3. Insert a cable through cable connector in YT-2300.
4. Use ring type as cable terminal in order not to come out.
5. Insert terminal bolts in terminal holes of cable and lock them with + terminal and -
terminal each on terminal plate. Tighten terminal bolts with 1.5Nm (15kfgcm) torque.
6. Be sure not to change the polarity of terminal.
Inner terminal connection for ground
1. The ground is necessary for the safety of YT-2300 series and system.
2. There are inside terminal in the center of terminal plate and outside terminal beside
outer cable entry. Using any ground terminal is available and resistance must be less
than 1000hm.
Ground terminal connection
3. In case of using inside ground, open cover by loosening 4pcs of M4 bolts of product
cover.
4. In order to maintain the ground safely, use ring type as ground cable terminal to
prevent it coming out.
A/M switch (Auto/Manual switch)
There is A/M switch on the bottom of YT-2300. If this switch is set as auto, supply
pressure is transmitted to actuator by the operation of YT-2300 and if it is set as
manual, supply pressure of air filter regulator is transmitted to actuator regardless of
YT-2300.

* When A/M switch is set as manual, ensure that too much pressure must not be
transmitted to the actuator.
1. Check if the supply pressure of air filter regulator is too high.
2. Turn the switch clockwise and supply pressure of air filter regulator is transmitted to
actuator.
3. If turn the switch counter-clockwise, YT-2300 is operated normally.

Adjustment of A/M switch
Variable orifice
The actuator volume is too small, hunting can be occurred. In this case, adjust variable
orifice with using (-) driver, then hunting is prevented by reducing flow rate of supply
pressure transmitting to actuator.
