Indicator N1500G
NOVUS AUTOMATION
4/6
Within a certain cycle just press
to go to the following
parameters. At the end of each cycle the display will go back to the
work cycle.
At the desired prompt just press the
or
key to
change this
parameter accordingly.
All changes are recorded in non-volatile memory as we move to next
prompt. After 25 seconds with no key pressed the indicator will return
to the measuring cycle (work cycle).
7.1.
CYCLE PROTECTION
The values of parameters of a certain cycle can be protected against
non-authorized users.
The protected parameters can still be viewed but can not be
changed.
To protect a cycle just press the
and
keys for 3 seconds at
the beginning of the referred cycle. To unlock this cycle (allow
changes in parameters), press the keys
and
for 3
seconds.
The display will briefly blink confirming that the locking or
unlocking of the cycle.

PROGRAMMING THE INDICATOR
8.1.
WORK CYCLE
This is the first and main cycle. At power up the indicator will display
the Process Variable (PV). The alarm setpoints are also displayed at
this cycle. To run through this cycle just press the
key.
Whenever an alarm is set with differential function the respective
alarm setpoint is blocked (
SP.AL1

SP.AL1
,
SP.AL2

, ...) and the display
shows “

” to advise the operator that this is a configuration
parameter and that the respective deviation value must be
programmed at the Alarms Cycle. The “
AL.rEF

” prompt will be
displayed showing the reference value for the alarm with differential
function.

Measure
Shows the measured variable. For Pt100
or thermocouples the display will show the absolute
temperature value.
For 4-20 mA, 0-50 mV and 0-5 V inputs the display
shows the values defined in the “
in.LoL
in.LoL
in.LoL
in.LoL
” and
“
in.HiL
in.HiL
in.HiL

” prompts.
With the
hold
function programmed the display
shows the frozen variable and alternates with the
message “
HoLd
HoLd
HoLd
HoLd
”.
Likewise, with
Peak
Hold
function programmed the
high limit is displayed with the “
P.HoLd

” prompt
alternately.
Should any fault situation occur the indicator will
display an error message which can be identified at
item 10 of this manual.

Input Digital Filter
- Adjustable from 0 to 20, this is
used to reduce instability of the measured value.
0 means the filter is off and 20 means maximum
filtering. The higher the filter value the lower is the
measured value response.

Display Offset
- This a value which is added to the
PV to offset any measurement deviation or sensor
error. The offset is shown directly in the programmed
engineering unit.
For °F measurements the null reference is at 32 °F.
