6. Self-diagnosis function
If a malfunction occurs, one of the following displays will appear.
Note 1: When the counter value goes below the minimum value during any of the subtraction, directive, independent, or phase input modes.
Note 2: Includes the possibility that the EEPROM’s life has expired.
7. CE Marking Certification
1) EMC directive (89/336/EEC)
As a counter unit, the LC4H series con-
forms to EMC directives. Applicable
standards are EN50081-2 and EN50082-
2.
2) Low voltage directive (73/23/EEC)
In order to satisfy VDE0435/Part 2021,
be sure to adhere to the following instal-
lation conditions and precautions.
(1) The counter uses a non-transformer
power supply and the power supply and
input signal terminals are not insulated.

input circuit, install double insulation on
the sensor side.
• With contact-point inputting, use dou-
ble-insulated relays, etc.
(2) Always connect loads insulated with
basic insulation specifications to the out-
put contact points. The counter unit is
also insulated with basic insulation speci-
fications. The combination of the two sat-
isfies VDE, which calls for double insula-
tion.
(3) For the applied power supply, use
one protected by an over-current protec-

tion device that conforms with EN/IEC
standards (e.g. 250 V, 1 A fuse).
(4) During installation, always use a ter-
minal block or the appropriate sockets.
Do not touch the terminals, or other part
of the counter unit while it is on. Before
installation or removal of the unit, first
verify that no voltage is being applied to
any of the terminals.
(5) Do not use the counter in a safety cir-
cuit. When the unit is being used in a cir-
cuit such as a heater circuit, install a pro-
tection circuit on the machine side.
