9.1 UPS Monitoring through CPU
Programmable Input Ports
Use the CPU programmable input port to connect the
external UPS to the D6600 for power monitoring.
Connect the monitoring port from the UPS to
matching pins on the D6600 CPU Programmable
Input/Output port (Figure 12). 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
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 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 13).

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
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
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.
