RS-485 COMMUNICATIONS WIRING
•
Port 2 is for communication between the display and terminal boards.
•
Port 3 is for RS-485 serial communication between the computer mod-
ule and the HMI.
These should not be connected for normal operation.
7.10 SENSE ROTATION INPUT
Terminals marked IGN IN and PU IN on the Power Supply Module are used by
the DE-3000+ system to detect either engine rotation or ignition system firings.
On applications using multiple terminal board assemblies, the T+ terminal on the
second terminal board (the one not directly connected to the power supply) can
be used to add a second RPM value. The T+ input is only for use with magnetic
pickups. This input monitors voltage signals such as those seen on either the igni-
tion shutdown lead or a magnetic pickup monitoring an engine-mounted gear.
•
The IGN IN terminal connects to the positive (+) C.D. ignition shutdown lead.
•
The PU IN terminal connects to one magnetic pickup input; the other pickup
wire connects to the minus (−) terminal on the Power Supply Module.
•
The T+ terminal connects to one magnetic pickup input; the other pickup
wire connects to the terminal on the terminal module.
THE MAGNETIC PICKUP INPUT
MUST
BE USED FOR APPLICATIONS ENABLING
THE OPTIONAL AUTO START OR OEM ENGINE CONTROL FUNCTION.
8.0 HAZARDOUS AREA OPERATION
8.1 The DE-3000+ system is CSA-certified for CLASS I, DIVISION 2, GROUPS C
and D areas when mounted in a suitable enclosure.
In addition, the following requirements must be met (refer to NFPA standard no. 493):
•
The low voltage sensor switch wires within the panel enclosure must
be kept at least two (2) inches away from other wiring. Run the sensor
switch wires leaving the panel in a separate conduit from all other wiring
and keep them separate
•
Wiring to the sensors must have a grade of insulation capable of with-
standing an AC voltage of 500 volts RMS.
•
Sensor wires must be run in separate conduits and junction boxes from high
voltage wires such as ignition, fuel valve, and other high voltage wiring.
NOTE: AN INSTALLATION MAY USE ONLY
ONE OF THE TERMINALS IGN IN, PU IN,
OR T+.
WARNING: SUBSTITUTION OF COMPO-
NENTS MAY IMPAIR INTRINSIC SAFETY
AND/OR SUITABILITY FOR CLASS I, DIV.
2, GROUPS C AND D. DO NOT DISCON-
NECT EQUIPMENT IN DIV. 2 ENVIRON-
MENT UNLESS POWER IS SWITCHED
OFF OR THE AREA IS KNOWN TO BE
NON-HAZARDOUS.
