Setting the Power Loss Time Dela (1771ĆP5E onl )
Power loss time delay is the time period from when the power
supply input voltage drops below 20.5V dc to when the power
supply resets the processor enable signal on the I/O backplane.
When this signal is reset, the resident PLCprocessor or adapter
module stops processing data to/from the modules in the I/O chassis.
You set the configuration jumper as follows:

If your input modules and power supply use power from the same
source and the input module time delay is greater than the power loss
time delay of the power supply module, input module data integrity
is preserved. If using 2 power supplies, do not exceed the specified
isolation voltage (see Specifications).
!
ATTENTION Exercise care when you configure your system for
possible power loss. You should consider:
•input module time delay
•power loss time delay
•incoming power quality
•control system response to input information

The power supplies are modular components of the 1771 I/O system.
They must be properly installed in a system chassis. Refer to
publication 1771–IN075 for information on acceptable chassis
installation and proper grounding requirements.
To install the power supply module in the I/O chassis, proceed as
follows:
!
WARNING If you insert or remove the module while
backplane power is on or attach or remove
wiring to the terminal block, an electrical arc can
occur. This could cause an explosion in
hazardous location installations. Be sure that
power is removed or the area is nonhazardous
before proceeding.

2. Turn the power supply module power switch OFF.
3. Identify the slot location of the chassis into which the power
supply will be installed.
4. Place the printed circuit board on the rear of the module into the
plastic tracks on the top and bottom of the I/O chassis which
guide the module into the chassis.
5. Do not force the module into the backplane connectors. Apply
firm, even pressure on the module to seat it properly.
6. Snap the chassis latch over the top of the module to secure its
position.
7. Make power connections as described in “Making Input Power
Connections” below.
Making Input Power Connections

The power supply modules are designed to operate in parallel with:
•another 1771-P3, -P4, -P5 or -P5E power supply (Note: The
1771-P5 and -P5E power supplies are designed to operate in
parallel only with another 1771-P5.) (Refer to Table A and
Table C.)
•a 1772-LSP, -LWP or -LXP processor (Refer to Table B.)
Note: Paralleling 2 modules, even when using different power
sources, does not provide redundancy.
If 2 power supplies are used, do not exceed specified isolation
voltages.
To parallel 2 modules, proceed as follows:
1. Make certain that both power supply module power switches are
off.
2. Connect the power supply paralleling cable (cat. no. 1771-CT)
from the P/S Parallel port on the first power supply module to the
P/S Parallel port on the second module as shown below. Note:
Route the cable around the top of the I/O chassis to avoid induced
voltages.

3. Turn on both power supplies simultaneously.
!
ATTENTION To avoid driving the first of two paralleled power
supplies into an overcurrent condition that would
shutdown the module, you must simultaneously
turn on both power supplies.
The power supply module has a green indicator light (labeled P/S
ACTIVE). It indicates the operating condition of the module, and
can be used for diagnosing faults.
The module monitors itself for:
•overvoltage
•undervoltage
•overcurrent
Any of these conditions will shut down the power supply. Following
a shutdown, turn the power supply off for at least 15 seconds (-P3
and -P4) or 45 seconds (-P5 and -P5E) before you turn it on again.

Follow the procedure below to isolate and correct possible faults.
1. Turn the power supply off and wait at least 15 seconds (-P3 and
-P4) or 45 seconds (-P5 and -P5E) before you turn it on again.
2. Turn the power supply on.
3. If the system operates properly, you are finished. If the indicator
does not turn on, turn the power supply off and wait 15 seconds
(-P3 and -P4) or 45 seconds (-P5 and -P5E).
4. Remove the paralleling cable (if equipped) to verify independent
operation of each power supply.
!
ATTENTION Remove input power to the I/O chassis before
removing the power supply module from the
chassis. Failure to do this may result in injury to
personnel and/or damage to equipment.
5. Pull the power supplies halfway out of the chassis to test them
under no load conditions.
6. Turn on one power supply.

8. If you have only one power supply in your chassis and it passed
step 7 (the P/S ACTIVE light turned on), verify that the power
supply is not overloaded by performing steps 9 through 11.
9. Turn the power supply off and wait 15 seconds (-P3 and -P4) or
45 seconds (-P5 and -P5E).
10. Firmly seat the power supply in the chassis.
11. Restore power to the I/O chassis, and turn the power supply
module on.

Checking for Open or Shorted Paralleling Cable
Important: Continue with this procedure only if you are using two
power supply modules in the same chassis. This
procedure checks for an open or shorted 1771-CT
paralleling cable.
Before you begin, turn I/O chassis power off. Both power supply
modules should be turned off and partially pulled out of the chassis.
!
ATTENTION Remove input power to the I/O chassis before
removing the power supply module from the
chassis. Failure to do this may result in injury to
personnel and/or damage to equipment.
1. Test the 1771-CT paralleling cable by verifying the ground
connection between power supplies.
2. Test for a short circuit by performing steps 3 through 5.
3. Plug one end of the paralleling cable into one of the power supply
modules (the other end should not be connected).
4. Turn the power supply on. If the P/S ACTIVE indicator turns on
this end of the cable is okay.
5. Unplug the cable, and plug the other end of the cable into the
power supply.

6. Perform steps 7 through 9 to test for an open circuit in the
paralleling cable.
7. Turn both power supply modules off. Connect the paralleling
cable to each supply.
8. Turn one power supply module on. The P/S ACTIVE indicators
on both supplies should not turn on.
9. Turn the first power supply off and the other power supply
module on. The P/S ACTIVE indicators on both supplies should
not turn on.
If either of the P/S ACTIVE indicators turn on, the paralleling
cable has an open circuit. Replace the cable.
10. To test for a paralleling fault, turn both power supply modules off
and wait 15 seconds (-P3 and -P4) or 45 seconds (-P5 and -P5E).
11. Verify that the paralleling cable is properly connected, and then
turn both power supplies on simultaneously. The P/S ACTIVE
indicators on both supplies should turn on.
12. If the P/S ACTIVE indicators on both supplies do not turn on,
replace both supplies, one at a time, with known good power
supplies in order to isolate the faulty power supply module.
13. If all tests have passed up to this point, turn both power supply
modules off simultaneously and wait 15 seconds (-P3 and -P4) or
45 seconds (-P5 and -P5E). Check for backplane loading by
performing steps 14, 15 and 16.
14. Firmly seat the power supplies in the chassis.
15. Restore power to the I/O chassis, and turn both power supply
modules on simultaneously.

16. Check for proper dual power supply module operation. If
backplane loading is within acceptable limits and the P/S
ACTIVE indicators do not turn on, replace both power supply
modules, one at a time, with known good power supply modules
in order to isolate the faulty module. The system should operate
normally.
