Setting Sash Area Alarms
21
Siemens Industry, Inc. Start-up Procedures 140-1321
Restricted 2015-11-04
NOTE:
If no external area input will be connected to AI 3, make sure MAX EXT AREA = 0
(default). This disables the alarm feature that would fail the FACE AREA point the
input signal dropped below 1 Vdc. When MAX EXT AREA = 0, AI 3 is then available
for other uses.
Setting Sash Area Alarms
The fume hoods can be set up to chirp if the sashes are opened beyond a certain limit.
It is used to remind the user to keep the sashes closed to save energy. Skip this step
unless there is a special requirement on the job; the default will be used.
1. Change Report to ATTN.UNATTN.
2. Set UN ALRT AREA and AT ALRT AREA. These values correlate to the open face
area. ATTN.UNATTN is connected to DI2. When DI2 is open, the controller is in
ATTN mode and the alarm limit uses the area AT ALRT AREA, and when the
controller is in UNATTN mode the alarm limit uses the area UN ALRT AREA.
3. Set the OPEN TIME to the desired attended time delay between when the user
presses the horn silence button and restarting of the ODP beeps. Values are in 1
SEC increments. Valid values are 0 through 1023.
4. Set SASH TONE to OFF in order to disable the audible beeping of the sash alarm
function. This only disables the horn while in ATTN mode only. To disable this
feature, set the AT ALERT AREA to a value larger than the maximum face area.
(Optional) Setting Damper Control — Application 2941
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.
Checkout of Damper — Application 2941
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.
