Alarm settings
Here all settings for the alarm system are set including alarm parameters, delays,
suppression times etc.
1. Temperature deviation alarm
Should the actual temperature differ from the setpoint by more than the set
value an alarm will be activated after a set time.
2. Outdoor temperature range within which the temperature deviation
alarm can be activated
To prevent alarms when the outdoor temperature leads to conditions beyond
the system capacity.
Example: If a system for supply air control does not have cooling an alarm
will be given when the outside temperature exceeds 20 to 25 degrees since
the temperature cannot be reduced. To avoid a ”false” alarm the upper
temperature limit is set at 20 degrees in this case. The same is true at the
other extreme. If the outside temperature should fall below the set tempera-
ture a ”false” alarm can be avoided by setting the lowest outside tempera-
ture limit to this temperature.
N.B. This function is not available unless an outdoor sensor is connected to
CORRIGO.
3. Pressure deviation alarm (C20 and C40 only)
Should the actual pressure differ from the setpoint by more than the set value
an alarm will be activated after a set time.
4. Alarm suppression Supply air fan
A fan pressure deviation alarm is suppressed by a set time to avoid the
alarm stopping the fan during start up before the pressure has reached the
normal level.
5. Alarm suppression Exhaust air fan
As for supply air fan above
6. Alarm output suppression
The alarm output relay can be blocked so that unprioritised alarms will only
be forwarded during the set time and not during the night or weekends, for
example. Outside the set period only frost alarm, high temperature alarm and
fire alarm will activate the alarm relay.
Set the times in this menu when alarms are forwarded to the alarm relay
output.
Example: An alarm is only to activate the alarm output between 08.00 and
17.00, Monday to Friday. The setting will be as follows:
N.B. Even if the alarm output is blocked the alarm will be registered and
indicated by the red flashing alarm diode and the alarm list menus will
function as normal.
