TEST SIGNAL
This option submenu outputs a fixed 4, 10, and 20 mA
value to each output. This test checks the output signal
from the DMPR-RA002 Electronic Controller for
velocity and temperature. Make sure that a user is
present at the BAS computer to verify that the
appropriate test signal from the DMPR-RA002
Electronic Controller is reaching the BAS computer.
To turn a test signal ON, press ENTER from the Option
menu to access the TEST SIGNAL options. Use UP
and DOWN to select the SET TEST SIGNAL: YES
option. Use UP and DOWN to scroll through each of
the available fixed output signals (4, 10, or 20 mA).
Press ENTER to accept the test output signal and turn
the test signal ON. See Figure 18.
Note:
Connect the BAS wiring and verify the test
signal at the BAS and automation scaling have been
correctly configured. If the test signal at the BAS does
not produce expected results, disconnect the BAS
wiring and verify the test signal at the controller with a
multimeter. If the test signal at the controller is not
correct, contact the factory for additional calibration
procedure instructions.
To turn the test signal OFF, press ENTER or EXIT.
