DESCRIPTION
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 selec-
tion 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. Refer to Bulletins
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 soft-
ware, 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.
Note:
Proper operation of the YZ300 (YZ320) requires a BurnerLogix YB110 (YB230) with an
Engineering code of 3 or later or any ZB110 (ZB230) chassis/amplifier (Engineering codes
are found after the date code, e.g. 0636-03).
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 connec-
tion.
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. For a detailed description of the BurnerLogix System,
see Bulletins BL-1001 or BLZ-1001.
