Reliability Checks
The reliability checks
are to reduce unforeseen failures to a minimum. If conducted regularly, there is a high probability to detect any defects of the MR instrument in an early phase.
Different operating conditions (e. g. different temperature, size of dust particles, humidity, gases, and vapor) may require shortening the suggested time intervals.

Primary water for Heat exchanger (DLHE) | - ▪
- Check primary water inflow, pressure, and water quality.
| |
| - ▪
- Refill water, potentially clean tank.
- ▪
- Check temperature setting 18 ± 1 °C.
- ▪
- Check secondary water flow to gradient coil
> 2 l/min (B-GA 6S-100),
> 7 l/min (B-GA9S HP),
> 7 l/min (B-GA105S HP),
> 17 l/min (B-GA12S HP),
> 19 l/min (B-GA20S HP),
potentially clean gradient cooling water filter.

Air filters in cabinet doors and instrument cover where applicable. | | |
Ventilators in electronics (RF power supply, gradient power supply, …) | - ▪
- Check functionality and operating noise of ventilators.
| |
| - ▪
- Visual check of integrity of refrigerator lines, compressor, cold head for condensate or ice formation.
| |
| - ▪
- Check the RF sealing and replace if broken or missing.
- ▪
- Clean surfaces contacting the RF sealing.
| |
| - ▪
- Visual check of the wire and mechanics of the ATS cover.
| |
| - ▪
- Check disc space.
- ▪
- Save and archive configuration.
- ▪
- Create and archive backup software image.
