Install and Operate the Junction Boxes Chapter 4
Reconnect Power to IP65 Junction Boxes
If the IP65 junction box is powered off, the relays of the emergency stop circuits
are no longer actively held closed and the emergency stop circuit is subsequently
opened, which is comparable to an activated E- stop.
When powered off, the input states and E-stop state at that time are saved in the
IP65 junction box memory. When power is restored, these saved states are
subsequently retrieved.
Therefore, the IP65 junction box can have the following states.
Connected/Disconnected Timer State
A second generation MobileView terminal or a black bridge connector must be
connected to the IP65 junction box. When you disconnect one to connect the
other, the IP65 junction box recognizes the disconnection and enters a timer
state, when the operator has a maximum of 10 seconds to reconnect a device.
During this disconnected time, the E-stop of the IP65 junction box is bypassed
until a MobileView terminal with an unactivated E-stop push button or a black
bridge connector is connected.
State Description
Normal A second generation MobileView terminal (with an unactivated E-stop push button) is connected.
Bride active A black, 22-pin bridge connector is connected.
E-stop The E-stop push button on the second generation MobileView terminal has been activated.
Error state The E-stop push button on the connected, second generation MobileView terminal and the
retrieved E-stop in the IP65 junction box memory are not the same. In this case, the E-stop push
button of the connected MobileView terminal is unactivated but the saved, retained E-stop in the
IP65 junction box memory is activated. Therefore, the E-stop push button on the MobileView
terminal must be activated and then unlocked to reset the IP65 junction box.
If Then
The connected, second generation MobileView
terminal has an illuminated E-stop push button that
is unactivated
(1)
(1) You must first configure an IP65 junction box to recognize an illuminated E-stop push button on a second generation
MobileView terminal. For more information, see DIP Switch on page 46 .
The E-stop push button is recognized by the IP65 junction box
and it is illuminated.
The connected, second generation MobileView
terminal has an illuminated E-stop push button that
is properly configured but activated The E-stop push button on the second generation MobileView
terminal must be deactivated and reset before the IP65
junction box returns to the normal state mentioned in
Reconnect Power to IP65 Junction Boxes .
A black bridge connector is being connected The black bridge connector must be connected within 10
seconds for the IP65 junction box to recognize the device and
enter the bridge active state mentioned in
Reconnect Power to
IP65 Junction Boxes .
No second generation MobileView terminal or black
bridge connector is connected within 10 seconds The IP65 junction box timer state times out and an E-stop is
triggered.
