Instructions For 123514A and 203659 Flame Simulators
Application
Flame simulators are devices that simulate a flame by reproducing ultraviolet resistance or rectification characteristics of an actual flame. Flame simulators simplify the troubleshooting of flame safeguard controls by providing a quick method to check the flame detection function. A simulator is typically used to simplifytroubleshooting when: 1. The pilot lights but the flame relay does not pull in, or 2. Shutdown occurs during the run period. Using a flame simulator provides a quick, positive indication of the source of trouble in the flame detection circuitry. If the flame signal is unsteady or weak, a flame simulator enables the service technician to determine whether the trouble is in the flame detector, externalcircuitry, plug-in amplifier, or flame safeguard control itself.

203659

Features
• Provides a quick, positive indication of the source of trouble in the flame detection circuitry. • Simulates flame by providing the ultraviolet resistance or rectification characteristics of the flame itself. • Designed to plug directly into the flame signal meter jack, test jack or into direct contacton Honeywell flame safeguard controls or plug-in amplifiers.

terminals on Honeywell flame safeguard controls or on plugin flame signal amplifiers.

CAUTION
Remove the flame detector leadwire to terminal F (or F1) on the terminal strip or subbase while using a flame simulator. In some cases (as shown in Fig. 5), a wire may have to be connected to the terminal strip or subbase to provideaccess to terminal F (or F1). Tables 1 and 2 and Figs. 1-23 show how the flame simulator is applied. If the flame simulator is applied properly, but the flame relay in the flame safeguard control does not pull in, the plug-in amplifier or the control itself is faulty. If the flame relay does pull in, the trouble is in the flame

NOTE: Flame simulators are not needed for self-checking flame detection systems. NOTES ON USING THE FLAME SIMULATOR 1. Only momentarily hold the simulator in position on the control. Whether the flame relay pulls in or not, removethe simulator as soon as the check is made. 2. If the control or amplifier has a meter jack (or test jack) in the F circuit, use the simulator to quickly check for a flame simulating condition that is preventing a start. Proceed as follows: a. If the flame relay is being held in and the burner cannot start, insert the simulator lead or plug into the meter jack. Hold the simulator probe end away...
