YZ300 (YZ320) MESSAGE SELECT
The sub-menu "YZEM MSG SELECT" will allow the user to modify the recycle and non-recycle
messages associated with the operation of the YZ300 (YZ320) Interlock Annunciator Module and
BurnerLogix. The use of the default messages requires the system to be wired as shown in the wiring
diagram. For example, the low water cutoff had to be wired between terminals 43 and 44 of the
YZ300 (YZ320). The YZEM MSG SELECT option now allows the user to select from a library of
messages and program each interlock terminal as required. The messages associated with the YZ300
(YZ320) are divided into four (4) groups:
Recycle, Non-recycle, Gas Select, and Oil Select.
The
Recycl
e group pertains to the limits that are connected between terminals L1 and 3 of the Burn-
erLogix. These are terminals L1-40, 40-41, 41-42, and 42-3.
The
Non-Recycle
group pertains to the limits that are connected between terminals 3 and P of the
BurnerLogix. These are terminals 3-43, 43-44, 54-55, 55-56, 56-57, 57-58, 58-59, 59-60 and 60-P.
The
Gas Select
group pertains to the terminals associated with the gas interlocks of the YZ300
(YZ320). These are terminals 50-51, 51-52, and 52-53.
The
Oil Select
group pertains to the terminals associated with the oil interlocks of the YZ300
(YZ320). These are terminals 45-46, 46-47, 47-48, and 48-49.
The lockout messages associated with the above terminals can be modified via either the BLL510 or
BLV512 displays.
The selection of available messages are dependent on each group. For example, the message "Low
Oil Pressure" is a selection only for the Oil Select group. The default message for a particular inter-
lock is the standard message for those terminals. For example, the default message for terminals 40-
41 is "L1-3 AUX #1 OPEN."
