ox. 35 ms after the OSSDs are switched on, the device performs the first voltage
test 1. Then, after a half basic response time (40 ms), it performs a second voltage
test 1.
After a further half basic response time of the device there is a shut-down test 2,
120 ms later a further voltage test 3. Then the device performs a shut-down test and a
voltage test alternately at an interval of 120 ms. Pulse duration for the individual tests,
see figure 78, page 131, see figure 79, page 132, see figure 80, page 132.
