Troubleshooting Tip: No Response from the Amplifier on Your Controller
BWC Blog

1. Always check to make sure the proper power is being supplied to the amplifier. For example our A4 Amplifier requires 24 VDC input whereas a M3200 utilizes 120/240 VAC. If the wrong voltage is supplied to the amplifier, the amplifier will not work and could potentially permanently damage the amplifier.

2. Ensure the output signal wires of the amplifier are connected properly. Please check your amplifier manual for proper signal wire connections. Your controller or PLC will expect either a +4-20mA or +0-10VDC, and thus the proper signal connection must be made. Make sure you connect EITHER the +4-20mA or the +0-10VDC (or both) depending on the requirements of your control method.

3. If you have correctly checked the first two items, the next step is to ensure proper installation of your load cells, which will vary depending on the type of load cell you are utilizing.

If you are still experiencing issues, or need any other additional assistance, please contact a Montalvo Applications Specialist.
