3. Output 1** (mechanical relay Output Module)
-Used when Load permissive is integrated to prohibit product loading when the injector is in alarm, or when
the ProPAC-3 power is OFF.
4. Output 2*** (AC Solid State, DC Solid State or Mechanical Relay Output Module)
-Used when a confirmation pulse is desired (used primarily to detect a product pulser failure)
-Confirmation pulse typically provided to electronic preset or PLC
5. RS-485 Serial Communications ****
*I/O modules for the DC Product Pulse (Input 1), and the Confirmation Pulse (Output 2) must be special
ordered
(nonstandard).
**Connector P2 pin 3 (-) and pin 4 (+) are used for the Permissive Output wiring. Please note polarity
considerations.
***Connector P2 pin 7 (-) and pin 8 (+) are used for Confirmation Output wiring. Please note polarity
considerations.
*****Connector P7 RS-485. Shielded Belden cable must be used.
Note 1:
When converting from a PAC-3 to a ProPAC-3. Only the two (2) red wires should be connected to
pins 1 and 2 on the Test connector P1. Pins 3 and 4 are used for future purposes. If a lighted pushbutton
is installed on the ProPAC-3, disconnect the black and white wires. Place wire nuts on the end of each
wire to prevent electrical shorting. Installing of the black and white wires for the pushbutton, on
connector P1 pin 3 and 4, may cause damage to the injector electronics. P1 - 1,2 are not ac output on the
ProPAC-3. Lighted Pushbutton can be powered off the Output connector P2-5, 6 a dual output module
will need to be installed in Output 2 module location.
Note 2: I/O module selections different for the modules provided on the standard product need to be special
ordered with the original purchase order for ProPAC-3 injectors. However all I/O modules are field
replaceable.
