Because the QV60-RGC1 is a component sold to OEMs and installers, it rarely comes with a standalone "user manual" in the box. Instead, the technical specifications and wiring diagrams are integrated into the of the boiler it is attached to.
This ensures precise control of key process variables like hydraulic pressure and flow, which is critical for applications requiring high repeatability. This card is most commonly found as a core component in from manufacturers like Chen Hsong, Haitian, and others, where it governs the molding process with high precision.

Measure the compressor running amps with a clamp meter to ensure it matches the data plate specification. 6. Troubleshooting and Error Codes
Route the power cable through the PG gland on the bottom right of the chassis.
(often categorized under part number ) is a legacy high-performance, analog proportional valve amplifier card engineered by Bosch (now Bosch Rexroth ). Designed primarily for industrial hydraulics, this Eurocard-format amplifier regulates solenoid-actuated proportional throttle and directional control valves with electrical position feedback. Because the QV60-RGC1 is a component sold to
The Bosch QV60-RGC1 is a compact, feature-focused quartz oven/grill (QV) model designed for small kitchens, apartments, and as a secondary cooking appliance. It blends straightforward controls with reliable Bosch build quality, targeting users who want fast grilling, toasting, and small-batch baking without a full-sized oven.
| Symptom | Possible Cause | Suggested Action | | :--- | :--- | :--- | | | Supply voltage is too low or missing. | Measure the 24 VDC supply at the card's terminals. Ensure it's stable and within specified range. | | Yellow LED is ON | A "Cable Break" is detected or the "Ramp" is disabled. | Check the wiring to the valve solenoid for continuity. Ensure there is an enable signal (8.5–40 V). | | No output from the card | Enable signal (8.5–40 V) not present. | Verify that the machine's PLC is sending the correct enable signal to the designated terminal. | | Actuator moves when it shouldn't | Incorrect zero point (null) calibration. | Re-adjust the "Nullpunkt" potentiometer with the command signal at 0V. | | Actuator moves, but slowly or erratically | Weak command signal or incorrect gain. | Measure the command signal voltage. Re-adjust the "Empfindlichkeit" potentiometer. | | Card is suspected faulty (after initial checks) | Internal electronic component failure. | Do not attempt repair. This is a multilayer PCB; professional replacement or repair is recommended. |
