3.1 Life Cycle
ETAMATIC V has a designed lifetime of 250,000 burner start-up cycles, which, under normal
operating conditions in heating mode, correspond to approx.
10 years of usage (starting from the production date given on the type plate).
This lifetime is based on the endurance tests specified in standard EN230/EN298 and the
table containing the relevant test documentation as published by the European Association of
Component Manufacturers (Afecor) (www.afecor.org).
The designed lifetime is based on use of BT300 according to the manufacturer’s basic docu
-
mentation.After reaching designed lifetime in terms of number of burner start-up cycles, or the
respective time of usage, the BT300 must be replaced by authorized personnel.
3.2 Brief Description
The ETAMATIC V positions up to 4 actuators, according to freely programmable curves, in de
-
pendence on a reference input variable. The "V" version has 4 three-step positioning outputs
and the "VS" variant has 3 three-step positioning outputs and a 4 - 20 mA output.
Examples of possible actuators:
• Combustion air valve
• Combustion air blower (ETAMATIC VS only)
• Fuel air valve
• Recirculation valve
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.
Operation via PC software is described in a separate manual.
The ETAMATIC V continuously monitors its own functions and those of the connected control
elements.
Unlike the ETAMATIC, the "V" version does not have a control unit, so the functions of the dig
-
ital inputs and outputs differ from those described in the ETAMATIC basic documentation.This
means that the "gas-tightness check" and "integral flame monitor" options available with the
ETAMATIC cannot be used with the "V" version.
