FIGURE 15.
INSIGHT II CABLE CONNECTOR, Female Pin Orientation
QUICK DISCONNECT PINS
1. Flame relay contacts are shown in de-energized (no flame).
2. Fault relay contacts are shown in de-energized (fault condition).
3. Fireye recommends that the FAULT RELAY contacts MUST be
wired in series with the Flame relay contacts for maximum safety
applications.
4. Connect cable shield to earth ground at power source.
5. BMS = Burner Management System (by others).
6. External 0.5 Amp slow-blow fuses recommended.
7. A ground screw is provided on the scanner body. An external
ground wire may be required by local codes.
8. The scanner's 4-20 ma output is internally powered and must be
connected to a passive (voltage-free) device. Do not connect to an
externally powered 4-20 ma loop or the scanner may be damaged.
9. The return (-) for the customer's 4-20 ma device may be connected
to either scanner pin 6 or pin 8.
10. With Remote File Select programmed as “LINE”, external
switches SW1/SW2 (not furnished) switch between internal memory
files when connected to 24Vdc (-) supply.
11. The numbers shown refer to the scanner’s internal 8-pin and 9-pin
terminal blocks. The 59-546 and 59-547 quick-disconnect pins are not
numbered. The 95DSS3-WINC quick-disconnect pins are lettered
12. The following peripherals must be SELV/PELV by an approval
according to DIN EN 60950 or an external isolator must be used to
provide an SELV system:
- 24V power supply
- RS485
- 4-20mA wiring
- Remote file select monitoring
- Relay contacts
13. Cable quick-disconnect pins E and F (Red and Green wires) are
not connected to the 95DSS3-1WINC's internal terminal blocks.
Because the Fault Relay contacts are internally wired in series with
the Flame Relay contacts, the Fault Relay contacts are not available
for independent monitoring in the model 95DSS3-1WINC.
