￭ Emergency stop button [S61]
The emergency stop button [S61] is an optional device (G331). Pressing the button
activates an emergency stop function of the supply unit. The button locks to open position
automatically. You must release the button before you can return to the normal operation.
Before the restart, you also need to reset the emergency stop circuit with a separate reset
button [S62].
￭ E-stop reset button [S62] and indication lamp [P62]
The emergency stop reset button [S62] is automatically installed on the door when the
supply unit is equipped with an emergency stop function (for example, oQ951,
+Q952, etc). The button is illuminated, ie it includes an indication lamp [P62]. You can reset
the emergency stop circuit with the button.
Note: The emergency stop options are described in separate option manuals.
￭ Other optional door controls
• A voltage meter is an optional device ([P5.x], G334). There is a meter on the
door and a switch [S5.x] with which you can select which phase voltage value to display.
• An AC phase current meter is an optional device ([P2.x], G335). It is also possible
to have three meters on the door - one for each phase currents (3G335).
• Tripping button for the supply breaker ([S22], Q959) is a push button on the
cabinet door for the user-defined use, for example, for tripping the breaker of the supply
transformer of the drive. The button is wired to a terminal block at the factory. The user
connects the external circuit to be controlled on site.
• An electrical on/off push button ([S23], G332) on the cabinet door for tripping
the supply unit. The button is connected in series with the operating switch. The button
trips the Run enable signal and further the main contactor/breaker of the drive.
￭ Control panel
The control panel is the user interface of the unit. For the cabinet-installed drives, the panel
is optional (J400 or +J425). With the control panel, you can:
• start and stop the unit
• view and reset the fault and warning messages, and view the fault history
• view actual signals
• change parameter settings
• change between local and external control.
To be able to start and stop the unit by the control panel, you must have the Run enable
signal and Start enable signal on (1) on the control board. Normally this means, that you
must have the operating switch on the cabinet door in ENABLE/RUN position. The control
panel must also be in local control mode. You can select the mode with the Loc/Rem key
on the panel.
For the instructions on the use of the panel, see ACX-AP-x Assistant control panels user's
manual (3AUA0000085685 [English]).
￭ PC connection
There is a USB connector on the front of the control panel that can be used to connect a
PC to the drive. When a PC is connected to the control panel, the control panel keypad is
disabled.
