Yes No
9. Press the ↑ and ↓ pushbuttons simlultaneously to enter the setup menu and retrieve the AO3 UM, AO3 MS
and AO3 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 AO3 FS parameter and the minimum scale should
be the AO3 MS parameter. If the controller uses span and offset in lieu of full scale and minimum scale, the
span is equal to AO3 FS minus AO3 MS and the offset is equal to AO3 MS. The units of measure are
equal to the AO3 UM parameter. Is the host control system setup properly?
CALL 10.
This information can easily be retrieved using the EB-Link Reader application for Android® an iOS® phones
or tablets (Section 4).
10
Correct the host control system signal conversion. Does the psychrometric value indicated by the control
system match the transmitter display?
DONE CALL
1. Is a standard RJ-45 terminated Ethernet cable, CAT5 or greater firmly seated in the output card Ethernet
10/100 connector? (refer to the appropriate Wiring Guide for the Ethernet 10/100 connector location.)
3. 2.
2. Connect a standard RJ-45 terminated Ethernet cable, CAT5 or greater to the output card ETHERNET
10/100 connector. Is the transmitter found on the network?
DONE 3.
3. Is the activity led on the output card flashing? (refer to the appropriate Wiring Guide for activity led location) 7. 4.
4. Move the power switch to the "OFF" position. Check that the output card below the LCD is properly seated
on
the main circuit board. Is the output card properly seated?
CALL 5.
5. Check pins on the main circuit board for damage. Are the pins damaged? CALL 6.
6. Properly seat the output card on the pins. Move the power switch to the "ON" position. Is the activity led on
the output card flashing?
7. CALL
7. Is the link led on the output card illuminated? (refer to the appropriate Wiring Guide for link led location) 8. CALL
8. Verifiy that all Ethernet network settings are correct (Section 3). Are the Ethernet network settings correct? CALL 9.
9. Set the Ethernet settings to proper values. Is the transmitter found on the network? DONE CALL
1. Is a 3-conductor network cable meeting the corresponding BACnet or Modbus standards connected to the
output card terminal block with terminal screws secure with no shorts between wires (refer to the appropriat
Wiring Guide for terminal block location.)
3. 2.
2. Move the power switch to the "OFF" position. Properly connect a 3-conductor network cable meeting the
corresponding BACnet or Modbus standards to the output card terminal block. Move the power switch to the
"ON" position. Is the transmitter found on the network?
DONE
3.
3. Move the power switch to the "OFF" position. Check that the output card below the LCD is properly seated
on the main circuit board. Is the output card properly seated?
6. 4.
4. Check pins on the main circuit board for damage. Are the pins damaged? CALL 5.
5. Properly seat the output card on the pins. Move the power switch to the "ON" position. Is the transmitter
found on the network?
DONE 6.
6. Is the transmitter the first or last device on the network run? 7. 8.
7. Verify the network termination is set to either Fail-Safe Bias for first device or End of Line for last device.
(refer to the appropriate Wiring Guide for termination switch location) Is the transmitter found on the
network?
DONE 9.
8. Verify the network termination is set to No Termination. (refer to the appropriate Wiring Guide for termination
switch location) Is the transmitter found on the network?
DONE 9.
9. Verifiy that all RS-485 network settings are correct (Section 3). Are the RS-485 network settings correct? CALL 10.
