2.2 Wiring

DANGER
The minimum connection reguired for the one-reel unwinding are as follows :
1. Connect AC100 to 240V 50/60 Hz power supply to power supply terminals PSL and PSN. The power
consumption is 400VA when the output of the power amplifier is at the maximum .
2. Perform the solid grounding to the ground terminals and metal plate according to Class D grounding.
3. Connect the tension detector.
4. If the actuator is a powder type, connect it between terminals P and N. If it is a torque-controllable
servomotor, connect it between terminals SA and SN. If it is an electric-pneumatic regulator of 4-
20mA, connect it between terminals EAP and EAN.
5. Connect the Run/stop signals to the terminal MC1.
When using other functions, refer to Section 6 and after.

Wiring of Tension Detector
• The figure on the right shows the connection diagram when the load is applied to the detector in
the compression direction.
When the load is applied in the tension direction, exchange the terminals GRR and WHR each
other as well as the terminals GRL and WHL each other.
• When one tension detector is used, connect it to the right side. And make sure to short-circuit the
terminals GRL and WHL on the left side.
• Set the emergency stop circuit outside the tension controller. If the tension con-
troller performs malfunction, the unit may become out of order and an accident
may occur in the case in which the emergency circuit is built in the unit.
Connect the AC power supply to the terminals PSL and PSN as shown in the
figure above.
• If the AC power supply is connected to the I/O terminal or DC supply terminal, the
tension controller will be burn out.
Do not use the spare terminal for an external device. Otherwise, the unit may
be damaged. Perform the solid grounding to the ground terminal and FG using a
wire of 2mm2 or more.
• Never perform grounding together with the strong power system. Otherwise, mal-
functionmay be caused.
