20). The pressure regulation continues as normal. If the motor error disappears (clamps 14
and 15 are connected), the motor error in the display will disappear automatically.
2) Pressure/flow alarm above setpoint. If the measured pressure/flow exceeds the desired
regulation setpoint plus an alarm threshold (pressure/ flow se alarm threshold), the
following alarm will be displayed
”ERROR! To high”, and the alarm relay will change state
(Clamps 18, 19, 20). The alarm threshold is set in setpoint menu no. 4. This setpoint is
adjustable from 0Pa to 1000Pa (In air pressure adjustment mode) or from 0.00m/s to
10.00m/s (in air flow adjustment mode). The alarm is, however, only activated if this
condition has been present for a given period of time. The alarm time is adjusted in setpoint
menu no. 5. The time can be set from 0 to 1000 sec. If the pressure/air flow falls below this
treshold again, the alarm will automatically be deactivated. See example in fig 3.1.
3) Pressure/air flow alarm below setpoint. If the measured pressure/ flow falls below the
desired regulation setpoint less an alarm threshold (pressure/air flow setpoint
– alarm
threshold), the following alarm will be displayed
”ERROR! To low”, and the alarm relay will
change state (Clamps 18, 19, 20).The alarm threshold is set in setpoint menu no. 4. This
setpoint is adjustable from 0Pa to 1000Pa (in air pressure adjustment mode) or from
0.00m/s to 10.00m/s (in air flow adjustment mode). The alarm is, however, only activated if
this condition has been present for a given period of time. This alarm time is adjusted in
setpoint menu no. 5. The time is adjustable from 0 to 1000 sec. If the pressure/flow exceeds
this threshold again, the alarm will automatically be deactivated.
