Mode of Operation
In connection with all func-
tions automatic start is pos-
sible by permanent intercon-
nection of pins 5 & 7.
Function 0: Delay on operate,
leading edge, man. start,
man. restart, man. time reset.
Function 1: Interval timer,
leading edge, man. start,
man. restart, man. time reset.
Function 2:
Symmetrical
recycler, OFF-time first, lea-
ding edge, man. start, man.
restart, no time reset.
Function 3:
Symmetrical
recycler, ON-time first, lea-
ding edge, man. start, man.
restart, no time reset.
Function 4: Delay on operate,
trailing edge, man. start, man.
restart, man. time reset.
Function 5: Interval timer,
trailing edge, man. start, man.
restart, man. time reset.
Note: The output relay only
operates when the time peri-
od is running.
Function 6: Interval timer,
trailing edge, man. start, man.
restart, man. time reset.
Function 7: Delay on operate,
leading edge, man. start,
man. restart, man. time reset.
Note: The relay releases on
trailing edge, which means
the trigger pulse must be of
longer duration than the time
period.
Function 8: Recycler with fix-
ed ON-time, leading edge,
man. start, man. restart, no
time reset. Fixed ON-time:
approx. 0.5 sec.
Function 9: Time period mul-
tiplier, leading edge, man.
start, man. restart, man. time
reset.
Note: Each pulse input adds
the set time the total timing
period. Max. time period
memory is 256 pulses.
Time stop function: By inter-
connection of pins 7 & 8 the
time function stops, and the
output relay remains either
released or operated. By dis-
connection of pins 7 & 8 the
remaining time continues to
elapse.
