PROGRAM FUNCTION OF E1-CON AND E2-CON (Cont’d)
“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 in the input display to the totalizer value, every
time this operation is performed. The time-base, scale factor and
low cut-out in
“Module #5”
are in affect disabled, when this
function is selected.
“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 an
increase to the input signal while the remote input is low, the
display will reflect
(show)
the increase 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 in this function, the
other E-CON pin is operational.
“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 may occur.
“E2-CON” < > E2-CON has the same programmable functions as E1-CON.
