unit for separating the body from the base socket.
■ DIN RAIL MOUNTING
Set the base socket so that its
DIN rail adaptor is at the bottom. Position the upper hook
at the rear side of base socket
on the DIN rail and push in the
lower. When removing the
socket, push down the DIN rail
adaptor utilizing a screwdriver
(–) and pull.

OPERATION
MAINTENANCE
• When the STOP signal from the computer (5 – 6) is ON:
The output signal increases with UP signal (3 – 6), and
decreases with DOWN signal (4 – 6). If both UP and DOWN
signals are ON, the output remains held.
• When the STOP signal from the computer (5 – 6) is OFF:
The UP/DOWN signals at the t erminals 3 – 6 and 4 – 6 are
disabled and the CB2 holds the value just before the OFF
signal.
The output signal can be increased or decreased manually by
giving UP (9 – 11) or DOWN (10 – 11) signals ON. If both UP
and DOWN signals are ON or OFF, the output remains held.
Regular calibration procedure is explained below:
■ CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0% and 100%
input signal. Check that the output signal for the respective
input signal remains within accuracy described in the data
sheet. When the output is out of tolerance, recalibrate the
unit according to the "ADJUSTMENT PROCEDURE" explained earlier.
CHECKING
1) Terminal wiring: Check that all cables are correctly
connected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal 7
– 8 with a multimeter.
3) Output at STOP signal OFF: The output does not respond
to UP (3 – 6) or DOWN (4 – 6) signals.
4) Output load: Check that the load resistance meets the
described specifications.
ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any calibration.
For regular calibration, adjust the output as explained in the
following.
■ HOW TO CALIBRATE THE OUTPUT SIGNAL
Turn the power supply on and warm up for more than 10
minutes.
1) Apply DOWN signal input until the output decrease stops
and adjust output to 0% with ZERO Adj.
2) Apply UP signal input until the output increase stops and
adjust output to 100% with SPAN Adj..
3) Check ZERO adjustment again with DOWN signal input.
4) When ZERO value is changed, repeat the above procedure
1) – 3).
The output ramp rate (response time) for UP/DOWN signal
input can be adjusted within approx. 5 to 30 seconds using the
Response Time Adj.
Caution:
DO NOT turn the Response Time Adj. while operating UP/
DOWN buttons.
