YZ300 FIREYE INTERLOCK ANNUNCIATOR, PROVIDES FIRST OUT ANNUNCIATION. 24V

YZ300 FIREYE INTERLOCK ANNUNCIATOR, PROVIDES FIRST OUT ANNUNCIATION 120V INTERLOCK ANNUNCIATOR, PROVIDES FIRST OUT ANNUNCIATION. 120 V - 120 V - 50/60Hz The FIREYE YZ300 (YZ320) Interlock Annunciator Module provides increased interlock supervision capability of the BurnerLogix System. The Interlock Annunciator Module connects to any YB110 (YB230) or ZB110 (ZB230) BurnerLogix chassis/amplifier by means of a cable, ( P/N ED580-2, ED580-4, ED580-8). By wiring any of twenty interlock switches into the Interlock Annunciator Module, the BurnerLogix display automatically acts as a “first-out” annunciator for these interlocks. In addition, a fuel selection circuit providing full annunciation even if two fuels are fired simultaneously is standard. The YZ300 (YZ320) is shipped with default messages associated with each set of terminals. The user has the ability to modify these lockout messages in one of two ways: 1. Use the BLV512 or BLL510 display module to select a lockout alarm message for the individual terminals of the YZ300 (YZ320) from a library of available messages. BL-1001 and/or BLZ-1001 for information regarding the operation of these controls. 2. Program a customized message (up to 40 characters in length) for the individual terminals of the YZ300 (YZ320) using a compatible PC with the Windows based YZ300P Programming software, available from Fireye and the appropriate hardware. Note: The YZ300 (YZ320) Interlock Annunciator does not need to be connected to a BurnerLogix system to be custom programmed. The Interlock Annunciator Module does not interfere with the normal operation of the BurnerLogix System. It expands the message and diagnostic capability. The wiring bases for the YZ300 (YZ320) measure 4 in. wide by 7 in. tall, consuming a minimum amount of cabinet space. The wiring bases contain a 24-position terminal block, each position clearly numbered and each terminal utilizing a clamping mechanism to assure a good mechanical connection. The YZ300 (YZ320) Interlock Annunciator module provides operational information and reduces troubleshooting time and expense. It expands the standard display messages of the BurnerLogix to identify the specific limit in the operating control circuit (L1-3) or running interlock circuit (3-P) which caused the burner shutdown or lockout.
