the actuator has reached its retracted end
position or the external limit switch signal is
on.
LED green:
LED is on steady if the actuator is in its
selected stroke range. The LED is off if the
actuator has reached its extended end
position.
LED red:
LED is on steady if the motor over
temperature switch is open or not connected.
The LED is flashing if the rotating motor
axis has an offset to one side or another.
If all LED’s are flashing in the rotating order
yellow, green, red the printed circuit board is
not mounted properly. As a result the
distance between the magnet on the rotating
shaft may be too large or too small or not
pointing to the center of the sensor. The
mounting of the printed circuit board should
be checked. Without proper mechanical
adjustment the board is not operational,
therefore, a reliable function of the limit
switches can not be guaranteed.
Further LED display patterns are described
in the below manual setup procedure.
Manual Setup Procedure
The EPS 02 limit switch function can be
configured via the two onboard push buttons.
This is only necessary during startup or
maintenance of the actuator if end of stroke
limits have to be changed or if changes to the
working condition, mounting position or
operational changes have to be made.
In general the push buttons have fixed
functions.
Push button S1 is used to advance from one
function to the next.
Push button S2 is used to select the value in
each of the selected function.
There are two settings which can be made
independent from each other:
1)
Setting of the end of stroke
position
in
the
retracted
position and
2)
Setting of the end of stroke
position in the extended
position
Please find below the manual set up
procedure to adjust the retracted and
extended end of stroke position.
Note: The EPS 02 comes factory preset
with the maximum stroke length and a
safety limit on both sides. As well the
actuator dependant settings for clock
wise or counter clock wise operation,
and the activation of the external limit
switch function.
To activate the manual setup mode both
push buttons S1 & S2 have to be
simultaneously pushed down for more
than 8 seconds. To acknowledge
entering the manual setup mode all three
LED’s will flash at the same time.
Release both push buttons at the same
time and the yellow LED will remain
flashing and the green and red LED will
turn off. You are now in mode 1.
Mode 1
Adjustment retracted position:
Note for units with external limit switch:
As mentioned before, do not make any
adjustments in mode 1 if the unit is
configured for an external limit switch.
Always start out with the desired
retracted position since this is your
reference point for the setting of the
stroke length.
If no adjustment to the retracted position
is required, go to the section “Change to
Mode 2”.
If adjustments are required the actuator
should be jogged to the desired retracted
position. To store the value of that
position hold down the push button S2
for 0.5 to 1 seconds.
