3. GENERAL
This UZ011 is a plug-in type Analog Positioner.
• Internal timer prevent frequent ON-OFF of motor valve.
•
Retransmission output can be used to monitor the motor position value.
• Feedback slide resistance : 100 ⍀to 10 k⍀
• Easy adjustment operation, ⫾1% Setting Accuracy.
4. MOUNTING METHOD
NOTE
Insert/pull out the main unit into/from the socket vertically
to the face of socket. Otherwise the terminals are bent and
it may cause a bad contact.

4.1 Wall Mounting
Remove the stoppers (top and bottom) from the product and pull out
the main unit from the socket. Fix the socket on the wall using two M4
screws. Next, insert the main unit into the socket and fasten the main
unit with the stoppers (top and bottom).

Note:
(1) More than 5 mm interval is
required for side-by-side
close mounting.
(2) Use the supplied spacer for
DIN rail mounting to keep 5
mm interval.
4.2 DIN Rail Mounting
Insert a DIN rail into the upper part of the DIN rail groove on the rear of
the socket, and then slide the slide lock at the lower part of the socket
upwards until the socket is fixed into position as shown below.

5. INSTALLATION LOCATIONS
●Avoid the following environments for installation locations:
Areas with vibration, corrosive gases, dust, water, oil, solvents, di-
rect sunlight, radiation, a strong electric field, and/or a strong
magnetic field
●If there is any risk of a surge being induced into the power line
and/or signal lines due to lightning or other factors, a dedicated
lightning arrester should be used as protection for both this unit
and a field-installed device.
6. EXTERNAL WIRING
WARNING
To avoid the risk of an electric shock, turn off the power
supply and use a tester or similar device to ensure that no
power is supplied to a cable to be connected, before carring
out wiring work.
Wiring should be connected to the terminals on the socket of the prod-
uct. The terminals for external connections are of M3.5 screws. Use
crimp-on terminal lugs for connections to the terminals.
●Recommended cables: A nominal cross-sectional area of 0.5 mm2
or thicker for signal cables, and that of 1.25 mm2 or thicker for
power cables.
(1) Position setpoint input signal's terminals are No.5 (⫹) and No.6 (⫺).
(2) Control output signal's terminals are No.1 (H), No.2 (L) and No.3
(COM).
(3) Position feedback input signal's terminals are ;
•When the slide-wire resistance is used: No.9 (100%), No.10
(CTR) and No.11 (0%).
•When analog signal (1 to 5V DC or 4 to 20mA DC) is used: No.10
(⫹) and No.11 (⫺).
(4) Power supply's terminals are No.7 (L⫹) and No.8 (N⫺).
(5) Retransmission output signal's terminals are No.4 (⫹) and No.6 (⫺).

IMPORTANT
●
The power line and input/output signal lines should be
installed away from noise-generating sources. Other
wise accuracy cannot be guaranteed.
●
Use of the product ignoring the specifications may
cause overheating or damage. Before turning on the
power, ensure the following:
(a) Power supply voltage and input signal value applied
to the product should meet the required
specifications.
(b) The external wiring to the terminals and wiring to
ground are as specifications.
●
Do not operate the product in the presence of
flammable or explosive gases or vapors. To do so is
highly dangerous.
●
The product is sensitive to static electricity; exercise
care in operating it. Before you operate the product,
touch a nearby metal part to discharge static electricity.
●
Connect the external resistor (shunt resistor) when the
signal of the "Position setpoint input" or the "Feedback
input" is 4 to 20mA DC.
7. ADJUSTMENT
Zero adjustment
Open
the front panel
(cover)
Span adjustment
Dead band adjustment
Timer adjustment
WARNING
To avoid electric shock, do NOT touch internal components
when adjusting the instrument with its front panel (cover)
removed.
The product starts running immediately when the power is turned on;
however, it needs 10 to 15 minutes of warm-up before it meets the
specified performance.
7.1 Zero and Span Adjustments
Perform the zero and span adjustments so that 0% and 100% retrans-
mission outputs are obtained. (In general, 0% and 100% outputs are
valve fully-closed and fully-open, respectively.)
7.2 Deadband Adjustment
The deadband is the range (differential in an input signal) until the H
(direct) or L (reverse) relay turns on. Adjust the deadband in the range
from 1 to 20% if an undersired change (disturbance) or hunting ad-
versely affects the operating points. This deadband is adjusted to a
maximum (20%) at the factory before shipment. Adjust the deadband
as narrow as possible (in an appropriate range to minimize outputting a
drive signal) by observing the control line status and stability of motor-
driven part operations.
7.3 Timer Adjustment
The timer-adjutment time is the time taken to enable the H or L relay
after it has been turned off. That is, it is the time during which a relay
output cannot be issued in order to prevent the motor from being over-
heated by frequently turning on and off the relays. Thus, there is a cer-
tain time until the motor can be restarted. Appropriately adjust the
timer-adjustment time between 1 and 30 seconds such that the relay
does not turn on and off too frequently. The timer-adjustment time is
adjusted to a minimum at the factory before shipment.
