Mounting the Regulator

The regulator is protected against ambient humidity, but must be mounted in a dry location free of moisture, dust, and other environmental insults. The regulator will operate in temperatures to 60$^\circ $C (140$^\circ $F).

Wiring Diagram

The wiring diagram above for one house bank, or at the bottom for a dual house bank, is the only way to wire the Eliminator Do not wire it in any other way, such as combining ground wires or battery positive wires. For safety purposes, always use fuses where shown.

Signal Names and Functions

Battery voltage set-points are specified for each voltage system, 12 or 24 volts, as 12 / 24 volts, respectively.

NOTE: There are two terminal blocks on the Elimintor, TB1, and TB2. Orient the unit so that TB1 is on you left when viewed from the top. Pins are referred to as TB1-X or TB2-X, where X is a number from one to ten. With the Eliminator oriented as above, Pin 1 is at the top of the terminal blocks.

Error Indicator

The green Error Indicator and the external LAMP, TB2-9, if wired, reports abnormal conditions. Errors are identified by On and Off times of the Error Indicator as shown in Table 1 below.

Table 1. Error Indicator
Error On Off
Bat. Volts disconnected 3 1
Bad Temperature Sensor 6 6
Over Temperature 3 3

What You Should See

The regulator is on whenever power is present at TB1-7.

When the regulator is first turned on the green Error Indicator will glow for 5 - 8 seconds before extinguishing. If there is a positive voltage on the ON / OFF input, then the output battery should start to charge after the Error Indicator goes off. Note that the input battery must be at a higher voltage than the output battery for charging to occur. To see the charging process better, make sure that the voltage on the input battery is above 13.6 Volts prior to testing.

Troubleshooting

First, look at the Signal Names and Functions section above and make sure that all required wires are in place and properly connected. To help diagnose voltage set-points, remove the T+ (RED) connection to disable temperature compensation and prevent a faulty temperature sensor from affecting the system.

NOTE: With temperature sensing, a higher battery temperature will result in a lower battery voltage. Likewise, a lower battery temperature will result in a higher battery voltage.

Second, if the problem still exists, obtain a copy of the Eliminator Troubleshooting Guide which is available from the following sources:
Regulator Service Center

The troubleshooting guide was designed to help isolate a majority of the installation problems. Fill out the Troubleshooting Guide to determine if all measurements meet the specified requirements.

Finally, if you are unable to remedy the problem, contact the regulator service center with the Eliminator Troubleshooting Guide completed for referencing.
