1. An inrush current fl ows during the minimum power application time. AF20: approximate 0.4A,
AD24: approximate 1.2A
2. GT3F does not read the preset time range shown on the knob after power is turned off. Note that minimizing
the preset time, by turning the knob to zero, does not shorten the delay time after power is removed.

The set time is selected by turning the l Setting Knob.
1. When the Setting Knob l is set at 2.5, with Dial Selector j 0 to 3 and Time
Range Selector k 1S selected, then the set time is 2.5 seconds.
2. When the Setting Knob l is set at 5.0,
with Dial Selector j 0 to 60 and Time Range Selector k 10S selected, then the
set time is 500 seconds.

Instructions: Wiring Inputs
Inputs of GT3F
To avoid electric shock, do not touch the input signal terminal during power voltage application.
Never apply the input signals to two or more GT3F timers using the same contact or transistor.
[Incorrect]
Input
Contact or Transistor
Switches & Pilot LightsDisplay LightsRelays & SocketsTimersTerminal Blocks
In a transistor circuit for controlling input signals, with its primary and secondary power circuits isolated, do not ground the secondary circuit.
On the GT3F timers, connect the input signals to terminal No.1 and 4 only on the 8-pin type; connect the input signals to terminal No. 6 and 7 only on the 11-pin type.
Never apply voltage to other terminals; otherwise, the internal circuit may be damaged.

Input signal lines must be made as short as possible and installed away from power cables and power lines. Use shielded wires or a separate conduit for input wiring.
The GT3F, consisting of a high-impedance circuit, may not be reset due to the infl uence of an inductive voltage or residual voltage caused by a leakage current. If not
reset, connect an RC fi lter or bleeder resistor between power terminals so that the voltage between power terminals can be reduced to less than 15% of the rated
voltage.
