Preparation for use

Perform the following steps to prepare and install the flame detector.
The installation sequence might vary according to the physical
structure of the site.
1. Install the flame detector:
Mount the tilt mount (see chapter 3.3.1 on page 12).

Attach a conduit connection or cable gland to the flame

detector (see chapter 3.3.2 on page 12).
Attach the flame detector to the tilt mount (see chapter 3.3.3

on page 12).
Wire the flame detector (see chapter 3.3.4 on page 12).

Mount the weather cover (see chapter 3.3.5 on page 13).

Orient the flame detector (see chapter 3.3.6 on page 13).

2. If required, adapt the configuration of the flame detector (see
chapter 3.3.7 on page 13).
3. Power up the flame detector (see chapter 3.3.8 on page 15).
4. Test the flame detector (see chapter 3.3.9 on page 16).

3.3.3

Attaching the flame detector to the tilt mount

► Illustration on the fold-out page (Figure C)
1. Place the flame detector with its cable entries pointing downwards
on the holding plate of the tilt mount (C-2).
2. Secure the flame detector to the tilt mount with the screw and a
spring washer using a 1/4" hex key (C-3).
3. Secure the flame detector with the locking screws (C-4, C- 5) using
a 3/16" hex key so that the flame detector can be wired.
3.3.4

Wiring the flame detector

For wiring, use color-coded conductors or suitable wire markings or
2 2
labels. 0.5 mm to 3.5 mm (12 to 20 AWG) wires may be used for site
wiring. The selection of wire gauge should be based on the number of
flame detectors used on the same line and the distance from the
control unit. For more information, please refer to the Technical
Manual.
► Illustration on the fold-out page (Figure B)
1. Make sure that the system is disconnected from the mains.
2. Remove the back cover by removing the 3 screws using a 3/16"
hex key (B-1).
The terminal board is now revealed.
3. Pull the wires through the cable entry.
4. Connect the wires to the corresponding terminals (see chapter 7.2
on page 21) on the terminal board using a 2.5 mm flat screw
driver.
5. Connect the earth wire to the earth screw (B-2) using a 6 mm flat
screw driver. The flame detector must be well grounded.
6. Check the wiring. Improper wiring may damage the flame detector.
7. Check the wires for secure mechanical connection and press them
neatly against the terminal to prevent them from interfering while
closing the back cover.
8. Place and secure the back cover by screwing the 3 screws in the
cover bolts (B-1).
9. Perform a continuity test.
