Install and Operate the Junction Boxes Chapter 4
After power has been applied, perform the following steps to verify that the IP65
junction box is performing correctly.
1.
Verify that the power status indicator on the front of the IP65 junction box
is lit and green in color.
2.
Verify that the Ethernet status indicator on the front of the IP65 junction
box is lit and green in color.
3.
Connect a second generation MobileView terminal.
a. If the MobileView terminal has an illuminated E-stop button, verify
that the illuminated E-stop status indicator on the front of the IP65
junction box is lit and green in color.
b. Verify that the status indicator bar on the front of the IP65 junction
box is lit and solid green in color.
4.
Push the illuminated E-stop push button on the second generation
MobileView terminal to trigger a stop.
Verify that the status indicator bar on the front of the IP65 junction box is
lit and solid red in color.
5.
Disconnect the MobileView terminal.
a. Verify that the status indicator bar on the front of the IP65 junction
box changes from solid red to solid yellow.
b. Verify that the status indicator bar reduces one blinking yellow light
after each 1.67 seconds of disconnect time.
c. After 10 seconds of disconnect time, verify that all six lights of the
status indicator bar are off and subsequently replaced by a blinking
yellow status indicator bar.
The blinking yellow status indicates that the relay outputs of the IP65
junction box are de-energized and therefore open, which triggers an
emergency stop of the system or machine.
IMPORTANT See IP65 Junction Box Status Indicator Lights on page 52 or Troubleshoot the
IP65 Junction Box on page 90 for what the following colors represent.
IMPORTANT When you disconnect a second generation MobileView terminal from
an IP65 junction box, it begins a 10-second countdown to a system
emergency stop. Therefore, you have 10 seconds to reconnect a second
generation MobileView terminal or black bridge connector to keep the
safety circuit complete.
IMPORTANT Only perform step c if you are commissioning the unit, performing
maintenance, or testing safety equipment, because step c triggers
a system emergency stop.
WARNING: An IP65 junction box does not protect against the restart
of a system or machine. Separate protection must be provided on the
system or machine, such as an acknowledgment key.
