5.11 ELECTRIC NOZZLE ACTUATOR WIRING
The electric RC monitor is designed to control and is factory wired for a TFT electric actuated nozzle. Task Force Tips nozzles are
available with a male cord plug. After mounting the appropriate nozzle onto the monitor, plug the male cord from the nozzle into the
female cord located on the outlet of the monitor. Make sure the two coupling nuts are tightened securely to ensure a proper watertight
seal.
If retrofitting an existing TFT nozzle, a male cord plug (TFT #Y5480) can be purchased and installed in place of the existing actuator
cord. Please consult factory for installation.
5.10.3 ELECTRONICS ENCLOSURE WITH AT STOW RELAY
The electronics enclosure provides feedback for the user that the monitor is in the AT STOWED position. This electronics enclosure
contains a circuit board that is equipped with a relay that is energized when the monitor is in use and de-energized when the monitor
reaches its final STOW location. The contact rating of the relay is 1 amp @ 30VDC for resistive loads and 0.2 amps @ 30VDC for
inductive loads.
The AT STOW relay has one Form-C contact (common, normally open, normally closed) that can be used. The figure below shows the
terminal blocks available for user wiring.

6.2.1 OPERATOR STATIONS
6.2.1.1 MONITOR MOUNTED OPERATOR STATION
This operator station is factory installed on the monitor and is used by personnel right at the monitor.
6.2.1.2 PANEL MOUNT OPERATOR STATION (Y4E-RP)
This operator station is installed on the truck, for example the pump operator's panel. It is used to operate the monitor from a location on
the truck.
The electric Tornado RC monitor has five different styles of operator stations for use in various locations on the fire truck or fire ground.
The design of the operator station communications allows users to override commands on other stations. The "last" button pressed has
control. The overridden user can regain control by releasing his/her button and pressing again.
Platform and ladder electronics enclosures are pre-configured for one set of inputs to have a master override feature. The operator
station connected to these inputs, typically at the base of the ladder, will override any other operator station.
Any operator station with a communication board or connected to a communication board can be field configured with the master
override feature. This allows the user to setup an operator station on the fire truck or fire ground as the master override station. See
Section 6.2.2 for details.
6.1 OVERRIDE HANDWHEELS
In the event of electrical system failure of the monitor or fire truck, Tornado RC is factory supplied with handwheels so the monitor may
be manually operated.
