MONITOR

BoaX2™ 2000 Monitor - 7451X2

The BoaX2 2000 monitor is a cast aluminum monitor with 4”

waterway.The waterway contains a central vane to minimize

large-scale turbulence and provide superior ﬁre streams.The

water supply connection is a 4”-150# ANSI ﬂange.The discharge

nozzle connection is a 3 1/2” National Hose male thread.

High power, permanent magnet variable speed DC gear motors

that drive the left-right and up-down monitor motions are NEMA

4 rated for use in harsh environments. The monitor utilizes the

EXM2 control platform and can be controlled by hardwired input

devices via CAN bus or by an optional upgraded Radio Frequency

(RF) device.The monitor may be powered with 12 or 24VDC.

An optional electric valve is available to allow the user to control water ﬂow directly from the

EXM input device.

When using the BoaX2 2000 monitor in a horizontal travel range in excess of 90 degrees to the

left and 90 degrees to the right of the monitor center position, Keep-Out Zones must be used. The

monitor horizontal center position is located at the center of the metal nameplate. Setting a left

and right Keep-Out Zone is required to ensure that interference between the discharge elbow and

horizontal motor and sensor geometry is prevented. Failure to use Keep-Out Zones as described

can result in damage to the monitor. Refer to the Operating Instructions section for more on

setting Keep-Out Zones.

A left and right Keep-Out Zone are factory set at Elkhart Brass so that the monitor discharge

elbow and stream shaper do not contact the horizontal motor and sensor geometry. If the

monitor is recalibrated or if these Keep-Out Zones are removed, new Keep-Out Zones orTravel

Limits must be set to prevent potential interferences between these parts.

CAUTION: All EXM2 monitor motors are 12VDC. If using a non-EXM2 nozzle,

another 12VDC nozzle should be used, or nozzle control may not function properly.

CONTROL

Joystick Controller – 7030X2

The Joystick Controller can be mounted inside the apparatus cab to control

all monitor functions, including oscillation, stow and deploy.The monitor

direction (both vertical and horizontal movement) is changed by moving

the joystick in the desired direction of travel. The up-down and left-right

motions can be operated simultaneously with pressure sensitive speed,

moving the monitor faster or slower depending on how far the joystick is

pushed and pulled. The water valve can be opened with a trigger switch

located on the front of the joystick or can be locked into position through

the use of the valve buttons on the joystick. Nozzle pattern can be changed

using the thumb wheel on the top of the joystick. Oscillation is programmed

by using the joystick in conjunction with the oscillate button.

Panel Mount Controller – 7010X2

The Panel Mount Controller is a sealed controller for operation of the

monitor, nozzle, and water valve (optional). Separate push button switches

are provided for up, down, left, right, fog and straight stream, valve open,

valve close, valve preset, stow, deploy, oscillation, and auxiliary functions.

The Panel Mount may be powered with 12 or 24Volts.

Handheld Controller with Docking Station and RF to CAN gateway – 7015X2

The Handheld Controller is a sealed remote control that contains all the

controls necessary for operation of the monitor, nozzle, and water valve

(optional).The handheld (7015X2WH) is paired to a RF to CAN gateway

(7015X2 GW) and has a docking station (7015X2 DS).The handheld allows

the operator to control the monitor from a signiﬁcantly improved point of

view, allowing the operator to conﬁrm that they are hitting the desired target.

Separate push buttons are provided for up, down, left, right, fog and straight

stream, valve open, valve close, valve preset, stow, deploy, oscillation,

and auxiliary functions.The 7015X2, through the use of frequency hopping

techniques, allows multiple transmitters to operate on a common site

without interference. The remote also has an automatic power down feature

that will shut down the power after 5 minutes of no activity. As an additional

power saving feature, the radio signal is only transmitted while buttons

are pushed.The handheld remote case has a NEMA 4 rating.The Handheld

docking station may be powered with 12 or 24Volts.

!Caution: Any modiﬁcation of the Joystick, Panel Mount, or Handheld Controller

enclosures will destroy the NEMA 4 rating to that piece of equipment and will void

the warranty coverage.

MONITOR & VALVE ACCESSORIES

Position Feedback Display – 7051X2

All EXM2 monitors come with Absolute Position Feedback sensors.These

sensors provide constant feedback to the monitors’ processor even when the

monitor is moved via manual override. This information is then transmitted

to the Position Feedback Display.

Unibody Valve with E14X (E16X for EB6D) Electric Actuator

The Unibody water valve provides a convenient remote on/off and preset

valve positioning control of the water supply to the EXM2 monitor.This

allows the operator complete control of the unit from the safety of the vehicle

cab or handheld radio controller*.The water valve motor speed prevents

water hammer, yet closes quickly enough to help preserve the limited on-

board water supply.The electric actuated UnibodyValve may be powered

with 12 or 24Volts.

*Valve must be wired for CAN communication with a RF to CAN gateway.

INSTALLATION INSTRUCTIONS

Recommended electrical requirements for BoaX2 2000 monitor:

Distance Ft.(m) Wire Gauge (AWG)

100(30.5) – 150(45.7) 8

50(15.2) < 100(30.5) 10

25(7.62) < 50(15.2) 14

< 25(7.62) 16

• Power and Ground wire type: Cross Link or equivalent (Must meet or exceed NFPA 1901 Section 13)

• Maximum monitor amperage draw: 20 AMPS (35 AMPS for FoamTube Expansion)

• CAN wire gauge and length:

• Main Line: 131 ft. (40 m) – 18-20 AWG (Must meet J1939 speciﬁcation)

• Monitor is terminated and must be at the end of the main CAN line

• CAN wire type and shielding:Twisted shielded pair - 105°C 150V (Belden 9841 series or equivalent)

• Shield Drain: Connect shield/drain to pin C of J1939 connector

Recommended electrical requirements for the EXM2 series input devices:

• Power and Ground wire gauge and length: 18-20 AWG 105°C 150V up to 150 ft. (45.7 m)

• Maximum input controller amperage draw: 500mA

• CAN wire gauge and length: 3 ft. (1 m) – 18-20 AWG

• CAN wire type and shielding:Twisted shielded pair - 105°C 150V (Belden 9841 series or equivalent)

• Shield Drain: Connect shield/drain to pin C of J1939 connector

WARNING: Turn off system power before connecting or disconnecting an

EXM2 component.

