DESCRIPTION:
• This unit is used to activate solenoids and read meters and sensors from a distance using a 2-wire ca-
ble. According to the model, the Agrónic Monocable module (MAM) can connect up to:
MAM2-41:
o
2 latch solenoids of 2 wires (or 1 of 3 wires)
4 digital inputs (2 can be meters)
1 sensor
MAM5-71:
o
5 latch solenoids of 2 wires (or 2 of 3 wires)
7 digital inputs (5 can be meters)
1 sensor
MAM8-101:
o
8 latch solenoids of 2 wires (or 4 of 3 wires)
10 digital inputs (8 can be meters)
1 sensor
• The connection between the MAM and the Agrónic is done through a linking unit, the Agrónic Mono-
cable Link (EAM). A 2-wire cable from the EAM connects all the MAMs. This cable not only communi-
cates the MAM but it also provides them with electrical power.
• Up to 120 MAM modules can be connected to a single EAM.
• The distance between the EAM and the last MAM on the line can surpass 10 km. (under certain condi-
tions).
• The built-in light indicates when the unit is communicating.
• Configuration and consultation using a Modules Reader (or through another reader, the Agrónic Mo-
nocable Reader, LAM) with screen and keyboard.
• Two-fold security:
The battery in each MAM lasts over 30 hours in the event of a power failure or a power cut in the
o
Monocable.
The batteries in the EAM last several hours in the even of a general power failure. With larger ca-
o
pacity batteries, it can keep operating for several days.
• Protection against overloads.

    TECHNICAL CHARACTERISTICS: Power supply Power source 24Vdc through the Monocable bus, -20% +25% Energy consumption: At rest: 2 mW While communicating: Outputs Inputs Number 2 / 5 / 8 Digital Number 4 / 7 / 10 Type 12 Vdc or 16 Vdc Type free power contact Trigger time: 80 ms...
  • Page 3: Operation

    OPERATION: The Agrónic Monocable system operates with a linking unit, the Agrónic Monocable Link (EAM), which con- nects to the Agrónic using a RS485 bus or RS232 serial port and the ModBus communication protocol. The EAM supplies the 24 Vdc which powers the entire Monocable system and distributes it through a 2-wire cable which in turn connects all the Agrónic Monocable Modules (MAM).
  • Page 4 AGRÓNIC MONOCABLE MODULE CONNECTIONS: AGRÓNIC MONOCABLE MODULE EXTENSION (AMAM): When an MAM has more than two outputs, it has an extension module (AMAM) to connect up the inputs and outputs after the second one. According to the MAM model, this is formed by: •...
  • Page 5 CONFIGURATION: The configuration on the MAM is made using the Modules Reader (or the LAM reader model, Lector Agrónic Monocable,) consisting of a screen and four keys, which is connected to the MAM through the extension con- nector. It is not necessary to disconnect the MAM in order to connect it. After connection the Modules Reader, press a key for the screen to display the consultation.
  • Page 6: Practical Tips

    Configuration: MAM number: a value from 1 to 120 is used to distinguish the 120 possible modules which can be con- nected to an EAM. 3W Valve: a “no” response indicates that 2-wire latch solenoid will be used; with “yes”, 3-wire latch sole- noid is used.
  • Page 7 RECOMMENDATIONS FOR INSTALLING THE MONOCABLE BUS: • Unit distribution: Have a map or sketch with the location of the modules to make them easier to install and start up, taking into consideration the configuration Sistemes Electrònics Progrés S.A. has provided regarding the distance between the Agrónic and the modules.
  • Page 8 Avoid scrapes or slight cuts in the cable as it can cause variations in the cable magnitude (capacities, inductances, resistances, etc.) which directly affect communication signals. As a cable covering ma- terial, use the same soil bed where the pipelines have been laid. Respect the safety distances in the cable when connecting the modules to prevent machinery from breaking it.
  • Page 12 ATTENTION: It is extremely important to keep the box watertight Close the lid properly Insert the cable hose through the compression gland and tighten it as much as possible If several cables are inserted through one compression gland, seal the gland to keep it watertight Cover the glands that have no cables Protect the case against sunlight and water (rainfall or irrigation)
