The signal conditioner manages the input signals from the manual controls on the swing door. It converts those inputs into 4-20 mA signals before they are read by the I/O modules. Typically, this is used to open and close the valve from the panel, bypassing Opti’s online controls.

To minimize error from waves and other disturbances, the pressure transducer is protected in a stilling well. Questions? Email us at support@optirtc.com Opti Hardware O&M Manual: Continuous Control © OptiRTC, Inc. 2024. All Rights Reserved. Conﬁdential Information | Page 12...
Page 13: Power
Power Opti hardware can be powered by 120 V AC line power or a 24 V DC battery charged by a solar panel. If line powered, there will be a breaker nearby to disconnect power. If power is lost, a backup battery inside the actuator will move the valve to a predetermined failsafe position.

Page 15: Control Panel De-Energizing Procedure
Remote Manual Control A user with administrative permissions can override the Opti automatic controls of the valve using the online dashboard. Sign into the Opti web portal and navigate to the system control pod in the top left (Figure 6).

4. Once maintenance is complete, set the “local valve open” knob back to 0% open and turn the “valve control” switch to the remote position, so that Opti can continue to autonomously control the hardware. Local Manual Override with Hand Crank To physically operate the valve using the hand crank, follow this procedure: Follow the Control Panel De-Energizing Procedure to turn power off.

3. Put the valve in the fully closed position (0% open). When you can see the valve is fully closed, record the time. 4. Contact Opti Support and send the three recordings of time and target positions. Battery Back-up Failsafe Position Conﬁrmation The battery back-up failsafe position needs to be conﬁrmed during routine site visits.
Page 18: Winterization And Dewinterization
This is recommended for pressure transducers, TSS sensors, and multiparameter sensors, which may be damaged by freezing water. 3. Once you have locked the site again, notify Opti support via email or phone that the site has been winterized.

Place the site from manual mode into auto mode on the online portal. 6. Monitor the site for one week or until the ﬁrst rain event to ensure it is functioning correctly.
Page 20 Figure 7: Dependency ﬂow diagram Triggers for Maintenance By providing real-time data online on the Opti Dashboard, indicators of maintenance needs can be observed remotely. Please see below for some examples of unusual data patterns (observed on the Opti Dashboard) that indicate when maintenance is required: Valve Clog, Pressure Transducer Electrical Failure, and I/O Module Disconnection.
Page 21 Boston, MA 02114 1-844-OPTIRTC www.optirtc.com Figure 8: Opti dashboard during a valve clog Pressure Transducer Electrical Failure In this example, the water level sensor PT3 (orange) frequently spikes to the high end of its range (Figure 9). Since the sensor outputs an electrical signal, it appears that electrical components may be short-circuited.

The system needs to be energized and de-energized in a speciﬁc order to safely replace the batteries and protect system components, described below.
