Set-up Manual

DESCRIPTION

The E340 Boiler Room Control is a microprocessor-based Boiler Management System designed to interface with and expand on the capabilities of the existing FIREYE® FLAME-MONITOR™ and "D" Series Flame safeguard control systems, as well as competitive flame safeguard systems. Fol­lowing are some of the monitor and control capabilities provided by the E340:

• Operating Control Function for automatic sequencing of the boiler system to start and stop the boiler to meet system demand.

• Full Modulation Control of fuel and combustion air through the firing rate motor to meet sys­tem demand.

• Solid State Sensors to monitor steam pressure, water temperature, oil pressure, gas pressure, oil temperature, stack temperature, boiler water temperature, or outdoor air temperature.

• High and Low Pressure and Temperature Alarm Limits (user selectable) based on inputs from solid state sensors. Exceeded limits will open interlock circuit to the flame safeguard con­trol for shutdown of the burner and boiler.

• Cold Start Thermal Shock Protection to slowly increase the burner firing rate on a cold start to limit mechanical stress due to thermal differences.

• Interface with an Existing Flame Safeguard Control (Fireye FLAME-MONITOR, D-Series, or competitive flame safeguard control to provide ease of installation in a retrofit application.

• Lead/Lag operation of two boilers.

• Remote Communication Capability to access system information via IBM compatible PC and E340 Communications Software.

• Keypad/Display Module with 8 character LCD Display and 12 key keypad for on-site pro­gram and review of system setpoints and operating parameters.

• Software Password Protection (two levels of security) to restrict unauthorized entry and mod­ification of system setpoints and operating parameters.

• Time of Day scheduling to program set-back of water temperature or steam pressure setpoints.

• Timed Override of Setback Schedule via momentary push button. Override period keypad

selectable.

• Marginal High and Low Pressure and Temperature Alarm Limits (user selectable) based on input from solid state sensors to indicate system approaching high or low alarm limits.

• Auxiliary Analog Output (4-20 mA) to provide an output signal (to a chart recorder) that is directly proportional to one of the five pressure or temperature sensors.

• Programmable Maximum High Fire Position of modulating firing rate damper motor.
