7.2 Setting of the hold-open time (trimmer P1)

• It effects the automatic closing travel of the door after expiry of this
time from the upper end position or the intermediate holding position.
• The hold-open time is activated by the switching of the DIP2 switch
into the ON position.
• It can lie within the range of 1s to approx. 320s. The setting range is
illustrated in the bottom of the Figure.
• An active emergency stop input or a stop command deactivates the
hold-open time.
• The hold-open time only runs out after release of all open commands
and security devices.
• The hold-open time is deactivated with three closing travel attempts
take place one after the other, wherein the security strip has been actuated.
