EEL-S2-2
The S2-2 controller provides advanced positioning and control of actuators through easy and flexible integration with the application. The controller is designed to work with Bansbach easyE-line actuators in applications where positioning is required. S2-2 has adjustable start and stop ramps, which make smooth starts and stops possible.
Adjustable current limits in both directions protect the motor against overcurrent. In learning mode the number of hall pulses in a full stroke of the actuator is counted which enables accurate positioning during normal operation.
The position of the actuator is controlled by a DC voltage between 0-5 or 0-10 Volts to the S2-2.
Adjustments and parameter settings like current limit value, ramp times, speed etc. are set with S2-PROG interface unit or S2-USB “dongle” connected to a PC.

- If S2-2 goes into “trip” (overcurrent) it is only possible to run actuator in opposite direction.
- Please adjust the max. current to be 10% higher than maximum current during load.
- This ensures the longest actuator lifetime.
- Please ensure that the power supply for the controller is capable of supplying sufficient
- current – otherwise the controller and the actuator may be damaged.
- Doublecheck correct polarity of power supply. If connected wrong the S2-2 will be damaged.
- Attention! S2-2 has no fuse in it. Use external fuse according to application ( 2 -> 10A slow).

10–35 VDC (Use fuse)
Digital output 5V through 1kO when wanted position is reached and low during travel. Note: If “stop ramp” is very long, then POSITION OK signal can be difficult to reach, since the motor only gets very low power to reach within the “dead zone”
Digital input (>4V and max supply voltage starts “learning”. Rin 47kO
Digital input (>4V and max supply voltage) Stops the motor and resets any fault. Rin 47kO
NPN open collector max 100mA can be connected to other S2-2 modules, thereby all modules connected will stop if one module sends a FAULT signal. If wire length is more than 1 meter, a 10kO pull-up resistor connected to supply is recommended. Diagram in FIG 2
WIRING AND SETTINGS
First run the learning cycle and then do the settings with serial interface unit “S2-PROG” or PC.
Default values in ( )
1/15 Speed: 35 – 100% <=> 35-100 (100)
Speed limits the maximum speed.
2/15 Learning speed: 35 – 100% <=> 35-100 (50)
Learning speed sets the learning cycle speed. (FIG. 4)
3/15 I-limit “forward”: 0,1 – 20,0A <=> 1-200 (20)
I-limits are individual for reverse and forward directions.
Notice! Current limits are 1.5 times higher during start ramp and 1 sec. thereafter
4/15 I-limit “reverse”: 0,1 – 20,0A <=> 1-200 (20)
I-limits are individual for reverse and forward directions.
Notice! Current limits are 1.5 times higher during start ramp and 1 sec. thereafter
5/15 I-trip enable: 0/1 <=> off/on ( 1 )
I-trip enables the trip function, so that motor will be shut down when the set I-limit is exceeded. Motor has to be started in opposite direction after trip.
6/15 I-trip delay: 0 – 255ms <=> 0 – 255 (5)
I-trip delay defines the reaction time for trip.
7/15 Load compensation: 0 -255 <=> 0 – 255 (0)
Load compensation increases the torque at low speed. Note that over-compensation will cause oscillation and twiching of the motor.
8/15 Pulse lost timeout: 1 – 5s <=> 1 – 5 ( 2 )
Pulse lost timeout stops motor after the set time without pulses.
9/15 Start value: 0 – 50% <=> 0 – 50 ( 30 )
Start value is a voltage level for start (% of full), this ensures that the motor gets an adequate voltage to start properly, but note that too high start level will cause motor vibration (FIG. 3).
10/15 Hour/Start count reset: 0 – 1, reset when set to 1
Hour/Start count reset makes possible to set the hour/start counter to zero.
11/15 Stop ramp: 0,0 – 20,0% <=> 0 – 200 (50)
Stop ramp is proportional value of the full stroke. In low speed application good value is near 1%, and in high speed solution it can be near to 20% (FIG. 3).
12/15 Dead zone: 0,0 – 10,0% <=> 0 – 100 (10)
Dead zone is steady area, suitable size of this zone depends on the mechanical accuracy of the system, this value is also a ratio of the full stroke (%) (FIG. 3).
13/15 Range scale in: + 0,0 – 50,0% <=> 0 – 500 ( 7 )
Dead zone is steady area, suitable size of this zone depends on the mechanical accuracy of the system, this value is also a ratio of the full stroke (%) (FIG. 3).
14/15 Range scale out: – 0,0 – 50,0% <=> 0 – 500 (70)
Range scale adjustment is for scaling of the stroke, with this the scale can be adjusted after learning. The reverse and forward ends are individually scaleable to get the suitable mechanical stroke for set value from 0-10V (0-5V) (FIG. 5).
15/15 Start ramp: 0,1 – 5s <=> 0 – 500 ( 100 )
Start ramp (soft-start) defines the time before reaching full speed.
stroke the pulse counter measures the range.
stroke the pulse counter measures the range.
If range scale in = +20% and
range scale out = -20%.
now stroke of actuator is compressed to:
positioning set value 0V = 20% position
positioning set value 10V (5V) = 80% position
