PROGRAM FUNCTION OF E1-CON AND OPTIONAL 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 start-up 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 offset. A negative going edge tares (zeros)

the input signal. Prior to the offset 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 will be

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”<>Ifthetotalizer option is installed, E2-CON has the

same programmable functions as E1-CON.
