the temperature
accurately without interfering with
the current-carrying terminations on
the battery.
