Why does the ZS not react to the light button or only unreliably?

The push-button input can no longer be activated reliably if the maximum permissible line capacitance is exceeded and/or the glow lamp load is too high. The resultant current flow will then cause an undesirable permanent activation of the input. However, these currents can be discharged again by using a suitable system capacitance (e.g. NC 41). The maximum permissible line capacitance and/or glow lamp load can then be increased several times if necessary.
