Deactivation of TSD21 Safety System
– Open the landing door that gives access to the car roof
– Press the top of car stop button (JHC)
– Retract/fold the balustrade, if any
– Deactivate the TSD21 lever
– Exit the top of car
– Release the top of car stop switch (JHC) only after having exited the car roof
– Close the landing door giving access to the car roof.
Reset of TSD21
The reset of the safety system is only possible by pressing the reset button (DRZS)
which is located in the control cabinet.
– Check all stopping devices have been released and all landing doors are closed and
locked (with the help of HMI command 162, the controller will send a lock command
to any door available in the system. This will help to close the safety chain in the
TSD21 hardware exit procedure)
– Unlock and press DRZS button on SMICHMI to reset TSD21 system
– LED LZS (RD) shall be turned off when the reset is succeeded
– Relock the DRZS button.
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), But the reset procedure to exit pit inspection mode is still the same
and must be carried out to leave inspection mode.
