Function 1
Interval timer - man. start -
no restart - man. time reset
The relay operates when in-
terconnecting pins 5 and 7.
When disconnecting pins 5
and 7, the time period starts.
At the end of set time period,
the relay releases. Intercon-
nection of pins 5 and 7 for at
least 10 ms during the time
period, causes the time to
reset. No restart when time
period has expired.
Function 2
Like function 1, but with man-
ual start.
Function 3
Interval timer - man. start -
man. restart - no time reset
The relay operates and the
time period starts when inter-
connecting pins 5 and 7 for at
least 10 ms. At the end of set
time period, the relay releases
regardless of the connection
between pins 5 and 7. Re-
newed connection between
pins 5 and 7 causes the relay
to operate and a new time pe-
riod starts.
Function 4
Delay on operate - man.
start - no restart -
man. time reset
The time period starts when
disconnecting pins 5 and 7.
At the end of the set time
period, the relay operates.
When interconnecting pins 5
and 7 for at least 10 ms du-
ring the time period, the time
is reset and a new time period
starts when pins 5 and 7 are
disconnected. No restart
when the time period has ex-
pired.
Function 5
Delay on operate - man.
start - man. restart - time
reset
Otherwise like function 4.
Function 6
Delay on operate - man.
start - man. restart - no time
reset
The time period starts when
connecting pins 5 and 7. At
the end of the set time period,
the relay operates. When con-
necting pins 5 and 7 after the
time period, the relay releases
and a new time period starts.

Function 7
Interval timer - aut. start -
no restart - man. time reset
The relay operates and the
time period starts when pow-
er supply is applied. At the
end of the set time period, the
relay releases. When intercon-
necting pins 5 and 7 for at
least 10 ms during the time
period, the time is reset and a
new time period starts when
pins 5 and 7 are disconnect-
ed.
No restart when the time peri-
od has expired.
Function 8
Like function 2, but with auto-
matic start after applying
power supply.
Function 9
Like function 3, but with auto-
matic start after applying
power supply.
Function 10
Delay on operate - aut. start
- no restart - man. time
reset
The time period starts when
power supply is applied. At
the end of the set time period,
the relay operates. When in-
terconnecting pins 5 and 7 for
at least 10 ms during the time
period, the time is reset and a
new time period starts when
pins 5 and 7 are dis-
connected.
No restart when the time peri-
od has expired.
Function 11
Like function 5, but with auto-
matic start after applying
power supply.
Function 12
Like function 6, but with auto-
matic start after applying
power supply.
