ADDENDUM I
Overview
This document outlines the setup of the Postal Meters, Weight Calculation
and Operation of Postal Metering on the GBR 420T.
Note: The order of postal meters to weight was reversed at 26412.044 on
the GBR420
GBR 420 and GBR438/420T prior to 26412.044(Aug. 2001):
LOW to High, Postal Meter 1 to Postal Meter 3.
GBR438/420T after 26412.044(Aug. 2001):
HIGH to Low, Postal Meter 1 to Postal Meter 3 to allow Postal Meter 1,
Postal Meter Divert, to divert an over weight/size package first before the
meters.
Note: Revised from the GBR 438 document: n4wght1.doc.
Installation
• The Postal Meter kit uses existing Input/Output(IO) points in the
GBR420T and an existing cable kit and normally operates:
• Postal Meter Divert(Test point “Postal Meter Divert”, Rack1:Point19)
is Postal Meter 1(PM1).
• Select Station 7(Test point “Separation Sol #7”, Rack1:Point4) is
Postal Meter 2(PM2).
• Select Station 8(Test point “Separation Sol #8”, Rack1:Point6) is
Postal Meter 3(PM3).
• If you use Stations 7 and 8, there are alternate IO points that can be used,
call the factory.
• In general the Postal Meters are driven by 24VDC, 3AMP output
modules. 24VDC power generally comes from the inserter, but may
come from the GBR420T. If there are two power supplies, care must be
taken not to cross connect them.
• General installations use 1 or 2 postal meters and we normally use
GBR420T postal meter 2 and 3 leaving postal meter 1, Postal Meter
Divert, to be used as a postal meter or an oversize divert station.
• The actual order of the meters after the end of the Inserter should be Hi to
Lo weight, PM1, PM2, PM3.
• The Postal Meters must be positioned after the last index position of the
Inserter and all meters must be stacked as close as possible together.
Operation
• The GBR420T tracks the pack only to the last index position of the
inserter. The GBR420T actually disables the meters which are not to be
used leaving the one meter enabled to meter the pack.
• The GBR420T uses the inserter degree encoder to provide “fine timing”
by degrees of the disable/enable signal to the Postal Meters.
The “ON At” degree must come AFTER the Logical Shift(90 Deg.) of the
pack data in the GBR420T inserter software module. The “OFF At” degree
must come BEFORE the next Logical Shift(90 Deg.) of the pack data in the
GBR420T
inserter software module. This cycle should occur between 100 and 80
degrees.
• Only one pack can traverse the meters at any time.
Setups
Lineread, Barread Setup:
• Postal Meter Divert Enable(Postal Meter 1).
• Select Postal Meter Divert Enable “ON”, to operate from a read mark
ONLY.
• Select Postal Meter Divert Enable “OFF”, to operate from Weights
ONLY.
Inserter Setup:
Postal Meter By Weight Enable
• Check ON to enable Postal Meters
Inserter Setup 2:
Postal Meter Divert(Postal Meter 1)
• Enter Meter “ON AT:’ in degrees, 0 to 350. After 90 degrees.
