Product Overview

DESCRIPTION

The Fireye MEP300, MEP304, MEP335 and MEP397 Programmer Modules are used with the Fireye

Modular MicroM control. The MEP300 series programmers provide additional enhancements such as

early spark termination, pilot proving and interrupted or intermittent pilot operation. These programmers

must be used with the MEC320 and MEC480 series chassis. The programmer module incorporates a plug-

in design for easy installation.

The advantages of the Micro M are zero dependence on discrete components previously used for timing

functions. The MicroM, through the use of micro-controller technology, incorporates smart diagnostic

LED’s, smart reset function for multi-burner applications, optional alpha-numeric display output (ED510)

and serial communications via a Modbus Interface. A “check-run” switch is provided on the MEP397 pro-

grammer module to assist in testing size and stabilization of the pilot.

Flame Failure Response Time (FFRT) is determined by the selection of the amplifier module. Test jacks

are also provided on the flame amplifier module to permit flame signal measurement during operation.

For proper and safe application of this product, you must refer to Fireye bulletin MC-5000 for a detailed

description of the various programmer modules, including installation instructions, amplifier selection,

operating sequences for each programmer module, etc.

WARNING: Selection of this control for a particular application should be made by a competent

professional, licensed by a state or other government agency. Inappropriate application of this

product could result in an unsafe condition hazardous to life and property. Installation should not

be considered complete until pilot turndown and other appropriate performance tests have been

successfully completed.

 WARNING: Remove power from the control before proceeding. INSTALLATION The Programmer Modules are used with the Fireye modular MicroM Chassis (P/N MEC320, MEC320RC, MEC320R, MEC320D and MEC320C for 120VAC and MEC480 for 230 VAC). They are installed in the chassis by grabbing hold of the programmer module by the ridged finger grips on the side on the module, aligning the module with the guide slots on the opening farthest from the transformer, and inserting the module into the pin connectors.
