ACM 400 S

ACM 400 S motor control unitWarning!Do not connect the gate drive unit to the motor, until you are convinced the motorruns in the correct rotational direction – e.g. after electrical startup. Otherwisethere 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 "safetylimit switch" downstream of the normal limit switch, if the gate causes a hazard ifthe end position is exceeded, e.g. due to a defective limit switch. The "safety limitswitch" must be connected to the "Emergency stop”, which then stops the gatemovement. slack cable switches or wicket safety devices must also be connected inthe "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!Gate status “Open” pressed “Closed” pressed “Stop” pressedstanding in limit position “Open“ - closes -standing in limit position “Closed“ opens - -standing in “Partly open” position opens closes -Stands somewhere along theopens closes -pathopens menu “D“ value: 00 Stop Stop Stop01 - Stop02 Stop closes03 - closescloses menu “D“ value: 00 Stop Stop Stop01 opens Stop02 Stop -03 opens -“Emergency stop“ is actuated - - -Automatic closing modeAs long as it ispressed the gateremainspermanently opencloses, keep opentime is ignoredStop, keep opentimerestartsThe "Open" and "Closed" functions can also be actuated via channels 2 / 3 of theoptional 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 afloating 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 bejumpered!The "Emergency stop" function directly blocks the relay for the motor control. It is notpossible to start the motor via the dead-man’s mode or by other inputs, as long asterminals 38 / 39 are interrupted.8 / 24