Termination Points

When using CAN lines for communication there must be 2 termination points within the system. The monitor

should be considered one of these terminating points and located at one end of main CAN line. Termination

points are explained further in the Conﬁguration section (installation step 2). What is important at this time

is that in order to maximize the efﬁciency of communication in your CAN network, you must terminate the

component located at the opposite end of the main CAN line. This should be taken into consideration as

you setup your EXM2 system. Each additional EXM2 component that requires connection to the main CAN

communication line between the two end components will require the use of CAN Splitter (P/N 24196000).

The maximum length of wire from the main CAN line is 3ft. and would be considered a branch (node) off the

main CAN line. A CAN termination plug (P/N 24197000) and CAN splitter (P/N 24196000) may be required to

terminate the EXM2 component at the opposite end of the CAN line from the monitor.

INSTALLATION STEP 1: Mount and Wire All System Components

Installation instructions have been included for all EXM components.

BoaX2 2000 Monitor –

•

Before mounting the BoaX2 2000 monitor, ensure that space allows for monitor to

move through the intended range of motion. Disconnect all electrical connections.

• The horizontal center of the monitor is marked by the center of the

nameplate.The monitor is factory calibrated to move equally to the left and

right from this center point.

• Mount the monitor onto an appropriate ﬂat face ﬂange with eight (8) 5/8-11 UNC grade 5, carbon steel

or stainless steel bolts & nuts. Seal ﬂange joint with an appropriate full face gasket. Install eight (8) 5/8”

ﬂat washers onto the monitor

ﬂange side of the connection.Torque bolts uniformly (20 ft-lbs at a time in a

crisscross pattern) to 60-70 ft-lbs.

Apply blue Loctite 242 or equivalent to the threads.

• The monitor will use a CAN line to communicate with other EXM2 components. Connect the monitor

pigtail 1 to CAN bus.

• Supply power to the monitor by connecting the two red and two black leads from the 8 pin connector

to an appropriate power source. Install one 20 Amp fuse in line to both positive power leads for a 12V

system (10 Amp for 24V system) to protect the monitor electrical components. Be sure the wire gauge is

large enough to prevent a voltage drop under load.The voltage at the monitor needs to be 11V or higher

during operation.

Be sure the ﬁnal wire size is appropriate for the connector. An OEM-supplied waterproof junction box or

splice installed close to the EXM2 monitor may be needed to reduce wire size prior to making the ﬁnal

connections. Refer to recommended electrical requirements for EXM2 monitor on page 8.

• Refer to the respective plug ﬁgures for information on the plugs’ pins.

1 2

WARNING: When installing the monitor on a raised face companion ﬂange, it

is critical that the bolts be tightened uniformly to prevent misalignment of the

monitor relative to the ﬂange or valve. If the monitor becomes misaligned, the

base ﬂange will fracture and fail when the bolts on the “high” side are tightened.

CAUTION: Do NOT use motors or discharge as leverage to tighten monitor.

Stow Output:

The EXM2 monitor provides one electrical output to which an OEM can connect to in order to

enable/disable truck operations based on whether an EXM2 monitor is stowed or not stowed.This

could be used, for example, for a truck that has an aerial or other movable object that may hit the

monitor if moved when the monitor is not stowed.These outputs could also be used to turn OEM-

supplied indicator lights on or off depending on the monitor stow state.

• Disconnect monitor power and locate the Power/CAN connector provided with monitor.

• Remove the position 5 plug from the Power/CAN connector.

• Remove the wedge lock from end of the connector.

• Insert the contact end of stow output wire P/N 37241063 into position 5 until it snaps into place.

• Reinstall the wedge lock into the end of the connector.

• Connect the stow output lead to the customer-supplied relay device that the Stow output switches.

• The stow output provides a ground to this lead when the monitor is not stowed, and provides an

open circuit, otherwise.

• The stow output is limited to 250 mA of current switched to ground (when the monitor is in a

non-stowed position).

• The stow output handles up to +28VDC when open circuit.

• The stow output maintains the switch state when the monitor is powered off.

Proximity Sensor for Extended Travel:

An OEM supplied proximity sensor is used only for extended travel functionality and is not

necessary for standard monitor operation.

The Cobra EXM2 is capable of vertical extended travel beyond the calibration point (straight up).

An additional ground input is needed to enable this functionality.This functionality is intended to

allow an OEM supplied proximity sensor to be used to enable or disable extended travel when the

monitor is used with aerial applications.The proximity sensor should provide an open circuit under

normal operation, and a ground when the monitor can move into the extended travel region.

• Disconnect monitor power and locate the Power/CAN connector provided with monitor.

• Remove the position 4 plug from the Power/CAN connector.

• Remove the wedge lock from end of the connector.

• Insert the contact end of the proximity sensor wire P/N 37241000 into position 4 until it snaps into

place.

• Reinstall the wedge lock into the end of the connector.

• Reconnect connector and conﬁgure the EXM2 system for extended travel functionality before use.
