5.3.1 Fusion4 IR Controller
The Fusion4 IR Controller uses infrared (IR) signals to transmit the
ASCII characters to the MSC-L. This allows the operator to make
adjustments in programming the MSC-L without removing the cover of
the explosion proof enclosure on-site.
The infrared receiver on the MSC-L is designed to be unaffected by
interference from light sources other than the Fusion4 IR Controller. All
prompts requiring an operator response are clearly indicated on the
display of the MSC-L.
The Fusion4 IR Controller has all the infrared commands permanently
stored in its micro-controller. Due to this, if the batteries are drained, it
can be restored to complete operation by inserting a fresh set of
batteries. The Fusion4 IR Controller has a “sleep” mode to reduce
battery consumption. At first use, or after a period of inactivity of
approximately 30 seconds, the
[ATTN]
key must be pressed to “wake-
up” the Fusion4 IR Controller. Then the
[SEND]
light blinks, indicating
that the Fusion4 IR Controller is ready for operation.
