CTR320 - INSTRUCTIONS
Electronic board controlling 1 or 2 230 Vac single-phase asynchronous motors destined to swing gate automation.
Definitions
Start (ST) - Contact N.O.
Input to be used to require the opening or closing of the gate (both leaves).
Pedestrian start (PD) - Contact N.O.
Input to be used to require the opening or closing of one leaf only (M2 - pedestrian leaf). Pedestrian start control is irrelevant during a Start
cycle until the closing step end (closed gate). During a Pedestrian start cycle, Start control is always working and causes the start of an
opening cycle of both leaves.
Stop (STOP) - Contact N.C.
It prevents the start of working cycle. If the Stop command is supplied during the motion, it provokes the immediate stop of the gate. The gate
remain in stop as long as the contact is opened. After a Stop command the following Start command always starts an opening cycle. A Stop
command supplied during the pause time interrupts the work cycle.
Photocell (FC) - Contact N.C.
It is an optical barrier intended to intercept and signal the passage of people or vehicles along the path crossing the gate or in the area nearby it.
The photocell is affecting but during closing step and in the pause time. If an obstacle darkens the photocell while closing it provokes the stop and
motion reverse after 1,5 sec.. The intervention of the photocell during the pause time reloads it extending the period before automatic closing.
Photostop (FS) - Contact N.C.
It is an optical barrier intended to intercept and signal the passage of people or vehicles along the path crossing the gate or in the area nearby it.
If an obstacle darkens the Photostop during the motion or in the step previous to the work cycle start, it determines a temporary stop of the gate.
The blinker signals by a fixed light the anomalous condition. As soon as the obstacle is removed an opening cycle starts, except when the gate is
fully opened. In that case a closing cycle will start. The intervention of the Photostop during the pause time reloads it extending the period before
automatic closing.
Blinker (LAMP)
It is lamp intended to signal the danger condition due to moving gate. Blinking logics are the following ones:

Fast (2 blinking/sec.): signals the opening phase

Slow (1 blinking/sec.): signals the closing phase

Fixed light: signals that the gate is stopped, waiting for the removal of the obstacle that darken the Photocell or the Photostop.
Motor 1 (MOT1)
Outputs for the control open / close of the motor connected to the first gate leaf in closing phase.
Motor 2 (MOT2)
Outputs for the control open / close of the motor connected to the gate leaf delayed in closing phase.
Electric lock (SERR)
Impulse control for the release of electric lock. The electric lock must be connected to the leaf operated by the motor M2.
Open gate lamp (CANC.AP)
The lamp is switched off only when the gate is fully closed.
Courtesy light (CORT)
Control of a lamp lighting up the area around the gate. The lamp keeps switched on for 2 minutes after cycle end.
Signalling Leds
DL1 - Programming Led (red): It switches on in programming phase and during gate motion.
DL2 - Start Led (green): It switches on at a start control in terminal board.
DL3 - Pedestrian start Led (green): It switches on at a pedestrian start control in terminal board.
DL4 - Stop Led (red): It switches off at a stop control in terminal board.
DL5 - Photocell Led (yellow): It switches off when the photocell is darkened.
DL6 - Photostop Led (yellow): It switches off when the photoelectric cell is darkened.
Trimmer
RV1 - It regulates torque of the motor during the normal speed phase. Clockwise rotation increases the thrust of the gate.
Programming keys
P1 - Allows to insert/cancel the remote control codes in the memory
P2 - Allows to set the pause time and the M2 motor's closing delay
P3 - Allows to set the working time of the leaves.
Dip-switches
DP1 - Automatic closing (ON = Step-by-step with automatic closing OFF = Step-by-step without automatic closing). DP2 must be ON.
DP2 - Condominium logic (ON = Step-by-step
DP3 - Immediate closing (ON = Step-by-step with immediate closing
DP4 - Extra-push (ON = Extra-push enabled
DP5 - Erasing of all delays between leaves (ON = Delays erased OFF = Delays enabled)
Technical features
Slow-down (soft stop)
At stroke end the unit reduces the speed of leaves (Soft stop function) so to avoid strong impacts.
Radio receiver
The electronic card CTR320 contains a 3 channels radio receiver. The receiver can memorize up to 100 codes. The channel 1 of receiver acts as
Start, while the channel 2 acts as Pedestrian Start. The channel 3 switches on the Courtesy light for approx. 2 minutes.
Extra-push (DP4=ON)
It is possible to enable the "extra-push" function, used to make easy the release of electric lock in bad weather conditions. The "extra-push"
function operates only with closed gate and is a logical sequence starting the electric lock during a short closing step (1 sec. approx.) and disables it
only after the leaf's start in opening. At closing end the electronic card supplies a short acceleration on both leaves (1,5 sec) at the maximum speed
so to make easy the electric lock's insertion.
Erasing of all delays (DP5=ON)
This function allows you to cancel all the delays between the leaves. The two leaves open and close simultaneously.
Torque regulation
The torque of the electric motors can be adjusted using the RV1 trimmer. Turning clockwise, the thrust of the leaves increases.
OFF = Condominium mode)
OFF = Step-by-step without immediate closing). DP2 must be ON.
OFF = Extra-push disabled)
