Speed Profiles; Collision Count - Centurion D2 Turbo Installation Manual

21.1.8 . Speed Profiles

The D2 Turbo can be set to run on either a High Speed Mode (default) which is
approximately 24 metres per minute, or a Low Speed Mode which is approximately 16
metres per minute.
High speeds offer a greater level of convenience and security, while slower speeds ensure
increased levels of safety at the gate.
To change the Speed Profile, please refer to the section, 'Customising the Features and
Functions' on page 60.
21.1.9. Anti-crushing Sensitivity
The D2 Turbo incorporates a sensitive electronic anti-crushing technology that responds
in the event that a person or vehicle obstructs your gate.
Using this technology, the typical response
for an opening gate is to immediately stop
and retract a short distance, while a closing
gate will stop and fully reopen.
Collision Sensing can be set to either High
Sensitivity or Low Sensitivity. Generally High
Sensitivity should be used, but in instances
where the gate runs very poorly, for
example if the gate's rail is damaged, Low
Sensitivity can be selected.

21.1.10. Collision Count

A counter monitors the number of collisions that the gate experiences before it fully
closes. If the number exceeds the default value of four, the gate will stop. The Status LED
(page 59) will flash four times every second until a remote control or intercom gate
release pushbutton is pressed.
Please refer to Gate Status Indication (page 59) for more information on this diagnostic
device.
21.1.11. PIRAC – (Beam Autoclose Mode) - optional
PIRAC Mode (Passive Infrared Autoclose) can only be used if a Closing Safety
Beam (page 54) is fitted.
This mode can be used in conjunction with any of the Operating Modes, Standard, Open
Only and Reversing Modes.
