OPTIDRIVE ECO HVAC
The Variable Frequency Drive for Fan & Pump Applications
KEY FEATURES
- Eco Vector Motor Control
- Energy Optimized Design
- Internal EMC Filter
- Low Noise Operation
A sensorless vector control for all motor types, including: IM (IE2 & IE3 Induction Motor), PM (AC Permanent Magnet Motor), BLDC (Brushless DC Motor), SynRM (Synchronous Reluctance Motor), and LSPM (Line Start PM Motor).
Optidrive Eco provides efficient, reliable, and quiet control of motors for HVAC and pumping applications.
Optiflow multiple pump control technology is just one in a series of specialist features in this drive dedicated to energy efficient, flexible pump control.
Optidrive Eco HVAS variable frequency drives not only feature innovative every saving features.
HVAC Building Services
Optidrive Eco has a PID controller built in that is fully integrated with both HVAC and energy efficient features and is packaged in a user-friendly way to ensure ease of use and fast commissioning. Now, in the majority of applications, it has become possible to eliminate the need for external controllers.
Coordinated fan station control built-in to each Optidrive Eco as standard allows independent control in multiple fan or fan bank applications.
KEY FEATURES
- All drives operate as variable speed for maximum energy saving.
- Equal run time sharing across each fan / fan bank.
- Automatic system reconfiguration in the event of a fan fault.
- Continued system operation when drives are individually powered off.
- Communication and +24V control voltage shared between drives via a standard RJ45 patch lead.
- Independent maintenance indicators for each fan bank.
- Any fan bank can be switched to Hand operation at the touch of a button and will automatically rejoin the network when switched back to Auto.
- For belt driven fan applications each fan can be set for belt break detection.
- Optional mains isolator with lock off for safe system maintenance.
- Drives configured through simple parameter set-up and intelligent drive self-configuration.
Advanced Pump Control
KEY FEATURES
- Total Control–A single ‘Master’ drive acts to control and monitor system operation. Control connections are made to this drive only, saving installation time and reducing costs.
- Simple Connection—Additional drives connected on the system require a single RJ45 connection and basic commissioning, leading to time savings and simplified installation.
- Flexible Solution—The system can operate with up to five pumps in any configuration, e.g. Duty / Assist / Standby. Duty pumps are automatically rotated, ensuring maximum service life and system efficiency.
- Consistent Flow—The required pressure and flow levels are maintained regardless of how many pumps are required. When demand increases, additional pumps are automatically brought on stream to assist and are switched off again when not required.
- Reduced Downtime—In the event of a fault, or if a pump needs to be isolated for maintenance, the system will automatically continue to operate with the remaining available pumps. The mains power can even be completely isolated from the Master drive without affecting operation of the Slave drives.
- Blockage Detect/Clear—Optidrive Eco can detect pump blockages and trigger a programmed cleaning cycle to automatically clear them, preventing downtime.
- Dry Run Protection—Optidrive Eco can evaluate a pump’s speed/power and shut it off or warn when the pump starts to run dry, protecting it from heat/friction damage.
- Motor Preheat Function—Optidrive Eco features a motor preheat function to help ensure moisture is not permitted to collect on the motor in periods of inactivity and prior to motor start up. In addition, the motor preheat function can be used to keep condensation from developing on the motor as the motor cools down immediately following a stop. The feature is fully configurable, meaning the pump can be always available the instant it is required.
- Pump Stir Cycle—Triggered by a settable period of inactivity, a configurable cleaning cycle can be run to clear sediment, ensuring the pump is ready to run when needed.
- Drive Controlled Bypass—Optidrive Eco can operate as a bypass controller when installed as part of a bypass circuit. Activation of Bypass mode can be determined intelligently by the Optidrive Eco drive based on a command from the building management system. Additionally, the drive can be set to automatically select bypass mode when entering a trip condition ensuring minimal disruption to service.
Pump prime mode allows starting of the pump in a safely controlled manner, to ensure consistent filling and pressurization of pipe work and systems. Low pressure warnings are ignored during priming to allow the system to prime correctly, whilst a failsafe timeout prevents the pump from continuing to run in the event of a failure to prime. This helps to prevent the effects of water hammering (such as bursting water pipes) or damage to fountain / sprinkler heads.
The time limit, set for pump prime mode to complete, means that the pressure in the system must reach the minimum level within the set time. Failure of the system to pressurize would indicate a leak or burst pipe within the pump system and result in the Optidrive Eco shutting down the pump. During normal operation the system pressure is still continuously monitored against the minimum level so that a burst pipe during normal operation will likewise result in the drive tripping ‘low pressure’ and shutting the pump down.
- All drives operate at variable speed for maximum energy saving.
- Equal run time sharing across every pump.
- Automatic system reconfiguration in the event of a pump fault (including the master pump).
- Continued system operation when drives are individually powered off (including the master drive).
- Communication and +24V control voltage shared between drives via a standard RJ45 patch lead.
- Independent maintenance indicators for each pump.
- Any pump can be switched to Hand operation the touch of a button and will automatically rejoin the network when switched back to Auto.
- For wastewater applications each pump can be set for blockage/ragging detection and activate an automatic de-ragging/pump cleaning cycle.
- Optional mains isolator with lock-off for safe pump maintenance.
- Optiflow function configured through simple parameter set-up and intelligent drive self-configuration.
