CAUTIONS FOR SAFE USE
[Power supply]
Use the power equipment with overtemperature
protection and circuit breakers. We recommend
HAKKO POWER BOX 15B .
[Relay]
DG2N controls temperature by ON/OFF of a
contact relay. The more frequent ON/OFF
cycles are, the shorter the lifetime of the relay
is. According to the manufacturer, the lifetime
of the relay will end in 200,000 cycles of ON/
OFF. If 200,000 cycles are reached, the power
indicator starts blinking quickly. Then stop the
use of DG2N and replace it, otherwise it may
cause fires or serious accidents. If you prefer
static relays, use HAKKO DIGITAL FINE
THERMO DG2P/DG3P. For frequent use,
overtemperature protectors are needed.
[Use only for heaters]
DG2N is only designed for heaters. Do not use
as a controller for such as electric lights,
motors, or electromagnetic contactors.
[Current load]
Current load of heaters is 15A or less to
connect. When you need to apply the heater
with more than 15A, use HAKKO THERMO
series, CH controllers, or HP controllers.
[Noise]
Strong noise may cause malfunctions. Set
DG2N away from the source of noise or replace
the power equipment when the noise arises.
[Vibration]
DG2N has no vibration proof structure. Use in
the condition without vibration.
[Use in equipment]
If you use DG2N-100V successively as built-in
apparatus in the equipment, detach the plug of
cable and connect on the terminal block firmly.
Periodic inspections (every 6 months or one
year) are needed. Overheat or deformation may
cause fire.
[Fire protection]
Pay fully attention to the protection from firing
and electric shock when you use DG2N and
heaters.

1. FOR SAFE USE OF THIS PRODUCT
We use the following symbols for safety.
WARNING
Improper use may cause the danger of death or injury.
CAUTION
Improper use may cause the danger of slight injury or property
damage.
WARNING
● Connect power cables with
the controller by crimping
terminals.
CAUTION
● Power off and connect
sensors or wire cables.
● Do not use the controller
outdoors.
DG2N is designed only for indoor use.
● Do not use other power voltage
than the indicated.
Otherwise it may cause fire and electric
shock.
● Do not sink the sensor sleeve or
compensation lead wires into
water.
Otherwise it may cause failures.
● Do not operate the controller
with wet hands.
Otherwise it may cause electric
shock.
● Do not use other than recommend-
ed sensors.
Otherwise, it may cause fire, electric
shock or failures.
Otherwise it may cause fire or electric shock.
● Do not pour water at the
controller.
Wet controller may cause electric
shock or leakage.
● Do not bent or pull forcedly, or
deform the power cables.
Otherwise it may cause fire or electric
shock. Ask your distributor to replace
when the power cable has damage.
Otherwise it may cause electric shock.
● Hold the plug by hand and pull out
of the socket.
Damage on cables may cause fire
and electric shock.
● Do not use longer than the relay's
lifetime.
Otherwise it may cause fire. The lifetime
of the relay is 200,000 cycles of ON/OFF.
･ Power indicator starts blinking quickly after 200,000
cycles are reached.
Otherwise it may cause explosion or
fire.
● Do not use in the explosive
or flammable atmosphere.
● Do not use the heater in the
following condition. It may
cause fire, electric shock
or failures.
･Use in the corrosive atmosphere
･Use in the atmosphere at temperatures of -5℃ or less
･Use in the atmosphere at temperatures of 40℃ or more
･Use in the atmosphere of high humidity, such as bath
･Use in the steamy or water dropping place
● Do not alter or deform the control-
ler.
Otherwise it may cause fire, electric
shock and failures.

Power ON/OFF
DG2N has no power switch on the body. After powered
on by plugging or a breaker, the temperature indicator
shows
and some numbers from to .
Consequently current temperature is indicated. Power
off immediately after use of DG2N.
Temperature setting
① Normally the temperature indicator shows current
temperature.
② After pressing buttons once (0.3 second), the
temperature indicator shows target temperature for 1
second. After 2 or 3 seconds, it returned to show current
temperature.
③ To raise the target temperature, press the upper button.
To turn down, press the lower button. One press
(0.3second) can change one degree. Keeping pressing
can make continuous change.
④ Keep pressing to approach the target temperature,
and press some more times to adjust to it (the range
of setting temperatures is from 0℃ to 750℃). 2 or 3
seconds after releasing from button, the indicator
shows current temperature.
Reconfirmation of the target temperature
If you need to see target temperature while heating,
press either the upper or the bottom button once (0.3
second) and the indicator shows target temperature. If
you press again within 3 seconds, the target
temperature moves. Press once after 5 seconds if you
need to confirm again.
