4. Alarm from point (also for service)
With this setting the alarm from a point can be suppressed.
The default setting will be "No" – which means that alarms are
received from the point.
Select the "Yes" setting if an irritating alarm needs to be stopped
during servicing. After 12 hours, the setting will automatically
return to "No".
5. Log
This is where you define whether the point’s readings should be
saved.
Off: No collection
On: This is where the actual value for each interval is saved. (The
interval times can be: "15", "30", "60", "120" or "240" minutes. The
times are fixed and cannot be changed.)
"Selected for print": This is where the actual values are saved so
that they can also be printed out.
If not all 65 points are set up with log collection a number of dif-
ferent service logs can be defined. The capacity determines how
many. Follow the remaining capacity when the setup is done from
the "Service tool".
6. Log sample rate
This is where you set how often the measured value is to be saved.
A reading is stored for one year. It is overwritten once a year
has passed.
Choose between 15 mins., 30 mins., 1 hour, 2 hours or 24 hours.
Examples of the capacity:
approx. 57 measuring points @ 15 mins. corresponds to one year.
approx. 50 measuring points @ 15 mins. + 15 measuring points @
30 mins. correspond to one year.
Fewer measuring points and/or longer interval times will not cre-
ate problems, but if you exceed the guidelines and thus the capac-
ity, you will get a configuration error. See overleaf.
7. The measuring point’s address on the data communication
There should only be one setting here if the reading is produced
with one of the three data communications: LON, MOD or TP. E.g.
from an EKC controller, an m2+ unit or a gas unit. The measure-
ment may also come from a wireless unit via the TCP/IP input.
Set the address.
The setting 00:000 is a reading connected directly to the AK-SM
350 unit. All other settings mean that the reading is retrieved from
the address given in the setting. (When an address is set, the digit
"00:" is automatically set to "01" or "11". This setting cannot be
changed.)
8. Input no.
Should only be set if the reading is directly connected to the
monitoring unit’s terminals or to the terminals of an m2+ unit.
This is where you specify which set of terminals is to be used.
The
following settings only apply if "Temperature" was selected in point 3.
9. Type = TEMPERATuRE
Only with sensors that are directly connected to the monitoring
unit or to an m2+ unit.
The sensors can be:
Pt, 1000 ohm at 0°C
PTC, 1000 ohm at 25°C
NTC, 5000 ohm at 25°C
PT1: Thermistor -80 at 0°C
PT2 : Thermistor -40 at 40°C
PT3 : Thermistor 0 at 100°C
10. Alarm limit for too high temperature
Set the temperature value at which the alarm will occur.
(The setting will also be used for scaling the graph display.)
11: Alarm limit for too low temperature
Set the temperature value at which the alarm will occur.
(The setting will also be used for scaling the graph display.)
12. The delay time for the alarm
The alarm will not occur until the temperature value has been
exceeded for the number of minutes specified. Set the number of
minutes required.
