2 Dimensions FN.0.2 / FN.0.4 / A FN.1.2 / FN.1.4 (with failsafe) A A = mm B = mmm C = mm B A = mm B = mm C = mm B adaptor: BWMA520 C adaptor: BWMA520 C Mechanical Installationn Correct mounting Incorrect mounting 1. The actuated valve installation should be easily accessible and provide sufficient clearance for servicee and replacement. 2. Horizontal and vertical positions are preferred orientation for the installation of actuated valve. However, this actuator can be installed at any in between angle. Caution: Do not install at more than 90º from horizontal. KNOB MANUAL OVERRIDE FORCE LIMITING ADAPTOR (MA500) 1. Ensure the actuator is disengaged from the valve adaptor. To do so, press the release button while turning the actuator CCW 30º. 2. Mount the valve adaptor to the valve and finger- tighten only. 3. Rotate knob counter clockwise (CCW) to open the valve. Do not force knob in either direction! 4. Manually adjust the knob to test piping network. 5. Once satisfied that the network is working properly, engage the actuator over the valve adaptor and turn 30º clockwise (CW). You should hear an audible click. To disengage the actuator, press the release button while turning the actuator CCW 30º. Caution: The actuator is specifically calibrated to its adapter. Do not exchange original adapter with a different actuator. WARNING! You must connect the actuator to its adaptor and mount it on a valve before applying power. Failure to do so will result in incorrect operation of the actuator. If you plan to add foam insulation, do not add insulation foam beyond the chrome ring and around the adaptor. Improper installation of insulation material could lead to a build-up of condensatee water around the valve and the chrome ring of the adaptor, which could lead to build up of rust and compromise the structure of the chrome ring that holds the adaptor. Caution We strongly recommend that alll Neptronic products be wired to a separate grounded transformer and that transformer shall service only Neptronic products. This precaution will prevent interference with, and/or possible damage to incompatible equipment. Page 2

3 Wiring: Analog Models FN.0.2 & FN.1.2 Analog 500 Ohms Optional: Add 500 Ohms resistor (1%/0.25W) between BLK and WHT to use 4-20mA control signal. DIP switch 3 must be set to OFF ANALOG SIGNAL FEEDBACK Wiring: Digital Models Please note that the following wirings are shown for the Normally Closed (rotation direction). With the normally open setting, the red wire becomes open and the white wire becomes closed. FN.0.4 & 3-wire / Digital 2 positions FN.0.4 & 3-wire / Digital 3 point floating FN.0.4 = = Vac FN wire / Digital 2 positions FN wire / Digital 3 point floating DIP Switches Each model has a different number of DIP switches, which are located behind the translucent silicon cap at the back of the actuator. Please read the following sections carefully for detailed information on the options. DIP switches can be changed at any time. The changed option (DIP switch setting) takes effect immediately. If a change is made during an Auto-Stroke sequence (analog models only); the change takes effect once the Auto-Stroke sequence is complete (up to 240 seconds). Settings: Analog Models Auto-Stroke Analog actuators perform an Auto-Stroke sequence upon every power up. The Auto-Stroke sequence runs from 0 to the end position and back in order to automatically detect the stroke limits and calibrate the input signal to the detected stroke limits. The Auto-Stroke sequence can take up to a maximum of 4 minutes to complete. During the Auto-Stroke sequence the status LED remains on and the actuator will not perform any other action. If the actuator and/or adaptor are removed from the valve after initial installation, you must initiate an Auto- Stroke sequence to recalibrate the actuator. To do, remove power and reapply power Anti-Stick Option If activated, the actuator makes one full cycle every day if no action or motion has been applied in the last 24 hours. This operation clears up any possible impurities accumulated on the plug and seat of the valve. Activate the Anti-Stick option by setting DIP switch #2 to the ON position. During the Anti-Stick cycle, the actuator will not react to a control signal. Do not activate the Anti-Stick option in case of incompatibility with your application. Page 3

4 Settings: Analog Models FN.0.2 (Analog) FN.1.2 (Analog with Fail Safe) Rotation Direction The motor direction of the analog actuators is reversible. By default the actuator is set to reverse acting (DIP switch #1 = ON). Reverse Acting (default) DIP Switch #1 = ON Direct Acting DIP Switch #1 = OFF Enerdrive* Fail Safe System The Enerdrive* system is a patented method of storing energy (using super capacitors) that is later used drive the actuator to its failsafe position during a power failure. It takes approximately 90 seconds to fully charge the Enerdrive* system. With the restoration of power, the actuator immediately resumes operation and the Enerdrive* system is recharged. Use DIP switch #2 to set the actuator to respond according to the application requirements. Fail Safe Direction Final position during fail safe operation Page 4
