Fan Exception alarm
SAF: Active
Flow/pressure of the sup-
ply air deviates from the
setpoint.
Check the set setpoint for air ow/pressure has
been achieved. Check whether the fan is rotating.
Check whether the lter is dirty. Check whether
the damper is open.
Check the ow/pressure alarm limits.
Check/calibrate sensors. Check sensor air
hoses.
Exception alarm
EAF: Active
Flow/pressure of the
extract air deviates from the
setpoint.
Check the set setpoint for air ow/pressure has
been achieved. Check whether the fan is rotating.
Check whether the lter is dirty. Check whether
the damper is open.
Operating period
alarm fan
The supply air fan operating
period has reached the alarm
limit
Reset the operating period meter. Check that the alarm should be active and
if this is the case check the alarm limit.
