WIRING INSTRUCTIONS
■SCREW TERMINAL
Torque: 0.8 N·m
CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage supplied to the rack
(model: 10BXx). For the DC power source, be sure that
the ripple level is within 10% p-p.
3) Input: Check voltage across the terminal 2 (+) – 3 (–)
with a voltmeter to show 0V at 0% potentiometer input
and the same voltage as that across 1 (+) – 3 (–) at 100%
input.
4) Output: Check that the load resistance meets the de-
scribed specifications.
ADJUSTMENT PROCEDURE
This unit is calibrated at the factory with the total resist-
ance input, therefore you do not need any calibration if you
use the potentiometer’s total resistance.
When you do not use the total resistance or in case of regu-
lar calibration, adjust the output as explained in the fol-
lowing.
■HOW TO CALIBRATE THE OUTPUT SIGNAL
Use a signal source and measuring instruments of sufficient
accuracy level. Turn the power supply on and warm up for
more than 10 minutes.
1) ZERO: Apply 0% input and adjust output to 0%.
2) SPAN: Apply 100% input and adjust output to 100%.
3) Check ZERO adjustment again with 0% input.
4) When ZERO value is changed, repeat the above proce-
dure 1) – 3).
5) Go through the same procedure for Output 2. Extender
Card (model: 10EC) is required to access the Output 2
Adjustments on top of the unit maintaining electrical
connection at the rear connector.
MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accu-
racy described in the data sheet. When the output is out of
tolerance, recalibrate the unit according to the “ADJUST-
MENT PROCEDURE” explained earlier.
