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.
