The Honeywell Semi Automatic Programming Control is a versatile, industrious instrument designed for efficient flame supervision and system control. Operating on 120 VAC and 50/60 Hz., this controller relies on an interrupted pilot type and includes lockout interlocks for elevated safety measures. It comes fitted with a programmable VPS check feature and a highly visible blinking LED fault indication system.

Significant functions of this Honeywell product include system purge, burner pilot startup, flame supervision, system status indication, as well as system and self-diagnostic troubleshooting. The controller maintains a 10-second or intermittent main flame establishing period, along with a 4-second or 10-second pilot flame establishing period.

Built with a valve proving feature and programmable post purge time, this system ensures effective and safe operations. In case of a system lockout, the power LED provides identifiable fault codes by blinking. The system prioritizes safety, delaying the admission of fuel into the combustion chamber until the pilot flame is established and ensuring constant flame monitoring throughout the run period.

The Semi Automatic Programming Control package includes an S7800A1142 Keyboard Display Module, boasting five LEDs for precise sequence information. It also offers flexibility through its interchangeable plug-in flame amplifier, and external access for electrical voltage checks. The controller's non-volatile memory-upholds system history files and lockout status even after a power loss.

This unit is designed to offer application flexibility and optional communication interface capability, extending its usage across various industrial demands. It is fully compatible with existing Honeywell flame detectors ensuring seamless integration within existing setups. The controller is designed to work efficiently under operating conditions ranging from -40 F to 140 F, and incorporates an early spark termination feature that activates within 5 seconds. Overall, the Semi Automatic Programming Control is a reliable choice for maintaining operational efficiency and safety in combustive industrial systems.
