“8” - If the alarm option is installed, a negative going edge
resets the latched alarm(s).
“9” - If the alarm option is installed, a low level resets a
latched or unlatched alarm into its inactive state. This
provides manual override of alarms for system startup
and other unusual events such as system testing.
“10” - A negative going edge toggles the display between
“input” and “total” (from input to total, or vice versa).
No action is taken on the positive going edge.
“11” - A negative going edge zeros (tares)
the input signal and
adds the value that was on the input display to the
totalizer value. The time-base, scale factor and low
signal cut-out in “Module #5” are in effect disabled,
when this function is selected. Example: 25.0 pounds of
one ingredient is loaded, input is tared to 0.0, totalizer =
25.0 pounds. 50.0 pounds of another ingredient are
loaded, input is tared to 0.0, totalizer = 75.0 pounds. This
acts as a batch totalization.
“12” - Display hold with tare. A negative going edge tares
(zeros) the input signal. Prior to the tare operation, the
input signal is saved and held (display hold) as long as
the remote input pin is low. On the positive edge the
input display will show zero. If there is a change to the
input signal while the remote input is low, the display
will reflect (show) the change at the positive edge.
“13” - Instrument reading synchronization. A low level
disables all meter operations (alarms, total, analog out,
etc.). A positive edge resets the start of the A/D
conversion, to allow synchronization with external
processes and controls. While this function is active, the
other E-CON pin will be acknowledged.
“14” - Print request. Transmits data according to the print options
that have been selected in Program Module #7. If the low
time exceeds 800 msec, a second print-out will occur.
“E2-CON” < > If the totalizer option is installed, E2-CON has the same
programmable functions as E1-CON.
