AR16 Power Supply Module: The AR16 Power
Supply Module sends 24 VDC Control Voltage to the
Combined I/O and Stepper Modules on an internal bus.
The AR16 Module also sends 24 VDC Supply Voltage
on wire 303 and a common on wire 302 to the Stepper
Drive Modules to operate the Dynamic Scale Motors.

Single Flash - Module is in “reset” mode.
Blinking - Module is in preoperational mode.
On - Module is in “Run” mode.
Red LED “e”:
Off - Module not connected or everything is
“OK.”
Double Flash - Indicates one of the following
conditions:
1. Bus controller power supply is
