Maintenance
- Routine inspection: Check housing seal, LCD display, sensor cable and PROFIBUS connection every 6–12 months
- Clean front cover with soft cloth; avoid strong solvent which may damage the membrane keypad and seal
- ESD protection must be adopted during disassembly, anti-static wristband required
- If tension reading abnormal or fieldbus communication loss occurs, power off and inspect load cell wiring and cable shielding
- Do not energize the unit if seal damage, water ingress or housing corrosion is found
- We support function testing, refurbishment and spare replacement service for this -65 tension electronics unit
Installation
- Cut off 24VDC / AC auxiliary power supply before installation or replacement.
- Wear anti-static wristband to prevent electrostatic damage to internal measurement circuit.
- Mount -65 firmly on machine frame, keep the housing seal intact.
- Connect two Pressductor load cell cables to sensor terminals, connect power cable and PROFIBUS DP bus cable, properly ground cable shielding.
- Power on, enter setup menu, perform load cell calibration, set unit, range and PROFIBUS address.
- Check all wiring and confirm no loose connections.
- Verify tension reading on LCD display.
- Test analog output and PROFIBUS data transmission, validate closed-loop tension control performance and complete commissioning.
