Product Recall - Immediate Action Required
GE Fanuc has discovered following issues and required your attention.
1.
VersaMax®
Thermocouple Input Module, IC200ALG630-AA and AB, Date Code Range 022 Through
131, can Experience a Heat-Related Failure
GE Fanuc
has discovered that the VersaMax Thermocouple Input Module
IC200ALG630-AA
and
AB within the date code range of
022 through
131
inclusive can experience a heat-related failure when the operating temperature
reaches approximately 105°F (40°C) or greater.
When this failure occurs, the module's inputs to the CPU switch to the
user-defined default settings. This
issue occurs only in modules within the specified date code range which covers
modules manufactured in the time period from May 29, 2000 through August 3,
2001. All IC200ALG630-AA and AB modules
within the date code range should be replaced.
Also, all users must verify that the module's input default settings are
appropriate.
Action Required
§
The affected module is the subject of a product retrofit
by GE Fanuc.
GE Fanuc recommends
that all users of the IC200ALG630-AA and AB modules within the date code range
of 022 through 131 inclusive should
return the modules to their local GE Fanuc Distributor. Returns will be for replacement at no
charge.
§
Due to the failure mode described in this Bulletin
resulting in the specified Thermocouple Input module sending to the CPU the
“user defined default input settings”, users must also
verify that their
module “default” settings are proper and safe for the application.
2.
Series 90™-30 Analog I/O Modules
IC693ALG222B and IC693ALG442B, Date Code Range 101 through 139, Can Experience
Operational Failure
GE Fanuc has discovered that
Series 90-30 Analog I/O modules,
IC693ALG222B and
IC693ALG442B, within the date code range of
101 through
139 inclusive
meaning that the module was manufactured during the time period from January 01
through September 28, 2001, can experience an operational failure after the
affected modules are power cycled.
After such a power cycle, affected
Analog I/O modules may fail, which turns off the USOK (PSOK for ALG222) status
LED, resulting in the %I + 1 status bit being reported to the CPU as a
zero. This situation will result in the
analog outputs going to zero while the analog inputs will go to an
indeterminate state. If the module is turned off for a period of time it may
again operate properly. This failure could cause unexpected equipment operation
that could result in personal injury or property damage.
All Series 90 Analog I/O modules,
IC693ALG222B and IC693ALG442B, within the specified date code range must be
replaced. The module date code is
identified on the box label as well as on the module-housing label.
Action Required
§
The affected Analog I/O modules are the subject of a
product recall by GE Fanuc. All Series
90-30 Analog I/O modules, IC693ALG222B and IC693ALG442B, within the date range
101 through 139 inclusive must be replaced.
All users of the identified Analog I/O modules within the specified date
code range must return the modules to their local GE Fanuc Distributor. Returns
will be for replacement at no charge.
§
Until the modules are returned, users must ensure
they are monitoring, in their PLC program, the %I + 1 status bit for a zero
which would give an indication that the Analog I/O module may be experiencing
this problem. (Further details on this
status bit can be found in the Series 90-30 PLC I/O Module Specifications
manual, GFK-0898, Chapters 10 & 12.)
In any case, distributors and resellers must return all
affected modules in their stock and personally contact all of their customers
who may have purchased such modules in order to ensure that they are informed
of this message and return affected modules for replacement.
