TERMINAL CONNECTIONS
Connect the unit as in the diagram below or refer to the con-
nection diagram on top of the unit.
CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
7 – 8 with a multimeter.
3) Input: Check voltage across the input terminals 5 (+) – 6
(–) with a multimeter.
4) Output at STOP signal OFF: The output does not track
the input signal.
5) Output load: Check that the load resistance meets the
described specifications.
ADJUSTMENT PROCEDURE
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) Reset all setting.
2) Turn the unit into Program mode.
3) Simulate 0% input and adjust the PV display to show 0.0
(ITEM 04).
4) Simulate 100% input and adjust the PV display to show
100.0 (ITEM 05).
5) Simulate 0% input again and check the PV display.
6) When the PV value is changed, repeat the above proce
-
dure 3) – 5).
7) Simulate 0% input and adjust the output to 0% (ITEM
06).
8) Simulate 100% input and adjust the output to 100%
(ITEM 07).
9) Simulate 0% input again and check the output.

) When the output value is changed, repeat the above pro
-
cedure 7) – 8).
11) Return the unit into Monitor mode.
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.
