User manual
General
Left-right device is used to inverse rotating
direction of 2 ways rotating machine used in
industry. This device with time adjustment, repeats
its functions according to specified periods.
Utilization and Operation Principles
When the line voltage is applied, the right output
relay starts to work as switching ON and the
left output relay as switching OFF. At the end
of t
1
time both of two output relays switch OFF
and this condition is kept for t
0
times. At the
end of this. period, the left output relay switches
OFF and the right output relay switches ON
and also this situation is kept during t
1
time.

General
EF type flasher devices are developed due to
create adjustable periodic impulses. They are
produced in two different ways:
EF-10 : Flasher device with Relay output
EF-10T : Flasher device with Triac output
Connection Diagram
Function Diagram
General
The EF-2X device with adjustable ton and toff
times is developed in order to create periodic
impulses.

Function Diagram
General
If the supply is OFF less than 6* sec. output of
the device doesnt change.
Connection Diagram Function Diagram
When the supply is applied, output relay turns
ON and while supply exists output relay keeps
energized. When the supply is cut off, output
relay stays energized during adjusted t
1
time
(0.1-6 sec). At the end of that time, output relay
turns OFF. If the supply is applied before t
1
time
isnt up, output relay continues to stay energized.

Function Diagram
General
High quality digital timers used for safe operation
of star-delta starter systems. When the operating
voltage is applied, the star contacts
[(1/16, 2/15) for PK21/PK15, for PK25], are closed
and then released after the operating time, t
A
.
The delta contacts [(2/15, 3/18) for PK21/PK15]
are closed after the transition time, t
0
= 50 msec
(fixed at factory). The fault of the transition time
is
±
5 msec.
This transition time can be adjusted (to= 20-500
msec.) in PK25 type.
