Troubleshooting:

If the set up procedure does not achieve the desired results, double check the wiring and perform the

following tests. Record the test results.

Tools required:

A battery operated multi meter and a small screwdriver are required.

Check the power input:

The card will not function correctly unless the +POWER to PWR COM voltage is at least 11 V. If this

voltage is more than 30 V the card may be damaged.

Check the control input you are using:

Potentiometer input:

Measure the wiper voltage between the VOLT and SIG COM terminals. With a 10 K ohm potentiometer,

the wiper will go from 0 (minimum current) to 9 V. The difference in voltage should be more than 5 V from

minimum to maximum. The voltage must not be less than 0 V or more than 10 V.

Voltage input:

The difference in voltage between the VOLT and SIG COM terminals should be greater than 5 V from

minimum to maximum. The voltage must not be less than -5 V or more than +10 V.

Current loop input:

Measure the current into the CUR terminal. The difference in current should be at least 10 mA from

minimum to maximum. The current must not be negative or more 20 mA. If a current meter is not

available, measure the voltage from the CUR terminal to the SIG COM terminal and divide by 150 for an

approximate reading.

NOTE: Only one control input at a time may be connected.

Verify the coil is not shorted:
