Mode Setting
GT3A only
The operation mode can be selected from A, B, C, and D modes
using the Operation Mode Selector. The operation mode is changed
from A to B, C, and D in turn by turning the Operation Mode Selector
clockwise using a flat screwdriver 4 mm wide maximum and the se-
lected mode is displayed in the window. Since this selector does not
turn infinitely, turn the selector clockwise when Mode A is displayed
and counterclockwise when Mode D is displayed.

Time Range Setting
The time range is calibrated at its maximum time scale, therefore,
it is desirable to use the timer at a setting as close to its maximum
time scale as possible for accurate time delay. For a more accurate
time delay, adjust the setting knob by measuring the operating time
before application.
1. GT3A (Multi-Mode Analog Setting Type)
Time range can be selected from 1S, 10S, 10M, and 10H by turning
the Time Range Selector with a flat screwdriver 4 mm wide maxi-
mum. The four different ranges of 0 to 1, 0 to 3, 0 to 6, and 0 to
18 are displayed in the six windows by turning the Dial Selector,
allowing for selecting the best suited scale. Since the selectors do
not turn infinitely, turn the selectors clockwise when 1S or 0-1 is dis-
played and counterclockwise when 10H or 0-18 is displayed.
•
The set time is selected by turning the setting knob.

2. GT3F (OFF Delay Type)
The time range of GT3F-1 and GT3F-2 can be selected between 1S
and 10S with the Time Range Selector by using a flat screw driver.
The selected time range (0-1, 0-3, 0-18, or 0-60) is displayed in the
six windows of the Setting Knob by turning Dial Selector which al-
lows to set the scale. Note that the switches do not turn infinitely.

The set time is selected by turning the Setting Knob.

Range
When the setting knob is set at 2.5, with dial 0-3 and range 1S
selected, then the set time is 2.5 sec (2.5
When the setting knob is set at 15, with dial 0-18 and range 10S
selected, then the set time is 150 sec (15
Be sure to use wires to meet voltage and current requirements
and tighten M3.5 terminal screws to a torque of 1.0 to 1.3 N•m. Be
sure to solder the terminals correctly. Loose terminal screws or
incomplete soldering may cause abnormal heat and fire.
Time Range Determined by Time Range Selector and
Dial Selector
When the setting knob is set at 1.5, with dial 0-3 and time range
10S selected, then the set time is 15 sec (1.5
When the setting knob is set at 0.2, with dial 0-1 and time range
10H selected, then the set time is 2 hours (0.2
