The UV-eye scanner is designed to seal off the sight pipe up to pressures of 1 PSI (.07kg/cm

2

)

when the scanner lock nut is firmly tightened. Pressures in excess of 1 PSI (.07kg/cm

2

) should

be blocked from the scanner. A quartz lens coupling (Part #60-1290) or quartz window coupling

(Part #60-1257) may be used. Each is rated from -3 to +100 PSI max. (-.2kg/cm

2

 to +7kg/cm

2

max.).

9.

To increase scanner sensitivity, a quartz lens coupling (Part #60-1290) may be used. The quartz
lens permits location of the UV-eye twice the distance noted in Item 1. Use

Avoid sighting the spark — Resight scanner, shield between spark and scanner, or orifice to
reduce reflected signal from spark.

Typical Scanner Installations

Wiring of UV Scanners

The UV1A scanner is supplied with 3' (90cm) or 6' (180cm) of flexible cable. The UV-2 scanner is
supplied with 3' (90cm) of flexible cable. If it is necessary to extend the scanner leads, the following
instructions apply:

1.

Scanners without armored cable must be wired using metal cable or rigid conduit.

2.

High voltage wiring must not be installed in the same conduit with flame detector wiring.

3.

Selection of Scanner Wire:

a.

Use #14, 16, or 18 gauge wire with 90

q

C, 600 volt insulation for up to 200 feet (60M)of

distance. (approx. 20% signal loss at 100 feet [30M], 40% signal loss at 200 feet [60M]).

b. Asbestos insulated wire should not be used.
c.

Multi-conductor cable is not recommended without prior factory approval.

d. High voltage ignition wiring 

should not 

be installed in the same conduit with flame detector

wires.

The maximum UV signal 
from a flame is found in 
the first one-third of the 
visible flame taken from 
the point where the flame 
begins. The scanner sight 
pipe should be aimed at 
this area.
