I07A ANTS-SAFE instruction for ANTS-ASA2-ASE:
The ANTSSAFE shaft copying system with the ANTS-ASA2-ASE evaluation unit is a safe position evaluation according to SIL-3
for implementing the functions of limit switches, inspection limit switches, deceleration limit switches, Unintended Car Movement
(UCM) as well as for safe bridging of the safety circuit in the area of the doors in the event of premature failure door opening /
retrieval of elevator systems according to EN81-20. The complete system consists of two devices, the ANTS-SAFE encoder and
the ANTS-SAFE evaluation unit (ASA2) described here. In contrast to a conventional shaft copying with safety limit switches, as
well as redundant zone switches with a safety circuit for door bridging, safe-copying no longer exists! The position detection takes
place exclusively via a coded band, as well as a redundant evaluation unit. Thus, it is not possible to test non-existent switches!
In a learning sequence, the positions of the limit switches and the floors must be taught-in. Thereafter, the taught-in limit switch
positions and the zones around the taught-in levels are emulated. The functioning of the emulated switches is not tested, since
the safe system (SIL-3) already performs all self-tests

Checking the opening of the safety circuit:
To ensure that an ANTS-SAFE fault actually opens the safety
circuit, the XTS connector can be disconnected at the ANTS-
ASA-2-ASE evaluation unit.
As a result, the safety circuit of the elevator control is in-
terrupted. This can be visually checked on the D613, all
LEDs of the safety circuit from U8 must now light up red.

Checking the limit switches above:
The limit switch position can be approached in the D613 control
via the "C410 limit switch travel up" menu.
When passing this position, the safety circuit on the
ANTS-ASA2-ASE is opened at connector X5. At the
D613 control, all LEDs of the safety circuit now light up
red starting at U8. At the same time an error entry ap-
pears in the control.

Checking the limit switches below :
In the D613 control, the limit switch position can be approached
via the "C411 limit switch travel down" menu.
When passing this position, the safety circuit on the
ANTS-ASA2-ASE is opened at connector X5. At the
D613 control, all LEDs of the safety circuit now light up
red starting at U8. At the same time an error entry ap-

Check the zone switch:
First of all, in menu D9 floors ANTSSAFE: xy "/" floors D613: xy
"it can be checked that the ANTSSAFE and the D613 control
board have learned the same number of floors.
The zone areas can be identified on the D613 using the
two green ZONE LEDs. Only in the area of the zones
around the respective floors may these LEDs light up. The
zone information is from the ANTS ASA2 ASE.

The function of the door override can be checked by activating in
the menu "B16 retraction with open door". When traveling up to
the floor, the door lock is activated only in the zone area, which is
indicated by the rapid flashing of the LED "Drive O.T in the D613.
independently and permanently and thus, e.g. the permitted door
lockout complies with the standards.
In addition (OPTIONAL ), the function "C416 Test UCM
zone travel" can be checked on every floor so that the
UCM case is triggered when leaving the zone when door
lock is activated.
