ORDERING INFORMATION
OPERATION
The YZ300 (YZ320) Interlock Annunciator Module is designed to expand the capability of the
BurnerLogix System by allowing the operator to individually track the operation of four (4) recy-
cling interlocks and sixteen (16) running interlocks (non-recycling). The recycling interlocks are
wired between the L1-3 terminals on the BurnerLogix wiring base and the non-recycling interlocks
are in the 3-P circuit.
Referring to the wiring diagram, Figure 2 on page 8, the operating control and auxiliary limits 1, 2
and 3 will act as an operating control to recycle the burner. Whenever any of the auxiliary limits are
open and the other limits are closed, the message on the display of the BurnerLogix control will indi-
cate:
STANDBY
L1-3 AUX #1(or #2, or #3) OPEN (or the appropriate modified message)
Similarly, the interlocks in the 3-P circuit will change the standard running interlock message on the
display from: LOCKOUT 3-P INTLK OPEN to one which will individually identify the sixteen (16)
interlocks now being monitored by the YZ300 (YZ320), such as, LOCKOUT LOW OIL TEM-
PERATURE (or the appropriate modified message). The interlock switch chosen will be selected on
