Analyzer electronics assembly
Figure 1–8 shows the analyzer electronics assembly. The analyzer power
supply provides power to the analyzer control electronics. The analyzer control
electronics drive the laser, collect the signal and analyze the spectra. A DIN rail
holds fused terminal blocks, the temperature controller and solid-state relay for
the heater, powered relays controlling the solenoid valves and un-powered
relays serving as alarm contacts.
See Figure 1–5 and Figure 1–8 for locating fuses. If you need to
replace a fuse, use only the same type and rating of fuse as the
original as listed in Table 1–1. Refer to Table A–2 on page A–2 for
replacement fuse part numbers.
