Page 45: Connections Definition
As explained above at paragraph 5.1 the local I/O DC/AC interfaces can drive 1 or 2 I/O boards, a single I/O board contains 16 outputs and 8 inputs (16/8) and 2 I/O boards will contain 32 outputs and 16 inputs (32/16). Therefore when defining local I/O interface DC or AC we need to specify whether it is for 16/8 or 32/16 outputs and inputs. - Page 46 Onboard location number Interface address Valve 1 of line 8 by radio interface 4 RTU 1 output 1 Filter 4 by interface 1 output 8 Valve 6 of line 6 by interface 3 (2 wired), RTU 16, output 2. Valve 1 of line 7 by interface 2 (REMOTE I/O), output 1, without RTU.

Page 48: Testing Operation Of Inputs And Outputs
7.3 Testing operation of inputs and outputs Let us assume that all the outputs and inputs were properly connected according to the connections table described above. However before all the outputs and all the inputs were tested one by one we cannot be sure that they are all functioning as expected. In this document we explain how to carry out the testing through the local MMI of the controller. -
Page 49: What Comes Next
For example, water meters and fertilizer meters need to have their ratio defined; irrigation valves need to have their nominal flow and filling time defined. Both of the two subjects are covered in details in the “DREAM 2 USER GUIDE 2016”. -
Page 50: The Dream Simulation Software
THE DREAM SIMULATION SOFTWARE The DREAM SIMULATION SOFTWARE is a program that enables simulating the DREAM on the PC. The simulation software is a very useful tool for demonstrating, training, experimenting and checking problems. The simulation software will login into the SERVER and then it becomes accessible through the CONSOLE or the SPOT. -
Page 51: Supplementary Devices
The DREAM simulation may also be used for defining a new configuration that can be saved in a configuration file that can later be loaded into the DREAM controller. SUPPLEMENTARY DEVICES In this chapter we shall describe some devices that are used in the DREAM 2 system in special cases. 9.1 Switching electric pumps... - Page 52 The switching units with command of 12v DC latching can be commanded either by three wired command or two wired command. All types of switching units act like a relay that when activated they let the power through and when deactivated they cut off the power from the load. In any case, the power to be switched comes from external source and not generated internally by the unit.
-
Page 55: The Three Functions Of The Rebran Board
IMPORTANT: It is important to point out that unlike the AC type pump-switching units, the DC type units require a power supply of 12v DC without which they would not function. When the pump-switching unit is commanded by the local I/O of the DREAM or the remote I/O expansion unit, the 12v can be taken from the power supply of the DREAM or of the expansion unit. -

galvanically disconnected. This feature helps to solve problems created by leaking communication lines. Repeaters may be needed in two cases: 1. When the RS485 line gives poor results and the signal needs strengthening. 2. When the system contains several 2 wired channels and we want to isolate each channel from the others. -
Page 57: Rs485 Bridge
The board can be plugged into the motherboard directly or connected remotely through the remote I/O RS485 channel. When installed remotely the board requires 12v DC for energizing and 2 wires for the RS485 communication. The board enables reading up to 4 analog inputs of 4-20 mA or 0-5v. Each DIP switch of S2 when set in upper position indicates 4-20 mA input. - Page 58 "x" input pulses counted. The number “x” is based on the selected setting. A special case is when “x” equals 1, then for each pulse received at the input there will be one pulse generated as output. The width of the positive and negative parts of the pulse will be no less than 1 second.
