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.
Coast Controls, manufacturers of All-Air Web Guiding systems, will be featuring a live demonstration unit running clear plastic film through various web guiding systems including a cantilevered unwind, displacement and steering guides with center guiding, splice table, auto centering and finally a new cantilevered rewind system, featuring Montalvo Tension Control components throughout.
Coast will also be discussing their custom turnkey unwind and rewind systems featuring Montalvo tension controls! Let Coast design an Unwind or Rewind guiding system that meets the needs of your application!
