Setting Emergency Setpoint
Skip this step unless there is a special requirement on the job, the default will be used.
Set EMER STPT to a value of 0 through 255%; default value is 150%.
This percentage, multiplied by the normal EXH STPT, is used to set the fume hood
to a safe operating level during the second phase of the emergency purge
sequence.
NOTE: If EMER STPT is set to a value less than 100%, the exhaust flow will be
reduced during the emergency purge sequence.
Setting Emergency Timer
Skip this step unless there is a special requirement on the job, the default will be used.
Set EMER TIMER to a value of 0 through 32,767 seconds; default is 300 seconds.
This is the time the fume hood will be at full exhaust during the first phase of the
emergency purge sequence.
NOTE: If EMER TIMER is set to zero, the FHC immediately sets the exhaust flow
to EMER STPT when the emergency purge button is pushed.
Setting Damper Control
Skip this step if you are using high speed actuators from Siemens Industry, Inc.
The application has the option of not inverting DO2 operation. An inverted RETC DO2
means that to hold a position, the RETC DO2 must remain on.
Set INVERT DO2 by selecting one of the following:
– YES to invert RETC DO2 (default).
– NO for non-inverted operation.

1. Set DMPR CMD to 100.0. The damper moves to the fully opened position.
2. Set DMPR CMD to -100.0. The damper moves to the fully closed position.
3. If the damper moves opposite of the way it should, reverse the wires on EXTN DO1
and RETC DO2 on the FHC terminal block.
4. Release DMPR CMD. Verify the point has been released.
(Optional) Setting Airflow Input Type
If you are using a Siemens terminal box/Venturi valve with an OAVS sensor, you can
skip this section.
Otherwise, if the job uses differential pressure sensors, Vortex shedders or another
linear device made by others, perform the steps in this section.
NOTE: When using AI-3 to input the airflow, the input can’t be used as an input for
External Face Area.
