6.5 OUTPUT SWITCH WIRING - The Power Supply Module is made to accept an industry standard
0.6 inch Output Module. The following modules are available from Altronic:
691124 This custom module has two uses: connection to a Murphy fuel valve and directly
grounding a C.D. ignition system.
A) Use in position OUT 1 to connect to a C.D. ignition type Murphy fuel valve.
Connect terminals 3 and 8 of the fuel valve to the Power Supply Module terminals
marked F1 (FV1) and F2 (FV2).
B) Use in position OUT 2 to directly ground-out (stop) a C.D. ignition system. Wire
the C.D. ignition shutdown lead and ignition ground to the Power Supply Module
terminals marked I+ (IGN+) and I! (IGN!) observing the proper polarity for the
ignition system. DO NOT connect directly to the ignition system common coil
ground.
691125 This module is rated for 5-48 Vdc, 5.0 A. and may be used in any of the four output
slots OUT 1 through OUT 4.
NOTE: Use this module if it is desired to interrupt the DC supply to DC-powered
ignition systems such as Altronic CD1, CPU-90, II-CPU or DISN.
691056 This module is rated for 5-60 Vdc, 2.0 A. and may be used in any of the four output
slots OUT 1 through OUT 4.
691066 This module is rated for 5-200 Vdc, 0.67 A. and may be used in any of the four
output slots OUT 1 through OUT 4.
691065 This module is rated for 24-280 Vac, 2.0 A. and may be used in any of the four
output slots OUT 1 through OUT 4. NOTE: Other industry standard 0.6 inch
modules may be used as required.
6.6 RS-485 COMMUNICATIONS WIRING - There are two RS-485 communication ports available
on the DE-2500 system.
- Port 2 is for connection to an optional Altronic DSM device.
- Port 3 is for RS-485 serial communication to a PC (personal computer) or a PLC.
Use a two conductor shielded cable of fine gauge stranded wire and connect the wires for port
2 to the terminals marked "A2" and "B2" and the shield wire to terminal “S2". The wiring for
port 3 connects to the terminals marked “A3", ‘B3" and “S3". Connect to the other
communication devices "A" to "A"(!) and "B" to "B"(+). Connect the shield wire to the DE-2500
system ONLY.
6.7 SENSE ROTATION INPUT - Terminals marked IGN IN and PU IN on the Power Supply Module
are used by the DE-2500 system to detect either engine rotation or ignition system firings. This
input monitors voltage signals such as those seen on either the ignition 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 MAGNETIC PICKUP INPUT MUST BE USED FOR APPLICATIONS ENABLING THE
OPTIONAL AUTO START FUNCTION.
NOTE: An installation may use only one of the terminals IGN IN or PU IN.
