Installation 15
The contact output is assigned and used depending on the controller configured mode of operation.
When this contact is connected to an inductive load, an external arc suppression network is required for
contact protection.
2.4.2.6 Datalink Connections
Datalink is an interrogator/responder serial interface capable of supporting 32 instruments on a single net-
work. It uses an RS485 physical interface. The Datalink wiring diagram for this instrument is provided as
. Complete coverage of the Datalink is provided in the SUPERVISOR-PC Instruction Bulletin
53SU5000.
2.4.3 Factory Set Calibration
Each unit contains individual factory set entries that calibrate the two analog inputs and analog output.
There is a calibration sheet supplied with each instrument that should be retained for future reference
when the installation is completed. Refer to
for additional information.
2.5 Grounding
Installations are expected to have access to an independent, high quality, noise-free point of earth refer-
ence. The system should be connected by a dedicated, low resistance (less than one ohm) lead wire
directly to the installation’s point of earth reference. This ground reference is referred to as the Instrumen-
tation Ground. If an instrumentation ground reference does not exist in the installation, an earth ground
electrode should be established with an independent grounding rod or groundgrid mesh. Grounding con-
nections are described in
.
