Use the ↑ and ↓ pushbuttons to select 0-10V (or 0-5V). Press the ENT pushbutton. Press the ESC
pushbutton to return to normal operation. Does the temperature indicated by the control system match the
transmitter display?
DONE 11.
AOUT affects the output of all analog output signals. If the airflow output signal is connected to a device
with a different input signal configuration, the airflow output signal will no longer be compatible with the host
input device.
11
Check the output jumper position for OUT2 (AO2) on the main circuit board. Is the jumper configured for
VDC?
13. 12.
12
Configure the jumper OUT1 for VDC. Does the temperature indicated by the control system match the
transmitter display?
DONE 13.
13
Press the ↑ and ↓ pushbuttons simlultaneously to enter the setup menu and retrieve the AO2 MS and AO2
FS parameters (Section 3). Press the ESC pushbutton to return to normal operation. The full scale of the
host control system should be equal to the AO2 FS parameter and the minimum scale should be the AO2
MS parameter. If the controller uses span and offset in lieu of full scale and minimum scale, the span is
equal to AO2 FS minus AO2 MS and the offset is equal to AO2 MS. Is the host control system setup
properly?
CALL 14.
14
Correct the host control system signal conversion. Does the temperature indicated by the control system
match the transmitter display?
DONE CALL
1. Press the ↑ and ↓ pushbuttons simlultaneously to enter the setup menu and retrieve the AO2 ASGN
parameter (Section 3). Press the ESC pushbutton until the transmitter returns to normal operation. Is the
AO2 ASGN parameter set to TEMP?
3. 2.
2. The transmitter has been field setup to use AO2 for a second location or as a binary airflow alarm or a
system status alarm. Verify the desired function of AO2 before making any changes. If temperature output
is desired on AO2, change the AO2 ASGN parameter to TEMP and use the values for the AO2 MS and
AO2 FS parameters to determine the temperature at the host control system.
3. Is the control system configured for a 4-20 mA input? 4. 6.
4. Simultaneously press the ESC and ↑ pushbuttons during normal operation to determine the setting for
AOUT. Is AOUT set to 2-10V (or 1-5V)?
9. 5.
The 1-5 VDC and 2-10 VDC outputs can drive a 250 ohm and 500 ohm, respectively, 4-20 mA input circuit
5. Use the ↑ and ↓ pushbuttons to select 2-10V (arcross a 500 ohm load) or 1-5V (across a 250 ohm load).
Press the ENT pushbutton. Press the ESC pushbutton to return to normal operation. Does the airflow
indicated by the control system match the transmitter display?
DONE 9.
AOUT affects the output of all analog output signals. If the airflow output signal is connected to a device
with a different input signal configuration, the airflow output signal will no longer be compatible with the host
input device.
6. Is the control system configured for a 0-10 VDC (or 0-5 VDC) input? 7. CALL
7. Simultaneously press the ESC and ↑ pushbuttons during normal operation to determine the setting for
AOUT. Is AOUT set to 0-10V (or 0-5V)?
9. 8.
