General overview of the HI-510 series

The controller features a digital probe input(s) that automatically detects and updates the controller with the parameter that it is measuring.

Need a dual-input process controller? Then look at the HI-520. It is Hanna's first dual-input process controller that accepts virtually any combination of compatible probes.

Designed to adapt to unique process control requirements, users have the option to enable or disable each channel independently.

Additionally, the HI-520 series introduces enhanced industrial control by operating a control-loop system whereby users have the option to run channel control either independently or configure to be triggered sequentially upon reaching the other channel's set point(s) (1, 2, or both). The device operates a logical channel with built-in mathematical functions.

This function is intended for when the controller works as an analyser for monitoring high/low parameter levels between two identical inputs with identical measuring configurations.

All the Universal Process Controllers (Hi-510 and HI-520) offer wall, pipe, and panel mounting options and feature a large backlit dot matrix display for easy viewing and provide an intuitive interface for setup options.

The controllers utilise multi-colour LEDs for easy viewing of the instrument’s status including relay activation, in alarm mode, or in hold status. All programming operations are done through the low profile vulcanised rubber keypad or with an RS485 connection to a supervisory computer.

Features Displayed on Screen – all models

Control Modes

The control mode can be configured to be On/Off, Proportional, or PID.

The mode can be set high or low. High control mode is required if the process value is too high and needs to be decreased. Low control mode is required if the process value is too low and needs to be increased.

For On/Off control, the hysteresis band is adjustable, while in Proportional and PID modes, deviation, control period, and other tuning parameters can be set to optimise control around a set point.

For HI-520, each channel can run control independently or sequentially.

Hold Function

During calibration, cleaning, and configuration the controller automatically goes into Hold mode. During Hold mode all control loops related are disabled. The analogue outputs may be configured to go to a fixed value or remain at the last value.

The Hold function can also be triggered manually, using an external digital input or by entering in Manual mode. This is useful for disabling control when performing maintenance.

Auto-Cleaning Cycle

Difficult applications often require an almost continuous maintenance of the probe. Processes with high-suspended solids, fats, oils, pigments, and micro-organisms will coat the pH sensing glass, ORP sensors, and the reference junction. The cleaning function allows programming of one or more wash cycles and uses the relays to activate valves, pumps or compressed air based on the type of washing that is required to maintain probes for reliable results.

Configurable Alarm System

The alarm system is configurable for measured parameters. The alarm can also be activated by event triggers or abnormal operation. For example, if a dosing relay remains closed for an excessive period of time or if temperature exceeds an upper limit during an exothermic neutralisation reaction. A blinking red LED signals an alarm state.

All relays configured for control are inactivated until the alarm state is resolved.

On HI-520 use channel configuration to setup and trigger an alarm.

LCD Information

Local visual indicators of measurement details as well as errors are displayed. The ? DIAG key provides details of the issue.

? DIAG - Help and Diagnostic Key

The help and diagnostic key (? DIAG) provides information related to errors; or in setup mode, information about settings.
