GFK-0787B A-3Appendix A TÜV Certification
The installation procedures in the Series 90-70 Programmable Controller Installation Manual
(GFK-0262D) and this GMR User’s Manual (GFK-0787A) are to be closely observed and complied
with, especially the grounding procedures in chapter 3 of the Series 90–70 Programmable Controller
Installation Manual (GFK-0262D).
All GMR components must be installed in a panel or cabinet which offers protection equal to or
greater than specification IP54. For EMC purposes, the enclosure must provide protection equal
to or greater than an enclosure having the following characteristics: Steel sides with a thickness
of 0.040 inches, no RFI gasketing and all enclosure sides grounded to a common point with
grounding straps equal to or larger than #14 AWG. The panels or cabinets must be closed during
operation of the system. They may be opened only during maintenance or for short term
supervised operation.
The on-line programming option must be set to DISABLED in the configuration.
The simplex shutdown option must be set to be enabled at 60 seconds.
For applications needing to meet DIN VDE 0116 specifications, the maximum Input-to-Output
response time allowed is 1.0 second. To ensure this response time is met under all circumstances,
the maximum watchdog timer setting must be one of the following, whichever is smaller.
((2 * the typical scan time of the application program) – 10 milliseconds)
OR
310 milliseconds (if Genius bus baud rate = 153.6K)
250 milliseconds (if Genius bus baud rate = 76.8K)
130 milliseconds (if Genius bus baud rate = 38.4K)
The Data and System Fault actions must be set as follows: Data Fault – DIAGNOSTIC, System
Fault – FATAL
All redundant I/O groups must be configured to be autotested and the autotest interval must not
exceed a maximum of 480 minutes (8 hours).
The write access length parameters for %I, %AI, %Q, and %AQ must be set to 0.
If the configuration is set to allow write access, the TÜV Maintenance Override document must be
complied with. This document is reprinted in Appendix B of this manual.
Autotesting must be set to ENABLED for all used circuits of each discrete input group.
Vote Adaptation must be set to 3–2–0 for all used circuits of each discrete input group.
The Duplex State must be set to 0 for all used circuits of each discrete input group.
The Default State must be set to 0 for all used circuits of each discrete input group.
Autotesting must be set to ENABLED for all used circuits of each discrete output group.
Normal State must be set to ON for all used circuits of each discrete output group.
Vote Adaptation must be set to 3–2–0 for each analog input group.
The Duplex State and Default State settings for each analog input group are dependent on the
application and must be set as follows:
For High Limit processing The Duplex State must be set to High
The Default State must be set to Max.
For Low Limit processing The Duplex State must be set to Low
The Default State must be set to Min.
For each analog input channel, the Threshold Discrepancy Percentage must be set to 0% or to a
percentage value that causes a discrepancy if inputs at the low portion of a range vary by an
amount more than that already allowed by the Limit percentage setting.
The GMR configuration utility must be used to print the GMR-specific configuration data. The
TÜV site engineer will use this printout to verify the configuration data with the requirements of
the overall application.
