Changing Loop Current to a Fixed Value
The “Diag/Service” menu allows you to change the
loop current to a fixed output. Once the TRZ’s output
current is set to a known value, it can be checked
against the value being received and displayed by
your receiving device.
To change the loop current to a fixed value:
1.
Highlight DEVICE SETUP in the Main Menu
and push the right arrow.
2.
Highlight DIAG/SERVICE and push the right
arrow.
3.
Highlight LOOP TEST and push the right arrow
to change the loop current to a fixed output.
Note:
The TRZ has to be removed from
automatic control in order to run the Loop
Test.
4.
Push OK after removing the loop from
automatic control.
5.
Choose the current output value and push
ENTER. Push OK if the entry is correct, abort
if it is not.
6.
Highlight “End” and press “Enter”. Push OK to
return the loop to automatic control. The
screen returns to the Diag/Service menu.
7.
Push HOME to return to the Main Menu.
Trimming the Input Sensor
From the “Sensor Trim” menu, you can enter the
offset for a non-calibrated sensor or reset the TRZ to
the factory settings.
Offset for non-calibrated sensors can be entered two
different ways. The first time a non-calibrated sensor
is connected, SENSOR TRIM is used to enter the
offset because it allows the TRZ to synchronize with
the input. Subsequent adjustments to the offset can
be accomplished in SENSOR TRIM or in OFFS.
SENSOR TRIM can only be used in a controlled
environment because fluctuating input makes it diffi-
cult for the TRZ to synchronize with the input. OFFS
can be used in a controlled environment or in the
field.
To trim the sensor:
1.
Highlight DEVICE SETUP in the Main Menu
and push the right arrow.
2.
Highlight DIAG/SERVICE and push the right
arrow.
3.
Highlight SENSOR TRIM and push the right
arrow to start the trim process.
Note:
To change the offset without
synchronizing to the input, skip to step 8.
To reset the TRZ to the factory settings,
go to step 9.
Before beginning Sensor Trim, the TRZ
reverts to the factory trim settings. This
takes 5 seconds. Pushing Abort during
this time stops the process.
5.
After reverting to the factory settings, the TRZ
will synchronize with the input. Adjust the input
until the desired value appears, then press OK.
6.
A space appears below the input value. Input
the desired offset value into the space and
press ENTER to return to the Sensor Trim
menu.
