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.
