1.2.1 Analog Inputs1.2.1 Analog Inputs
1.2.1 Analog Inputs
The main board of HI 8001 and HI 8002 controllers have on the right side eight inputs dedicated for
the standard analog signals: seven of the 4-20mA type and one of the 0-2V type.
The transmitters have to be connected between the pH, the conductivity sensors and the controller.
They can be supplied from the controller outputs (Vs 12VDC) if the consumption doesn’t exceed 250mA.
These inputs use the transmitters that have source current output type.
The Hanna transmitter code that can be used is HI98143-20 (one EC and one pH channel). When the
user has other Hanna transmitter types it can modify them to the HI98143-20. For modifications
contact the closer Hanna Instruments representative.
1.2.2 Digital Inputs1.2.2 Digital Inputs
1.2.2 Digital Inputs1.2.2 Digital Inputs
1.2.2 Digital Inputs
On the main board, near the analog inputs, the controller has 16 digital inputs with optical separa-
tion. They are available only when the IN24Vac input is supplied with 24Vdc (min. 150mA). The
sensors have to be of switch type and connected to the COM IN pins, near the last digital input.
When between a digital input and the COM IN pin a switch ON is connected , that input is considered
as inactive. Otherwise, when the switch is open or the 24Vac supply is not present that digital input is
active. When the power supply is not present this solution detects and generates the alarm conditions.
The digital inputs assigned to the sensors of the external tank are used to generate a start condition
for the programs (if this setting has been done). In this case the program is started when the switch is
ON (closed).

The RS232 communication is available through the RS232 input placed in the left corner on the
connection panel. This port allows the PC application (Agricare) to transfer the data for the remote
control of HI 8001/2. The serial cable is Hanna serial cable type.
To allow our users access to the latest version of Hanna Instruments PC compatible software, we
made the products available for download at http://software.hannainst.com. Select the product code

1.2.4 Accumulator input
This input is not accessible outside the controller. In case of power failure the controller uses a backup
source (9V and 100mAh Nickel Cadmium accumulator) that can supply the controller for about 2h (at
40mA consumption, in Power Safe Mode). The controller consumption in the power safe mode
depends on the digital input number connected to the COM IN pin.

The controller works when the 220V(110V)-dc power supply is connected to the 220Vac input and an
auxiliary 24Vdc(min.150mA) voltage is connected to the IN24Vac input. This source doesn’t supply
internally the digital outputs and should be separated from the external 24Vac power supply used for
the valves. The PE pin from the power supply input must be connected to the ground protection line
(see in the appendix).

This output has 12Vdc and is dedicated to supply the transmitters. Two HI98143-20 transmitters can
be supplied from this output (2-pH channels and 2-EC channels). If another source is used to supply
the transmitters, than a short circuit has to be between the –Vs (12V) pin and the ground of the
external source. When the user connects the EC-in sensor, the third transmitter should be supplied
from this output.

The other digital outputs are of relay type and also support 10A. For this output type only the NO and
COMMON terminals are accessible on the connector . Twenty-four of these outputs are on the
extension board and can be optional. The remaining outputs are on the main board. For the
extension board, all the COM relay terminals are placed together (inside the controller) at the COM
OUT3 output.
An active output means a short-circuit between that output pin and the COM OUT 1(3) pin from the
same group.

TION TYPES
The hardware architecture can be simplified (pH and EC sensor number, external tank number, and
fertilizer tank number). The controller is produced in four versions (8,16,24 and 32 sectors). The
architecture should be clarified before starting the installation. It depends on:
- pH sensor number
- EC sensor number
- fertilizer tank number
- filter number
- external tank number
- differential presostate number
- sectors number
- agitator number
-other problems that can be generated by external devices (power supply voltage, valve features,
irrigation counter features, pump features, alarm device features, transmitter’s features and
level sensor’s features).
When these external device parameters are not identical with those in the Inputs Outputs Description,
the installation could require modifications on the external devices (transmitters, level sensors etc.)
and/or supplementary components (relays, auxiliary supplies).
The most important things that have to be checked are:
· The main power supply voltage should be the same with the controller voltage.
· The external transformer parameters should be as in chapter 1.2
· The transmitters should be as in chapter 1.2 .
· The devices connected to the digital inputs should be as in chapter 1.2

A separate 24Vdc (150mA) source should be used for this supply. It supplies the digital inputs. The
transformer that is used for the valves could provide the voltage for these inputs, but it needs a
separate winding. The IN 24Vac input can be connected to the same transformer but in this case, here
connections with COM IN pins have to be avoided.

The digital inputs have to be connected as in the next figure. All these inputs are mechanical contacts
form switches or relay contacts. When one of the digital inputs is not used (fert. level, acid level, dif.
pres., irrig. counter) it should be connected to the COM IN pin. The unused external tank’s level inputs
have to remain unconnected.

2.2.4 Analog input connections
The pH, EC and solar radiation sensors have be connected to the analog inputs through the transmit-
ters, that have 4-20mA (source current type) outputs and 0-2V (solar radiation). The Hanna
transmitters that can be used are HI98143-22 (1 pH, 1 EC). The user can or can not use the second pH,
EC sensors or the pH input sensor. The number os EC, pH sensors is configured within panel S55 -
SENSOR CONFIG.
The EC-in sensor can be replaced from installation without modifications. Thus, the “EC-in “ input will
stay unconnected.
The transmitters will be supplied from the +/-Vs outputs. The maximum consumption supported by
the controller is around 250mA (12V). This means that two Hanna transmitters can be supplied from
the same output (2 pH channels and 2 EC channels) and one transmitter for the EC-in sensor.
The following type of sensors can be connected to the transmitters:

The valves have to be connected as in the following figure. Each group of 8 valves has a common pin
placed near the valve’s output called COM OUT 1, 2, 3. The valves are not supplied from the controller.

In this case the external transformer should support the consumption for all loads connected to 24Vdc.
The sector outputs from the main board, together with the agitators and the main pump output have
a common fuse, F3. The valves numbered from 9 to 32 have the F1 common fuse on the extension
board.
Filter schematic
The HI 8001 (2) controller has the programs to clean the filters. This operation is done by the four
valves that are commanded alternatively two by two like in the schematic. The controller provides a
mechanical contact that is switched ON/OFF periodically and it can be used in the installation to
control the external relay (see in the appendix).

The controller cannot command the pump directly. Thus, the digital output generates the command
for the external pump relay.

After all the connections have been made according to the controller type and specifications, you
should follow the next steps:
- Disconnect the main supply from the controller (J1 connector)
- Close the K1 switch; verify if there are short-circuits (the fuse F1 blow up)
- verify the analog inputs (sensors, connections, transmitters)
- Turns OFF the Stop switch and supply the controller (connect J1)
- After initialization the Controller State should be in the STOP state
- Go in the S50 (OUTLETS MANUAL CTRL) panel
- For each output device connected to the controller you can verify the correct functioning step by
step. Set and clear the desired output according to the table from APPENDIX 2 (InstructionInstruction
