Chapter 3 Controller Descriptions and Operation

Based on equipment functions, the message displayed in the HOME screen may
be different and mainly includes as follows:
CT, Cabinet Temperature, standard function module, including actual temperature and working
temperature. Before temperature control starts up, the working temperature is displayed 0.00,
while after start-up, working temperature correspondences to the actual setting. For
[CONSTANT] operation, the working temperature is a fixed value, while for [PROGRAM]
operation, the working temperature will change if the successive two values are set to ramp.
RH, standard function module, including actual humidity and working humidity. Before humidity
control starts up, the working humidity is displayed 0.00, while after start-up, working humidity
correspondences to the actual setting. For [CONSTANT] operation, the working humidity is a
fixed value, while for [PROGRAM] operation, the working humidity will change if the
successive two values are set to ramp.
Humidity control is possible when temperature comes within ±5 °C of the setting. Otherwise the
humidifier will not work, and the OUTPUT for HUMD will be 0 as illustrated in screen of Details
for Immediate Constant (Fig 14).
VL, Visual Light, standard function module, including visual light setting and actual dimming
output. Light intensity can be set from 0~100%, where 0% means no light, 1~100% means
dimming between 1~100%. Once light radiation is enabled, or the light intensity is changed
from one to another, a smooth and comfortable light change is achieved according to a set
and editable dimming rate. Once outside door open and the operator exposed to strong
optical light, if the active light intensity is higher than a safety value, the light intensity will be
dimmed automatically to the safe value. The set value will be resumed once the door closed.
The Light intensity may be measured by optional light sensors, including quantum sensor for PPF,
photometric sensor for lux illuminance, and ultraviolet sensor for UVA measurements. The
display can be instant radiation or accumulative radiation, including

.d (DLI), klux.h and W/m

.h for different purpose. The accumulative radiation
measurements have the advantage of more accurate result to compensate instability of the
light intensity as affected by voltage fluctuation, temperature and service life of the light. With
the setting of an accumulative radiation, visual and audible alarm can be used for precise
radiation control, for example for compliance with ICH Q1B.
The trend chart is used for record and presentation of temperature and relative humidity changes
with the time, including actual temperature (Pv), set temperature (Sv), actual humidity (Pv)
and set humidity (Sv). The left Y axis is temperature (
°
C), the right Y axis is relative humidity
(%RH), while the X axis is time. The chart start from left and develop to the right, and will pan
automatically to the left once the chart tends to be full. The scroll bar at the bottom of the
chart makes review of the temperature and humidity trend vivid and convenient. By touching
