TYPICAL UV SCANNER INSTALLATIONS
The figures on the next page show different mounting instructions, taking into account the maximum
scanner temperature of 100°C
— Standard mounting
— High temperature mounting
— High pressure/temperature mounting
Note: 1“TEE pieces are not available from Fireye; they must be purchased locally.
SCANNER WIRING
Like other FIREYE controls, the FIREYE FLAME MONITOR is protected against short-circuited
scanner input terminals. Following recommendations apply for scanner control wiring:
•
Keep scanner wiring as short as possible
•
Use wires rated for scanner voltage and its ambient conditions (temperature, humidity, oil resis-
tant, flame retardant, etc.).
•
Do not run scanner wires in the same conduit as other electrical wires.
•
Avoid wire loops and false groundings.
•
Do not ground any scanner wire.
Infrared scanner wiring
Infrared scanner type 48PT2 is provided with a flexible conduit. The two wires are to be connected to
a coaxial cable via a junction box. Maximum cable length between scanner and control is 30 meters.
Ultra-violet scanner wiring
Self-check scanner 45UV5.
The self-check scanner has four wires 1800mm long.
•
Two black wires, providing power to shutter drive circuit, to be connected to terminals Ll and N
•
Two red wires for flame signal, to be connected to terminals Sl and S2.
Scanner voltage:
•
Terminals Sl-S2 600 VAC
•
Terminals Ll-N: Line Voltage above ground:
For extended wiring use standard four conductor cable rated for 600V to be connected via junction to
scanner wires. Maximum cable length 50 meters (150 feet).
Other UV scanners
These scanners (UV1A3, UV1A6, UV2, 45UV3) are provided with two wires. Use standard two
conductor cable, rated for 600V, to obtained extended wiring via a junction box. Maximum cable
length 50 meters (150 feet).
