Power supply

(See

note)

Power supply

Use

the same power source for the power sup

ply

and reset input and wire

the circuit so that the

terminals (1) and (10) terminals (2) and (9) be-

come the same phase respectively.

Reset

Note: The

R2 relay can be set

to either instantaneous or time-limit contact using the switch located on the bottom of the T

imer (H3AM-NS

models).

H3AM H3AM

Precautions

Before Use

Before using the H3AM-NSR, apply voltage between terminals 9

and

10 to reset the operation.

When

changing the setting time of the H3AM-NSR to a longer time

value,

be sure to apply voltage between terminals 9 and 10

during

the

change, otherwise the T

imer may malfunction.

Correct Use

Setting

Changes

sure to

adjust the time unit selector and instantaneous or time-

limit

output selector for R2 relay only before the T

imer is turned ON,

otherwise

the T

imer may be damaged or malfunction.

sure

to set the time only when T

imer has stopped, otherwise the

Timer

may malfunction.

Power Supply

Use

a switch or relay contact to impose supply voltage on the T

imer

at one time. If the supply voltage

imposed on the T

imer gradually

the

imer may not reset or a time-up error may result.

ime Setting

not turn the time setting knob beyond the permissible range. If

precise

time setting is required, check the operation of the T

imer in

trial

operation before the T

imer is put in actual operation.

Operating Environment

the T

imer is used in any place that may be af

fected by noise, be

sure

to separate the T

imer

, input device, and connecting wires from

the

noise source. The use of shielded wires for the input line is rec

ommended.

The

external surfaces of the T

imer may be af

fected by organic sol

vents

such as thinner

, benzine, or a strong alkaline or strong acidic

substance.

not use the T

imer in a location where the T

imer is exposed to cor

rosive

gas or direct sunlight or where there is excessive dust.

ater Protection

When

mounting the T

imer on a panel, evenly tighten the T

imer to

specified torque. If the T

imer using waterproof packing is tightened

a torque other than the specified value,

required waterproof prop

erties

will not be achieved.

Others

the T

imer is mounted on a control panel, dismount the T

imer from

the control panel or short-circuit the circuitry before carrying out a

voltage withstand test between the electric circuitry and non cur-

rent-carrying

metal part

of the machine, in order to prevent the inter

nal

circuitry of the TImer from damage.

The

internal elements may be damaged if a voltage other than the

rated

supply voltage is applied.

Precautions for VDE Conformance

The

H3AM as a built-in timer conforms to VDE0435/P2021 provided

that

the following conditions are satisfied:

The

output section of the H3AM is provided only with basic

isolation.

ensure reinforced

isolation required by the VDE standards, pro

vide supplementary basic isolation on the load side connected to

the

output.

The H3AM itself is designed according to the following:

•Overvoltage category III

•

Pollution degree 2

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

240

Output: Basic isolation

With

clearance of 3.0 mm and creepage distance of 3.0 mm at

240 V
