Chapter 1. OVERVIEW AND PRODUCT
CONFIGURATION
n Overview
The FRS100 Multiburner Control features built-in safe-start circuitry. To ensure
safety, this circuitry prevents ignition if a failure is detected at startup, and shuts
off the fuel line if the flame is interrupted during operation. Combined use with an
ultraviolet flame detector or flame rod enables batch operation of burners.
n Features
• The start check function inspects the flame detector and flame relay body at
startup to ensure safe operation. If an abnormality is found, ignition is
prevented.
• The controller is designed to be compact, and can be plugged into the wiring
sub-base. The sub-base can be mounted by screws or onto a DIN rail.
• The power supply state and ignition detection can be read easily from the LEDs
on the front display. Completion of the start check is indicated by the LED on
the center of the body behind the front cover.
• Flame voltage output (0 to 5Vdc) can be checked at the dedicated terminal by a
general-purpose tester, or continuously monitored by a panel meter or recorder.
• The controller has a dedicated connector so that the optional FRS60A Flame
Meter can be attached.
