SERV-IS-LITE II/MB Longwall Lighting systems are designed for hard use
in the hazardous environment of an underground mine. The system provides safe, reliable,
low-glare, even illumination along the entire longwall face. This robust system, with
improved brass connectors, has been re-engineered to provide trouble-free operation in
harsh, wet conditions. SERV-IS-LITE II/MB has been evaluated by the Mine Safety and Health
Administration and meets the applicable requirements of Title 30 Code of Federal
Regulations, Section 18.68. This system is approved for use in Pennsylvania.

 | Brass, re-usable, staple-lok connections
|
| Near-ceramic, non-absorbing inserts
|
| Gold plated, constant contact pins
|
| Rugged #12/3 cable from power pack to luminaire
|
| Standard cable lengths simplify inventory requirements
|
|
|
| Our "MB" cabling connectors provide rugged, watertight, "mineduty" electrical connection
from our power-pack to the luminaire. The connectors are tested (pull-apaprt) to 450 psi
to ensure reliable operation. We can provide our
unique "Fault Monitor" at the end of the system providing improved phase loss
and short circuit protection. |
|
| Magnetic mounting option for tee
|
| In-line connector to join various lengths of cable
|
| End-mounted terminator ensures power integrity

The luminaire assembly is MSHA certified and
explosion-proof, but still rugged and lightweight. A special mirrored reflector and
improved solid-state circuitry provides more effective light output than our earlier
models. Individual lights can be replaced without turning the entire system off. The
Luminaire is designed to quickly snap in or out of the mounting base which saves time
during longwall moves or maintenance. This also allows the light to be borrowed to provide
illumination of nearby equipment. The fixture can be relamped at the face or in the
maintenance shop.
The standard mounting base includes two specially designed
retaining clips that lock the Luminaire into position. It fits the same bolt pattern as
our original SERV-IS-LITE II. Popular options are the dual or quad mounting magnets that
provide quick movement when needed, but also keep the lamp securely against the shield. |

Individual lights are powered by an intrinsically safe 12 Volt DC power
supply. Each supply is rated at 15 amperes and can feed four lights. The standard MSHA
explosion proof enclosure contains two power supplies. "Power On" and "12
Volt DC Output" LED indicators are provided to indicate the operational circuits.
They are visible through the enclosure cover plate.
The input power cable is supplied with SMC's field proven, MSHA certified,
explosion proof cable and gear mounted Lighting Connector Series. The receptacle has gold
plated Multi-lam inserts which provide multiple contact points, lower losses and trouble
free service. The mal plug is provided with a spring loaded index pin for easy alignment. |
For a fully integrated face electrical system, SMC offers a
5 ampere, 12 Volt DC, intrinsically safe power supply for use with Electro-Hydraulic
Shield Controls. This improved, "clean" power supply is highly regulated to
assure optimum performance for your electro-hydraulic system. It is designed to be
connected in series with the main power cable supplying the lighting system, eliminating
the need for a separate supply cable routed down the face. The circuit provides a constant
output through severe start-up and operating conditions.

The "MB" cabling
system was designed as an upgrade/retrofit for our standard SERV-IS-LITE II products as
well as for new installations. An existing system can continue to use the main power cable
for the power-packs, as retrofits are done to smaller sections of the lighting system. |
