OPERATING THE IMY
After completing all set-up operations, the unit is ready to install and
operate. After power is applied, a display test consisting of illuminating all
segments for 2 seconds is performed. Afterward, the input or total will
appear, depending upon the display mode prior to the last power-down. To
switch the display to input, press “DOWN” (indicated by “arrows” on the
front panel) and to switch it to total, press “UP”. If the integrator/totalizer
option is not installed, then display switching to total is inoperative. A minus
sign “-” will precede numbers that are negative.
QUICK PROGRAMMING
To limit access to the set-up parameters, connect a key-switch or wire from
PGM. DIS. (TBA #3) to COMM. (TBA #7). With this pin connected to
common, only a predetermined amount of data can be viewed or altered, as
programmed by programming module #3. If “NO” was programmed for all of
the available steps in module #3, then pressing “P” will cause the unit to
display “Loc”. However, if “YES” was programmed in one or more of the
steps, then “P” will invoke entry into a series of commonly modified
parameters while protecting the crucial set-up information. This is referred to
as the “quick programming” mode. When “quick programming” mode is
entered, the alarms and hysteresis values can be modified in the same manner
as in the regular programming mode. The new alarm and hysteresis values
will take effect when “P” is pressed.
The other operations in the “quick programming” mode require special
key sequences as shown:
To reset latched alarm, scroll through steps in “quick
programming” mode using the “P” button until “LAtCH1” or
“LAtCH2” appears in the display. If they do not appear, they are
not latched.
To reset: While “LAtCH1” or “LAtCH2” is being
displayed, press and hold “DOWN” and press “P”.
Pressing “P” alone causes a step to the next item
with no action on the alarm.
To reset peak and valley buffers, scroll through steps in “quick
programming” mode using the “P” button until “PEA” or
“VAL” appears in the display.
To reset: While “PEA” or “VAL” is being
displayed, press and hold “DOWN” and press “P”.
Pressing “P” alone causes a step to the next item
with no action taken on the buffer.
The front panel buttons are not only used to input data during the
programming and “quick programming” mode, but control a number of other
functions (if enabled in Pro “3”) as well. In the normal meter mode, these
functions are available:
To switch to display of input: Press “DOWN” button.
To switch to display of totalizer: Press “UP” button.
To reset totalizer to zero: Press and hold “UP” and press “P”.
To enter programming or “quick programming”: Press “P”.
After each operation, a message will appear briefly to acknowledge the action.
