ACM 400 S motor control unit
8 / 24
Warning!
Do not connect the gate drive unit to the motor
, until you are convinced the motor
runs in the
correct rotational direction
– e.g. after electrical startup. Otherwise
there is a
risk of accidents
if the motor turns in an unexpected direction!
Gates without a mechanical end stop must be secured via a second "safety
limit switch" downstream of the normal limit switch,
if the gate causes a hazard if
the end position is exceeded, e.g. due to a defective limit switch.
The "safety limit
switch" must be connected to the "Emergency stop”,
which then stops the gate
movement. slack cable switches or wicket safety devices must also be connected in
the "Emergency stop" safety circuit.
f) Open/Closed/Stop input
[X9]
These control stations can be designed as pushbuttons, key-operated switches,
coded locks or external radio buttons
– and each as a
make contact element
.
[X9.1] Connect the "Open" and "Closed" buttons to
terminals 26...28
.
[X9.2] Connect the "Stop" button to
terminals 29 / 30
.
"Stop"
is a purely function input
without safety function!

The
"Open"
and
"Closed"
functions can also be actuated via channels 2 / 3 of the
optional
radio receiver
, as described on page 13.
g) Emergency stop
[X19]
This can be realised as a mushroom button or wicket safety device, etc., and is a
floating
break contact element
.
Connect the emergency stop button to
terminals 38 / 39
.
If you do
not
want to connect an emergency stop button, these terminals must be
jumpered
!
The "Emergency stop" function directly blocks the relay for the motor control. It is not
possible to start the motor via the dead-
man’s mode or by other inputs, as long as
terminals 38 / 39 are interrupted.
