POWER REQUIREMENTS PAGE 3
3. POWER REQUIREMENTS
The Cv3 requires a DC power supply voltage b12 to +24 Volts.
This supply should be capable of delivering up to 1 Amp of current.
Connect your DC power source to the Ground (GND) and Positive (PWR)
terminals on the terminal block.
Optional Internal Battery Backup
When the Cv3 is equipped with the optional internal battery backup, it will
continue to function without primary power. The life of the battery is
dependant on unit operations and call outs during the power outage.
Should the battery voltage drop below +9 Volts, the Cv3 will disconnect
and shutdown. The internal battery backup is intended as a fail-safe during
power outages and should only be used as a temporary means to provide
power to the unit.
The internal battery charger operates with input voltages b8 and
+30 volts DC. The internal battery is limited to 1.4Ahr; if you require a
larger battery capacity, please contact our sales office for alternative
battery options.
Since a Cv3 equipped with an internal battery will continue to function in
the absence of primary power, a means of manually shutting the system
off has been provided. This feature is used when servicing or relocating
the unit. The shutdown switch is located next to the DB9 programming
connector. A forced shutdown can only be done when the primary power
is absent. Press and hold the shutdown switch for five seconds to force the
Cv3 into shutdown mode. After five seconds, the internal battery will be
disconnected and the unit will not be operational. This can be verified by
noticing that none of the indicator LEDs are on or flashing. The Cv3 will
return to the operational state when the primary power is applied again.
The internal battery option is not recommended for applications requiring
low power consumption.
