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

doesn’t

release until the power sup-

ply is disconnected.

The trigger contact is invalid

while the timer is in opera-

tion.

Function Rb

Symmetrical recycler

(OFF first)

The time period begins as

soon as the input contact is

closed. The relay is OFF

during the set delay period,

after this time it operates for

the same time period. This

sequence

continues

with

equal OFF- and ON- time

periods until power supply is

interrupted.

Function R

Symmetrical recycler

(ON first)

The relay operates and the

time period begins as soon

as

the

input

contact

is

closed. After the set delay

period the relay releases for

the same time period. This

sequence

continues

with

equal ON- and OFF- time

periods until power supply is

interrupted.

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

relay keeps ON 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 conctact 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.

Function In

Inteval

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

trigger

contact

is

closed

again. If the trigger conctact

is closed before the end of

the delay time, the device

resets and a new time peri-

od starts.

Function Io

Inteval on trigger open

The relay operates and the

time period begins as soon

as the trigger contact is

opened. The relay releases

at the end of this period or

when the power supply is

disconnected.

The

relay

operates again when the

trigger contact is opened

again. If the trigger conctact

is opened before the end of

the delay time, the device

resets and a new time peri-

od starts.
