WARNING EXPLOSION HAZARD
Substitution of components may impair suitability for use in Class I,
Division 2 environments.
When the ControlWave ExpressPAC is situated in a hazardous location,
turn off power before servicing or replacing the unit and before
installing or removing I/O wiring.
Do not disconnect equipment unless the power is switched off or the
area is known to be non-hazardous.
4.1 Powering Up/Powering Down the ControlWave ExpressPAC
The ControlWave ExpressPAC receives power either from a solar panel
and factory-supplied battery or from an external bulk power supply
attached using connector TB1 on the CPU/System Controller board. It
can also receive power through alternate connector TB2 on the same
board. Chapter 2 includes instructions for wiring power to the
ControlWave ExpressPAC. See Figure 2-3 for the location of these
connectors.
Power Up To apply power to the ControlWave ExpressPAC, plug in connectors
TB1 and optionally TB2 on the CPU/System Controller board. If your
ControlWave project resides in flash memory, the project will load into
SRAM and begin execution. Depending upon the setting of the SRAM
control switch, retain variable values may load as well.
Caution
When you disconnect power from the ControlWave ExpressPAC, your
running control strategy is erased from SRAM, as is any process data
not stored in retention mode. When configured for retention and the
backup battery remains good, SRAM stores the last states of all I/O
points, audit/archive data not residing in FLASH, the values of all
variables marked RETAIN, the values of variables stored in the static
memory area, and any pending unreported alarm messages.
