BL983317 • BL983327 EC Mini Controllers Measuring in mS/cm • Models available with 4-20 mA galvanic isolated output with external dosing disable contact • Large Clear LCD • Fire Retardant Casing • Splash-Resistant Cover The BL983317 and BL983327 are compact, panel mounted, process controllers for measuring conductivity of a process stream. The device features a large LCD with protective cover. Users may choose from automatic or manual dosing modes. BL983317: When in automatic mode, the dry contact relay is activated when a reading is below the set point. The relay can be used to activate a dosing pump to add chemical until the desired set point is reached. Chemicals that can be dosed include nutrient solutions. BL983327: When in automatic mode, the dry contact relay is activated when a reading is above the set point. The relay can be used to activate a solenoid valve to open and drain a tank (i.e. boiler bleed and feed) or add freshwater until the desired set point is reached. Adjustable Dry Contact Dosing Relay The BL983317 features a dosing relay that is activated when the reading is below a user programmable set point. The BL983327 features a dosing relay that is activated when the reading is above a user programmable set point. Programmable Overdose Protection For enhanced safety the mini controller can be programmed to deactivate the dosing relay if the set point is not reached within a specified time interval. The overdosing timer is programmable from 5 to 30 minutes or disabled. Relay Control Override With the flick of a switch the mini controller's relay can be disabled (Off), placed in control (Auto), or be activated for manual operation (On) which is useful for priming a dosing pump. Multicolor LED Indicator Multicolor LED indicator allows an operator to quickly check the status of the controller. Green = Meter in measurement mode and reading is above (BL983317) or below (BL983327) the set point. Orange/Yellow = Reading is below (BL983317) or above (BL983327) the set point and the relay is active. Blinking Red = Indicates an alarm condition such as when the maximum dosing time has been exceeded. Fuse Protected Dosing Contacts The relay dosing contact is rated for up to a 2A load and is fuse protected. Labeled Termination Connections Quick-connect terminal blocks are clearly labeled for easy connection to power, conductivity probe and relay that can be used to operate a dosing pump, valve, audible alarm, or light.
