= '''<big>Operating principle and mode settings</big>''' = | |||
DU-180 transmits the current angle via the '''RS-485''' interface ('''LLS''' protocol), or via the '''frequency interface''' ('''in Hz'''). The tilt angle value is within '''0–180 degrees''' ('''300–480 Hz'''). If the tilt angle '''exceeds''' 180 degrees, the countdown starts from '''0'''. Additionally, information about the '''operation''' is transmitted via '''discrete''' outputs. In this case, voltage appears or disappears on them. Discrete outputs '''(green and purple)''' should be connected to the '''contact registration''' device (for example, the analog terminal input) as Normally Open (or Normally Closed - depends on the mode) plus - the voltage at the terminals can be from '''4V to the power source '''voltage. '''It is prohibited to connect a load to discrete outputs'''. In addition, the DU-180 sensor can transmit the tilt angle relative to another DU-180 sensor, the so-called '''differential mode'''. In this case, the angle of one sensor relative to the other in '''Hz''' will be used. | |||
== '''<big>Garbage truck mode</big>''' == | |||
This mode is used to control the tilt angle of the garbage truck lifting frame. The current tilt angle will be transmitted via the '''RS-485''' interface, and the '''discrete''' outputs '''will transmit the triggering events (crossing the control angles)''' | |||
[[File:ImageWQEQWE12E1.png|center|frameless|713x713px]] | |||
[[File:Image312.png|center|frameless|772x772px]] | |||
This mode sets two angles Top and Down. To set the sensor angles in the Garbage Truck mode: | |||
*Place the sensor in the operating position and press '''Set Zero''' | |||
*Select '''Garbage Truck''' mode | |||
*Enter the value for '''Top''' and click '''Save the parameters to device'''. | |||
*Enter the value '''Down''' and click '''Save the parameters to device'''. The Down must be less than the Top | |||
*If necessary, set the '''network address''' and click '''Save the parameters to device''' again. | |||
After crossing the triggering angles, the state of the discrete outputs will change according to the table. It is possible to record the fact of a complete cycle of lifting and lowering of the waste container | |||

== '''<big>Dump truck mode</big>''' == | |||
This mode is designed to control the angle of inclination of various elements of vehicles: dump truck body, crane boom, tanker hatch, etc. The sensor will transmit the angle value via '''RS-485''' interface, and '''discrete outputs''' will trigger the crossing of control angles. | |||
[[File:Imagee12 d1c 1.png|center|frameless|832x832px]] | |||
[[File:Imagecc32d1.png|center|frameless|766x766px]] | |||
In this mode, two angles '''Top and Down''' are set. To set the sensor in '''Dump truck''' mode: | |||
*Place the sensor in the operating position and press '''Set zero''' | |||
*Select '''Dump Truck''' mode | |||
*Enter the value for '''Top''' and click '''Save the parameters to device''' - Top control angle. | |||
*Enter the value for '''Down''' and click '''Save the parameters to device'''. The '''Down''' must be less than the Top - Down control angle | |||
*If necessary, set the '''network address''' and click '''Save the parameters to device''' again. | |||
When the triggering angles are crossed, the state of the discrete outputs will change according to the table. You can use both discrete outputs or one of them for triggering. | |||

== '''<big>Frequency mode</big>''' == | |||
This mode is used to control the tilt angle of a vehicle component when the head unit (terminal) '''does not have digital inputs'''. The angle is transmitted through the '''frequency channel''' (green wire) in the range of 300Hz (0) - 480Hz (180). | |||
The crossing of the control angle (parameter Down) is signaled by the disappearance of voltage on the purple output of the sensor. | |||
[[File:Imageqd21v1.png|center|frameless|789x789px]] | |||
To set the sensor in '''Frequency''' mode: | |||
*Place the sensor in the operating position and press '''Set zero''' | |||
*Select '''Frequency''' mode | |||
*Enter the value for '''Down''' and click '''Save the parameters to device'''. | |||
*If necessary, set the '''network address''' and click '''Save the parameters to device''' again. | |||
The operation of the purple output is described in the table: | |||
[[File:Imagecerb3b33 35t.png|center|frameless|520x520px]] | |||
== '''<big>Bucket mode</big>''' == | |||
This mode is designed for use on excavators to control the bucket operating time. The angle is '''periodically''' measured and '''compared with''' the previous one, if the angle changes and the difference between the current angle and the previous angle is '''greater than the set delta''', the green output will show a voltage signaling '''a trigger'''. If the angle stops changing or the difference between the two angles is less than the set delta, then after expiration of '''digital output turn off''' the voltage on the green output will disappear. | |||
In this mode the angle is transmitted via '''RS-48'''5 interface. | |||
[[File:Imagef13r 23r23.png|center|frameless|812x812px]] | |||
[[File:Imageвы 1 12у 1.png|center|frameless|768x768px]] | |||
The parameter '''Digital output turn on''' sets the angle measurement interval, at the beginning of which the current angle value is '''memorized'''. After expiration of this delay, the new current value is read, compared with the previous value, if the difference is a certain angle, which is greater than or equal to the '''“Delta”''' value, then the green discrete output will show a positive voltage (triggering, '''“sensor in operation”'''). If the '''“sensor in operation”''' and the difference value has not exceeded the set angle, the delay for '''switching off''' is started (parameter '''Digital output turn off''') and if during this time the difference of angles does not exceed the set '''Delta''' value - the voltage on the green output disappears. This separates the working and idle time of the implement. | |||
To set the sensor in '''Bucket''' mode: | |||
*Place the sensor in the operating position and press '''Set zero''' | |||
*Select '''Bucket''' mode | |||
*Enter the value for '''Delta''', '''Digital output turn of''', '''Digital output turn off''' and click '''Save the parameters to device'''. | |||
*If necessary, set the '''network address''' and click '''Save the parameters to device''' again. | |||

