Ordering Information

■ Basic Setting

Setting of Selector

The selectors can be turned clockwise and counterclockwise to 

select the desired time unit, time range, output type (only for H3BAN8H) 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.

Selection of Operating Mode with H3BA-N Turn the operating mode selector with a screwdriver until the desired operating mode (A, B, B2, C, D, E, G, or J) appears in the display window located above the selector. Selection of Output Type with H3BA-N8H Turn the output type selector with a screwdriver until the desired output type (A or H) appears in the display window located above the selector. Selection of Time Unit and Time Range The desired time unit (sec, 10 s, min, 10 m, hrs, or 10 h) is displayed in the window below the time setting knob by turning the time unit selector located at the lower right corner of the front panel. A time range (1.2, 3, 12, or 30) is selected with the time range selector at the lower left corner of the front panel, and the selected time range appears (in the window at the lower right part) within the plastic frame of the time setting knob.

■ Using the Setting Ring

Setting a Specific Time

Mount the Panel Cover on the Timer, set the desired time with the 

time setting knob, and place Time Setting Ring A onto the time 

setting knob so that the time setting notch of Time Setting Ring A is 

in the center of the reset lock position of the Panel Cover.

Limiting the Setting Range

Example: To set a range of 10 and 20 s.

Mount the Panel Cover on the Timer, set the time setting knob to 10 s 

(the lower limit of the setting range), and place Time Setting Ring C 

onto the time setting knob so that the stopper of Time Setting Ring C 

is on the right edge of the reset lock position of the Panel cover. Next, 

set the time setting knob to 20 s (the upper limit of the setting range), 

place Time Setting Ring B onto the time setting knob so that the 

stopper of Time Setting Ring B is on the left edge of the reset lock 

position of the Panel Cover.
