If a previously stored value for the retract
position does not allow you to jog to the new
desired retracted position, hold down the
push button S2 for longer than one second.
The retracted limit switch function is now
disabled. Pay close attention to the physical
end limits of the actuator and as well the
attached equipment.
To store the value of that position hold down
the push button S2 for 0.5 to 1 second.
Change to Mode 2
Press push button S1 for 0.5 to 1 second. The
LED pattern will change to a flashing green
LED and the yellow LED will turn off.
Mode 2
Adjustment extended position:
If no adjustment to the extended position is
required go to the section “Change to
Operating Mode”.
If adjustments are required the actuator
should be jogged to the desired extended
position. To store the value of that position
hold down the push button S2 for 0.5 to 1
seconds.
If a previously stored value for the extended
position does not allow you to jog to the new
desired extended position, hold down the
push button S2 for longer than one second.
The extended limit switch function is now
disabled. Pay close attention to the physical
end limits of the actuator and as well the
attached equipment.
To store the value of that position hold down
the push button S2 for 0.5 to 1 second.
Operating Mode
Hold down the push button S1 for 0.5 to 1
second. The LED pattern will change to its
normal operational condition. See above
“LED Display” section.

TTL Level Communication Interface
The EPS02 is equipped with a TTL
level communication interface. To
connect the unit to a standard RS232
interface or USB interface, a signal
converter
is
required.
It
is
recommended, especially in harsh and
noisy environments, to use a galvanic
isolated converter to protect the RS232
serial or USB port of your laptop or
computer from transient voltage spikes
or other magnetic fields which can be
introduced into the connection cable. In
modest environmental conditions a
straight through TTL to USB can be
used. The 10 pin square post connector
as well as the 4 pole plug connector
provide the +5V to power up the
optically isolated side of the converter.
The other side of the converter will be
powered up by the RS232 or USB port
of the laptop or computer.
