1.1 About This Reference Guide and This MILRAIL™
Simple Loop Rail System Controller
BNRUSU01.C01 0000335200 B.2 A.3 2/4/21 3:13 PM Released
This controller reference guide explains how to manage and troubleshoot your MILRAIL™ sim-
ple loop rail system controller. It is for supervisors involved in production oversight and mainte-
nance technicians involved in the troubleshooting of the system. A separate operator guide,
MKRUSO01, explains routine operation.
WARNING: Careless use — can cause death or serious injury and property damage.
�Read the machine manuals before you install, operate, service, or clean
the machine.
The staff at Milnor configured your MILRAIL™ simple loop rail system controller interface to
represent your unique rail system. Users are not responsible for configuring or programming the
controller.
1.1.1 Rail System Terminology
BNRUSO02.C02 0000332313 B.2 A.3 A.6 2/5/21 9:33 AM Released
The following list of terms can help you identify the different parts of your rail system.

Pellerin Milnor Corporation 3
Figure 1. Parts of the Mast LiftSlings— Bags full of goods that will be dis-
charged to the CBW®washer’s chute. Slings
are also commonly referred to as bags.
Mast Lift— The device that lifts slings and
transfers them to the rail loop. It consists of
the carriage, the flight bar, and the floor scale.
The mast lift is also commonly referred to as
the elevator. The mast lift has four positions.
See Section 1.1.2 .
Carriage (item A in Figure 1 )— The piece of
rail on the mast lift that holds the flight bar
until it transfers the flight bar to the rail loop.
Flight Bar (item B in Figure 1 )— The device
used to carry a sling along the rail loop. The
operator manually attaches a sling to the
flight bar. The flight bar is also commonly re-
ferred to as the trolley.
Floor Scale (item C in Figure 1 )— A scale
built into the bottom of the mast lift used to
weigh goods.
PVC— An optional device used to raise slings
from a low rail to a higher rail on the rail
loop. PVC stands for Pneumatic Vertical
Conveyor.
Discharger— The device that discharges goods from a sling to the CBW®washer’s chute.
Stop— A device used to temporarily stop and allow the progression of a sling along the rail,
break the momentum of a fast-moving sling, or hold a sling in a particular position (such as
on the discharger).
Buffer— A stop used to temporarily hold one or more slings, to prevent slings from progress-
ing when a line (or device, such as discharger) is already full. For example, the full bag buffer
prevents slings from entering the full bag storage line when the full bag storage line is full.
Lift Bar— A device located before a stop, which the controller uses to determine if a line is
full.
Empty Bag Buffer— A storage location on the rail loop where the flight bar carrying an empty
sling waits after the sling discharges its goods. Here, the operator removes the empty sling
from the flight bar, and the flight bar waits to be retrieved by the mast lift’s carriage.
Full Bag Buffer— A storage location on the rail loop where slings transferred from the mast
lift to the rail loop wait to enter the full bag storage line.
Full Bag Storage Line— A storage location on the rail loop where slings wait to enter the
discharger.
1.1.2 The Mast Lift Positions BNRUSO02.C03 0000335077 B.2 A.3 A.4 2/5/21 9:57 AM Released
The mast lift has four different positions, as explained below. The following figure shows an ex-
ample rail system layout with the different mast lift positions.

sling to the flight bar. At the safety level,
the system transitions to automatic mode.
D...Bottom level— The lowest lift position,
where the operator attaches a sling to a
flight bar. This position is also commonly
referred to as the loading level.

2.2 To Edit and Delete Sling Data
BNRUSO01.T04 0000333560 B.2 A.4 A.10 2/5/21 10:33 AM Released
Slings use the same category and customer data as the previous sling, until you change this infor-
mation manually. If you need to update the category or customer data for the slings, use the fol-
lowing instructions to edit the sling’s data. You can edit a sling’s data at the mast lift, or after the
sling has already entered the rail loop. Furthermore, if a sling accidentally opens and spills goods,
you can delete a sling’s data.
To edit or delete sling data:
1. Touch a sling icon to edit its data. The Edit Sling Data window appears, shown in the follow-
ing figure, which lists the current category, customer, weight, and destination data.

ter the discharger. On rail systems with the op-
tional PVC, this is where the sling waits to enter
the PVC buffer.
X3 X33 Empty bag buffer—
Lift bar lifted
On rail systems with two empty bag buffers, this
input is made when an empty sling passes or is
present on the second empty bag buffer lift bar

or
PVC buffer—Bag at
stop
or
Spare/unused
(the empty bag buffer closest to the mast lift).
There is no space for an empty sling on the sec-
ond empty bag buffer when this input is made.
On rail systems with the optional PVC, this input
is made when a sling is at the PVC buffer (ac-
tuates the proximity switch at the PVC buffer
stop), where a sling waits to enter the PVC.
This input is unused on rail systems that do not
include these options.
X4 X34 PVC— Carriage at
bottom
This input is made when the PVC actuates the
“bottom level” proximity switch. This input is
unused on rail systems without the optional
PVC.
X5 X35 PVC— Carriage at top This input is made when the PVC actuates the
“top level” proximity switch. This input is un-
used on rail systems without the optional PVC.
X6 X36 PVC— Bag on carriage This input is made when a sling actuates the
“bag on carriage” proximity switch on the PVC
carriage. This input is unused on rail systems
without the optional PVC.
X7 X37 Extra empty bag stop This input is used as an additional empty bag
stop on some rail systems.
X0 X40 Bag entered full bag
buffer (Time reset 1)
This input is made when a sling passes the prox-
imity switch before the full bag buffer lift bar
(X15). This input ensures the current sling is set-
tled before the mast lift can transfer a new sling
to the full bag buffer.
X1 X41 Bag entered full bag
storage (Time reset 2)
This input is made when a sling passes the prox-
imity switch before the full bag storage lift bar
(X31). This input ensures the current sling is set-
tled before the full bag buffer can transfer a new
sling to the full bag storage line.
