Functional description for control unit ED520
1 ED520 General
The door controller is intended for use with sliding or sectional doors with electrical drive, electronic limit
switches and motor speed control encoder. The basic module ED400/500 is fitted with the function board
ED520 for control with automatic functions and that is the new control unit ED520. ED520 is with electronic
limit switches and motor speed control encoder and furthermore ED520 still have all the same features as
ED420 control unit. In connection with control unit ED520 it is furthermore possible to expand with traffic light
and radio remote control. The functions of the door control are designed to ensure the highest possible degree
of comfort while being in accordance with the current safety demands.
1.1 Safety precautions
Installation and maintenance of the controller should only be done by qualified personal.
Disconnect the power prior to any work or maintenance at the controller or any related installations.
Installation, operation and maintenance of the controller, should be done in accordance to any local
directives related to power operated doors. When operating the door in Hold To Run mode, the person
controlling the door shall be instructed in use of the controller, and shall be in full view of the door and
the vicinity of the door during the leaf movement, and not be in a hazardous position himself.
By neglecting the safety precautions, you are responsible for any damage it may cause to
persons or goods!
1.2 Supply disconnection
In order to disconnect the electrical supply to the controller, the controller shall be connected to the
electrical supply with a main switch or a plug that disconnect the complete electrical supply to the
controller.
2 ED520 Normal operation
By turning on the controller for the first time, the display DP1 will show [ ], then the version number of the
program and then [0] again. Then the control unit has to be adjusted by making a run-in sequence paragraph
6.8. After this the control unit is ready for operation. Now the LED’s LD1, LD2 and the display DP1 will indicate
present operation mode, as described in paragraph 7 dealing with indications.
The controller is now ready for operation.
The following describes the automatic functions obtained with ED520 function board.
Open By activation of the input UP [ S5 ] the door will open from any given position until
top limit value (0) is reached, or to any programmed extra opening height.
By activation of the input UP [ S5 ] during closing of the door, the door will stop and
reverse to open position.
Close By activation of the input DOWN [ S6 ] the door will close from any given stopped
position, until the bottom limit value is reached.
Stop/emergency stop By activation of the input STOP [ S4 ] (emergency stop) the door stops at all times.
Reactivation can then only be done after deactivation of the STOP [ S4 ] input and
subsequent activation of the required function. By activation of the stop button on
the control unit, the door will stop at all times. The desired function can subsequent
be selected.
½-open By activation of the input/change-over ½-UP [ S14 ] it is possible to open the door
from a closed position to a programmed height with the UP [ S5 ] or the pull switch
input. If the door has been opened to a programmed height, an additional push on
the UP [ S5 ] button will open the door completely. The opening height can be
adjusted by programming within the limits of the opening height, however not less

than 3 seconds.
Setting of programmable opening height appears from part 6.4
Pull switch The door will open until open position from any given stopped position, when the
input PULL [ S10 ] is activated.
When activating the input PULL [ S10 ] while the door is in open position, the
closing function is started.
When activating the input PULL [ S10 ] during opening or closing function, the door
stops. The function of the pull switch can be changed as described in comfort
setting 1 and 2.
Extra This input is used in connection with extension for traffic light. The input EXTRA
[ S13 ] is used as an UP function from the outer side of the door. The traffic light
indicates by red/green lamp from which side the door can be entered.
Alternatively the input can be used to enable or disable of automatic closing. The
alternative function is selected under setting of functions. The function of the
EXTRA switch can be changed as described in comfort setting 3.
Top limit value By reaching the top limit value (0), the opening function is stopped.
Bottom limit value By reaching the bottom limit value, the closing function is stopped.
The controller expects activation of the pneumatic safety edge, when the bottom
limit value indicates door closed, and if necessary the controller will provoke two
short steps in order to obtain signal from the safety edge.
Pneumatic Safety edge By activating the input SE [ S7 ] during closing function, the door will stop
immediately, and then reverse to open position. If the safety edge is activated by
closing again, the subsequent closing function will take place in hold to run mode.
Photocell By activation of the input PHOTO [ S12 ] (door track mounted) during closing
function, the door will stop immediately, and then reverse or remain stopped as
selected during setting of safety functions.
By activation of the input PHOTO [ S12 ] during waiting for automatic closing, the
time for automatic closing is restarted after the input is activated.
The photocell (bracket mounted) can furthermore be selected to only reverse the
door leaf higher then an interval of 60 - 120cm during closing, fewer than that limit
the door leaf will stop.
During an opening sequence the door will stop fewer then the interval of 60 -
120cm and higher then that limit the door will ignore the signal from the photocells.
Automatic closing After the door is opened the measuring of time for automatic closing starts. After
expiration of the time, which is adjustable between 2 seconds and 30 minute, the
door starts closing automatically. Automatic closing can be left out as described
during setting of comfort function 4 and from part 6.1, and if convenient be disabled
and enabled by a switch connected to the input EXTRA [ S13 ]. When automatic
closing is enabled by input EXTRA [ S13 ] the door starts closing automatically.
Carwash function When this function is selected, the automatic closing will not start until the photocell
is passed by. Forced closing after a preset time can also be chosen, in case the
photocell is not passed by. The carwash function can be selected as described
under setting of comfort function 5, 6 and from part 6.2 and 6.3.
As carwash function is a part of automatic closing, this must be activated.

