In case of short pit access, the reset of the TSD21 safety system also acts as reset of
the pit inspection as required by EN81-20.
In case of only short headroom and normal pit, pit access is same as without TSD21
(Activation of TSD21 lever on top of car is not necessary, reset of the TSD21 system is
also not necessary. See table below), But the reset procedure to exit pit inspection mode
is still the same and must be carried out to leave inspection mode.
The following tables highlight the main shaft access and exit procedure steps required
for proper use of the TSD21 system.
