CAUTION :
If HIGHWAY does not assemble the hub with automatic reset, remove relay 1 and
2. The boom uncoupling limit switch is therefore not present, make a link between
terminals 24 and 26.
OPENING BUTTON
Allows opening with the barrier is closed.
During the closing, when pressed, it immediately reverses the opening movement.
This entry can also be used for opening commands via a magnetic loop sensors.
CLOSING BUTTON
Allows closing with the barrier open.
During opening, when pressed, it stores the command given and at the end of opening, the
barrier closes immediately.
PHOTOCELLS OPERATION
24Vdc power supply to terminals 24 (+) and 25 (-).
The NC contact must be connected to terminals 24 and 27.
If engaged with the bar closed, the opening is still allowed.
If engaged during closing, they make reopen the barrier immediately.
If engaged with the bar open, they do not allow closing.
With the bar open and closing automatically activated, if engaged they renew the automatic
closing waiting time.
AUTOMATIC CLOSING WAITING TIME (TCA)
It can be activated via external switch or wire jumper between terminals 5 and 7.
If the bar is open, the time is renewed whenever it crosses in front of the photocells.
The default programmed time is 10 s.
It is possible to perform the procedure to set a different time (Max 120 s).
CLOSING FROM A TRANSIT (CAT)
By connecting the NC contact of a photocell to terminals 14-15, the transit commands the
immediate closure of the barrier.
During closing, if the photocell contact opens (for the passage of a new vehicle) there will be an
immediate reversal in opening with subsequent closing at the re-closing of the contact (transit
of the completed vehicle).
It is possible to exclude this function by opening the contact of the switch or removing the wire
jumper connected to terminals 5-6 (ECAT).
BOOM UNCOUPLING WITH THE BARRIER CLOSED
This is the automatic reset operation:
HIGHWAY opens at low speeds, reaching full opening.
After 1 second motor M2 is driven to hang the boom.
2 Seconds after happened hook of the boom, HIGHWAY closes with speed standard.
UNCOUPLING WITH THE BOOM OPEN
This is the automatic reset operation: after 2 seconds with the boom uncoupled, the release
is commanded.
The boom then remains open.
M2 MOTOR OPERATING TIME FOR RECOUPLING
Normally, the time taken to recouple the boom is about 3 s, however, if there are impediments,
the time is automatically extended up to a maximum time of 10 s.
If within 10 s the boom has not reached the limit switch that signals the release, the M2 motor
stops and the uncoupling device waits for an open or close command to repeat the release
operation of the boom auction.
The closing of the barrier takes place only if the boom is found in the vertical position and
correctly released (uncoupling sensor engaged).
BARRIER DOOR OPEN SAFETY SWITCH
The opening of the door activates the safety switch that cuts the power to the logic controller,
then all functions are blocked.
To perform functional tests and/or inspections by authorized staff, it is necessary to activate
the switch by pulling out the plastic pin until it clicks.
When reassembling the door, the pin of the switch will reposition itself, reactivating the safety.
