INSTRUCTION MANUAL DAAB AUTOMATIC CONTROL UNIT EP105

Revision 3
• 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 in channels L312 and L322 that is 20% longer than the readout time.
• 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 of motor protection
Read the current consumption of each motor during hold-to-run operation in 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. A
typical value for a drive unit of type MK with motor size 0.37 kW is 0.8 A. A typical value for MT with motor size 0.25 kW
is 0.4 A.
A set value of 0.0 does not mean that the internal protection for the motor is disabled and intended to be used for external
connectors.
When a frequency inverter is used, the instructions in the user manual for the DB409 must be followed.
The illustrations show motor protection settings for motor 1.

• 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 3x400 V+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 drive unit 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.
