NOTES:
•
The 115V to 24V transformer provides power for the Edge Controller and the Sequencing
Isolation Valve. It is mounted on the back side of the Main Power Panel. All other
components in the Power Panel are mounted on a DIN rail on the front side of the panel.
•
All electrical conduit and hardware must be installed so that it does not interfere with the
removal of any unit covers, inhibit service/maintenance, or prevent access between the
unit and walls or another unit.
2.11 FIELD CONTROL WIRING
–
I/O Board
Each unit is fully wired from the factory with an internal operating control system. No field control
wiring is required for normal operation. However, the Edge Controller used with your Benchmark
unit does allow for some additional control and monitoring features. Wiring connections for
these features are made on the Input/Output (I/O) board located behind the
unit’s removable
front panel, as shown in Figure 2-10.
