On the Outside
Easy Inside Access
A pair of thumbscrews are used to remove the top cover. The user can then access the Limit Value adjustment and test points.
Current LED
This LED illuminates when the charging current is in excess of 1Amp. This condition indicates that the charger is operating properly as it is restoring depleted charge to the battery.
Alarm LED
This LED illuminates when a failure is detected. A failure is defined by the simultaneous occurrence of two conditions. The monitored battery voltage is less than its adjusted Limit Value and the charger is failing to provide a charging current of at least 1Amp.
Voltage LED
This LED illuminates when the monitored voltage exceeds the adjusted Limit Value and is therefore considered acceptable.
Relay Output
Normally open and normally closed relay contacts are provided. Along with the Alarm LED they are used to distinguish nominal operation from a failure condition.
BN Power
Typical battery power can be monitored and used to power the device. Its operating range is 8 to 40Vdc. BN power terminals are fully isolated from the chassis and outputs.
Detachable Connectors
The Relay Output and power connectors are detachable for ease of installation. Screw-down connectors are used throughout.
Small Mounting Footprint
The device can be mounted on a shelf or backboard. It can be mounted in any convenient orientation.
CSI‑1 Documentation
On the Inside
User Adjustable Limit Value
The Limit Value is adjusted by rotating a 20-turn potentiometer. The adjustment range is 10 to 30Vdc.
Test Points for Voltage Limit Value
A Digital Voltmeter is connected to the Test Points. The Limit Value is set by adjusting the DVM measurement. The ratio of effective Limit Value to measured Vdc is 10 to 1.
Current Limit Value is Fixed
The Limit Value for the charging current is set at the factory to 1Amp.
Fully Compatible with any Event Recorder
The Relay Output contacts are dry. They can be connected to any MICRO‑AIDE CWR or CAR product or non-MICRO‑AIDE product.
Designed to Operate in Harsh Rail Applications
Like most MICRO‑AIDE rail products the device will operate in ambient temperatures of -40C to +72C.
