petent professional, licensed by a state or other government. Inappropriate application of this
product could result in an unsafe condition hazardous to life and property.
DESCRIPTION
The Fireye MicroM Series Flame Safeguard Control is a compact, microprocessor based,
modular burner management system designed to provide automatic ignition and continuous
flame monitoring for commercial sizes of heating and process equipment firing any type of
fuel. The advantages of the MicroM are zero dependence on discrete components previ-
ously used for timing functions thereby extending the stability of the system and reducing
the effects of time and temperature.
A complete MicroM system consists of the relay module, MEC320TS, programmer mod-
ule, MEP696, amplifier module, MEUV4, subbase, 61-3060 or 61-5042 and UV scanner,
UV1A3 or UV1A6. An optional alphanumeric display (ED510) is available that provides
complete English language description of the current operating status as well as diagnostic
history.
To maximize safety the MEP696 provides early spark termination followed by a pilot prov-
ing period. This prevents the unwanted detection of spark generated by a maladjusted pilot
and spark assembly. The air flow switch connected between terminals 7 and 6 must be
closed within 10 seconds after the start of a cycle. Below is a detailed list of the MEP696
operating parameters.
Functions provided on the MEC320TS chassis and MEP696 programmer:
1.
Fixed 30 second pre-purge period
2.
Ignition terminal 4 shuts off 10 seconds into the Pilot Trial for Ignition
3.
5 second Pilot Proving period
4.
Pilot terminal 3 shuts off 5 seconds into the Main Trial for Ignition
5.
Post Purge has selectable 0 or 60 seconds duration
6.
Release to modulate contacts 1 second after AUTO
7.
Lockout occurs if air flow, terminal 6, is not proven 10 seconds into purge
8.
Modbus communications allowing for hookup to plc system
9.
Dip-switch selectable communication baud rate, 4800, 9600 or 19200 baud
10.
Dip-switch selectable pilot trial for ignition timing, 5 or 10 seconds
11.
Smart LEDs that provide on board diagnostic lockout information
12.
Amplifier test jacks provide uniform 0-10 vdc for flame signal strength
