GEMTEQ I/O 7. Installation and Commissioning
7.4 COMMISSIONING
GUIDANCE
The GEMCAN I/O Scanner and GEMTEQ I/O will have to be configured to meet particular
application requirements. Because these requirements vary for each GEM80 application this
section of the manual only includes general commissioning guidance about the method to be
followed. The instructions required for each application should be discussed with CONVERTEAM
or an approved System Builder.
7.4.1 Preparation
Before starting to commission a GEM
80 system, you should already have:
(a) Installed the equipment and cabled it up, including all earth (ground) connections as
given in this section;
(b) Cabled up the watchdog and safety circuits in accordance with the guidelines given in
this section and checked their operation;
(c) A suitable GEM80 Programming Package with a stock of suitable storage media;
(d) Ensured that all pertinent regulations for earthing/grounding of the equipment have been
adhered to.
7.4.2
Documents Required
During commissioning the following documents will be required in addition to this manual:
(a) A User/Technical Manual for the particular GEM 80 Programming Package in use;
(b) 'GEM 80 Ladder Diagram Programming Manual', Publication No.T300;
These documents will enable test programs to be written to check out the equipment.
7.4.3
Handling Precautions During Setting Up of Equipment
The following precautions must be taken during testing/setting up operations on equipment
containing printed circuit boards (PCBs) with Electrostatic Sensitive Devices (ESDs):
(a) All test equipment must be grounded to a common earth point;
(b) The system power and test equipment must be switched OFF before making or breaking
any connections;
(c) When possible, power supply voltages should be applied before signal inputs, and
should be maintained until signal inputs are removed;
(d) Dielectric strength and insulation resistance tests should not be carried out with the
PCBs installed in the equipment;
(e) Do not use audible continuity tests on PCBs;
(f) Do not use 'Freeze' Aerosols on PCBs.
