BL983314-1: 300 g (10.6 oz.) Ordering Information BL983314-0 (12 VDC) and BL983314-1 ( 115/230V) are supplied with mounting brackets, transparent cover and instruction manual. Recommended Probe HI3314 resistivity probe with 2 m (6.6’) cable (included) BL983314 Resistivity Mini Controllers • Large Clear LCD • Fire Retardant Casing • Splash-Resistant Cover The BL983314 is a simple to operate resistivity controller designed for ultra pure water, reverse osmosis, and water conditioning applications. The BL983314 resistivity controller is also ideal for continuous monitoring of process solutions. Setpoint and calibration are manually adjusted with a trimmer and the alarm relay allows for simple control. Adjustable Dry Contact Dosing Relay The BL983314 features a dosing relay that is activated when the reading is below 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 the set point. Orange/Yellow = Reading is below the set point and the relay is activated. 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. 15 Process Instrumentation 15.95 www.hannainst.com | controllers
