4 Appendix
Fan (burner start)
terminal 89
Contact for actuation of the fan motor and all other components that have to be activated at
the start.
max. 2 A, cos φ ≥ 0,8-1 (together with pre-ventilation signal)
Gas operation signal
terminal 90
Contact for signalling of the fuel selection. Not active in the off-state
max. 0,5 A, cos φ ≥ 0,8-1
Oil operation signal
terminal. 88 Contact for signalling of the fuel selection. Always active in the off-state
max. 0,5 A, cos φ ≥ 0,8-1
Heated oil distribution
terminal 87 Contact for actuation of oil pre-heating. Active in oil operation from the burner start to the
main valve release
max. 2 A, cos φ ≥ 0,8-1
External pilot gas line
terminal 91 Contact for actuation of the shut-off valve of a more remote pilot gas supply. Active from
end of pre-ventilation to main valve release
max. 2 A, cos φ ≥ 0,4
If the contact is not needed for this purpose, the terminal must remain free (e.g. in systems
without pilot burner)
Pre-ventilation / Post-
ventilation
terminal 92
Contact for signalling of the pre-ventilation or post-ventilation mode
max. 0,5 A, cos φ ≥ 0,8-1 (together with fan)
Fault terminal 93 Contact for signalling of a fault condition. Signalling follows only after closing of the main
valves (normally open contact, floating)
max. 0,5 A, cos φ = 0,8-1
Fault terminal 95 Contact for signalling of a fault condition. Signalling follows only after closing of the main
valves (normally closed contact, floating)
max. 0,5 A, cos φ = 0,8-1
Fault terminal 94 Supply input for fault contact 24 V DC or 230 V AC
Times: Pre-ventilation time adjustable from 1 up to 999 sec.
1. safety time oil 4 sec.*
1. safety time gas 4 sec.*
2. safety time oil 4 sec.* (when starting without pilot burner = safety period)
2. safety time gas 3 sec.* (when starting without pilot burner = safety period)
The times may differ depending on the application.
(shorter times also available for special plant)
* This period is exclusive of the external flame monitor's reaction time.
I.e. the system's total safety period is equal to that given above + flame monitor's reaction
time (usually 1 sec)
Storage of set-point
values and variable
data In EEPROM up to 20 points per curve with linear interpolation
