Range of Robot Modules

For Use with the Trallfa Robot A/S

Maintenance Recommendations

1. Voltage Measurement: Measure the output voltage ripple every six months to ensure it remains within acceptable limits.

2. Tighten Wiring: High-current terminals are prone to loosening due to thermal expansion and contraction; tighten them regularly.

3. Dust Removal: Power modules easily accumulate dust; clean them periodically with the power off using dry compressed air.

FAQ

Q: Is it normal if one of the two power LEDs on the PCU-03 module is on while the other is off?
A: No, it is not normal. In a redundant dual-power configuration, both LEDs should be on. If one is off, it indicates that one power input is missing or that the internal fuse for that channel has failed.

Q: Can the PCU-03 be directly cascaded with PCD231/PCD232 modules?
A: Yes. In an AC 800PEC system, the PCU-03 is typically installed on the far left of the rack and provides backplane power to PCD modules.

Q: Why does the PCU-03 module produce a faint buzzing sound during operation?
A: It may be caused by physical vibration of internal inductors or transformers operating at high frequency. If the noise increases significantly or is accompanied by a burning smell, the system should be shut down immediately and the module replaced.

Q: Can a standard 24V industrial switching power supply be used instead of the PCU-03?
A: No, replacement is strictly prohibited. The PCU-03 includes specialized filtering and multiple isolated outputs, and standard power supplies cannot provide the same level of noise immunity and protection.

Q: What is the recommended replacement cycle for the PCU-03 module?
A: Considering the lifespan of electrolytic capacitors, preventive replacement is recommended after 8–10 years of continuous operation.
