Fuse Protection and Blown Fuse Diagnostics
This section describes fusing characteristics for the following modules:
• 1746-OBP16
• 1746-OVP16
• 1746-OAP12
Fuse Protection (1746-OBP16 and 1746-OVP16 modules)
The fuse on the 1746-OBP16 and 1746-OVP16 modules (shown on Location of Jumpers and
Fuses for 1746-OBP16 and 1746-OVP16 Modules on page 9) provides short-circuit protection
for 13 mm2(16 AWG) or larger wiring to external loads. In the event of a short circuit on an
output channel, it is likely that the transistor associated with that channel will be damaged. In
this event, the module should be replaced or the load moved to a spare output channel.
The fuse does not provide overload protection. In the event of an overload on an output channel,
it is likely that the fuse will not blow and the transistor associated with that channel will be
damaged. To provide overload protection for your application, user-supplied fuses should be
installed externally and properly sized to match your individual load characteristics.

Fuse Protection (1746-OAP12 modules)
A fuse is provided on each common of the 1746-OAP12 module (shown on Location of
Jumpers and Fuses for 1746-OAP12 Module on page 10) for a total of two fuses. The fuses are
designed to protect the module from short-circuit conditions. The fuse does not provide
overload protection. In the event of an overload on an output channel, it is likely that the fuse
will not blow and the output device associated with that channel will be damaged. To provide
overload protection for your application, user-supplied fuses should be installed externally.
The recommended fuse for overload protection is SAN-O HT. Select the fuse rating according
to your load. Do not use HT fuses rated higher than 2.0 Amps.
Blown Fuse Diagnostics
If the fuse blows on the 1746-OBP16, 1746-OVP16, or 1746-OAP12 module, the following
occurs:
• The blown fuse LED indicator will illuminate, provided power (5V DC via backplane
and load power via external supply) is applied to the module.
• A processor error will occur if JP1 connects pins 2 and 3. (See figures on page 9 and
page 10.)

Replace Fuses
1. Remove SLC 500 system power and correct the conditions causing the short circuit.
2. Remove the output module from the chassis.
3. Remove the fuse.
• 1746-OBP16 and 1746-OVP16 modules: Use a wide-tipped, slotted-head
screwdriver to remove the blown fuse. Slide the screwdriver tip under the fuse and
use a twisting motion to pry the fuse from the fuse clip. Use care so that the printed
circuit board and surrounding electronics are not damaged.
• 1746-OAP12 module: A fuse holder is provided with each fuse. Simply grasp the
fuse holder with needle-nose pliers, or your fingers, and pull it out.
4. Replace the fuse.
• 1746-OBP16 and 1746-OVP16 modules: Center the replacement fuse over the fuse
clip and press down. If you use a tool to press the fuse in place, apply pressure to the
metal end caps only, not the center of the fuse.
• 1746-OAP12 module: Insert a new fuse into the fuse holder, align the fuse holder on
fuse clips, and press down.
5. Replace the output module in the chassis.
6. Restore SLC 500 system power.
7. Clear processor fault bits as indicated in the steps provided on page 13.
Electronically Protected Modules (1746-OB6EI and 1746-OB16E)
The electronic protection of the 1746-OB6EI and 1746-OB16E modules have been designed to
provide protection for the modules from short circuit and overload current conditions. The
protection is based on a thermal cut-out principle. In the event of a short circuit or overload
current condition on an output channel, that channel will limit current within milliseconds after
its thermal cut-out temperature has been reached. All other channels continue to operate as
directed by the CPU (processor) module.
ATTENTION: Never install, remove, or wire modules with power applied to chassis.
IMPORTANT
The modules do not provide protection against reverse polarity wiring or
wiring to ac power sources. Electronic protection is not intended to replace
fuses, circuit breakers, or other code-required wiring protection devices.

E-FUSE LED Indicator
Auto Reset Operation
Short Circuit/Overload Current Diagnostics
If a short circuit or overload current condition occurs on an output channel:
• the E-FUSE LED indicator will illuminate provided that power is applied to the module.
Power required: 5V DC via backplane and load power via an external supply.
• all other channels continue to operate as directed by the CPU (processor) module.
IMPORTANT
The 1746-OB6EI and 1746-OB16E modules perform auto-reset under overload
conditions. When an output channel overload occurs, that channel will limit
current within milliseconds after its thermal cut-out temperature has been
reached. While in current limit, the output channel can cool below the thermal
cut-out temperature allowing the module to auto-reset and resume control of the
output channel as directed by the processor until the thermal cut-out
temperature is again reached.
Removing power from an overloaded output channel would also allow the output
channel to cool below the thermal cut-out temperature, allowing auto-reset to
occur when power is restored. The output channel would operate as directed by
the processor until the thermal cut-out temperature is again reached.
To avoid auto-reset of an output channel under overload conditions, an external
mechanical fuse can be used to open the circuit when overloaded.
