STARTING THE DISPLAY
Power-up Validation
The Home page will appear and the POWER LED will be
blinking when the device is properly powered. Select the
Setup button to adjust the contrast as desired.
If the screen is dim, check pin 1 wiring connections.
NOTE: An Advanced Startup screen displays for five sec-
onds after power-up before the Home page displays.
This screen allows the user to upgrade the software
in the 833-3577 System Display (see “Preface” on
page 2) and should normally be bypassed.
Communication Validation
Three LEDs exist for I/O traffic, one for the Ethernet port and
two for the Modbus™ ports.
1. Make sure the LEDs are blinking.
2. If the LEDs are not blinking:
a. Make sure the proper connections have been made
between the 833-3577 Modbus™ Com 1 Port and
the first 833-3639 device in the Modbus™ global net-
work.
b. See “Wiring” on page 3 for proper wiring of the 833-
3577 9-pin Header Connections.
Home Page
Make sure a screen similar to Fig. 4 appears after the 833-
3577 is completely powered up.
On 833-3577 System applications, each 833-3639 in the
hydronic system is represented on the Home page by an icon
and name. Pressing the icon allows the user to zoom in on
that boiler and see specific details about it. These details are
provided on a new page, which can include additional buttons
that display additional detail and operation information, which
itself leads to other pages. The pages are traversed in a tree
structure method, as shown in Fig. 5.
