5.13.2.4 Adjusting Static Pressure Alarms
The controller can generate an alarm if the static pressure drops below
the low pressure limit or if it exceeds the high pressure limit. The control-
ler uses a delay before activating the alarm. If the static pressure
exceeds the high or low limits for that delay, an alarm is generated.
LO STATIC PRESSURE ALARM:
The user can assign a relay that will be activated when a Low Static
Pressure Alarm occurs. This relay may activate a fan output for in-
stance. When this type of alarm occurs, the relay turns on for a 15
minute delay. If the static pressure level is still below the Low Pressure
Limit after the delay has elapsed, the relay remains activated for another
15 minutes, up until the pressure level goes back into the normal range
once again.
Set the Lo Alarm Limit to Off to deactivate this feature.
HI STATIC PRESSURE ALARM:
When a high static pressure alarm occurs, the controller can open both
vent doors and the tunnel curtain. The curtain or vent doors open during a
user-defined delay (Open-Time) and then stay still for a total time of 15
minutes (this time includes the Open-Time). If the pressure level still
exceeds the Hi Static Pressure Limit after this delay, the same cycle starts
over again, up until the pressure level goes back into the normal range.
Adjusting Hi/Lo Static Pressure Alarm Limits
Set the function to "21.Alarm Limits" from the main menu using the
navigation buttons then press the right-arrow key.
Use the navigation buttons to select "2.Static Pressure" then press
the right-arrow key.
Press the right-arrow key once again in order to select the "1.Hi/Lo
limits" option. The Lo and Hi pressure limits are displayed.
Use the adjustment buttons to set
the Low alarm limit to the desired
value.
