Overview
OV1. Physical Description
OV1.1 Basic System
The basic CR9000X system includes a CR9011 Power supply module, a
CR9032 CPU module, and a CR9041 A/D module. These are installed into a
mother board in an enclosure. Also included in all CR9000X base systems is a
battery, and a wall charger.
There are two sizes of base systems to choose from. The CR9000XC compact
version comes in an aluminum enclosure and can accommodate up to 5
measurement modules. The CR9000X full size chassis can be configured with
a lab enclosure or a fiberglass environmental enclosure and can accommodate
up to 9 measurement modules.
The CR9000XC includes a 7 AHr lithium battery. The CR9000X full size
logger includes two 7 AHr batteries. It is recommended to keep these
batteries from reaching a state of deep discharge (10.5 V) which can damage
the cells.

FIGURE OV1-4. CR9011
The CR9011 Power Supply Module provides regulated power to the CR9000X
from either the internal battery modules or from the 9 to 18 VDC (fuse and
diode protected) charge inputs. It also regulates battery charging (up to 2
amps) from power supplied by the AC adapter, a DC input, or other external
sources. The AC adapter may be used where AC power is available (100 - 240
volts) to provide power to the CR9000X and charge its batteries.
High Current Demand Applications
A DC source with voltage in the range of 9 to 18 VDC will charge the internal
lead acid batteries and power the CR9000X provided sufficient current is
available and the system is set-up to use 3 amps or less. If the CR9000X
system configuration requires greater than 3 amps, consult a CSI applications
engineer for information about the CR9011 Power Supply High-Current
modification.
LEDs There are 2 LEDs: Power and Charge. The Power LED is red if
the logger is powered up. The Charge LED is red to indicate the
presence of a charging source for the batteries.
On/Off The ON/Off toggle switch is used to manually power up and down
the logger. It should be noted that if the toggle switch is in the ON
position, but the Power LED is dark, it could either mean that there
