6.8 Installation of Optional Modules
6.8.1 Introduction
The GEM80-500 Controller may be fitted with up to five optional modules. These
provide additional features such as a Basic I/O Interface, Verification I/O Interface,
Serial Communications Ports, FIP Comunications and GEMCAN I/O Scanner.
Installation instructions for these modules are included at 0.
An optional Ethernet Interface Module can also be added to the controller assembly
and this has a separate position allocated on the controller motherboard. Separate
installation instructions are included at 6.8.7.
If any of these modules are to be fitted after initial installation of the controller, the
controller must first be powered down and removed. It is recommended that the
installation procedures in this section are carried out with the controller at a workstation
that provides the necessary clean and static handling conditions.
6.8.2 Protection of Equipment from Static Damage
Protective measures are required when handling any of the optional modules to
prevent damage to Electrostatic Sensitive Devices (ESDs). The following rules must be
observed:
(a) Personnel handling the modules should NOT wear outer clothing which will
generate a static charge, e.g. synthetic materials like nylon, cotton is preferable.
(b) All personnel handling the modules should put themselves in contact with a
grounded surface before removing any modules from their protective packing or
from equipment. The antistatic equipment should be kept on during all module
handling.
(c) Avoid finger contact with devices on the modules and with its connectors
(d) If it is necessary to place any module down 'unprotected', place on a static
shielding bag, or other equivalent material
(e) Modules should be protected by a static-shielding bag when out of the equipment.
6.8.3 Setting I/O, Serial Communications and GEMCAN I/O Module Jumper Links
The I/O Interface Modules 9713-4020 and 9713-4021, the Serial Communications
Module 9714-4020, and the GEMCAN I/O Scanner Module 9720-4020, each have a
2-position jumper link arrangement. A jumper link has to be set depending upon the
module function and its use in the controller i.e. the first or second module of a
particular type – refer to Table 3-1 for more details about configuration of modules.
Table 6-1 lists the link settings for each Module and
Figure 6-3 shows the linking positions on a module.
WARNING
The supply and Watchdog signal circuit to the controller must be
disconnected by removing both incoming cable sockets.
