6) Long periods of continuous operation
in the time-up completed condition (one
month or more) will result in the weaken-
ing of the internal electrical components
from the generated heat and, therefore,
should be avoided. If you do plan to use
the unit for such continuous operation,
use in conjunction with a relay as shown
in the circuit in the diagram below.
7. Self-diagnosis function
If a malfunction occurs, one of the following displays will appear.

7. Acquisition of CE marking
Please abide by the conditions below
when using in applications that comply
with EN61812-1.
1) Overvoltage category III,
pollution level 2
2) This timer employs a power supply
without a transformer, so the power and
input signal terminals are not insulated.
(1) When a sensor is connected to the
input circuit, install double insulation on
the sensor side.
(2) In the case of contact input, use dual-
insulated relays, etc.
3) The load connected to the output con-
tact should have basic insulation.
This timer is protected with basic insula-
tion and can be double-insulated to meet
EN/IEC requirements by using basic
insulation on the load.
PRECAUTIONS IN USING THE LT4H SERIES
Output condition
OFF
Enter reset input, RESET
key, or restart unit.
Restoration procedure
4) Please use a power supply that is pro-
tected by an overcurrent protection
device which complies with the EN/IEC
standard (example: 250 V 1 A fuse, etc.).
5) You must use a terminal socket or
socket for the installation. Do not touch
the terminals or other parts of the timer
when it is powered. When installing or
un-installing, make sure that no voltage
is being applied to any of the terminals.
6) Do not use this timer as a safety cir-
cuit. For example when using a timer in a
heater circuit, etc., provide a protection
circuit on the machine side.
