Safety Monitoring Device
The Safety Monitoring Device is integrated in the FST-2 circuit board (K20
.. K23) and enables car movements in the door zone with open car and
shaft doors. This makes approaching and relevelling with open doors
possible.
The Safety Monitoring Device requires two solenoid switches on the
car roof (zone A (S27) and zone B (S28)).
The Safety Monitoring Device can only be activated and commissioned if
these two solenoid switches including solenoids are installed and
connected (see Installation & Commissioning manual).
If the two functions “Relevelling with open doors” and “Approaching with
open doors” are not required, the Safety Monitoring Device is not activated
and the solenoid switches zone A & B are not required.
The Safety Monitoring Device can be activated in the FST menu with the
following parameters, if the zone switches A & B are installed and
connected:
MAIN MENU - Doors - Doors Basic - Pre-Opening
= YES
MAIN MENU - Drive - Relevelling = YES
Operating principle
The relays K20, K21, K22 and K23 are released in the initial state.
If the car approaches the target floor, K21 (zone enabling) is activated by
the controller.
If the car reaches the door zone, the solenoid switches of zone A (S27) and
zone B (S28) trigger and activate the two relays K22 and K23. The relays
K22 and K23 issue the zone message to the controller (car is in door zone).
After the control software received the zone message, bypass relay K20 is
activated if required, this will make K21 release. This relay state (K20
activated, K21 released, K22 activated, K23 activated) bridges the door
contacts in the safety circuit and allows drive movement with the doors
open.
Checking the Safety
Monitoring Device
The Safety Monitoring Device is designed so that malfunction of the two
solenoid switches is detected and results in a system shutdown.
The two following error states must be checked after commissioning the
Safety Monitoring Device:
-
Zone switch A (S27) is permanently open (disconnect FST X13.11)
-
Zone switch A (S27) is permanently closed (bridge FST X13.11 with
FST X1.24)
