The GT3F, consisting of a high-impedance circuit, may not be reset due to the influence of an inductive voltage or residual voltage caused by a leakage current. If not
reset, connect an RC filter or bleeder resistor between power terminals so that the voltage between power terminals can be reduced to less than 15% of the rated

2. Since changing the setting during timer operation my cause malfunction,
turn power off before changing.
Special expertise is required to use Electronic Timers.
Caution
• All Electronic Timer modules are manufactured under IDEC’s rigorous quality
control system, but users must add a backup or fail safe provision to the
control system when using the Electronic Timer in applications where heavy
damage or personal injury may occur should the Electronic Timer fail.
Caution notices are used where inattention might cause personal injury or damage to equipment.
• Install the Electronic Timer according to instructions described in this catalog.
• In these directions, safety precautions are categorized in order of importance
to Warning and Caution.
• The Electronic Timer is designed for installation in equipment. Do not install
the Electronic Timer outside equipment.
• Install the Electronic Timer in environments described in the specifications. If
the Electronic Timer is used in places where it will be subjected to high-temperature, high-humidity, condensation, corrosive gases, excessive vibrations,
or excessive shocks, then electrical shocks, fire hazard, or malfunction could
result.
Timers
• Make sure that the operating conditions are as described in the specifications. If you are uncertain about the specifications, contact IDEC in advance.

Instructions: Setting GT3W Timer
• Use an IEC60127-approved fuse and circuit breaker on the power and output
line outside the Electronic Timer.
Warning
Warning notices are used to emphasize that improper operation may cause sever
personal injury or death.
• Do not disassemble, repair, or modify the Electronic Timer.
• When disposing of the Electronic Timer, do so as industrial waste.
Contactors
• Turn power off to the Electronic timer before starting installation, removal,
Wiring, maintenance, and inspection on the Electronic Timer.
• Failure to turn power off may cause electrical shocks or fire hazard.
• Emergency stop and interlocking circuits must be configured outside the
Electronic timer. If such a circuit is configured inside the Electronic Timer,
failure of the Electronic timer may cause malfunction of the control system, or
an accident.

For transistor input, use transistors with the following specifications; VCE = 40V, VCES = 1V or less, IC = 50 mA or more, and ICBO = 50µA or less. The resistance
should be less than 1kΩ when the transistor is on. When the output transistor switches on, a signal is input to the timer.

Inputs: GT3A-1, -2, -3
Transistor output equipment such as proximity switches and photoelectric switches can input signals if they are voltage/current output type, with power voltage
ranges from 18 to 30V and have1V. When the signal voltage switches from H to L, a signal is input to the timer

Inputs: GT3A-4, -5, -6
The start input initiates a time-delay operation and controls
output status.
Reset Input
When the reset input is activated, the time is reset, and
contacts return to original state.
Gate Input
The time-delay operation is suspended while the gate input
is on (pause).
No-voltage contact inputs and NPN open collector transistor inputs are applicable.

General Instructions for All Timer Series
Load Current
Vibration and Shock
With inductive, capacitive, and incandescent lamp loads, inrush current more
than 10 times the rated current may cause welded contacts and other undesired
effects. The inrush current and steady-state current must be taken into consideration when specifying a timer.
Excessive vibration or shocks can cause the output contacts to bounce, the
timer should be used only within the operating extremes for vibration and shock
resistance. In applications with significant vibration or shock, use of hold down
springs or clips is recommended to secure a timer to its socket.
Contact Protection
Time Setting
Switching an inductive load generates a counter-electromotive force (back EMF)
in the coil. The back EMF will cause arcing, which may shorten the contact life
and cause imperfect contact. Application of a protection circuit is recommended
to safeguard the contacts.
The time range is calibrated at its maximum time scale; so it is desirable to use
the timer at a setting as close to its maximum time scale as possible. For a more
accurate time delay, adjust the control knob by measuring the operating time
with a watch before application.
Temperature and Humidity
Input Contacts
Use the timer within the operating temperature and operating humidity ranges
and prevent freezing or condensation. After the timer has been stored below
its operating temperature, leave the timer at room temperature for a sufficient
period of time to allow it to return to operating temperatures before use.
Use mechanical contact switch or relay to supply power to the timer. When
driving the timer with a solid-state output device (such as a two-wire proximity
switch, photoelectric switch, or solid-state relay), malfunction may be caused by
leakage current from the solid-state device. Since AC types comprise a capacitive load, the SSR dielectric strength should be two or more times the power
voltage when switching the timer power using an SSR.
Environment
Avoid contact between the timer and sulfurous or ammonia gases, organic solvents (alcohol, benzine, thinner, etc.), strong alkaline substances, or strong acids.
Do not use the timer in an environment where such substances are prevalent. Do
not allow water to run or splash on the timer.

General Instructions
Generally, it is desirable to use mechanical contacts whenever possible to apply
power to a timer or its signal inputs. When using solid state devices, be cautious
of inrushes and back-EMF that may exceed the ratings on such devices. Some
timers are specially designed so that signal inputs switch at a lower voltage
than is used to power the timer (models designated as “B” type).
Timing Accuracy Formulas
Contactors
Timing accuracies are calculated from the following formulas:
Repeat Error
= ± 1 x Maximum Measured Value – Minimum Measured Value x 100%
2 Maximum Scale Value
Voltage Error
= ± Tv - Tr x 100%
Tr
Tv: Average of measured values at voltage V
Tr: Average of measured values at the rated voltage
Temperature Error
= ± Tt - T20 x 100%
T20
Setting Error
= ± Average of Measured Values - Set Value x 100%

Tt: Average of measured values at °C