3 ED520 Deviation from normal operation
Opening The photocell can under safety settings also be selected to stop the door during an
opening sequence fewer then the interval 60 - 120cm and higher then that limit the
door control will ignore the signal from the photocells.
When the encoder operates as an anti-crushing device, the door will stop if the
speed differs with more than 4 % of the normal speed. That is if the door strikes an
obstacle during opening, the encoder will stop the door leaf movement. After the
door has been checked, the door can be operated again in auto mode by pushing
the up- or down-button.
Closing If the input SE [ S7 ] or the input PHOTO [ S12 ] is activated during the closing
process, the door will stop immediately and then reverse to open position. By
selection of safety functions, activation of the input PHOTO [ S12 ] may be set to
just stop the door.
The photocell can furthermore be selected to only reverse the door leaf higher then
an interval of 60 - 120cm during closing, fewer than that limit the door leaf will stop.
When the encoder operates as an anti-crushing device, the door will stop if the
speed differs with more than 4 % of the normal speed. That is if the door strikes an
obstacle during closing, the encoder will reverse the door leaf movement. After the
door has been checked, the door can be operated again by activation of the
selected function.
Stop/emergency stop By activation of the input STOP [ S4 ] (emergency stop) the door stops at all times.
Reactivation can then only be done after deactivation of the STOP [ S4 ] input and
subsequent activation of the required function. The input is integrated in the stop
circuit together with LOCK [ S3 ] and gear ON/OFF [ S2 ]. By activation of the stop
button on the control unit, the door will stop at all times. The desired function can
subsequent be selected.
Lock If the input LOCK [ S3 ] is activated, the door is stopped immediately. Re-start can
now only be done after deactivation of the LOCK [ S3 ] input, and subsequent
activation of the selected function. The input is integrated in the stop circuit
together with STOP [ S4 ] and gear ON/OFF [ S2 ].
Gear On/Off If the input gear On/Off [ S2 ] is activated, the door is stopped immediately. The
door controller will act as if there is a power failure and reestablishes automatically
the limit values when the switch is deactivated. The input is integrated in the stop
circuit together with STOP [ S4 ] and LOCK [ S3 ].
The input is normally used with the chain drive system of the door.
Normal hold to run mode If comfort setting 15.b is selected the door controller is functioning in normal hold to
run mode. Which is like normal operation, but with “hold to run” during close
operation and auto during opening mode.
(Normal hold-to-run mode: When up – auto mode. When down – hold-to-run mode)
4 ED520 Extension with radio remote control
The control unit can be extended with a radio module place in CON3 on the basic module ED400/500, which
makes it possible to operate the PULL [ S10 ] function. It is also possible to use a remote controlled 3-button
function, radio open door [ S30 ], radio stop door [ S31 ] and radio close door [ S32 ].
5 ED520 Extension with traffic light
The control unit can be extended with control of traffic light, which is connected to CON4 on the basis module
ED400/500. The traffic light indicates with red and green light from which side of the door driving through is

