Run-On Encoder; Stop Function During Disengagement Angle; Reverse; Reverse Delay - DAAB EP104 Instruction Manual

INSTRUCTION MANUAL DAAB AUTOMATIC CONTROLL UNIT EP104 4.08

• Run-on encoder

See the "Stop function" section under "Run-on time" below. When an encoder is used, the run-on times in C422, C423, C432 or
C433 are not used. The EP104 instead calculates an angle that is displayed in L114, L115, L124 and L125. If this angle is too small,
that is to say the door/gate stops too quickly, the run-on can be increased by configuring a value in F114, F115, F124 or F125.
To disable photocell, safety edge and load guard before closed position, an angle is specified in channels L117 and L127. To
disable vehicle loops before closed position, an angle is specified in channels L118 and L128. The channels are set to the
number of degrees where disengagement is to apply, counting from the angle of closed position in L113 and L123. This angle
is known as the disengagement angle.
!
Choosing disengagement angles that are too large may lead to a crush risk.

Stop function during disengagement angle

Select channel C436 and choose the stop function you want during disengagement angle. The function specified in channel
C436 is only active during the disengagement angle for closing. Depending on the stop function configured in C436, you
can set the door to close tightly against rubber strips without triggering the load guard or safety edge.
NOTE! Channel C436 is subordinate to channel C448, safety edge reverse during the run-on time, see "Safety edge".
There are four options for the stop function during disengagement angle in closing movement – channel C436 0, 1, 2 or 3,
provided reverse during disengagement angle is disabled in channel C448.

• Reverse

Reverse delay

To obtain faster or slower turning in change of direction, the time when the door changes direction can be adjusted.
Use channel C492 to configure the reverse delay – either opening or closing – after the photocell or a vehicle loop is
activated.
Select channel C492 and set a suitable delay. Note that when a frequency converter has been selected in C202, channel C492
is not displayed, and the times specified in F005 and F006 instead apply to retardation.

Reverse priority

The automatic control unit is normally set to priority open, channel C063 = 1, which means that opening continues to the
fully open position even if the close button is pressed while the door is opening.
Important. The change of priority does not apply to the open/stop/close or open/close function in programmable inputs.
• Priority open only
When the open button is pressed during closing, the direction changes to opening.
When the close button is pressed during opening, nothing happens.
Select channel C063 and set the value to 1.
• Priority close only
When the close button is pressed during opening, the direction changes to closing.
When the open button is pressed during closing, nothing happens.
Select channel C063 and set the value to 2.
• Priority open and close
When the open button is pressed during closing, the direction changes to opening.
When the close button is pressed during opening, the direction changes to closing.
Select channel C063 and set the value to 3.
• No priority
Pressing the open or close button has no effect if the door is already moving.
Select channel C063 and set the value to 0.

Functions using add-in cards

Add-in cards can be installed in the EP104 for access to extra functions. DB407and DB410 programmable outputs, DB402
vehicle detector, DB411 (the DBR1 system) for 4 programmable radio inputs, DB408 for interlock communication, and
DB409 for motor control with frequency converter.
Follow the instruction manual supplied with the add-in card when installing add-in cards in the EP104 and commissioning.
