21. Controller features
Menu 2 - Safety (collision force)
Collision force
If the gate is obstructed, the internal collision circuitry will activate. The
response of the system to a collision will vary, depending on the profile
(operating standard, e.g. ZA,) selected. Responses can vary from the gate
stopping, to the gate reversing. The collision force can be set from minimum to
maximum in five discrete steps.
A sixth step will disable collision sensing entirely, allowing maximum force to
be achieved. Under this condition, the motor will continue running until it
stalls, at which point a collision will be detected.
Menu 3 - Autoclose
Autoclose status
When turned on, the
Autoclose
feature has the function of automatically closing
the gate after a preset
Autoclose
time. The
Autoclose
feature is automatically
turned on when the controller is set for
Condominium
Mode of Operation.
Autoclose time
The
Autoclose
time can be set anywhere from 1 to 255 seconds.
This level should only be used if additional safety measures are taken.
(e.g. infrared beams, sensitive edge, etc.). Collision force can be set
independently per direction of travel.
Collision count
A counter monitors the number of collisions that the gate experiences before it
reaches the fully closed position. If the value exceeds the value set in the
multiple collision counter
the controller shuts down until the next valid
trigger is received. As indication, the
status
LED will flash four times every
two seconds. The
multiple collision
fault indication will continue to flash
indefinitely or until a valid trigger has been received.
Alarm output
After the preset collision count has been reached, an alarm is activated. The
system can be configured to operate one of the following outputs provided on
the controller:
Onboard buzzer
– emits a continuous tone
Pillar / Courtesy light contact
(potential-free normally-open contact, fuse
protected – 5A)
Aux IO
(this is an open collector drive, max current draw 3A, not fuse
protected)
Safety beam common
(this is an open collector drive, max current draw
3A, not fuse protected)
Status LED
output
(operate up to three LEDs in parallel or interface with
multi-LED driver card, CP78)
LCK input as ESTOP
Allows the Lck (Holiday Lockout) input to be configured as an emergency stop
input. When activating the emergency stop it will prevent the gate from
moving, and if it is moving, it will immediately stop.
