Operating Procedures ■ Basic Operation Setting the Time Ranges Setting the Time ● Setting the Time Ranges ● Setting the Time The scale multiplier can be changed with the timer range switch. It can be changed between ×0.1 s and ×1 s for an S-series Timer and between ×1 s and ×10 s for an L-series Timer.
H3DK Safety Precautions ● Refer to Safety Precautions for All Timers. Note: The following is common for all H3DK models. Caution Switching arcs or relay heating may cause fire or explosion. Do not use the Timer in the presence of inflammable or explosive gases. The H3DK Series uses a transformerless power supply system. An electrical shock may occur if an input terminal is touched while power is being supplied.
H3DK Precautions for Correct Use ● Changing Switch Settings Do not change the time unit, time scale, operating mode, or INIT/ TIME switch while the Timer is in operation. Doing so may result in malfunction. Turn OFF the power supply before changing the setting of any switch. ● Mounting and Dismounting • Although there are no particular mounting restrictions, the Timer should be mounted as horizontally as possible.
H3DK ● Wiring The H3DK-H acts like a high-impedance circuit. Therefore, the Timer may not reset if it is influenced by inductive voltage. To eliminate inductive voltage, the wires connected to the Timer must be as short as possible and should not be installed parallel to power lines. If the Timer is influenced by inductive voltage that is 30% or more of the rated voltage, connect a CR filter with a capacitance of approximately 0.
