VPS-210 Operating Instructions

This document describes the use and operation of the VPS-210 battery pack.

Packing List

The VPS-210 battery pack consists of the following items:

• Battery Pack

• Battery Pack Carrying Case

• 6 inch Power Cable

Description

The VPS-210 battery pack is designed to provide portable DC power to the VDC-200 Compact Data
Controller. It uses 12 standard “AA” batteries.

Operation

The battery pack is not rechargeable, however it may be used with rechargeable batteries (e.g. NiCad) if
they are charged outside of the battery pack

Never connect the battery pack to a DC power supply.

To prevent accidental connection of the battery pack to a DC power supply, the battery pack uses a different
size power jack than the CDC. The battery pack cable polarized for this reason. Because of this, the only
one end of the cable will plug in to the battery pack.

Be sure that the CDC is turned "OFF" before connecting the battery pack. Use the CDC's built-in-test
(BIT) mode to verify that the two are properly connected that the CDC is receiving sufficient power.

The battery pack is supplied with a Velcro carrying case. Use the carrying case to secure the CDC and
battery pack in a "belly-to-belly" configuration. The carrying case's two elastic bands hold the CDC and
battery pack, then fold the ensemble and secure the Velcro fastener. Any excess length of power cable
should be wedged between the units to avoid accidental disconnection which could occur if the power cable
is left dangling.

For convenience, use the carrying case's built-in pocket to store the power cable when not in use. Note: the
case will also Velcro to the battery pack alone for storage.

with a suitable charging device.

Maintenance

Batteries should be replaced before they are completely depleted to prevent battery leakage and damage to
the battery pack. A battery pack voltage of less than 12V indicates that the batteries should be replaced.

Battery Replacement

To install new batteries or replace used batteries, remove the front panel by loosening the 4 captive screws.
Replace all 12 batteries, at once. Load the new batteries “head-to-tail”, oriented as silk-screened on the top
of the battery pack chassis. When re-installing the front cover, an alignment pin locates the proper
orientation of the cover. Be sure to dispose of used batteries according to battery manufacturer's
instructions.

The table below lists expected battery pack performance with various off-the-shelf battery types. Actual
battery life in your application will depend on many factors, including: which batteries you use, ambient
temperature, CDC active/standby duty cycle, shelf time, etc.

Mixing battery types is not recommended.

Battery Type Cell Voltage Cell Capacity Nominal Battery Life
NiCad 1.2V 600 mAh 2 to 3 hours
Alkaline 1.5V 2100 mAh 6 to 10 hours
Lithium 1.5V * 2250 mAh 7 to 11 hours

* Battery pack voltage ( which equals 12 times the cell voltage) must not exceed 32V or damage to the
CDC may occur. Therefore, 3.0V lithium batteries should not be used.
