ALARM HISTORY
The sub-menu LOCKOUT HISTORY will display the last six (6) lockouts, along with the burner
cycle and burner hour when the lockout occurred. When the
MODE
key is pressed, the screen will
display the most recent lockout condition and the number of that lockout (e.g. LO #127 represents
the 127th lockout of that control). The
SCRL
key will display the Burner Hour, followed by the
Burner Cycle when the lockout occurred. The
SCRL
key will advance to the next lockout, and
repeat the sequence listed above. The
MODE
key will exit the sub-menu.
E320 MESSAGE SELECT
The sub-menu “E320 MSG SELECT” will allow the user to modify the lockout alarm messages
associated with the operation of the E320 Expansion Module. The various safety limits had to be
wired in the exact order that was shown in the E3201 Product Bulletin for the E320. For example, the
low water cutoff had to be wired between terminals 31 and 32 of the 60-1950 wiring base of the
E320. With the EP style programmers (Engineering code 21 or later), the user will now be able to
select which message applies to the individual terminals. The messages associated with the E320 are
divided into three (3) groups: Oil Select, Gas Select and Non-recycle.
The
Oil Select
group pertains to the terminals associated with the oil interlocks of the E320. These
are terminals 22, 24, 26, and 28.
The
Gas Select
group pertains to the terminals associated with the gas interlocks of the E320. These
are terminals 23, 25, and 27.
The
Non-Recycle
group pertains to the remaining limits connected between terminals 3 and P of the
E210/E211 control. These are terminals 29, 30, 31, 32, 33, 34, and 35.
The lockout messages associated with the above terminals can be modified via the ED510 Display.
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 as indicated in the E-3201 bulletin. For example, the
default message for terminal 29 is “COMBUSTION AIR FLOW FAILURE.”
TO MODIFY THE E320 MESSAGES
All three keys: Mode, Reset and Scroll, are used to modify the E320 messages. The Mode key is
used to enter or exit the sub-menu associated with the E320 messages. The Scroll key is used to
advance through the various terminals or selectable messages. The Reset key is used to modify a ter-
minal message and select a new message. To modify the E320 messages:
Press the Scroll key until the ED510 displays:
