ENGLISH42OBSTACLE SENSORThe PD18 control unit has two independent systems allowingdetection of whether gate movement is impeded by obstacles.The first system is based on measurement of the currentabsorbed by the motor, and is available on all control units: anunexpected increase in current absorption indicates the presenceof an obstacle. The second system is based on measurement ofthe rate of motor rotation and is only available if the encoderoption is present: a decreased rotation rate indicates thepresence of an obstacle.PLEASE NOTE: the amperometric sensor is disabled by defaultand must be enabled by means of the SenS menu option; therate sensor is automatically enabled by enabling the encoderoption, and its sensitivity may be adjusted by means of theS.EnC menu option.The detection of obstacles by means of the amperometric sensoronly occurs if the gate is moving at normal speed. If slowingdown has already started, the obstacle is not detected; thissituation is not hazardous since, during slow motion operation,the motor pushes the obstacle with greatly reduced power.Obstacle detection by means of the rate sensor is also conductedduring slowing down: the alarm threshold is automaticallylowered in order to allow movement at lower speed.When a sensor trips, the gate is stopped and then sent in theopposite direction for 3 seconds, in order to free the obstacle.The subsequent Start command restarts movement in theprevious direction.PLEASE NOTE: if limit switches and slowing are disabled, whenthe amperometric sensor trips, the control unit interrupts thecurrent opening or closing operation, without reversing thedirection of motion.CONTROL UNITCONFIGURATIONThe configuration menu -PrG consists in a list of configurableitems; the display shows the selected item; pushing the wheeldownwards the following item is selected, pushing the wheelupwards the previous item is selected. Pressing the wheel thecurrent value of the selected item is displayed and it ispossible to change it, if necessary.The last item of the menu (FinE) allows to store the changesmade and to revert to the normal working of the control unit.In order not to loose the own configuration it is compulsoryexiting through this menu item.WARNING: If no operations are required for more then aminute, the control unit exits from the programming modewithout saving the given information and changes will belost.Keeping the wheel pushed downwards the configuration menuitems are quickly scrolled down until displayed the item FinE.Likewise, keeping the wheel pushed upwards the items arequickly scrolled down backwards until reached the item t.AP.Like this, the beginning or the end of the list can be reachedquickly.There are the following three kinds of menu items:• Function menu• Time menu• Value menuFunction menu setupFunction menus allow selecting a function from among a groupof available options. When you enter into a function menu, thecurrent active option will be viewed; pushing the programmingwheel upwards or downwards it is possible to scroll down theavailable options. The displayed option is started up pressingthe wheel; after this, back to the configuration menu.Time menu setupTime menus allow setting a function duration. When you enterinto a time menu, the current setup value will be viewed; thedisplay mode depends on the current value:• times being lower than one minute will be viewed as follows:Every time the wheel is pressed upwards (UP) the set timeincreases of half a second; every time it's pressed downwards(DOWN) the time decreases of half a second.• Times between 1 and 10 minutes will be viewed as follows:Every time the wheel is pressed upwards (UP) the set timeincreases of 5 seconds; every time it's pressed downwards(DOWN) the time decreases of 5 seconds.• Times being more than 10 minutes will be viewed as follows:Every time the wheel is pressed upwards (UP) the set timeincreases of half a minute; every time it's pressed downwards(DOWN) the time decreases of half a minute.Keeping the wheel upwards (UP) the time increases quickly,until reached its maximum. Likewise, keeping the wheeldownwards (DOWN) the time decreases quickly, until reached0.0”In some circumstances, setting the value to 0 means that therelevant function is disabled, in this case, ‘no’ will appearinstead of 0.0”.The displayed option is confirmed pressing the wheel (MENU);after this, back to the configuration menu.Value menu setupValue menus are similar to time menus; however, the setupvalue can be any number. Keeping the wheel pressed upwardsor downwards the value increases or decreases slowly.In the following pages the procedure to configure all theparameters of the control unit PD18 is shown step by step
