Usage Features
The ULTIMA controller is designed for user-friendly operation with its 7-inch touch screen interface, similar to a smartphone.
- Main Screen: Displays key parameters (TDS, ORP, pH, Inhibitor, Timers, Temperature) with current values, setpoints, and status indicators (e.g., power icon for relay ON, red padlock for lockout, flashing red for alarm).
- System Configuration: Accessed via the SYSTEM icon, allowing users to set preferences, date/time, language, and communication options (NONE, ETHERNET, WI-FI, MODEM).
- Screen Lock Password: Provides security by allowing password protection for controller access, with an option for Read Only mode.
- Import/Export Settings and Data: Facilitates easy transfer of settings and logged data to/from a USB drive.
- Component Settings: Each parameter (TDS, ORP, pH, Inhibitor, Dispersant, Timers, Outputs) has a dedicated screen for configuration, including:
- Control Mode: Selection of control strategies (e.g., TDS or Conductivity mode).
- Setpoint: Target values for controlled parameters.
- Pump Duty: Percentage of time the pump operates.
- Mode: Various operational modes (Disabled, Bleed, Continuous, Flow, Water Meter, Corrosion, etc.).
- Dose Type: Selection of dosing chemicals (e.g., Acid).
- Alarm Mode & Range: Configuration of alarm triggers and thresholds.
- Lockout Delay: Time delay before a component enters lockout mode.
- Dose Period: Frequency of dosing.
- Output Assignment: Ability to assign specific outputs to different components.
- Calibration: Supports both QUICK (using known pre-measured values) and PRECISE (using calibration solutions) methods for sensors (TDS, ORP, pH).
- Performance Chart: Provides historical data visualization (current day, week, or month) for component performance and dosing duty values.
- Timers: Six independent timers can be configured with names, assigned outputs, and various modes (Disable, Timer, Timer and Flow, Timer and Probe, Timer, Probe and Flow) for precise scheduling. Accessory timers allow for advanced sequencing (e.g., Pre-Bleed, Stop ORP, Bleed Lock out).
- Manual Dosing: Allows temporary manual override of outputs for priming pumps or testing, with countdown timers indicating remaining manual dose time.
Maintenance Features
The ULTIMA controller is designed for ease of maintenance, with clear guidelines for routine checks and sensor care.
- Sensor Cleaning and Calibration:
- Flow/Conductivity/Temp Sensor: Regular cleaning by abrading the sensor surface with wet-and-dry paper and ensuring the flow paddle is free from debris. Calibration is performed using pre-measured values or certified solutions, with temperature calibration recommended first.
- pH/ORP Sensor: Regular cleaning by rinsing with fresh water, gentle scrubbing, and soaking in Electrode Cleaner solution (AS9500). Precise calibration is recommended monthly and upon new probe installation, using buffer solutions (e.g., pH 4, pH 7) and ORP solutions (e.g., 250 mV, 475 mV).
- Routine Testing: The system's automatic dosing and control functions should be routinely serviced and chemically tested, with results logged, to ensure optimum performance and accuracy.
- Regular Inspections: Monthly inspections are recommended for:
- All sensors (inspection, cleaning, calibration).
- Flow sensors and wire strainers (checking for correct operation and debris removal).
- Injection non-return valves and pumps (cleaning and checking).
- Chemical suction and discharge tubes (inspection and replacement as necessary).
- Peristaltic Pump Maintenance:
- Squeeze tubes and roller blocks should be checked annually and replaced every 12-24 months. More frequent checks may be needed for higher pumping rates.
- Service kits (AP_PERI_S_KIT) and overhaul kits (AP_PERI_O_KIT) are available for pump maintenance.
- Chemical Injector Cleaning: Sodium Hypochlorite can cause scale formation, requiring frequent acid cleaning of dose injectors.
- Electrical Safety: The hazardous voltage area is protected by a cover. Only certified electricians or Aquarius Approved Service Technicians should remove the cover after disconnecting power. Fuses are easily accessible for replacement.
- O-ring Maintenance: Ensure the O-ring on the front lid is in good condition and properly seated to maintain the enclosure's integrity.
