PAC 520 Guia De Inicio Rapido página 4

Introduction
This document is intended for experienced engineers
who are familiar with PAC products and health and
safety considerations. An installation diagram is
given. Further information on hardware installation is
given in the installation guide provided on CD.
Information on software installation and operation is
given in documentation and help files provided with
the administration software.
Note
It is recommended that all similar controllers on the
system have the same firmware version number.
Therefore, a firmware download to the new controller
may be required, see the help file for details.
Tamper and Override Terminal
Because tamper and override are normally closed
switches, use a short piece of cable to link the TAMP
and 0V terminals and a 2k2 resistor between OVRD
and 0V terminals before powering up.
RS-485
If shielded cables are used, connect the shield on
one controller to 'Earth'. The first and last controllers
in the chain (and no others) must have the RS-485
termination jumper linked (set to IN). The red RS-
485 LED indicates when the controller is transmitting
data and green RS-485 LED indicates when there is
data on the network.
Training and Technical Support
Training courses covering the installation and use of all PAC products are regularly held at PAC Stockport.
For further information on course availability, or to discuss your specific requirements, contact the Training
Manager at the PAC address.
It is strongly recommended that any persons installing or commissioning PAC products attend a
suitable training course beforehand.
Technical Support for all PAC products is provided primarily for the use of trained engineers. Technical
support is available during normal office hours:
8:30 to 5:30pm (UK time) Monday to Friday, excluding public holidays.
End users of PAC products should first of all contact their installation or maintenance company before
contacting PAC.