== '''<big>Plow mode</big>''' == | |||
The mode is designed for installation on the '''“plow”''' type devices of snowplows used for road clearing. In this mode the sensor will transmit information that the plow is lowered and is in working position, the algorithm of operation allows to avoid false messages about the end of work when the plow is raised when passing obstacles. | |||
'''The plow must have a significant stroke to avoid false alarms caused by road irregularities (the difference between the raised and lowered angles must be greater than the vehicle inclination on irregularities).''' | |||

[[File:Imaged 1d 12 d1c1 .png|center|frameless|759x759px]] | |||
'''Zero''' is set in '''working position''' when the plow is lowered. The sensor crosses the '''“TOP”''' and '''“DOWN”''' boundaries as the machine moves from the travel position to the working position. When the '''“DOWN”''' angle is crossed to a lower angle, the '''“Digital output turn on”''' delay timer is started. If at the end of the '''“Digital output turn on”''' timer the current angle does not exceed the '''“DOWN”''' angle, the discrete output ('''green''') will trigger and a positive voltage will appear on it. | |||
When the '''"DOWN"''' limit is crossed in the direction of a larger angle (when the moldboard is raised), the '''"Digital output turn off"''' timer is started. If the current angle remains greater than the '''"DOWN"''' limit when the '''"Digital output turn off"''' timer expires, the discrete output will open. If the sensor crosses back the “DOWN” boundary towards a smaller angle, the running '''"Digital output turn off"''' timer is reset. | |||
If it crosses “TOP” towards a higher angle, the discrete output will open '''momentarily'''. This is done in order to get a clearer readout of the discrete outputs switching (short-term raising and lowering of the gun during obstacle avoidance and turns is avoided). | |||
To set the sensor in '''Frequency''' mode: | |||
*Place the sensor in the operating position and press '''Set zero''' | |||
*Select '''Plow''' mode | |||
*Enter the value for '''Down''', '''Top''', '''Digital output turn on''', '''Digital output turn off''' and click '''Save the parameters to device'''. | |||
*If necessary, set the '''network address''' and click '''Save the parameters to device''' again. | |||

== '''<big>Difference mode</big>''' == | |||
'''Difference tilt sensor''' is a conventional angle sensor DU-180 with the ability to independently send requests via '''RS-485''' interface and, based on the data received from the '''second sensor''' connected to it, produce a differential angle difference between the '''two devices'''. '''This mode is used to reduce false alarms due to the tilt of the entire vehicle'''. | |||
The '''RS-485''' outputs of both sensors should be connected to each other to exchange data between them ('''Line A''' of one sensor should be connected to '''line A''' of the second sensor, similarly for '''line B''') The sensor sending the requests is the '''“master”''', the second sensor is the '''“slave”'''. In this mode, the '''master''' will transmit the '''differential angle''' (angle between the two sensors + base frequency 300Hz) as a frequency signal via the '''green wire'''. The frequency will vary in the range from 300 to 480 Hz, which corresponds to the angle value in the range from '''0 to 180 degrees'''. | |||

[[File:Imagehh6 jk6.png|center|frameless|766x766px]] | |||
To configure the '''Slave''' sensor for '''difference mode''': | |||
*Place the sensor on the '''moving element''' of the vehicle in the operating position and press the | |||
'''Set zero''' | |||
*Select one of the modes ('''any''' mode except '''Master''') | |||
*Set '''network address 1''' and click '''Save the parameters to device''' | |||
