Troubleshooting KUKA Sunrise Cabinet Med

It should be emphasized that security features cannot be bypassed. If the safety door automatically resumes operation after being closed, it may pose a risk of personnel still being in the danger zone. The operation safety signal must be reset by an additional confirmation device, and cannot be restored to automatic mode solely by closing the safety door.

Installation, power supply, and electrical planning

KUKA Sunrise Cabinet Med can be installed in a 19 inch rack or as a standalone device. The rack depth must be at least 600 mm. During installation, a 70 mm cooling air gap must be maintained on both sides. When installed vertically, the fan opening and ventilation duct cannot face upwards and must be fixed with screws. The protection level is IP20, suitable for environments with a pollution level of 2; If the pollution level is 3, an additional IPX4 enclosure is required.

In terms of power supply, the controller can only be connected to a power system with a neutral grounding point. The rated voltage is 110 V/230 V AC, single-phase, allowing ± 10% fluctuation, with a frequency of 50 Hz ± 1 Hz or 60 Hz ± 1 Hz. The rated power is about 1 kVA, and the maximum heat dissipation is about 370 W. The power side fuse is 2 × 16 A slow melting, and the equipment side is 2 × 10 A slow melting. PE equipotential connection must be reliable.

If residual current circuit breakers are used, it is recommended to use 300 mA universal current sensitive type for each controller. The power connection can be completed through cables with or without main connectors. When connecting, it is necessary to confirm that the green/yellow wire is connected to the PE, the light blue wire is connected to the neutral wire, and the black wire is connected to the phase wire. All connections must be made in a power-off state.

Pay attention to condensation before starting. If the temperature inside the control cabinet differs greatly from the ambient temperature, condensation may form. Should wait for temperature equilibrium. Before the first startup, it is necessary to insert the X305 connector into the CCU_SR to release the battery discharge protection. After inserting the smartPAD into X19, if the smartPAD is disconnected, an emergency stop will be triggered. Therefore, if medical devices allow smartPAD to be pluggable, an external emergency stop device that is always accessible must be installed.

In terms of EMC, the controller complies with Class B, Group 1 of EN 55011. To meet system level EMC requirements, robots must be connected to PE equipotential conductors. If connected to smartPAD-2, it may not achieve Class B emissions and may cause radio interference during residential use.

Key points for preventive maintenance and replacement

The maintenance of KUKA Sunrise Cabinet Med must be carried out on a periodic basis, and the controller must be turned off, power disconnected, locked, and tagged before maintenance to prevent unauthorized re powering. ESD protection must run through all board and electronic component operations.

The recommended maintenance cycle includes:

Check the relay output function of CCU_SR that has been used annually. Default output 12 is local emergency stop, output 13 is test mode, and output 14 is automatic mode. The contact status can be checked by triggering the corresponding function.

Clean and protect the grille and fan with a brush every year based on the installation environment and pollution level.

Replace the motherboard battery every 5 years.

Replace the fan every 5 years during the three shift operation.

The battery should be replaced according to the monitoring display, at the latest every 2 years.

When storing the battery, if the temperature is ≤ 20 ° C, charge it every 9 months; 20-30 ° C every 6 months; 30-40 ° C every 3 months. Otherwise, it may be damaged due to deep discharge.

When replacing the motherboard battery, first open the outer shell, unlock the lithium button battery fixing mechanism, remove the old battery, install the new battery, and clip it into the locking mechanism. When replacing a hard drive, first unplug the power and data cables, remove the fixing screws, install a new hard drive, and then reconnect it. When replacing the battery block, both must be replaced together. Remove the battery connection cable and connect G3.2 and G3.1 according to the label. When replacing the fan, remove the fixing screws of the fan bracket, unplug the fan connector, and be careful not to confuse the motherboard CPU fan connector.

Visual inspection must be conducted after maintenance to ensure that fuses, contactors, plugs, and boards are securely fastened; Whether the cable is damaged; Is the PE equipotential reliable; Are all system components worn or damaged. The safety functions must be retested, including emergency stop, enable switch, mode selection switch, safety output shutdown capability, etc.

CCU_SR LED and common troubleshooting

The LED on CCU_SR is the first entry point for fault location. The common states are as follows:

PHY4, SW-P0 green: off indicates a fault, usually requiring replacement of CCU_SR module; Lighting up or flashing indicates normal operation.
