Universal Slider Action Solenoid S.1
V2.1 –HW rev. 15 –SW rev. 1.7
The S.1 magnet sets the benchmark for the most advanced generation of slider solenoids. It uses four
optical sensors for measuring the motion speed of the slider. The automatic force adjustment feature sets
the perfect speed assuring that the magnet comes to a soft and silent stop at the end position. The
control circuitry readjusts the force in case of load changes so that the slider moves at optimum speed
and reaches the exact end position without fail.
Wiring:
The S.1 magnet is compatible with most standard controllers. The polarity of the control signal
can be changed by a solder bridge on the circuit board.
Positive input (standard)
Negative input
The magnet can be controlled by way of a continuous RS signal (stop switch) which is applied as
long as the stop is engaged, or by way of pulsed ON-OFF signals generated by some capture
systems.

Set-Up
Setting the upper current limit
After magnet cabling, set the upper current limit as required by the expected force (see overview,
feature 2). Standard setting is level 1. Level 1 corresponds to a force of approx. 45 N at a current of 1.4 A
(24 V), the standard round slider action solenoid (cat.no. 3 010 30).
Level 4 provides approx. 65 N, which is similar to the standard rectangular magnets (cat.no. 3 010 60).
On this level, the magnet can draw a current of up to 3 A. In extreme cases, up to 105 N can be supplied
at a current of 6 A.
The automatic force regulation automatically increases the current in case of a higher mechanical slider
resistance without, however, exceeding the preset limit. This limitation prevents any power supply
overload. The upper current limit should be set in such a way as to allow the organ power supply to
switch all magnets simultaneously. The power limit should be increased exclusively for those sliders
which sometimes need more force than the others.
Higher speed settings (see feature 6) may also require a higher current limit.
Teaching the required force
Once the magnet has been installed and wired, use the TEACH function to initialize the teaching process
(see feature 1).
In TEACH mode, the slider is moved back and forth until the correct working force parameter is set.
The LED chain indicates the currently required force in relation to the preset maximum current. If the
indicator is already at the upper end of the scale, there may not be sufficient resources available for the
compensation of a later sluggishness. In such a case, check the mechanical slider action and increase
the current limit if indicated (this measure requires a new TEACH process).
Error indicators
If the slider has too much friction, the LED 8 lights up permanently (see functions 8, 9). If the Error-LED
start flashing as well, the slider is either blocked completely or some of the optical sensors are defective.
In this case, please check if the slider can be moved by hand and initiate a new teaching cycle. If the
Error-LED continue to flash, please check the sensors using the diagnostics function 7.

Operating Modes and Functions
Feature 0: RUN
This is the standard operating mode. For testing, press the set button to move the magnet to the opposite
position.
LEDs no.1 to 8 indicate the currently required force:
- LED 1 force < 60%
- LED 2 force > 60%
- LED 3 force > 70%
- LED 4 force > 75%
- LED 5 force > 80%
- LED 6 force > 85%
- LED 7 force > 90%
- LED 8 force > 95%
When the magnet moves towards ON, the force required for ON is displayed. When it moves towards
OFF, the display outputs the necessary OFF force.
A large difference between the respective forces usually indicates a mechanical slider problem. In that
case, check the movability of the respective slider.
Feature 1: TEACH
Teach process:
1. Switch the rotary switch to position “1”
2. LED 5 starts flashing
3. Press the set button to initiate the teach process
4. The magnet moves back and forth. LEDs show the required force (see feature 0)
4a - the teach process is finished when the force indicator starts flashing.
4b - the indicators show a running light moving from LED 1 to LED 8 if the slider motion is too
sluggish or the maximum force is too low (see feature 2)
5. Return the rotary switch to position “0”
The teach process can be stopped and started any time by pressing the set button.
Feature 2: LIMIT / MAX. CURRENT
The maximum admissible current is set with the set button.

Attention: Please note that a higher force always requires a higher current. This may overload the
power supply or organ rectifier. Prior to any force increase make sure that the organ power supply can
provide the current as needed for all magnets.

IP = Initial Positioning (for dual action)
The standard modes (with initial positioning) position the sliders upon activation. If, for example, the organ
is switched on with the stop switch engaged, the slider is moved to ON position irrespective of its current
position
The modes without initial positioning function do not position the sliders upon activation. If, for example,
the organ is switched on with disengaged stop switch and a slider is in ON position, the slider remains
where it is.
Should you discover after mounting the magnets, that the sliders operate in the oposite direction, it is very
easy to invert the operating direction of the slider magnet.
LED 8 off normal direction of movement (on / off as indicated on the control board)
LED 8 on inverted direction of movement
When the direction is inverted, the magnet moves to the indicated OFF-position when the control signal is
activated.

Feature 4: MODE (B)
Here, you can activate modes with holding force in different positions.

The holding force serves for holding, for example, mechanical couplers. In the holding position, a current
of 1A is applied to the magnet coil. The force cannot be adjusted.
If coupler assemblies return to their rest position by gravity, choosing damped decay may be useful. In
these modes, the S.1 will ramp down the holding current gradually to make the coupler return more softly.
Feature 5: RS OUT MODE
The slider action solenoid has several sensors for slider position detection. RS signal output can thus be
varied.

Feature 6: SPEED
Switch position 6 allows for the adjustment of the slider motion speed in 8 levels.
Standard speed setting is level 3. On this level, the operating noise is kept at a minimum. The S.1 magnet
runs at reduced speed to avoid the typical thump during slider switching. It comes to a smooth stop at its
end position and so enables an almost noiseless stop action.
This behavior may result in a movement which some customers perceive as sluggish, especially when
dual action is operated. If a faster response is desired, raise the speed settings. The higher the speed,
however, the louder the action sound because the accelerated mass of slider and magnet anchor cannot
be braked as effectively before the end position is reached.

Attention: Remember that a higher speed also increases the magnets’ current consumption. Especially
the highest levels 6 to 8 can dramatically increase power consumption, e.g. from 2 A on level 3 to 4 A on
level 8.
Feature 7: DIAGNOSTICS
The diagnostics function allows testing of the light barrier, input, button and RS output functions.

LED 2 track sensor OFF
LED 3 track sensor ON
LED 4 end position sensor ON
LED 5 button
LED 6 ON (RS) input
LED 7 OFF input
LED 8 RS output
Feature 8: ERROR RESET
The S.1 saves error conditions and indicates them with LED 8 or the flashing Error-LED. This feature
allows fast and easy detection of even transient problems.
To delete the error messages saved to the system, simply press the RESET button.
The saved errors are also deleted when the TEACH process is started.
Feature 9: ERRORS
When the switch is this position, the LEDs indicate the nature of the problem:
LED 1 blockage in ON direction
LED 2 blockage in OFF direction
LED 3 maximum force moving to ON
LED 4 maximum force moving to OFF
