Setra System SRCM - Manual (Page 2)

Operation
The following is a brief summary of how to operate the SRCM using the touch-screen inter-
face. The screen has two basic functions. The primary mode of operation displays the Home
screen, which shows the end-user pressure values, messages, text, and other data intended for
visual pressure verification in the facility. The second mode of operation is the Administrative
Menu (Menu) screen, which permits setup, configuration, and changes to how the SRCM
operates. After changes have been performed on the Menu screen, functions are saved and
operation returns to the Home screen
. The full SRCM Operation Manual is available in .pdf
format on Setra’s website at http://www.setra.com/tra/pro/ins/SRCM Oper.pdf.
Note: With screen tilted up, enable BACnet

1. Network Name
2. Baud Rate: Select one for RS485 comm.
from 9600, 19200, 38400, 76800 by using
the change button.
3. MAC Address: Enter Medium Access
Control address value from 0 to 127 as this
unit is a BACnet master.
1. Latch Alarm: Causes the display of red ALARM on home
screen to remain, even if room pressurization returns to
normal.
2. Alarm Delay: Time between when the pressure went
outside alarm setpoints and when the unit goes into alarm
mode.
3. Primary or Secondary Room: Defines which room the
Setup alarm condition applies to.
Primary or Secondary: Whether room pressure will be Posi-
tive, Neutral, or Negative
4. Audible Alarm: Enables or disables audible buzzer.

Banner by pressing anywhere in the
colored region.
2. Configure whether the user can change
the text of the Condition Banner:
Enabled or Disabled
3. Room Status: Occupied or Standby
1. Primary Pressure Resolution: The number of significant digits
displayed for the pressure value.
2. Define Supervisor and Operator passwords. Enable or Disable use of
passwords
3. Contrast level of Home screen: Adjust from 1-4 for readability in
varying lighting conditions
1 . Setup Unit: Primary or Secondary

8. Buzzer Volume: Can be adjusted from 1 to four
9. Save settings and exit
Primary Room or Secondary: Screen is used to define the alarm setpoints. When the room
is then set to Positive, Neutral, or Negative, the setpoints and conditions configured here
are in effect for alarm and warning conditions. 6. Analog Output Signal: 4-20mA, 0-5 or

1. Zero Adjust Pressing Zero Adjust button: “Is zero pressure applied?” message appears.
If yes, press OK. If measurement is within 10% of factory zero stored, the zero
value will reset.
2. Span Adjust This requires the use of a Pressure Calibrator, such as a Setra Model 869 or
equivalent. Connect tubing from the Calibrator to the low and high ports identified
near the PCBA markings. Apply Full Range pressure, for example ± 0.1” WC range,
use 0.1” WC. When pressure reaches Full Range pressure, press OK button. The
output at Full Range must be within 10% of the factory calibration to allow
re-adjustment.
3. Restore Factory User Zero and User Span If the unit has been miscalibrated in the field, the factory zero and
span settings can be restored.
4. Test The Buzzer, Relay and Internal Memory checksum can be tested and verified.
4. Isolation Mode: Pressure mode configured for the
unit: Positive, Negative or Neutral.
(To change mode, refer to the Setup Alarm screen)
5. Choose whether certain parts of the screen blink, or
expand banner to full screen
6. Language: Choose English or French
6. Save settings and exit
4. APDU Timout: Indicates the amount of time
in milliseconds between transmissions of an
APDU requiring acknoledgement for which none
has been received. Defualt value 3,000 ms; Max.
value 65535.
5. Save settings and exit
6. After setup, cycle power to save settings (With
screen tilted up, in lower right corner, pull jumper
