Timers
These timers require a start input. A gate and reset input are optional. Inputs are controlled by external pushbuttons. Reset occurs when the power is removed or
when the reset input is supplied. The gate signal can be used to interrupt (freeze) timer functions. Timer functions resume when the gate input is removed. B style
timers are not equipped for gate input.

Mode Selector
1. Use the flat screwdriver to set the selectors.
Since selectors do not turn all the way around,
both clockwise and counterclockwise rotation
may be necessary.
2. The Indicator Mode Selector determines
whether the Digital Time Display shows the
time elapsed or time remaining. The Opera-
tion Mode Selector determines the desired
operation mode. Decide which display and
mode is desired, then use these two selec-
torsto set the operation mode.
3. The Operation Mode Selector has two
blank modes which are not intended for use.
Always have this selector set to A, B, C, or D.

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.
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; con-
nect 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 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 voltage.

2. Since changing the setting during timer oper-
ation my cause malfunction, turn power off
before changing.
Safety Precautions
Special expertise is required to use Electronic Timers.
All Electronic Timer modules are manufactured under IDEC's rig-
orous 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.
• Install the Electronic Timer according to instructions described in
this catalog.
• Make sure that the operating conditions are as described in the
specifications. If you are uncertain about the specifications, contact
IDEC in advance.
• In these directions, safety precautions are categorized in order of
importance to Warning and Caution.
Warning
Warning notices are used to emphasize that improper operation may
cause sever personal injury or death.
• Turn power off to the Electronic timer before starting installation,
removal, Wiring, maintenance, and inspection on the Electronic
Timer.
• Failure to turn po wer off may cause electrical shocks or fire hazard.
• Emergency stop and interlocking circuits must be configured out-
side the Electronic timer. If such a circuit is configured inside the
Electronic Timer, failure of the Electronic timer may cause mal-
function of the control system, or an accident.
Caution
Caution notices are used where inattention might cause personal
injury or damage to equipment.
• 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 speci-
fications. If the Electronic Timer is used in places where it will be
subjected to high-temperature, high-humidity, condensation, corro-
siv e gases, excessi ve vibrations, or excessi ve shocks, then electrical
shocks, fire hazard, or malfunction could result.
• Use an IEC60127-approved fuse and circuit breaker on the power
and output line outside the Electronic Timer.
• Do not disassemble, repair, or modify the Electronic Timer.
When disposing of the Electronic Timer, do so as industrial waste.

Inputs
To avoid electric shock, do not touch the input signal terminal during power voltage applica-
tion.
When connecting the input signal terminals of two or more GT3A timers to the same contact or
transistor, the input terminals of the same number should be connected. (Connect Terminals
No.2 in common.)
In a transistor circuit for controlling input signals, with its primary and secondary power cir-
cuits isolated, do not ground the secondary circuit.
Connect the input signal terminals of the GT3A timers to Terminal No.2 only. Never apply volt-
age 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.

Timers
For contact input, use highly reliable gold-plated contacts to make sure that the residual voltage is
less than 1V when the contacts are closed.
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 1k when the transis-
tor 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
Start Input The start input initiates a time-delay
operation and controls output status. No-voltage contact inputs and
NPN open collector transistor
inputs are applicable.
24V DC, 1mA maximum
Input response time:
50msec maximum
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).

Timers
Timing accuracies are calculated from the following formulas:
Repeat Error
Voltage Error
Tv: Average of measured values at voltage V
Tr: Average of measured values at the rated voltage
Temperature Error
Tt: Average of measured values at °C
T20: Average of measured values at 20°C
Setting Error

oad Current
W
ith inductive, capacitive, and incandescent lamp loads, inrush current more
t
han 10 times the rated current may cause welded contacts and other undes-
i
red effects. The inrush current and steady-state current must be taken into
c
onsideration when specifying a timer.
C
ontact Protection
S
witching an inductive load generates a counter-electromotive force (back
E
MF) in the coil. The back EMF will cause arcing, which may shorten the con-
t
act life and cause imperfect contact. Application of a protection circuit is
r
ecommended to safeguard the contacts.
T
emperature and Humidity
U
se the timer within the operating temperature and operating humidity
r
anges and prevent freezing or condensation. After the timer has been stored
b
elow its operating temperature, leave the timer at room temperature for a
s
ufficient period of time to allow it to return to operating temperatures before
u
se.
E
nvironment
A
void contact between the timer and sulfurous or ammonia gases, organic
s
olvents (alcohol, benzine, thinner, etc.), strong alkaline substances, or strong
a
cids. Do not use the timer in an environment where such substances are
p
revalent. Do not allow water to run or splash on the timer.
V
ibration and Shock
E
xcessive vibration or shocks can cause the output contacts to bounce, the timer
s
hould be used only within the operating extremes for vibration and shock resis-
t
ance. In applications with significant vibration or shock, use of hold down
s
prings or clips is recommended to secure a timer to its socket.
Time Setting
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 operat-
ing time with a watch before application.
Input Contacts
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 proxim-
ity switch, photoelectric switch, or solid-state relay), malfunction may be
caused by leakage current from the solid-state device. Since AC types com-
prise a capacitive load, the SSR dielectric strength should be two or more
times the power voltage when switching the timer power using an SSR.
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).
