Bansbach Easylift S4 Series User manual

Controller EEL-S4
The Bansbach S4 series is a range of battery-based actuator controllers developed especially for mobile
applications. The controller can manage up to 4 actuators with a wired handset and it is supplied by
either a NiMH Li-Ion-battery.
The controller may be configured using PC software which may be ordered separately from Bansbach.
This allows patterns of operation, stroke length, speed, etc. for the connected actuators to be adjusted.
EEL-S4
Battery Based Actuator Control System
Preparation
Before the system may be used, the battery must be charged using the accom-
panying charger. It takes 5-8 hours to fully charge a battery.
The yellow LED lights up when the charger is connected to power. Place the
battery in the charger by sliding it in and rotating it until it is pulled into place by
the magnets. The green LED will flash at approx. 1 second intervals while the
battery is being charged. Once charging is complete the green LED remains
permanently lit. Remove the battery by rotating it 90 degrees. It will then be
ejected and be ready for use.
Once the battery is fully charged, insert it into the controller. Follow the same
procedure as for the charger. If everything is OK, the controller will simply sound a beep (one second)
once the battery is in place. If the system has any faults, the beep will be followed by an error indication
according to table 1 below.
When the battery requires recharging, transfer it to the charger as described above. It is recommended
that you keep an extra battery on hand to avoid disruption to operation.
Always wait at least two seconds after the last actuator has stopped moving before removing the battery.
Otherwise the controller may not have time to store the position and it may be necessary to perform
0-point calibration as described in section „Normal operation“.

What is the EEL-S4?
MANUAL

Normal operation
During normal operation the actuator is driven in an out using the appropriate buttons on the remote control.
Situations may arise which require a particular action. These situations are described below.
1. Low battery level
If the battery level goes below a warning level while operating the actuators, three short buzzer tones are
sounded. This means that the battery requires recharging, and the actuators can therefore only be driven in
one direction (normally in).
2. Flat battery
If the battery level goes below a minimum level while operating the actuators, one short buzzer tone is soun-
ded. The actuators will stop immediately and the controller will shut down. The battery must be charged. You
must wait at least one minute before inserting a new battery into the controller. If you are using actuators with
position feedback (hall effect), you will need to perform 0-point calibration. See below.
3. Extreme battery load
The battery may become too hot if it is subject to extreme load due to repeated operations in rapid successi-
on, thereby activating the battery‘s safety thermostat. The controller will shut down and the battery must be
allowed to cool for at least half an hour before being used again. You must wait at least one minute before
inserting a different battery into the controller. If you are using actuators with position feedback (hall effect),
you will need to perform 0-point calibration. See below.
4. 0-point calibration
If you use actuators with position feedback (hall effect), you will need to perform 0-point calibration on the
controller so that the innermost position of the actuators can be recorded. This must be done for all actuators
which use position feedback. The controller will sound two short buzzer tones following the beep when the
battery is inserted if 0-point calibration is required.
It is also possible to initiate manual 0-point calibration by holding in the relevant ‘in’ buttons for 10 seconds.
The controller sounds a beep followed by 2 long buzzer tones and 0-point calibration can be performed by
pressing the ‘in’ button and holding it so that the given actuator(s) is/are driven in. Hold down the button until
the actuators have been driven fully in. The controller has now been 0-point calibrated and the system may
be used normally. The actuators can only be driven in during 0-point calibration.

Troubleshooting
If problems or irregularities arise you should go through the points below (in consultation with a
technician where appropriate).
Check that all connectors are correctly attached to the controller.
Check that the controller sounds a beep when the battery is inserted.
If the actuators cannot be operated, perform a 0-point calibration as explained in section
If none of the above resolves the problem, please contact the supplier.

Tips:
It is recommended that you follow the tips below to achieve the best results and avoid problems in daily
operation.
1. General:
Always wait at least two seconds after the last actuator has stopped before removing the battery from
the controller. Otherwise controllers using position feedback may not have time to store the position, and
the controller will have to be 0-point calibrated again.
If the battery‘s safety thermostat is activated due to overload, the battery must be allowed to cool for at
least half an hour before being used again. A new battery may be inserted into the controller after one
minute.
If two or more actuators which operate in parallel become misaligned, the controller will automatically
shut them down. It will then be necessary to perform 0-point calibration again as described in section
„Normal operation“.
2. Batteries:
Always use batteries which are in good condition and fully charged when inserted into the controller.
You can extend the lifetime of the battery by occasionally recharging it even though it is not fully dischar-
ged.
If the battery level drops below the critical level and the system shuts down, you must wait at least one
minute before inserting a different battery and using the system again.
If the system is not to be used for an extended period (several days or weeks), the battery should be
removed from the controller to avoid deep discharge, which can cause lasting damage to it.
3. Handling:
Avoid getting metal shavings or other magnetic objects on the battery poles or in the controller.
