Adjustment Procedure for the CRT1-TS04P
Adjustment Procedure
Use the following procedure to adjust the Temperature Input Unit. Follow the
flowchart closely for proper adjustment.
Note
Only sensors that operate while the power supply is ON can be adjusted.
When adjusting sensors that are not presently in use, change the input type
setting, reset the power or CX-Integrator, and then perform the adjustment
procedure from the beginning of the flowchart.
Connecting the
Devices Required for
Adjustment
The following paragraphs explain how to connect the devices that must be
connected to the Temperature Input Unit for user adjustment. Wire the follow-
ing devices properly when making adjustments.
Six-dial Resistance Box and Precision Digital Multimeter
These devices are used to make adjustments at the upper limit and lower
limit. Prepare devices that can provide accurate resistance values.
Use a precision digital multimeter that can measure the resistance values and
indicate when the six-dial resistance box is not producing an accurate resis-
tance.
Yes
No
Prepare the device required for adjustment.
Connect the adjustment devices.
To make the upper/lower limit adjustment, connect a
six-dial resistance box to the Temperature Input Unit
that is being adjusted.
Turn ON the power to the system devices.
Wait at least 30 minutes for the internal
temperature to stabilize.
Set the input's lower limit adjustment value.
Set the input's upper limit adjustment value.
Adjust other inputs?
Test indication accuracy after adjustment.
