B. ALARM OUT (terminal 5), SHUTDOWN OUT (terminal 6), FIRE CONFIRM OUT
(terminal 7): Three output switches are available for monitoring ignition system
status. Each output consists of a solid state switch normally closed to a single
common rail COMMON OUT (terminal 8). The switches are rated
75mA @ 100Vdc. These output switches are electrically isolated from all other
terminals. The recommended hook-up is shown in Figure 11.
C. 4-20mA TIMING CONTROL INPUT: The 4-20mA timing control loop connects
to terminals 9(+) and 10(–). This input is electrically isolated from all other
terminals; refer to Figures 11 and 15.
D. MISC INPUT (terminal 11): Provides for control of various user-selected
features. This input is normally open; connect to engine ground to activate the
selected feature (see Figure 11). NOTE: This is a 5-volt low-level signal.
E: 4-20mA SPARK NUMBER CONTROL INPUT: The 4-20mA spark number
control loop connects to terminals 3(-) and 4(+) of the 2nd (rear) terminal strip.
This input is electrically isolated from all other terminals.
F: SPARK NUMBER OVERRIDE (rear terminal 1): Provides a user-configurable
override of the current selected spark profile number. This input is normally
open; connect to engine ground to activate the selected feature. NOTE: This is
a 5-volt low-level signal.
G: RS-485: The terminals: 5(GND), 6(–), and 7(+) provide an RS-485 port for
external control VIA PC or PLC.
