H3DE
An interval of 3 s minimum is required to turn on the H3DE after the
H3DE is turned off. If the H3DE is turned on and off repeatedly with
an interval of shorter than 3 s, the internal parts of the H3DE may
deteriorate and the H3DE may malfunction.
If it is required that the output be turned on repeatedly with an inter-
val of shorter than 3 s, consider use of the H3DE-M2/-M1 in mode D
(signal OFF-delay).
The H3DE as a built-in timer conforms to VDE 0435/P2021 provided
that the following conditions are satisfied:
The output section of the H3DE is provided only with basic isolation.
To ensure reinforced isolation required by the VDE standards, pro-
vide supplementary basic isolation on the load side connected to
the output.
The H3DE itself is designed according to the following:
On the above basis:
Operation parts on the front and bottom: Reinforced isolation
– With clearance of 5.5 mm and creepage distance of 5.5 mm at
Output: Basic isolation
– With clearance of 3 mm and creepage distance of 3 mm at
When using the Timer in an area with excess electronic noise, sepa-
rate the Timer, wiring, and the equipment which generates the input
signals as far as possible from the noise sources. It is also recom-
mended to shield the input signal wiring to prevent electronic inter-
ference.
Organic solvents (such as paint thinner), as well as very acidic or
basic solutions can damage the outer casing of the Timer.
Do not use the Timer in places where it is exposed to dust, corrosive
gas, or direct sunlight.
When storing the Timer, make sure that the ambient temperature
and humidity are within the rated values. Leave the Timer at room
temperature for at least three hours before using the Timer if it has
been stored at an ambient temperature of –10 C or below.
If the Timer is mounted on a control board, dismount the Timer from
the control board or short-circuit the circuitry of the power board be-
fore carrying out a voltage withstand test between the electric cir-
cuitry and non current-carrying metal part of the Timer, in order to
prevent the internal circuitry of the Timer from damage.
It must be noted that although the electrical life expectancy of the
H3DE Timer shown in the catalog is the same as the H3DR Timer
shown in the catalog, the actual performance varies because the
built-in relays are different as follows:
Built-in relay for the H3DR: G2R; 100,000 operations min.
Built-in relay for the H3DE: G6RN; 50,000 operations min.
