TROUBLE SHOOTING AND TESTING
1.
Apply 24 VAC or 24 VDC to “PWR” terminal, confirm power LED is on and measure voltage to confirm proper voltage.
2.
Check the DIP settings. Depressing the switch closest to the MAN/AUTO pot selects the ON position. You must reset
power if switch changes are made with power on or they will not be recognized.
3.
Testing the output. Connect power. Place MAN/AUTO jumper to Manual.
Voltage Out:
Confirm DIP switch setting for “Voltage Out” (See Figure B, page 1) Should be 7 OFF & 8 ON. With meter only
connected to the SIG and PWR (-), turn the manual pot full left and then full right. The output should vary from
0 to 100% of calibrated or jumper selected range.
If no change is seen, contact ACI Tech Support at (888) 967-5224.
If yes, connect load/device and meter to SIG and PWR (-) terminals. Turn override pot and measure voltage.
Do the readings match the no load test?
If no, check load impedance mismatch or a possible ground loop problem and/or call ACI Tech Support at (888)
967-5224.
IF yes, voltage output is functioning properly.
Current Out:
Confirm DIP Switch setting for “Current Out” (See Figure B). With meter only connected to the SIG and PWR(-)
turn the manual pot full left and then full right. The output should vary from 0 to 100% of the calibrated or
jumper selected range. If not, measure the voltages and turn the Manual override pot clockwise. Is voltage
present? If no, contact ACI Tech Support at (888) 967-5224.
A voltage between 15-39 VDC indicates the AUD is attempting to generate the desired mA. Load or meter may
have an open, blown fuse or connected improperly. A 250 or 500 ohm resistor will also work to test the output.
Connect the resistor to the SIG and PWR(-) terminal. With 250 ohms on the output the voltage from one side of
the resistor to the other will be 1VDC @ 4mA and 5VDC @ 20mA. Using the 500 ohm will give 2 VDC @ 4mA
and 10VDC @ 20mA. Does the unit function as stated above?
If no, contact ACI Tech Support at (888) 967-5224.
If yes, current output is functioning properly.
4.
Testing the input – To manually test the input.
Apply 24 VAC or 24 VDC to the PWR terminal. Connect your meter to the SIG and PWR(-) terminal. Set meter
to match output DIP switch settings. Place MAN/AUTO jumper to AUTO. Connect a jumper wire from UP + to
the PWR(+). Connect a jumper wire to the PWR(-) only. You are now ready to simulate an input pulse signal.
For testing purposes, select the 15 second range (DIP switch 1 ON, DIP switch 2 OFF).
Be sure to reset power to allow the AUD to recognize new settings.
Take the free end of the jumper wire from “PWR”(-) and connect by holding wire to the “UP”(-) terminal. Verify
the pulse LED indication. Read output. Has the output changed? The output should be increasing and stop
when maximum span is reached.
Placing the wires on the DWN + and – terminals should decrease the output signal. If no, change the
TRC/NRM to the opposite setting and repeat test. Has the output changed?
If no, contact ACI Tech Support at (888) 967-5224.
If yes, unit is functioning properly.
