RM/EC 7800 Burner Controller Safety Manual
2 Using the Honeywell 7800 Series
Relay Modules
2.1 Safety Function
The 7800 Series provides automatic burner flame sequencing
and flame supervision with protection against loss of flame.
2.2 Fail Safe State
The Safety Shutdown (Lockout) mode is the failsafe state for
the Honey well 780 0 Series Relay Modules where all safety
critical terminals (main and pilot valves, and ignition transformer) are de-energized and a manual reset is required to
return to normal operation.
2.3 Safety Response Time
The Honeywell 780 0 Series Relay Modules (all models except of EC7823 and RM7823) will respond to loss of flame
by means of shutting of f all safety outputs and transitioning
to the Safety Shutdown (Lockout) state within the published
Flame Failure Response Time (FFRT) for the selected Flame
Amplifier and Flame Sensor.
EC7823 and RM7823 will respond to loss of flame by means
of shutting off the safet y outputs and transitioning to the
Idle state within the published Flame Failure Response Time
(FFRT) for the selected Flame Amplifier and Flame Sensor.
Safety Shutdown (Lockout) state is not entered and manual
reset action is not needed in this case.
2.6 Model Selection and Specification of
Honeywell 7800 Series Relay Modules
The Honeywell 780 0 Series Relay Modules and optional components for certified SIL applications shall only be selected
and specified for applications consistent with the guidelines
presented in the Installation Instructions document and additional technical literature released for the specific model
available at web site https: //customer.honeywell.com and
further restricted to the certified Flame Amplifiers and Flame
Detectors identified in section 1 of this Safety Manual.
2.4 Diagnostic Response Time
The Honeywell 780 0 Series Relay Modules will report a detectable internal failure within 3 seconds for faults to the main
7800 Relay Module and within 15 seconds for faults to the
Flame Detector / Flame Amplifier.
2.5 Maximum Achievable SIL
The 7800 Relay Modules, Flame Amplifiers and Flame De-
tectors covered by this safety manual are suitable for use in
both high and low demand mode of operation Safety Integrity
Functions (SIF) up to SIL 3 in simplex (1oo1) configurations.
The achieved SIL for a particular SIF needs to be verified by
PFH or PFDavg calculation for the entire SIF including the
failure rates of the associated sensors and actuators that are
also part of the SIF.
Use of the Honeywell 7800 Series Relay Modules in a redundant (1ooN) configurations is not supported.
The 7800 Series Burner Controller System is classified as a
1
Type B
fault tolerance of 0.
1 Type B element: “Complex” element (using micro controllers or
element according to IEC 61508, having a hardware
programmable logic); for details see 7.4.4.1. 3 of IEC 61508-2, ed,
2010
