Cloud Enabled Swimming Pool Controller with Built-in Dosing Pumps, Analog Outputs and In-line Mounting Kit
Control with Confidence
The BL120 Swimming Pool Controller is a complete system designed for maintaining swimming pool, hot tub, and spa disinfection water quality. The BL120 is available in two configurations. The basic version is the in-line model which allows for direct installation of probe and chemical injection fittings into existing piping. The other version is a panel mounted version with a bypass flow cell. The bypass flow cell allows for calibration and maintenance of the probe without having to shut down the recirculation pump. Additional features of the BL120 include LED indicators for dosing, meter status and service, real-time grapH display, programmable alarms, and password protection.

Controller Overview
Multiple Configurations
The controller is available in one oftwo configurations: an in-line model which allows for directinstallation of the probe and chemical injection fittings into existingpiping (BL120-10) or a panel mounted system with a bypass flow cell (BL120-20). The bypassflow cell allows for calibration and maintenance of the probe withouthaving to stop the recirculation pump.
Digital Combination Probe
The HI1036-1802 is a digital probe thatmeasures pH, ORP, and temperature. This probe also incorporates apotential matching pin. The pin is considered the ?earth ground?connection and is used to prevent ground loop effects from causingerratic readings and damage to the system.
Dosing & Control
Peristaltic Dosing System
The BL120 is equipped with two peristaltic dosing pumps withreplaceable chemical resistant tubing. When using a diapHragm pump,chlorine gas formed from outgassing can collect in the pump headresulting in the pump losing its prime; the buildup of chlorine gas isnot a problem with peristaltic pumps that use rollers and tubing.
Proportional Pump Control
The BL120 features proportionally controlled dosing pumps. Based onthe sensitivity of the process to chemical addition, these controllersallow the user to adjust a proportional band. This setting determinesthe amount of time that the pumps are dosing as a percentage of thedeviation from the set point allowing for very fine control inmaintaining the desired set point.
Adjustable Flow Rate
The flow rate from the dosing pumps is adjustable from 0.5 to3.5L/h. Larger bodies of water require more chemical to be dosed thansmall bodies since it takes more chemical to realize a change in thereading. The adjustable flow rate, like the proportional band, allowsfor better control in maintaining a desired set point.
ORP Dosing Consent
With chlorine disinfection there is an inverse relationship betweenpH and ORP. As the pH level increases, the ORP level decreases. TheBL120 utilizes a dosing consent feature that will not dose chlorineuntil the pH value is first corrected since it is possible to have alow ORP value even though there is sufficient chlorine. The dosingconsent feature prevents wastage of chemicals and avoids a higher thannecessary chlorine concentration.
Connections & Display
Circulation Pump Monitoring
An inline flow switch or amechanical relay connected to the recirculation pump power sourcemay be connected to the hold input of the BL120. With no flow orwhen no power is applied to the recirculation pump, the holdcircuit disables the dosing pumps. This will prevent any dosing ofchemical when there is no movement of water in the system.
Multifaceted Display
The versatile display of the BL121allows for three screen modes. The LCD can display all threeparameters at one time, a 3-second cycle of single parameters, or areal-time plot screen with options for parameter selection,zooming, and log recall.
Programmable Alarm System
Hanna controllers allow users toenable or disable the low and high level of alarms for allparameters. When an alarm is activated, all dosing will stop.The alarm system also offers overdosing protection if the valueis not corrected within a specified time interval then themeter will go into alarm status.
Multicolored LED Indicators
The BL120 offers multiple LEDindicators for status, servicing, and pump operation. TheSTATUS LED changes color based on operational state; green whensetting are in range, yellow when user intervention isrequired, and red for problems. The SERVICE LED indicates anyalarms and process errors experienced by the controller.
Communication & Security
Automatic Logging
The readings for each parameter are automatically logged every10 seconds. A new log is started each time the instrument iscalibrated or at the start of a new day. Logged data include pH,ORP, and temperature values, last calibration data, setupconfiguration, and any event data. Each log is saved as a .csv filefor easy transfer.
USB Connectivity
For review and storage the users can easily transfer data to aPC using a flash drive and the USB port.
Password Protection
Hanna’s BL120 controller features a password protection solutionthat offers restricted access to calibration, setup, and review oflogged data. The password can be set and enabled/disabled duringgeneral setup of the instrument.

COMUNICADO IMPORTANTE:
Al validar su electrodo de ORP, solo debe utilizarse una solución estándar a la vez. Lo ideal es contar con un electrodo exclusivo para cada tipo de solución.
Es importante destacar que el uso conjunto de las soluciones de 240 mV (HI 7021) y 470 mV (HI 7022) puede dañar los electrodos de ORP debido a una reacción química entre sus componentes.
Además, una limpieza inadecuada después de la validación en estas soluciones puede provocar el taponamiento de la unión de referencia, que se manifiesta con un color azul característico.
Si decides, a pesar de la recomendación, utilizar ambas soluciones con un solo electrodo, es fundamental realizar una limpieza profunda del electrodo entre cada validación. Esta limpieza debe hacerse con agua destilada y el electrodo debe secarse completamente con una toalla de papel.
NOTA: En caso de enviar el electrodo para garantía, si se llegara a detectar una contaminación cruzada (color azul en la referencia), la garantía NO se aplica.
HANNA INSTRUMENTS recomienda seguir las indicaciones anteriores para evitar este tipo de situaciones.
