A bistable RCS is an RCS whose installed control mechanism remains stable in its operating position when it is not electrically excited or mechanically started, but changes its operating position once it is excited or started. 3.111 Monostable RCSmonostableRCS
is an RCS in which the control mechanism changes the operating position of the switch when it is electrically energized or mechanically actuated (the switch maintains this position when the RCS is energized or actuated), and after the energization or actuation of the switch stops, the mechanism returns to the position before the RCS was energized or actuated.

After this test, the RCS shall be able to operate immediately and meet the following conditions: The temperature rise of any part of the RCS housing that can be touched by the standard test finger (GB16915.1 Figure 2) shall not exceed 150K; The temperature rise of the plywood bracket shall not exceed 100K; The RCS shall not emit flames, molten materials, hot particles of insulating materials or burning drops. After cooling to ambient temperature:
The RCS shall be able to withstand the dielectric performance test between the switching circuit and the control circuit specified in Chapter 16. During the test, the test voltage is reduced to 75% of the value specified in Table 13 of GB16915.1—1997. The RCS shall still meet the requirements of 10.1. Then the RCS coil is energized with the rated control voltage for 1h, and the switching circuit is energized with the rated current at the rated voltage. The duration of each operating cycle is 2s, that is, 1s is \ON\ and the other 1s is \OFF". The coil temperature rise is determined by the resistance method, and the temperature rise value shall not exceed the specified value of GB/T 11021. Note: If one sample fails, it is deemed to fail to meet this requirement.1, then the RCS coil is energized with the rated control voltage for 1h, and the switch circuit is energized with the rated current at the rated voltage. The duration of each operation cycle is 2s, that is, 1s is "ON" and the other 1s is "OFF". The coil temperature rise is determined by the resistance method, and the temperature rise value shall not exceed the specified value of GB/T 11021. Note: If one sample fails, it is deemed not to meet this requirement.1, then the RCS coil is energized with the rated control voltage for 1h, and the switch circuit is energized with the rated current at the rated voltage. The duration of each operation cycle is 2s, that is, 1s is "ON" and the other 1s is "OFF". The coil temperature rise is determined by the resistance method, and the temperature rise value shall not exceed the specified value of GB/T 11021. Note: If one sample fails, it is deemed not to meet this requirement.
