■ Basic Operation Setting of Selector The selectors can be turned clockwise and counterclockwise to select the desired time scale, or operating mode. Each selector has a snap mechanism that secures the selector at a given position. Set the selector at a position at which it is secured. Do not set it midway between two securing positions or a malfunction could result from improper setting.
■ Timing Chart Note: 1. The minimum power reset time is 0.1 s and the minimum signal input time is 0.05 s. 2. The letter “t” in the timing charts stands for the set time and “t–a” means that the period is less than the time set. 3. There is no start input for H3DS-SL@/-AL@ models. Operation starts at power-on.

Installation of Screw-Less Clamp Models Timers ■ Tools A flat-blade screwdriver should be used to mount the cables. Applicable Screwdriver ● Flat-blade, Parallel-tip, 2.5 mm diameter • Flat-blade, Parallel-tip 2.5 dia. • Flat-blade, Flared-tip Cannot be used. Examples: FACOM AEF.2.5 × 75E VESSEL No. 9900-(-)2.5 × 75 WAGO 210-119 WIHA 260/2.5 × 40 ■ Applicable Wires Applicable Wire Sizes 0.2 to 1.
■ Wiring ■ Precautions Use wires of the applicable sizes specified above. The length of the exposed conductor should be 6 to 7 mm. Always insert the screwdriver straight into the hole, never at an angle. The clamp spring may be deformed if the screwdriver is not straight. 6 to 7 mm Fig. 1 Exposed Conductor Length Use the following wiring procedure. 1. Insert the specified screwdriver into the release hole located beside the wire connection hole where the wire is to be inserted.

Precautions ■ Changing of Setting ■ Power Supplies The H3DS Series is provided with a transformerless power supply system. An electric shock may be received if the input terminal is touched while power is being supplied. Use the bar terminal for wiring the H3DS. Using a stranded-wire terminal may cause a short-circuit due to a stray wire entering into the Timer. Both AC and DC power supplies can be connected to the power input terminals without regarding polarity.
The H3DS as a built-in timer conforms to EN61812-1 provided that the following conditions are satisfied: Contact or transistor for external input signal A1 Incorrect ■ Precautions for EN61812-1 Conformance B1 H3DS-ML@ Power supply The output section of the H3DS is provided only with basic isolation. To ensure reinforced isolation required by the EN61812-1, provide supplementary basic isolation on the load side connected to the output.
