Instructions: Wiring Inputs for GT3 Series
Inputs
To avoid electric shock, do not touch the input signal terminal during power voltage application.
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 con-
nected. (Connect Terminals No.2 in common.)

General Instructions Timers

General Instructions for All Timer Series
Load Current
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 consider-
ation when specifying a timer.
Contact Protection
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.
Temperature and Humidity
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.
Environment
Avoid contact between the timer and sulfurous or ammonia gases, organic sol-
vents (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.
Vibration and Shock
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.
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 operating 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 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 capaci-
tive 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).
Timing Accuracy Formulas
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
Tt: Average of measured values at °C
T20: Average of measured values at 20°C
Setting Error = ± Average of Measured Values - Set Value x 100%
Maximum Scale Value
