Environmental controller for enclosed spaces
such as greenhouses, farms, dryers, cold rooms, etc.
The Ambitrol 100 is an electronic system for the automatic control of the existing environmental parameters in closed areas such as greenhouses, farms, dryers, cold rooms, etc. with 8 analogue inputs (for sensors) and 1 or 2 digital inputs (to condition operations), plus 3 or 8 analogue outputs (from 0 to 10 V) and 8 or 16 relay outputs (all/nothing), with 10 control programmes.
Due to its configurable condition (the assembler can adapt it to the particular needs of each installation) with the same controller and through these 10 programs, temperature sensors such as relative humidity, luminosity, etc. can also be controlled; as well as acting on multiple windows, fans, heaters, refrigerators, humidifiers, irrigation, alarms, illuminations, engines, etc.
For example: the same controller is also used to control the fans of 7 warehouses, with their respective maximum and minimum alarms, as well as to control the heating, ventilation (fans + windows) and lighting of 3 warehouses, also with their respective alarms.
Choose between the box format, for installation anywhere, or the build-in format for placement in cabinets.
FeaturesThese are the available features of the controller
The controller has capacity for 10 very complete programs.
We call program to an operation order that is prefixed in the controller for its automatic execution.
The programs are identified with an order number and with a descriptive text of the control they carry out, to be chosen by the user himself, such as, for example, Cale-1 (heating nº 1).
Each program is configurable in their inputs, outputs, conditioning factors, reference and differential values, curves, maximum and minimum alarms, types of operation, and so on.
Each program can read one or two sensors (if there are two, it applies the average).
A program normally needs to read from a sensor located in the installation in order to compare this value with the preset and thus act on the corresponding output.
The same sensor can also be read by several programs.
The units of measurement that can be controlled by the controller, using the corresponding sensors or counters, and whose abbreviation appears on the screen, are:
Temperature ºC, humidity relat. %RH, lighting Klx, ratio %, speed Km/h, direction °, acidity pH, radiation W/m2, units Uds, pressure Psi, flow m3/h, flow l/h, anhi. Carb. CO2, NH3 ammonia.
All programs have an output
A relay output (which it only activates or deactivates) or analogue output (which, when it activates it, it does with a lower or higher voltage depending on the difference between the value read by the probe and the one preset in the program).
The relay outputs can also act with modulation of the activation time, proportional to the changes of the sensors.
The analog value of the outputs is from 0 to 10 V and corresponds to 0 to 100 % of the output value that will be indicated on the display. (It is also possible to work with inverted signal from 10 to 0 V).
Minimum and maximum output voltage limits can be provided for, for example, speed controllers that need to work from 2 to 8 volts, etc.
However, a program may not have an actuation output assigned to it, but can be used to condition other programs when certain circumstances occur; for example, when an excess of wind must modify the actuation of one or more programs that control windows, or when it is necessary to condition the reading of a sensor to a certain time.
Any program can be "conditioned" by another and, at the same time, be a "conditioner" of the others.
It can also be conditioned by one of the two existing digital inputs (to connect external security elements to the controller).
REFERENCES AND CURVES
The references, in general, are those reading values from which we want to activate or deactivate an output.
We call differential the difference in value desired between opening and closing an output, or vice versa.
The references can be programmed manually (modifying them personally each time it is necessary) or following curves pre-set by the user himself once and which are automatically modified with the passage of time, as planned. There are 1 or 2 curves per program, depending on the type.
The incorporation of pre-set performance curves gives great agility to those controls in which references must be changed periodically, such as, for example, the temperature in the fattening of chickens, the lighting schedule in laying-hens, etc.
Each program, except for 2 types, can also be preset with maximum and minimum alarm values that are used to detect faults or other problems in the facilities and auxiliary elements they control.
These values are constantly added (maximum) and subtracted (minimum) from the program reference and, if the controlled value exceeds the maximum or minimum for a period of more than 30 seconds, an output is activated to which an acoustic, luminous, telephone or radio warning device can be connected.
ANOMALIES AND HISTORY
The controller has a record of the last 15 incidents occurred in the installation, which we call anomalies, which memorizes the alarms produced, power cuts, etc..
The history is a statistical record of the last seven days for each of the programs.
Among other data, it indicates day by day the hours that the output has been activated (if it is by relay) or the average of the percentage of the value of the output (if it is analogical), as well as the average reading of the sensor, the highest and the lowest. You can also record the daily consumption of water and feed, or other products.
Through a simple key, called consult, it is possible to examine program by program:
The current day and time, the anomalies registered, the value of the parameters controlled by the probes, the status of the outputs with all their details, the time remaining to conclude an action in the hourly programs, etc.
Model Ambitrol 101 - without analog outputs.
Model Ambitrol 102 - with 3 analog outputs expandable to 4.
Model Ambitrol 103 - with 8 analog outputs.
220 Vac and 12 Vdc versions (battery).
Version "100H" to humidify different warehouses or greenhouses, activating the solenoid valves sequentially one after the other with a single pump. The time that each solenoid valve will actuate will be regulated according to the temperature or relative humidity difference.
Version "100HFA" which, in addition to incorporating the function of version "100H", in actuation type nº 9 changes its way of acting.
