Frequently Asked Questions

CUBEx Intrinsically Safe Lights (printable)

  1. What are the recommended applications for CUBEx IS Lights?

CUBEx IS Lights can be used in Longwall, Development and RTVs

Use as a floodlight, spotlight, traffic light, hazard light, or as a soft barrier in No-Go Zones

  1. How often do CUBEx IS Light components need to be overhauled?

As the IS Lights are Ex ia, we recommend inspection and/or overhaul every 6 years. This can result in considerable compliance cost savings compared to the standard 4-year requirement

  1. Can all the IS CUBEx components be overhauled/refurbished?

LIM (Light Interface Module) and Lights are returned if they pass our inspection and testing. PSM/PSL (Power Supply Module/Local) may be overhauled if required.

  1. What plugs are available for IS Lights?

Molex – IP 67 plastic connector (automotive plug) which was part of the first release of IS Lights. We recommend that you upgrade to the Amphenol or Metal plug

Metal Plug – Robust IP 67 stainless-steel connector

Amphenol – IP 67 connector with a “pigtail” cable for easy connect and disconnect. This is available with tethered dust caps, which are  especially useful on Longwall applications

  1. How much power does the CUBEx IS Light draw?

Generally, 600 mA at 12 VDC but can consume as little as 300mA. It is flexible enough so the brightness can be adjusted from 5% up to 150% of standard output – which can be set by NAUTITECH® during the initial manufacturing process

  1. How many lights can I power using ONE CUBEx Power Supply for Lights (PSL)?

Up to 32 lights at 50% brightness. Up to 16 lights  at full brightness

  1. What is the maximum cable length we can run from a Nautitech PSM/LIM?

Standard length is 30 metres but longer lengths are possible in certain situations.

  1. Can the individual IS Light be programmed/adjusted on the machine via a remote?

Controlling and signalling of individual IS Lights can be done via Bluetooth by programming the LIM from your laptop. Individual banks can be turned ON or OFF to adjust brightness.

  1. Can I get a Pigtail longer than 1m?

No, but an extension cable up to 30 metres can be plugged into the pigtail

Methane Master CH4 System (printable)

  1. Can the CH4 fitting and connector assembly (brass sensor assembly) be overhauled?

NO. This item can only be replaced

  1. Is the Ch4 stainless snout a flameproof component?

NO. Please refer to CH4 Assembly Matrix HERE

  1. What version of Hawkeye software am I running?

View it on the first screen after powering up the unit or access via the Hawkeye menu

  1. How do I tell if the heater is working?

You can determine this by feel (heat) or by using a current (Amp) meter. Consider installing the Spitfire® DataMaster for continuous, real-time monitoring.

  1. Do the Rev 3 batteries require an inline fuse for the heater connection?

Inline fuses are NOT required as the Rev 3 battery utilises an internal resettable circuit breaker

  1. What is the recommended overhaul/replacement period for the 7.2V battery?

NAUTITECH® recommends that you replace the battery after FOUR years in service

  1. How can I tell if my CH4 sensor has the latest software?

  1. Can I enable/disable Profiler in Hawkeye?

Access through “configuration panel” mode to enable/disable the Profiler (menu item 3.5)

  1. Can I enable/disable info and warning messages in Hawkeye?

Access through “configuration panel” mode to enable/disable messages (menu item 3.6)

  1. Does the 5-channel barrier need to be connected to Battery IS 0V Stud?

YES

  1. Why is my machine always displaying Override Mode?

Check if the external pressure switch is stuck in the closed position (ON). NAUTITECH® recommends replacing external pressure switch.

  1. Why doesn’t my Date and Time work in my Hawkeye?

Date & Time are only available with the 7.2V Rev 3 Battery which includes a Real Time Clock (RTC)

  1. Can my RTDs be overhauled/recertified?

YES they can be returned to our factory for OEM repair

  1. How often do I need to replace my C9 engine sensors?

Every 4 to 6 years

  1. What serial number do I use for the Hybrid Snout as there are 2 different stickers?

The Methane Master has gone through several changes over the past few years.

Hawkeye Quad Displays and IP Cameras (printable)

  1. What are the recommended applications for the Hawkeye Quad (HEQ)?

HEQ can be used on Development Equipment and RTVs as a SMART Display which assist with recording, data storage, and video playback. See Product Information Card HERE

Our latest application, called Redbolt, detects frictional ignition hazards and “hot” objects which may include roof bolts, rib dowels and shearer picks.

  1. What are the recommended applications for the NAUTITECH® HD and Thermal Cameras?

Longwall, Development, Diesel machines, Belt Conveyors and other heavy industrial use.

  1. How do I change out a camera on a Hawkeye Quad 7” Display (HEQ)?

  1. What’s the recommended cable length for Spitfire®?

Recommended length is less than 500 metres.

  1. What is the difference between a Spitfire® and a Super Spitfire?

Spitfire® is the modem fitted on a machine to convert input data for transmission over a powerline cable. On the receiving end, another Spitfire converts the signal back and connects through a network switch to the LAN. This allows it to transmit data between equipment and the surface.

The Super Spitfire is a repeater which can extend the range of the Spitfire® powerline network

  1. Does the Wingman need to be on the same layer (layer2) as the Spitfire® devices?

YES

  1. Do I need to twist the Red Pair together on the Capacitive Coupler?

YES
