Fail Safe Alarm System Hanna's exclusive Fail Safe Alarm System protects against problems caused by power supply failure or signal interruption, which are typical risks in industrial environments. An alarm condition is indicated by a red LED, located directly on the front panel of the controller. Overtime Dosage "Overtime dosagein. function with selection knob and jumper for disable on the rear panel. If the dosing relay remains continuously activated for more than selected dosing time the alarm relay is activated, the alarm LED is blinking and the dosing relay is deactivated. ORP Dosing Consent Device When used in conjunction with the HI8720 ORP controller, the ORP Dosing Consent Device function will ensure that the ORP dosage will start only when the pH level is correct. Automatic Temperature Compensation A 2-wire Pt100 can be connected to provide automatic temperature compensation of the pH measurements. Matching Pin Connection Supports potential matching pin connection to avoid typical problems caused by grounding loop current, such as progressive damage of the electrode, fluctuating measurements, and poor process regulation. Robust Design A removable, transparent splash-proof cover protects the front panel.
