4 Operating Description

4 Operating Description

(for specimen diagrams, see Appendix 9.8 Process Sequence Charts)
A signal is first fed to terminal 58 (Burner On) indicating when the burner is to start. 

The ETAMATIC then interrogates the boiler safety interlock circuit or the common safety inter­lock chain (ETAMATIC) and the contact of the air pressure monitor. If it does not detect an
"OK" condition, the text of a corresponding message appears and the operating control stops.

If all signals are OK, the fan output is activated and the ducts run to their bottom stop as a
check.

Once all channels have reached their bottom stop, they open for aeration. The leakage test
runs in parallel (gas operation only).

In the case of control elements the aeration is used to enter and/or test the range limits. After
reaching its top position, the fuel control element runs back into the ignition position. All other
channels remain in open position. The ETAMATIC then interrogates the air pressure monitor.
If this signal is OK, the parameterised aeration time runs. If a channel is configured for re-cir­culation, it opens with a time-delay. On reaching the parameterised re-circulation delay time,
the aeration time stops. As soon as the re-circulation channel has reached the aeration posi­tion, the aeration time is resumed. When this time has expired all the channels run to the pro­grammed ignition position (re-circulation fully closed). After the lapse of the aeration time, all
channels run to the programmed ignition position (recirculation closed)

4.1 Starting without pilot burner

The main valves open and together with the ignition transformer remain activated for the du­ration of the safety time. During this time the flame signal appears.

4.2 Starting with pilot burner

The ignition valve and main gas 1 (in gas operation) or the ignition valve alone (in oil operation)
run open. The pilot flame forms and the flame detection detects the flame. The flame detection
sends the signal to the burner control device.

On expiry of the 1
time) the pilot burner burns alone. Then main gas 2 or the oil valve opens and remains acti­vated in parallel with the ignition valve for the duration of the 2
closes again at the end of this period.

3 seconds after ignition, all channels run to the programmed base load point. The ETAMATIC
remains in base load position until control release is given.

After control release the ETAMATIC follows the power control unit’s default setting.
A shut off follows the cancelling of the signal of the terminal 58. The main valves close. In gas

operation, first main gas 1 and second main gas 2 closes with a delay of approx. 5 sec., in
order to allow the test line between the solenoid valves to burn out. In the event of a fault shut­down, both close immediately.

If configured for post-ventilation, the air channels open again for this period.
Thereafter the ETAMATIC is in the "OFF" mode.

In this parameter you define the type of actuator the
respective output channel controls. This indirectly deter­mines the channel’s behaviour at pre-ventilation, at
band shifting, at changes of the burner-firing rate and at
drift compensation. This possibly may, affect special
functions (e.g. if the channel is configured to recircula­tion or flue gas).

Behaviour of the actuators with FMS:
steam = Remains CLOSE until the pre-ventilation time

has expired. After that the actuator runs to
ignition position.
REZI = Runs OPEN after the configured pre-ventila-
tion time, even if terminal 6 has a signal. In reg-

flue gas = Runs completely open in BE and remains
open until ignition. Then the actuator runs to
compound. At start without VO, ignition starts
not until flue gas is completely open.

has expired. After that the actuator runs to
ignition position.
REZI = runs open to the configured number of points
in VO = position, which the allocated air actua-
tor must have reached (terminal 6 has signal).

5.1.7 Recirculation Delay

Select parameter no. 427

No FMS ETA Short Text Description Min Max Default

427 1 1 VO Del R Number of points of air channel of recirc. (VMS)/delay

time (FMS)
Number of points of an air channel for recirculation

(VMS) / delay time (FMS) in seconds.
With VMS it is necessary to couple the recirculation flap

delay with an air channel during pre-ventilation. There­fore an air channel is assigned to the recirculation flap
(see P 428). The opening of this air channel now deter­mines the moment, when the recirculation flap shall
open. Set in this parameter the number of digits the air
channel has to reach, before recirculation becomes
active.

If the device is an ETAMATIC or a FMS, set the delay
time in seconds before the recirculation flap opens,
i. e. during this period only the boiler is ventilated.

The total pre-ventilation duration (P 785) has to be
greater than the value in this parameter.

- VMS opening of the air channel for delay of the 
recirculation channel (in digit)

0 = OFF
1 = constant burner sequencer
2 = control by atmospheric condition 1
3 = control by atmospheric condition 2

For ETAMATIC, P 809 selects from which input the
actual value signal should be taken. If the parameter is
set to 1, the integrated PT100 input is used, otherwise
the firing rate input.

If the ETAMATIC uses the PT100 input as the actual
value signal for the internal firing rate controller, you
may deactivate the firing rate controller with a bridge
between terminals 19 and 20. The firing rate input
occurs via terminals 3-6.

NOTICE!
These parameters (P 356 - P 359, P 366, P 367, P 427, P 774, P 775 P 785, P 790, P 833)

must be adjusted to the system before commissioning. Further parameters which, although
you can alter them, only need to deviate from the standard setting in exceptional cases, are
given below.

A counter generates the external firing rate with a TPS
signal. It counts up or down, depending on the contact.
This parameter sets the speed of the counter. Set the
parameter to 0, if the firing-rate input is not TPS.
With manual mode the load default via redundant feed­back channel 2 is treated as TPS load, if TPS load is
configured (P 718  0).

1000 = continuous ventilation (from 5.0 on)
Set the duration, how long the VMS/FMS/ETAMATIC

ventilates after a switch OFF. The air flaps were open
for this purpose. A fan output runs to 20mA. The FMS/
ETAMATIC holds the release signal of the fan.

No post ventilation occurs if the parameter content is 0
and in the case of a fault shutdown.

The actuators are not monitored in post ventilation
mode! The actuators only open when the flame is extin­guished. The time begins to run immediately with clos­ing of the magnetic valves. It may be necessary to add
this post burn time to the required post ventilation time
