Digital I/O modules PLC (P/N 322-092202-02) are utilized to collect element status
information from Element Monitor Board (P/N 370-101831-01). Each Element Monitor
Board has four monitoring circuits. Each circuit utilized a transformer coil and rectifier
network to pickup and convert the element status to a low voltage output signal. This output
signal is received by a digital I/O module. Each digital I/O module can accommodate up to
four signal inputs.

In conjunction with the four digital inputs, each module has four LED’s that illuminate when
its associated input is active. Input information is transmitted back the system controller for
processing, alert notification, and display.
The Element Monitor Window provides active element status displays. For each element leg
displayed, the following status information is provided:
1
8-Module rack identification
a)
First Board (element sensors 1-32)
b)
Second Board (element sensors 33-64)
c)
Third Board (element sensors 65-96)
2
I/O module address & channel identifier
3
Sensor Location; Zone, Dryer, or Edge Heat number and (T)op, (B)ottom elements,
(R)ight, or (L)eft edge heat.
4
Element Status (OK) or (Fail)
When an element failure is detected, an alert condition is enabled and a status message
denoting the location of the failed element. Only the first failed element detected within the
same zone/dryer/edge will be displayed on the process screen. However, the Element
