Caution
1.This unit shall not be used outdoors. It may give an electric shock. 2.When wire connection, No.20AWG(0.50mm2) should be used and screw bolt on terminal block with 0.74Nm to 0.90Nm strength. It may result in malfunction or fire due to contact failure. 3.Please observe specification rating. It might shorten the life cycle of the product and cause a fire. 4.Do not use the load beyond rated switching capacity of Relay contact. It may cause insulation failure, contact melt, contact failure, relay broken, fire etc. 5.In cleaning the unit, do not use water or an oil-based detergent. It might cause an electric shock or a fire. 6.Do not use this unit at place where there are flammable or explosive gas, humidity, direct ray of the sun, radiant heat, vibration, impact etc. It may cause explosion or a fire. 7.Do not inflow dust or wire dregs into inside of this unit. It may cause a fire or mechanical trouble.

Caution for using

1. Power connection (1) AC Power : It is able to connect power to the terminals(2 to 7) without distinguish the polarity. DC Power : Be sure the polarity of <->, <+>. (2) It can be operating stably due to free power voltage type.(Please connect the power lind seperate from high voltage line in order to avoid inductive noise) 2. Input signal line (1) Shorten the cable distance between the sensor and this product. (2) Please shielded wire for input signal needed to be long. (3) Please wire input signal line separated from power line. 3. When test dielectric voltage and insulation resistance of the control panel with this unit installed. (1) Please isolate this unit from the circuit of control panel. (2) Please make all terminals of this unit short-circuited. 4. Do not use this unit at below places because of product damage. (1) Place where there are severe vibration or impact (2) Place where strong alkalis or acids are used (3) Place where there are direct ray of the sun (4) Place where strong magnetic field or electric noise are generated 5. Installation environment (1) It shall be used indoor (2) Altitude Max. 2000m (3) Pollution Degree 2 (4) Installation Category II

Setting time changes can be made during timing operation. Make sure that timing operation is continuously progressed while changing the setting time. If pressing *key while setting time is shorter than min. setting time, setting value will be flickering three times and it will be returned to setting mode again, not to RUN mode. If there is no additional key operations after entering into setting mode, it will be return to RUN mode.(Setting value is not saved.) Min. Setting time: 0.01 sec.(In case of OND and OND modes, it is able to set 0 since no min. setting time is applied.)

It may cause malfunction if above instructions are not followed.
