INSTRUCTION MANUAL DAAB AUTOMATIC CONTROLL UNIT EP104 4.08

Instruction manual edition 1 for EP104 version 4.08
For a top-mounted motor winder, the motor is configured as for a right-mounted motor window. See below for the side-
mounted motor winder. Note that if the motor winder is installed upside down, the sides must be swapped because the
motor runs in the "wrong" direction.
• Connect the encoder according to the instructions on page 15, "Connecting an encoder".
• Specify channel L001 as 4, hold-to-run without limit switch, then specify location of motor 1 in channel L110 where 1
is left and 2 is right. Keep the factory setting for L002 at 0
• Run the motor (hold-to-run) to the closed position, then read channel L111 for motor 1 and specify the value as closed
position in channel L113 for motor 1. The value in L111 and L121 must always decrease when closing.
• Run the motor (hold-to-run) to the open position, then read channel L111 for motor 1 and specify the value as open
position in channel L112 for motor 1. The value in L111 and L121 must always increase when opening.
• If two drive units are used, L001 is set to 0 and L002 to 4, in order to be able to run motor 2 in hold-to-run without
limit switch. Then specify location of motor 2 in channel L120 where 1 is left and 2 is right.
• Run the motor (hold-to-run) to the closed position, then read channel L121 for motor 2 and specify the value as closed
position in channel L123 for motor 2.
• Run the motor (hold-to-run) to the open position, then read channel L121 for motor 2 and specify the value as open
position in channel L122 for motor 2.
• Then set both L001 and L002 to 1, encoder.
• Specify channel C033 as 0, hold-to-run with load guard inactive.
•
Check that both halves open and close to specified positions.
•
The limit switches are now configured and the motor will stop at the specified degrees. Note that some fine tuning may
be necessary depending on the type of door and if there is motor slippage.
Mechanical limit switches (microswitches)
If conventional mechanical limit switches are used, the unit is configured as follows.
• Set channel L001 to option 2 for mechanical limit switch.
• Set channel L002 to option 2 for mechanical limit switches if there are two motors.
• Adjust the limit switch cams so they match the open and closed positions of the door. The easiest way to do this is to
move the door to the end position and adjust the cam so that it activates the limit switch.
• Fine adjustment is possible using the run-on times in channels C422, C423, C432 and C433.
Timer control (without limit switches)
Motor winders without a limit switch can use timer control instead. With timer control, you measure the actual opening
time of the door and set the automatic control unit to operate the motors for that length of time. To configure the unit for
timer control, use the following channel settings.
• Set L001 to 3 for timer control.
• Set L002 to 3 for timer control if there are two motors.
• Run the motor (hold-to-run) to the fully closed position, then run the motor to the fully open position.
• Read channel L311 for motor 1 and make a note of the value.
• Read channel L321 for motor 2 (if there is one) and make a note of the value.
• Set a time that is 20% longer than the time in channel L312 for motor 1 and L322 for motor 2.
• Direction of rotation of motors
To reduce the risk of injury or damage, the door must be disconnected during commissioning.
Check that the motor is running in the right direction by pressing the open and close buttons on the automatic control unit.
If the direction of rotation is wrong, change the phase sequence of the motor, see "Connection – high current".
• Setting the internal motor protection
Read the current consumption of each motor during hold-to-run operation – from channel C251 for motor 1 and C261 for
motor 2 – then set the motor current in channels C252 and C253 for motor 1 and channels C262 and C263 for motor 2.
The typical value of the MK operator with a motor size of 0,37kW is 0,8A. For MT with motor size 0,25kW, the type value
is 0,4A. The value 0.0 means that the motor protection is switched off, this setting is used if external contactors are used.
When a frequency converter are used, the instructions in the DB409 manual should be used.
• Type of power supply
Only change this setting in high current installations with no neutral or a single-phase power supply.
The actual supply voltage is specified in channel C202.
The factory setting is 0, which means a supply voltage of N+PE. For other options, see the channel reference.
Checking the phase sequence for 3x230 V without neutral
If there is no neutral, the load guard takes two phases as reference points, so the phase sequence must be correct.
To check that the phase sequence is correct, decouple the motor winder to allow the motor to run without load. With the
motor running, read the value in channel C271 for motor 1 and C281 for motor 2 – the value should be about 0.20. If the
phase sequence is incorrect, the value is about 0.95 and the load guard is activated.
See "Connection – high current" to find out how to correct an incorrect phase sequence.
