Tunnel Error:
Tunnel Auxiliary
would be when the controller has seen a closed signal from the tunnel curtain
during tunnel. After 20 seconds the system will come out of tunnel and return to natural or
power ventilation.
Nat Auxiliary
would be when the controller has seen an open signal from the natural curtains
during tunnel or that the curtains never closed from natural allowing the system to go into
tunnel. This alarm would take 13 minutes from when it started to go into tunnel. After 20
seconds the system will come out of tunnel and return to natural or power ventilation.
Low Pressure
would be when the pressure fell below the low pressure alarm setting during tunnel.
This alarm will need to see the pressure below the limit for 45 seconds. At this point the
Alarm Status LED will start blinking. Then after another 20 seconds the system will come out
of tunnel and return to natural or power ventilation.
High Pressure
would be when the pressure went above the high limit alarm setting during tunnel.
This alarm will need to see the limit exceeded for 45 seconds. At this point the Alarm Status
LED will start blinking. Then after another 20 seconds the system will come out of tunnel and
return to natural or power ventilation.
Possible Reasons for Tunnel Vent Alarm Conditions
:
Tunnel Inlet failed to open.
Natural Curtain failed to close.
High Static Pressure due to lack of inlet opening.
NOTE:
Due to the nature of these errors, the control tunnel enable must be reset in order for the
control to re-enter tunnel. Be sure to check the cause if this is a reoccurring problem.
