Brief Description
The ETAMATIC regulates up to 4 control elements as a function of a control variable, in ac-
cordance with freely programmable curves. The ETAMATIC has 4 three-point step control out-
puts. The ETAMATIC S has 3 three-point step control outputs and one 4-20 mA output.
Examples of possible control elements:
•
combustion air damper
•
combustion air fan (ETAMATIC S only)
•
fuel valve
•
recirculation damper
Up to 20 points (usual 11) can be programmed per channel. The Display is relative between
0 and 999.
The ETAMATIC has a 25-pole Sub-D connector with serial interface for remote operation / re-
mote display via a PC (Windows software available separately). Connections for Interbus-S,
PROFIBUS-DP, CANopen, TCP/IP (Modbus TCP) and Modbus are available as optional
equipment. Other BUS-systems available on enquiry. The connection of other plant compo-
nents, e.g. fault signal systems and O
2
trim, is via the LAMTEC SYSTEM BUS interface to a
9-pole Sub-D connector.
Operation is via a front panel laminated keyboard. The parameters are displayed on a 2-row
LCD screen.
The ETAMATIC is also available as a special version without a front panel. In this case, oper-
ation is via optional PC software or programming unit. As display for end-user, a customers
interface is connectable via LAMTEC SYSTEM BUS.
The ETAMATIC continuously monitors its own functions and those of the connected control
elements.
230-V outputs:
•
Actuation of the gas valves
•
Actuation of the oil valves
•
Actuation of the oil pump
•
Actuation of the ignition valve and the ignition transformer
•
Fan release
•
Fault message
•
Open/Close control signals for the valve/damper motors
External signals to the ETAMATIC are transmitted via floating contacts or chains of contacts.
The following signals can be pre-set:
•
3 separate safety interlock circuits
•
fault release
•
air pressure monitor
•
control release
•
min. gas pressure monitor (for leakage test)
•
flame signal
•
ignition position acknowledgement
•
re-circulation on
•
burner on
•
select fuel
•
set-point switching (for load regulator)
