If the authorisation signal enabling transit in direction ‘A’ is received from the reader unit,
rotation will be released in that direction (‘A’ energised in FL – de-energised in FS)
To lock the Hercules-Lite Tripod on completion of rotation, the locking arm is recalled (‘A’ de-
energised in FL or energised in FS) when the Hercules-Lite Tripod has rotated approximately
67
O
from the starting point.
During the entire rotation solenoid ‘B’ remains de-energised in FL configuration (energised in
FS) in order to perform the anti-reversal function.
The system operates in the same manner for transit in direction ‘B’.
Normally Open Transit Sequence
At rest, rotation is not prevented by the solenoids that are energised in the FL configuration (de-
energised in FS)
If a person attempts to rotate the Hercules-Lite Tripod in direction ‘A’ without authorisation
having been received from the reader unit – solenoid A will lock the Hercules-Lite Tripod after it
has rotated approximately 10
O
. Only when the Hercules-Lite Tripod has returned to the
BARRIER position will the rocker arm release.
Note - The same action applies for direction ‘B’.
During transit in any direction, if an attempt is made to reverse the Hercules-Lite Tripod the anti-
reversal device will only intervene if the Hercules-Lite Tripod has already completed a rotation
of 67
0
in the authorised direction.
The anti-reversal device operates when the control logic detects a rotation of approximately
3.3
O
in the opposite direction to that authorised. Solenoid ‘B’ will operate if the authorised
direction is ‘A’ or vice-versa. The solenoid releases the rocker arm only when the Hercules-Lite
Tripod is rotated a further 6.6
O
in the authorised direction.
Emergency / Fire Alarm
The Hercules-Lite turnstile offers an input (normally closed) in order to receive an Emergency /
Fire Alarm remote command (by other).
When this command is active, the control logic releases the rotation of the tripod in both
directions. This condition will remain for the duration of the signal being received by the control
logic.
If the turnstile is equipped of optional drop arm device, when the command is active, the arm in
the barrier position is released in order to leave the passageway open.
Connection details are given in Section 5 of this manual.
Traffic Lights and Pictograms
In order to facilitate the transit flow, optional traffic lights and pictograms are available which
show when a turnstile is programmed with the lock mode or is already engaged in the other
direction (red cross). Similarly the presence of a green arrow indicates that a user can pass
through the turnstile. In case of pictogram, an additional card reader sign indicates that the
entrance is ready to accept the access control system authorization.
If this optional are used, a trimmer of the LL2001 electronic board must be properly configured
(see Section 8 – table 8.5).
