6.1 Output of On/Off signals or collective error messages (relay table)
As can be seen from the above table, relay outputs R1, R2 and R4 are switched depending on
the operating state or error status of the appliance. This feature can be used to forward
messages from the wodtke appliance to an external controller or a modem, permitting remote
sampling of functional values, for example. In this case operating states and collective errors
are defined as follows.
Note:
•
15-minute fan after-run “G OFF” counts as operating time.
•
Relays R1 and R2 are designed as make-contact (not break-contact) relays (i.e. closed
when operated).
•
Relay R4 is designed as a break-contact relay (potential-free, 2 A maximum load).
R1 = On/Off signa:
R1 = 0 V
= stove off message “R1 OFF”
R1 = 230 V = in operation message “R1 ON”
R2 = collective error message
R2 = 0 V
= error message “R2 OFF”
R2 = 230 V = no error message “R2 ON”
R4 = potential-free On/Off signal (monitored break-contact safety relay):
R4 = closed
= stove off message “R4 OFF”
R4 = open = in operation message “R4 ON”

Either ON or OFF
An error has occurred

NO YES NO YES
Either YES or NO,
since not ready for

Note:
I/O key on the operating panel overrides all other controls = “heater emergency switch”
for the pellet stove.