allowed. In this case the input EXTRA [ S13 ] is to be connected to the outside UP function.
6 ED520 Setting of comfort functions
Setting of the functions in the control unit is divided into setting of comfort functions and setting of safety
functions. In this way it is guaranteed that the safety functions of the control unit are not changed unintended.
Setting of safety functions are only possible with the programming key placed in connector CON3.
The comfort functions of the control unit are set by means of the two push buttons SW1 and SW2 on the
function board ED520, and the selected function is indicated on the display DP1 and also on the LED’s LD1
and LD2.
To gain access to the setting functions e-stop is to be activated, simultaneously with activation of the buttons
SW1 and SW2 for 5 seconds. The display will now flash to indicate that setting of comfort functions has been
selected, and afterwards the display will indicate the function about to be set according to the table below.
With SW1 the function number is selected. This is indicated on the display and the LED’s LD1 and LD2 show
the present settings. Each time the SW1 is pressed the function number is increased by 1. Setting of the
required function can be changed by pressing SW2. To save the selected adjustment SW2 has to be activated
for 3 seconds, after which the display briefly will show "S=" to confirm the saving the setting.
When the controller is in setting of functions mode, the door cannot be operated. The only exception is if a run-
in is mated, then the control unit is functional in hold to run mode.
The setting of functions is automatically terminated after 30 seconds without activation of SW1 or SW2 or
when turning off the control unit.

•After selection of the function, the display will indicate the present setting in seconds
•The factory settings for programmable opening height are 90 seconds or completely open,
depending on which condition will occur first
6.5 Behaviour at bottom position
The behaviour at bottom position is set under comfort function 9.
If comfort function 9-a is selected the door controller will provoke a short step in order to obtain a signal
from the safety edge. When the reversing point is reached the motor is deactivated and then activated
again to obtain a signal from the safety edge. That is done to make sure that the bottom seal is positive
and the wire is tight.
If comfort function 9-b is selected the door controller will close at bottom position without making at short
step. When the door leaf reaches the motor stop limit, the door controller stops the door leaf and
reaches the bottom limit position, by the continuing movement. The reversing point is automatically
loaded by the activation of the safety edge.
If the ground somehow has change position height because of ex. snow or dirt, the controller will
maximum provoke 2 short steps in order to obtain a signal from the safety edge. In case of a safety
edge error the control unit will indicate a failure 2 on the display and switch to hold to run mode.
6.6 Cycle counter
The cycle counter counts how many up-down sequences the door has accomplished. The cycle counter
counts only if the reversing point disconnected and safety edge is activated.
The cycle counter value can be viewed in the comfort settings 11-a.
After selection of the function, the display will indicate the first value 100000Th.
There can be shown 1Th, 10Th, 100Th, 1000Th, 10000Th, 100000Th.
With both green LD1 and red LD2 on will indicate that it is the first number (100000Th) and with only the
green LD1 on will indicate the middle values and with none LED’s on will indicate the last number (1Th ).
Next input is selected by pressing SW1 and previous input by pressing SW2.
When the cycle counter value is viewed, SW1 or SW 2 is activated for 3 seconds in order to exit the
function.

6.7 Latest failure
The 2 latest failure can be viewed in the comfort settings 12-a.
After selection of the function, the display will indicate the latest failure, by pressing SW1 the next failure
will occur. Decreased by pressing SW2 the first failure will be showed again.
When the failures are viewed, activate SW1 or SW2 for 3 seconds in order exit.
6.8 Run-in
When the control unit is powered up for the first time and/or the display is indicated a failure 0, the speed
control encoder must be run-in to make sure that the top and bottom values and average speed is
adjusted. That is done by following the sequence below.
•Turn on the power.
•The display will indicate a failure 0.
•Or choose comfort setting 13-a.
•Push the up button until top end position is reached (hold to run mode), be a wear that there are
no top limit switches.
