AC ON (D34) –
Green
Lights when any AC voltage is present on the AC input. It does not
indicate that the voltage is sufficient for proper operation of the
CKM-FPO power supply. See the AC FLT (D43) – Yellow LED for
AC voltage out of range indication.
Earth Ground Fault
Detection (JP2)
The EARTH GND DET jumper enables or disables Earth Ground
(EG) fault detection as follows:
• Jumper ON enables EG fault detection
• Jumper OFF disables EG fault detection
Earth ground fault detection detects continuity between earth
ground and any voltage output or DC common on the system.
NOTE: Do not enable more than one system component for earth
ground detection. Enabling more than one component will cause
conflicts.
FlexIO Connection Supplies the fault and FAI status between the power supply and any
accessory boards in the system. Use the cable supplied with the
accessory boards.
DataLink
Connection
Allows optional programming and monitoring of the power supply
via a computer or through the optional NL1 network module.
DataLink cables and the PowerCom software package for
accessing these features are available separately from LifeSafety
Power.
For more information, refer to the documentation provided with the
PowerCom software.
