AGM60.4A9

The LMV36 burner management system is a microprocessor-based burner

control with matching system components for control and supervision of forced

draft burners of medium to high capacity.

For the use of dual fuel application with 2 fuel actuators, the AGM60 dual fuel

switch unit is required.

The LMV36 / AGM60 and this Data Sheet are intended for use by OEMs which

integrate the actuators in their products!

Use

Microprocessor-controlled LMV36 for single-fuel burners of any capacity, with electronic

fuel-air ratio control, with up to 2 actuators, and with integrated gas valve proving.

The system components (AZL2 and actuators) are connected directly to the LMV36 in

single-fuel operation. All safety-related digital inputs and outputs of the LMV36 are

supervised by a contact feedback network.

The AGM60 dual fuel switch unit connected to the LMV36 is used for switching the fuel

valve control and the feedback signals of both fuel actuators.

Type-tested and approved in accordance with DIN EN 298

Applications in accordance with EN 676: Automatic forced draft burners for

gaseous fuels

Applications in accordance with EN 267: Forced draft burners for liquid fuels

For intermittent operation in connection with the LMV36/AGM60, the ionization probe or

the QRA/QRC optical flame detector can be used.

Continuous operation is possible only when using an ionization probe and

without AGM60.

Features

The following components are integrated in the LMV36:

Burner control complete with valve proving system

Electronic fuel / air ratio control system for a maximum of 2 actuators SQM3 or

SQN1

Control of VSD for air fan

Modbus interface

BCI for connection a display or PC

Unit parameter adjustable either via display or PC software ACS410

Life cycle

The burner management system has a designed lifetime* of 250,000 burner startup

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 field).

The AGM60 dual fuel switch unit has a designed lifetime* of 5,000 burner startup 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 field).

This lifetime is based on the endurance tests specified in standard DIN EN 298. A

summary of the conditions has been published by the European Control

Manufacturers Association (Afecor) (www.afecor.org).

The designed lifetime is based on use of the LMV36 / AGM60 according to the

manufacturer’s Data Sheet and Basic Documentation. When reaching the designed

lifetime in terms of the number of burner startup cycles or time of usage, the LMV36 /

AGM60 must be replaced by authorized personnel.

* The designed lifetime is not the warranty time specified in the Terms of Delivery
