DAAB EP104 Instruction Manual page 20

Commissioning
The process is the same for EP104-1 for one motor winder and EP104-2 for two motor winders.
The settings are changed as described in the section "Changing settings in the EP104".
An E on the far left of the display indicates an error message, see "Error messages". Note that the start-up values "EP-1" and
"EP-2" are not error messages.
Carry out the commissioning steps in the order shown – this will ensure that the channels are configured in the correct
sequence.
The automatic control unit is supplied in hold-to-run mode. Hold-to-run means that the motor runs while the button is
pressed, and stops when it is released.
The control unit will only work correctly if the following steps are carried out:
• Safety
Anyone commissioning the EP104 must have documented familiarity with, and understanding of its functions, as well
!
as experience of commissioning control systems for the application to be used.
See "Settings" to find out how to read and configure values in the EP104.
!
Check that:
• All equipment is mechanically secured and installed according to the applicable instruction manuals.
• All components are correctly connected and installed by authorised installers before switching on the power supply.
• The necessary safety measures are in place to remove the risk of crushing and other risks relating to the controlled unit.
• Any necessary decoupling devices are installed in the controlled unit and that they work as intended.
Make sure you:
• Discharge any static charge in your body by touching an earthed object, for example the earth connection between the door
and the control unit, before changing settings or doing other work on the EP104.
• Take care when operating internal buttons to avoid touching live components.
• Stop circuit
The stop circuit consists of a safety output, stop buttons and contactors. If the control unit detects a fault during the self test,
the power to the contractors is interrupted. The stop buttons are connected in series with the contactors, and they interrupt
the power to the contactors. Check that the stop diode lights up.
• Limit switch
Limit switches are used to inform the unit when the door is in the open or closed position. There are three limit switch options
to choose from: Encoders, which are electronic limit switches that detect the exact position of the door in degrees; mechanical
limit switches using cams that control microswitches; or, if the motor does not have any physical limit switches, timer control.
Encoder (electronic limit switch)
Left encoder position
The encoder works by detecting the position of the door, and acts as an intelligent limit switch. A magnetic proximity sensor
means that the EP104 knows the precise position of the door, and the limits for the open and closed positions can be
directly configured in the unit using degrees, rather
than physically changing the limit switch cams in the motor winder. It is possible to commission one motor at a time by
activating only one limit switch at a time (L001, L002).
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 that the encoder is used for motor 1 by setting L001 to 1, specify the position of motor 1 in channel L110
– 1 is left and 2 is right.
• If two motor winders are used, activate the encoder for motor 2 in channel L002 by setting it to 1, specify the
position of motor 2 in channel L120 – 1 is left and 2 is right.
• After setting the encoder position and activating it, run the motor (hold-to-run) to the closed position, then read
channel L111 for motor 1 and make a note of the value. If two motor winders are used, also read channel L121
