3 Description
External messages to the ETAMATIC V are supplied via potential free contacts or contact
chains.
The following signals can be predefined:
– Burner on
– Pre-purge
– Flame signal (burner operating)
– Control enable
– Recirculation on
– Curve set selection
– Setpoint switchover (for firing rate controller)
230 V-outputs for the communication with the external control device (isolated contacts via re
-
lay module type 660R0027):
– error main processor
– error monitoring processor
– ignition position main processor
– ignition position monitoring processor
– indication: high firing rate
The integral firing-rate controller is built as a PID-controller with special functions for combus
-
tion engineering. You may use it as a set-value controller or controlled by atmospheric condi
-
tions.
The following signals may be provided:
– actual value (analogue) - (PT100 or 4 - 20 mA)
– outside temperature or another analogue signal for setpoint switching (only with controller
controlled by atmospheric conditions) - (PT100, potentiometer, 0/4...20 mA)
– setpoint switching (via floating contact)
The release of the combustion with the firing-rate controller is carried out by an output at the
ETAMATIC V. A digital signal is the output for activating a relay for the connection with a burn
-
er sequencer (floating contacts via relay module type 660R0027).
