MFA 2, status signal
(max. 2 A)
Possible parameterization options:
– Fault NO (default setting):
For example, the input for a horn can be set to
NO.
– Fault NC:
The input on an environmental control computer
can be set to NC (e.g. to indicate a cable dis-
continuity).

▷
Connector X9 is not wired at the factory. In other
words, the burner heats at its full capacity.
▷
A capacity range from 60 to 100% can be se-
lected using a voltage or current signal. A signal
sensor is connected to connector X9 for this
purpose:
0 mA/0 V = maximum capacity,
20 mA/10 V = minimum capacity.
Burner Chip Card (BCC)
▷
All the data relevant to the device are saved
on the BCC and the internal device memory
(EEProm). In addition, the parameters are saved
on the BCC.
CAUTION
Danger of electric shocks!
– Before working on possible live components,
ensure the unit is disconnected from the power
supply.
– If the BCC is removed from the burner control
unit, the heater RGA 100 will be non-functional.
▷
In the event of faults which cannot be rectified
by authorized trained personnel, contact the
supplier.
▷
The BCC can be removed from the burner control
unit and submitted for diagnostic purposes by
agreement with the supplier.

Delay
▷
If no other fault is active, the RGA 100 can be
readied for use again by inserting a new BCC.
The BCC must be compatible with the RGA 100
and the gas type used.
Setting the switch-on delay
▷
If multiple heaters switch on at the same time,
there can be a gas and/or power shortage on
individual devices. To avoid this happening, ad-
just the switch-on delay using the potentiometer
on the burner control unit.
▷
The potentiometer is set to 0 s at the factory.
– +
▷
If necessary, a switch-on delay of 5 to 10 s can
be set between the devices.
6
After completing the wiring, close the cover
and the housing cover on the burner control
unit again.
7
Switch on the power supply.
▷
A circulating dash will be displayed when the
voltage supply is switched on to indicate that
the switch-on delay is running.
8
Release the gas supply.

Commission the heater.
