Chapter 12 - Deflagration Control by Passive Isolationo 12.2.3 Flow Actuated Flap Valve

The EM-NRV meets all requirements of this section when installed with all options and conveying ductwork per 12.2.3.4.6

Key Points• 12.2.3.4.2 Requires a locking mechanism which is provided standard.• 12.2.3.4.3 Requires an Inspection door which is provided standard.• 12.2.3.4.4 Requires an immediate, automatic shutdown of the protected process. Accomplished with O-EM-

NRV-MS Microswitch which is an available option that mounts on the NRV locking mechanism and sends a signal upon an event.

• 12.2.3.4.5 and 12.2.3.4.5.1 requires a continuous signal to ensure valve operation is not compromised by the accumulation of a dust layer on the bottom interior of the valve and requires an immediate, automatic and orderly shutdown of the protected process. Accomplished with O-EM-NRV-DLS capacitive style Dust Level Sensor (DLS) which sends a signal when 0.15”-0.20” of dust has accumulated. The DLS is located in the air-stream and requires an intrinsically safe barrier.

• 12.2.3.5 Requires System Certification by a recognized testing organization. A.10.4.2.1 allows for European CEN ATEX certification being acceptable.

ATEX Certification

NFPA 69-2019 (A.12.2.3.4.6) STATES: The minimum design pressure for the ductwork is typically 2 x Pred because the pressure wave reflects off the closed valve. Depending on the distance between the flap valve and the

enclosure, pressure piling could further increase the expected peak pressure.** See Minimum/Maximum Distance Specifications

The NRV can be installed indoors, however the below statement from NFPA must be taken into account during the duct design process.

Mounting the Dust Level Sensor to EcoMAXX NRV

Step 1: Remove bolt on the bot-tom side of the NRV.

Step: 2: Install the first mounting flange onto the sensor. Note: The drawing below specifies the distances the first mounting flange should be from the top of the sensor.

Step 3: Insert sensor into the bottom side of the NRV and install second mounting flange on the sensor. Adjust height of the sensor to required height de-scribed in the drawing provided.

Dust Level Sensor -Recommended Installation Height

Dust Level Sensor with Mounting Flanges (O-EM-NRV-DLS)

Recommended Installation height of the first mounting flange. If the tip of the sensor is too close to the bottom surface of the NRV, the sen-sor will not function properly. Contrary, insert-ing the sensor too deep will result with interfer-ence from the flap valve. **26mm from the bottom surface of the NRV.

General Wiring Schematic for the EcoMAXX® Cp03

NOTE: On the wiring diagram you will notice there are two options provided for connecting to the main system control panel. One is an individual alarm configuration and the other is a general alarm config-uration. Choose the one that will work with your main system control panel. You will need to refer to your main system wiring diagram to determine how the connection needs to be made. See below for an en-hanced view of the 2 options.

To wire supply power connect line, ground, and neutral wires to terminals L, GND, and N as shown in the General Wiring diagram.

Page 16


Connect low voltage control wires to terminals 3 and 6 as shown in the General Alarm Configuration wiring diagram. Then use a jumper to connect terminals 4 and 5.

Connect low voltage control wires to terminals 3 and 4 as shown in the Individual Alarm Configuration wiring diagram. Then connect low voltage control wires to terminals 5 and 6 as shown in the Individual Alarm Configuration wiring diagram.

Page 17


Wiring the Microswitch to the EcoMAXX® CP03

Referencing the wiring diagram on page 15, the microswitch is connected using terminals 1 and 2. When looking at the diagram, notice only the black and grey wires are used for the microswitch connection.

Wiring the Dust Level Sensor to the EcoMAXX® CP03

Connect the black wire to one of the terminals labeled 1. Then connect the grey wire to the terminal labeled 2.

**On the wiring diagrams you will notice that the Dust Level Sensor will be installed inside the physical barrier inside of the

control Panel.**

Dust level sensor wiring must be in its own conduit.

Allen Bradley ISR: Connect the brown wire to terminal 1 on the intrinsic relay barrier. Connect the blue wire to terminal 3 on the intrinsic relay barrier.

Phoenix Contact ISR: Connect the brown wire to terminal 4.1 on the intrinsic relay barrier. Connect the blue wire to terminal 4.3 on the intrinsic relay barrier.

Page 18


General Wiring Schematic for the Cp04 (56004-031103)

Connect the brown wire to terminal 4.1 on the intrinsic relay barrier. Connect the blue wire to terminal 4.3 on the intrinsic relay barrier.

Wiring the Dust Level Sensor to the CP04

Wiring the Microswitch to the CP04Similar to the CP03, the black wire will land in the “24V+” terminal and the gray wire will land in the “1” terminal. Disregard all other wires from microswitch. (See below)

Jumper will be required between “24V+” and “2” (See Below)

System Interlock Via CP04Terminals “U1” and “U2” will be used as a shut-down signal in the CP04. When the CP04 is “OK” the interlock contact will be closed. The contact will open if any sensor faults. (Refer to above sche-matic)

Bypasssing the Dust Level Sensor for Inspection Protocol in the Cp04

In cases where an inspection protocol (NFPA 69: 2019, 12.2.3.4.5.2) is instituted in lieu of a dust level sensor for dust accumulation monitoring inside of an EcoMAXX NRV the following instructions must be followed to ensure the system remains running uninterrupted by a fault alarm.

1. Press the Up or Down arrow until your screen displays the system time and then press the “ESC” key.

2. The system menu will come up, scroll using the up and down arrows and press the “OK” key when you find “Program”.

3. Under the “Program” menu, select “Set Pa-rameter” by pressing the “OK” key.

4. Under the “Set Parameter” menu, select “By-pass DLS 1” and press the “OK” key.

5. Press the “OK” key until the word “Off ” flashes. Scroll using the up and down arrows and change to “On”. Press “ESC” when complete to exit all menus. Repeat steps 4 and 5 for DLS 2, 3, and 4 (if applicable).
