8. SAFETIES OPERATING LOGIC
•Photocell (PHO input)
When triggered photocell causes:
- movement reversal when closing, either immediately or upon release as programmed;
- no effect when opening;
- no effect when opening a closed gate if set for immediate reversal, otherwise a delay until it is reset;
- closing inhibition in case of open gate.
Note:The control unit is endowed with a quick closing function so that when automatic closing is
enabled the resetting of a photocell that has triggered during opening or pause immediately causes the
gate to close without the unit waiting any further for pause time to expire.
•Opening Safety (EDG input)
Safeties, such as flush or pneumatic hips, etc., and regardless of whether testable or not, may be connected to
input “EDG”.
Safety activation causes:
- no effect during closing;
- movement reversal during opening for two seconds;
- opening inhibition when access is closed;
- closing inhibition when access is open.
•Logic STOP (STP input)
Logic STOP activation causes the stop of all the functions.
To reactivate the manoeuvre it is necessary to disengage the stop and give another command.
9. CONTROL UNIT OPERATIONS
9.1 TURNING ON
Upon turning on, the unit’s yellow SET LED starts blinking for five seconds indicating LEARNING mode
accessibility for reprogramming. Commence operations once the yellow LED has gone off. Persistent red LED
indicates failure of the EEPROM memory that contains necessary radio codes and unit's operating parameters.
Under such conditions, no operation may be performed until the unit is programmed all over again or the
EEPROM card replaced.
9.2 AUTOMATIC OPERATION
Set the “PAU”trimmer cursor to an intermediate position between 0 and the second-last notch according to
desired pause time to program automatic mode.
A radio command or one given via the “STR”input causes the control unit to:
- pre-blink for one second;
- actuate the motor;
- ceasing the opening upon limit switch triggering, or upon expiry of pre-set operation time.
pre-blink for two seconds after expiry of pause time before starting to close again by:
- actuating the motor
- ceasing the closing upon limit switch triggering, or upon expiry of pre-set operation time.
Note: With manual opening contact (terminal STR) closed, the control unit doesn't perform automatic
closing, for which, the contact must be reopened.
9.3 STEP-BY-STEP OPERATION
Turn the “PAU”trimmer cursor all the way down to cut out automatic closing and program step-by-step mode.
The step-by-step sequence is OPEN-STOP-CLOSE-STOP.
Opening and closing operations are performed as described in the foregoing sub-section.
9.4 PEDESTRIAN OPENING
A command given via the PEDESTRIAN OPENING input ("EDG" terminal) or radio (if enabled) causes the
control unit to open for 5 seconds or for the time set during the LEARNING routine (if performed).
Closing may take place either automatically (in case of the automatic closing function being enabled) or upon
giving a further manual command.
The full opening command always has priority over pedestrian opening so that a full opening command given
during pedestrian opening will cause to fully open.
