Time Setting

Mode of Operation

Function Op

Delay on operate

The time period begins as

soon as the trigger contact

is closed.

At the end of the set delay

time the relay operates and

does not release until the

trigger

contact

is

closed

again or the power supply is

disconnected. If the trigger

contact is closed before the

end of the delay time, the

device resets and a new

time period starts.

Function In

Interval

The relay operates and the

time period begins as soon

as the trigger contact is

closed. The relay releases at

the end of this period or

when the power supply is

disconnected.

The

relay

operates again when the trig-

ger contact is closed again. If

the trigger contact is closed

before the end of the delay

time, the device resets and a

new time period starts.

Function Io

Interval on trigger open

The relay operates and the

time period begins as soon

as the trigger contact is

opened. At the end of the

set delay or when the power

supply is disconnected the

relay

releases.

The

relay

operates again when the

trigger contact is opened

again. If the trigger contact

is opened before the end of

the delay time the relay

keeps ON and a new time

period begins.

Function Id

Double interval

The relay operates and the

time period begins as soon

as the trigger contact is

closed. The relay releases at

the end of this period or

when the power supply is

disconnected.

When the

trigger contact is opened

the relay operates again for

the set delay period. If the

trigger contact is opened

before the end of the first

time period the second one

begins; if the trigger contact

is closed before the end of

the second time period the

device resets and the first

time period begins again.

Function Dr

Delay on release

The relay operates as soon

as the trigger contact

is

closed.

The

time

period

begins when the trigger con-

tact is opened. The relay

releases at the end of the

set delay time or when the

power supply is disconnect-

ed. The relay operates again

when the input contact is

closed again. If it is opened

before the end of the delay

time the relay keeps ON, a

new time period begins as

soon

as

the

contact

is

closed again.
