C (y1) : Command
• H function:
Timing on energisation -
Pulse output (adjustable)
1 relay
On energisation, the output relay
"R" (or the load) changes state, and
stays there for the whole duration of
the time delay and drops out at the
end of the single shot cycle.
• Ht function:
Delay on energisation with memory
1 relay
Adds up the total opening time
of a contact.
On energisation, the output relay
"R" (or the load)
changes state, and stays there for
the whole duration of the time delay
and drops out at the end of the
single shot cycle.
• K function:
Delay on de-energisation
True delay off
(without auxiliary power supply)
1 relay
On energisation, the output relay
"R" (or the load) changes state.
On de-energisation timing starts
and the relay "R" will only drop out
at the end of this time delay.
• L function:
Asymmetrical flashing
1 relay
Repetitive cycle with two times
which can be set independently.
Each time delay alternates with a
different state of the output relay
"R" (or the load).
Note: The cycle starts with
the relay
"
R
"
in the rest position.
2 timers or
2 relays including
1 instantaneous
• Li function:
Asymmetrical flashing
1 relay
Repetitive cycle with two times
which can be set independently.
• N function:
"Safe-guard"
On the first control pulse,
the output is excited.
If the interval between two
impulses is longer than the timing
value, this occurs normally and the
output relay "R" (or the load)
will change state at the end of
timing. Otherwise, relay "R" stays
in its original state until the
condition is fulfilled.
• O function:
"Delayed safe-guard"
On energisation, a first timer
runs and the output relay "R"
(or the load) changes state.
On the appearance of a control
pulse, relay "R" returns to its initial
position and stays there as long as
the time interval between 2 impulses is less than the timing value.
Otherwise, relay "R" will change state at the end of timing.
• P and Pe functions:
Impulse counter (delay on)
P function:
Timing starts on energisation.
At the end of timing, the output
relay "R" (or the load) changes
state for approximately 500 ms.
Pe function:
On energisation.
At the end of timing, the output
relay "R" (or the load) changes
state for approximately 1 s.
• Pt function:
Impulse counter (delay on)
Adds up the total opening time
of a contact.
At the end of timing, the output is
excited for approximately 500 ms.
• Q function:
"Star-delta" starting
On energisation, the "star"
contact closes instantaneously
and timing starts.
At the end of timing the Ti "star"
contact opens. After a pause
of 40 to 100 ms the "delta" contact
closes.
• TL function:
Impulse relay
After energisation, a control pulse
or latching contact closes the
relay. A second control pulse
opens the relay.
• Tt function:
Timed impulse relay
After energisation, a control pulse
or latching contact closes the relay
and starts timing.
The relay opens at the end of timing
or on a second control pulse.
• W function:
Timing after pulse on control contact
After energisation, opening of the
control contact results in a change
in the state of output "R" (or the
load) and timing starting.
