9.1 UPS Monitoring through CPU
Programmable Input Ports
Use the CPU programmable input port to connect the
external UPS to the D6600/D6100 for power
monitoring. Connect the monitoring port from the UPS
to matching pins on the D6600/D6100 CPU
Programmable Input/Output port (Figure 14). Wiring
must run from the receiver through the UL Listed rack,
exit the rack through a conduit connection, and
terminate at the external UPS for UL applications. Set
up the D6600/D6100 from Menu 2.2.27 CPU
Programmable Input 1 for Input 1; Menu 2.2.28
CPU Programmable Input 2 for Input 2. Refer to the
D6600/D6100 Program Entry Guide (P/N: 4998122702)
for more information.
9.1.1 Input Default Connection Configuration
• The I/O ports work with dry contact outputs.
• The open circuit input voltage on the input
measures between 9 V and 12 V.
• UPS Battery OK (restore) – contacts closed
• UPS Battery Low input – contacts open
You can apply other output sources to the input wiring
as long as you follow these guidelines:
• The maximum input voltage allowed without
causing damage to the input is 24 VDC.
• For UPS “Battery OK” (restore), the input range
must be between 0 V and 1 V.
• For UPS “Battery Low,” the input range must be
between 3 V and 24 V.
Because the input state is undefined in
the voltage range, input voltages between
1 V and 3 V can cause abnormal results.
This might cause unexpected results such
as toggling between “Battery Low” and
“Battery OK.”
9.1.2 Input Reverse Connection Configuration
If the input must be the opposite polarity for correct
operation, place an external transistor circuit between
the UPS output signal and the D6600 I/O input
(Figure 16).
Follow these guidelines for correct operation:
• The maximum input voltage allowed without
damaging the input is 24 V.
• UPS Battery OK (restore) input range from the
UPS operates between 5 V and 24 V.
• UPS Battery Low input range operates between
0 V and 0.5 V

1 – From UPS Battery OK signal 5 to 24 V
2 – 22 k to 39 k
3 – Battery Low signal 0 to 0.6V
4 – To I/O input
5 – Any general purpose NPN transistor
Operating the input as an analog input
between 0.5 V and 5 V might cause
abnormal results. This input state is not
defined and might change expected
results
Reverse configuration is not for use in UL
Listed applications.
9.2 Automation Link Monitoring (COM3)
through CPU Programmable Output
Ports
The output connections on the I/O port have an open
collector transistor output that can activate an external
sounder or light if the automation system fails.
Configure external devices using the
specifications listed in Table 9. Outputs
are not verified by UL.
