≥ 100 ms (Test pulse rate, high test pulse)
≥ 50 ms (Test pulse rate; low test pulse at A1/A2)
max. 1 ms (Test pulse width; high test pulse at A1/A2)
max. 5 ms (in the event of voltage dips at U<sub>s</sub>)
max. 5 ms (Test pulse width; low test pulse at A1/A2)
Test pulse rate = 100 x test pulse width
Test pulse rate = 15 x Test pulse width
