Aut. start - man. restart
The relay operates and the
time period starts when power
supply is applied. At the end
of the set time period, the
relay releases. When inter-
connecting pins 5 and 7 after
expiration of the time period,
the relay operates and a new
time period starts.
Aut. start - man. restart
and time reset
The relay operates and the
time period starts when power
supply is applied. At the end
of the set time period, the
relay releases. When inter-
connecting pins 5 and 7 for at
least 10 ms during the time
period, the time is reset. When
interconnecting pins 5 and 7
after expiration of the time
period, the relay operates and
a new time period starts when
pins 5 and 7 are disconnected.
Man. start and restart
The relay operates and the
time period starts when pins
5 and 7 are interconnected for
at least 10 ms. At the end of
the set time period, the relay
releases regardless of the
interconnection between pins
5 and 7. Renewed connection
between pins 5 and 7 will
cause the relay to operate
and a new time period will
start.
Man. start - man. restart
and time reset
The relay operates when pins
5 and 7 are interconnected.
The time period starts when
pins 5 and 7 are discon-
nected. At the end of the set
time period, the relay re-
leases. When interconnect-
ing pins 5 and 7 for at least 10
ms during the time period, the
time is reset.
