10.5.9 Impulse operation in one direction /
Permanent clearance in the other direction
When a permanent signal is only present on one of the two inputs
IN2 "opening impulse passage left" and IN3 "opening impulse
passage right", passage is cleared in the corresponding direction.
Impulse operation remains active in the other direction.
When the other direction is cleared in impulse operation, the
passage direction is locked at once in permanent clearance
operation. Only when the hold-open time has elapsed will the
passage direction be cleared again in permanent clearance
operation.
If a permanent clearance signal is applied during impulse
operation, the stored opening pulses for this passage direction are
deleted.
The end position lock is not activated in permanent clearance
operation in one direction.
10.6 Special cases during 120° operation
10.6.1 Stopping in mid-movement
If the blocking element is stopped in mid-movement, e.g. from the
user not moving on, the motor will continue to turn at minimum
torque. At the same time, the alarm output is activated.
10.6.2 Turning back in mid-movement
If there is an attempt to turn back the blocking element in the
wrong direction during passage, the locking is activated at once.
10.6.3 Turning contrary to the released direction
If a user turns the blocking element in the wrong direction from
standstill after release, the locking is activated at once. After a
pause the brake will be released and the misalignment of the arm
adjusted.
10.6.4 Adaptive speed adjustment
The rotary lock is equipped with two speed levels. A pass starts
when a person moves the blocking element by more than 15°. The
rotating speed of the blocking element is measured during these
15°. At a rotating speed of more than 2 rad/s, the control works
with increased running parameters. At a rotating speed of 2 rad/s
or less, the control works with standard parameters.
