5.4 F3 - Limits - High/Low
Menu F3 indicates if high and low limit is ON or
OFF for the analogue inputs. The first four digits
indicate if the high limit setting is exceeded and
the last four digits indicate if the low limit setting is
exceeded:
A delay time can be set individually for each
analogue input in that the the input can exceed the
limit for a short period without activating an alarm.
An empty square is displayed when the limit is
not exceeded. When the limit is exceeded, a solid
square is displayed. If a delay period is set, the
square will flash during the delay period.
5.5 F4 - Analogue input value #
Menu F4 indicates the value of the analogue inputs
as a bargraph:
Select the desired input with the arrow keys or
the numeric keys.
5.5.1 F5 - Analogue input scaling
Menu F5 indicates the value of an analogue input
as a percentage and the mA signal and as a
scaled value:
Select the desired input with the arrow keys or
the numeric keys.
The scaled value is determined by the
programming of the analogue input.
If the value represents e.g. a level measurement
in a tank, and the level normally varies between 2
m and 3 m, the analogue input will normally be
programmed so 2 m corresponds with '200' (low
value) and 3 m corresponds with '300' (high
value).
A level of 2,5 m will then give a scaled readout of
250 and 50 %.
If the scaled value should be shown as '2,5', it is
possible to set a divisor for each input. In this
example the divisor should have the value 100.

5.5.2 F5 - Analogue input on Pump Controller 704
Menu F2 followed by 1 x 'down arrow' display
the value of the analogue input on the Pump
Controller 704 (if connected):
Please observe that the value is collected directly
from the Pump Controller 704 and is not scaled.
5.6 F6 - Counter for inputs
Whenever a digital input or an analogue high/low
limit is active, it will be recorded by a counter. The
number is displayed in menu F6:
Use the arrow keys to change between:
- digital input 1 - 8/12/16
- analogue high limit 1 - 4
- analogue low limit 1 - 4
In addition, the numerical keys 1 - 8 can be used
to select the desired input.
The selected counter can be reset by pressing
the ENTER key.
5.7 F7 - Counter for time
Menu F7 indicate for how long the digital input
and the analogue high and low limits have been
active. Time counters is running continuously
such as if the input is set to OFF for some time
and then is set to ON, the counter will count from
the last value. The time is displayed in hours and
minutes:
Use the arrow keys to change between:
- digital input 1 - 8/12/16
- analogue high limit 1 - 4
- analogue low limit 1 - 4
In addition, the numerical keys 1 - 8 can be used
to select the desired input.
The selected counter can be reset by pressing
the ENTER key.
