2.7.2 VIEWER TEMPERATURES
The temperatures in the front and rear viewer cabinets are displayed. These
temperatures are provided for information only, but since temperature is an
important factor in fluorescent lamp light output, it is important to check these
temperatures when adjusting lamp level. Never make final lamp current settings
unless the viewers are at normal operating temperature. See Section 4-6 for more
information on lamp light level adjustment.
2.7.3 STATUS INDICATORS
The status of monitored systems (Power Supplies, Air Pressure and Viewer Open) is
displayed as red or green buttons. If the system is normal, the button will be green.
If the system has a fault, the button will be red.
The status of the remote PLC control interface (if used) is also displayed as red or
green buttons. The upper section of the button displays the feeder on/off control
source, green for local or red for remote. The lower section of the button displays
the feeder rate control source, green for local or red for remote.
The status of the regulated lamp ballasts for the front lamps and rear lamps is
displayed, with green for normal and red for outside the control range.
The status of the feeders and hopper level sensors is displayed in split buttons. If
the feeder is on, the upper half of the button will be green. If not, it will be red. If
the hopper sensor is covered by product, the lower half of the button will be green.
If not, it will be red.
The ejector circuits are monitored and their status is displayed as red or green
buttons. If the ejectors are normal, the buttons will be green. If there is a fault on
an ejector, the corresponding ejector status button will be red. When an ejector has
a fault, the feeder for that particular channel will be turned off.
