Mounting Range Of Companion Flange; Items Required For Adjustment Test - Fuji Electric ZSS-8 Series Instruction Manual

4.3 Mounting range of companion flange

Mount the companion flange so that it satisfies the conditions of the following figure (Fig. 4 － 2). If the con-
ditions below are not satisfied, light cannot be received even if the light axis adjustment is performed by the
angle adjustment unit. In such a case, mount the companion flange again.
When θ (angle determined by laser light source and flange diameter) is bigger than 5°, mount the companion
flange within the angle γ (≤ 5°) inside the circle with radius A.
When the distance between laser light source and stack is long, or θ angle is less than 5° because flange di-
ameter is small, both radius A and angle γ will become smaller, and the mounting conditions will be strict.

4.4 Items required for adjustment test

It is recommended to prepare the following items for the adjustment test before installation.
(1) Cable between receiver unit and control unit (for calibration)
(2) Cable between receiver unit and transmitter unit (for calibration)
(3) Calibration gas cell
(4) Power supply drum (or power supply extension cable)
(5) Digital multimeter
(6) BNC for light axis adjustment (ZZP ＊ ZSSTQ505298)
(7) Flow meter (about 2L/min)
(8) N Gas cylinder

(9) Gas cylinder corresponding to the span (80 to 100% of span)
(10) Regulator (for gas cylinder) (For HCl/NH
regulator, use it only once and then discard it. A brass regulator may get rusty inside, and the rust
absorbs gas to disturb accurate measurement.)
(11) 10/8 mm PTFE tube, 10 m (we recommend to prepare the tube with some extra length)
(12) Rc1/4 × 10/8 joint, two or more
(13) Tools (2 spanners, measure, cutter, Phillips screwdriver, flat-blade driver, hexagonal wrench, tube
cutter)
(14) Plastic sheet (used to prevent the drop of parts and/or tools)
