Technical Data
Signal outputs
Monitor output: 4 … 20 mA signal, apparent ohmic resistance > 600 S
Correction inputs: 2, adjustable to 0 … 20 or 4 …20 mA
channel and effect adjustable via parameters
Digital outputs via
relay module R 16 (Contact material AgCdO, designed for 230 V AC switching voltage)
___________________________________________________________________
NOTE:
Only passive or non-reactive units may be connected to the outputs of
the R 0016 relay module. Any infeed of 230 V into the unit via terminals
82 - 92 in the event of a fault must be prevented.
___________________________________________________________________
230 V supply All consumers connected to the R 16 relay module are supplied via this
terminal 81 terminal.
It is to have fuse protection provided by the customer in the form of a
max. 16A delayed action fuse.
Main gas 1 Contact for actuation of the gas line-side main gas valve
terminal 82 max. 2A, cos max. 0.4
Main gas 2 Contact for actuation of the burner-side main gas valve
terminal 83 max. 2A, cos max. 0.4
Oil Contact for actuation of the two oil valves
terminal 84 max. 2A, cos max. 0.4
Ignition valves Contact for actuation of the ignition valve(s)
terminal 85 max. 2A, cos max. 0.4
Ignition transformer Contact for actuation of the ignition transformer
terminal 86 max. 2A, cos max. 0.2
Fan (burner start) Contact for actuation of the fan motor and all other components
terminal 89 that have to be activated at the start
max. 2A, cos max. 0.8-1 (together with pre-ventilation signal)
Gas operation signal Contact for signalling of the fuel selection. Not active in the off-state
terminal 90 max. 0.5A, cos max. 0.8-1
Oil operation signal Contact for signalling of the fuel selection. Always active in the off-state
terminal 88 max. 0.5A, cos max. 0.8-1
Heated oil distribution Contact for actuation of oil pre-heating. Active in oil operation from the
terminal 87 burner start to the main valve release
max. 2A, cos max. 0.8-1
External pilot gas line Contact for actuation of the shut-off valve of a more remote
terminal 91 pilot gas supply. Active from end of pre-ventilation to main valve release
max. 2A, cos max. 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 Contact for signalling of the pre-ventilation or post-ventilation mode
terminal 92 max. 0.5 A, cos max. 0.8-1 (together with fan)
