This Instruction Manual describes matters to be attended to concerning safety, potential damage to equipment
and/or facilities, additional explanations and notes under the following headings.
WARNING: This heading indicates that failure to follow instructions could cause injury or even death.
CAUTION: This heading indicates that failure to follow instructions could causedamage to equipment and/or facilities.
The EM51 Series Servo Controller is designed for controlling
temperature, humidity and other physical quantities in general
industrial facilities. Therefore, it should not be used in any way
that might result in injury or fatality, or must be used only after
adequate safety measures are taken. No responsibility will be
taken for any accident resulting from the usage of this device
without appropriate safety measures being in place.
•This device must be housed, for example, in a control box to
prevent the terminal board from coming into accidental phys-
ical contact with personnel.
•To prevent electric shock, always turn off and disconnect this
device from the power supply before starting wiring.
•Do not touch wired terminals or charged parts with your hands
while the power is supplied.
WARNING
To avoid damage to connected peripheral devices, facilities or
the product itself due to malfunction of this device, safety coun-
termeasures such as proper installation of the fuse or installation
of overheating protection must be taken before use. No respon-
sibility will be taken for any accident resulting from the usage
of this device without appropriate safety measures being in
place.
•The Alert Symbol Mark on the plate affixed to this device:
The Alert Symbol Mark indicated on the nameplate affixed
on the casing of this device warns you not to touch charged
parts while this device is powered ON. Doing so might cause
an electric shock.
•A means for turning the power OFF such as a switch or a
breaker must be installed on the external power circuit con-
nected to the power supply terminal on this device.
Fasten the switch or breaker at a position where it can be eas-
ily operated by the operator, and indicate that it is a means
for powering this device OFF.
•Use this device by ensuring the wire connection part is firm-
ly tightened.
•Fuse: This device has no built-in fuse. Ensure to install a fuse
in the power circuit to be connected to the power supply ter-
minal.
Fuse rating/characteristic: 250V AC 0.5A
•Use the device with the power voltage, frequency, load current
and voltage within their rated ranges.
•Use the device with the relay contact current only within its
rated range. When using with any motor, use only within
approx. 1/5 of the rated range since inrush current or surge
voltage may occur.
•Users are prohibited from remodeling this device or using it
in a prohibited or unauthorized manner.

3. Installations
Do not use this device in the following sites to avoid any trouble since
use in such circumstances may generate severe harmful influence on
its performance or its useful life, or lead to other shortcomings:
1. Locations that are filled with or generate corrosive gas or inflam-
mable gas
2. Locations where high temperature/humidity is present
3. Locations where direct sunlight or radiant heat such as that from
an electric furnace is present
4. Locations where any vibration or shock may be experienced
4. External Dimensions & Panel Cutout
6. Wiring
1. Wiring should be routed according to the indications located on
the terminal face plates.
Do not apply too much force when tightening the terminal screw.
2. Keep wiring away from strong electrolyte circuits, or use shield-
ing wire to protect the feedback resistance wire from the input
signal/control motor.
3. If you inadvertently connect the motor power supply to the feed-
back resistance circuit of the control motor, the potentiometer will
burn.
4. Connection terminal symbols found on control motors may vary
depending on their manufacturer. Refer to the instruction man-
ual supplied by the manufacturer in question for clarification.

7. Connection Diagram
*For model with Triac (SSR), motor
power supply voltage range must be 20
~ 120V AC.
It is recommended that the fuse between
terminaland the power supply termi-
nal be used to protect motor upon mal-
function.
(Current rating for fuse must be approx-
imately twice the size which is appro-
priate for the motor for which it is being
used.)

CONTACT TRIAC
• Make sure the motor power supply matches the rating of the motor to be used.
• For inverting the operating direction of motor (to open with input at 0% and close with
input at 100%), permute the wires for terminals and as well as those for termi-
nals and respectively.

8. Adjustment
8-1. Characteristic of Input Signal vs. Operating Output
8-2. Adjustment of Operating Output
Confirm that the final control element is at 100% or the open position when 100% input signal is applied and at 0% or the closed posi-
tion when 0% input signal is applied.
If there is any dislocation at the 0% position, adjust the Zero trimmer. In the case of dislocation at the 100% position, adjust the Span trimmer.
Note: Since the reaction of the final control element is normally slow, adjust the Zero and Span trimmers slowly.
8-3. Adjustment of Deadband (DB)
The deadband refers to the sensitivity between the clockwise (open) and counterclockwise (close) actions of the control motor.
If the control motor repeats quick hunting, turn the deadband from the narrow band gradually to the wide band until hunting stops.
If the deadband is set unnecessarily wide, the control motor may be dull in response.
(The deadband may be variable within 1 to 10% of the input signal range.)
