SGU 930 – Control Box

Control Box

The SGU 930 and SGU 930i control boxes are suitable for oil, gas and dual-fuel burners of high firing rates. Methods of flame detection include:

– Flame ionisation rod

– UV detector cell

– Infra-red flicker detector

The SGU 930 and SGU 930i control boxes have been designed to controland supervise single, two-stage and modulating burners on oil, gas or dual-fuel applications. Both are completely new designs. They combine the most up to date mechanics for the safety features together with electronic components. With the same dimensions as the earlier TM series of burner controls, the SGU 930 and SGU 930i contain the following design features and functions:

– 24 unit mechanical cam switch assembly and 4 relays for fail save functions

– Flame signal LED display

– Wiring base with 44 screw type terminals

– Programmable functions, with underside wiring links in the base

– 2-wire control for 3 position air damper motor

– Extendible safety interlock circuit and remote lockout option

– Replaceable internal fuse

– Separate start circuit for proof of closure switches
