Mailbox/Sorter Interlocks
The Mailbox/Sorter has four (4) pairs of interlock switches:
• Two Docking Interlocks that detect when the Decurler is connected to the basic machine.
• Decurler Front Cover Interlock
• Mailbox/Sorter Front Cover Interlock
Figure 1 Interlock Switch locations for the Mailbox/Sorter
The Decurler Front Cover Interlock is actually two switches. When the cover is off, one pole of
t
his
switch disconnects +24 VDC supply voltage from the Decurler Stepper Motor. The other
switch and all of the remaining interlock outputs are all normally at +5 VDC, but are grounded
when opened. The microcontroller on the Mailbox/Sorter Control PWBA reads the voltage sig-
nals. An open interlock causes the microcontroller to send a message to the IOT CPU PWBA,
inf
orm
ing it of the interlock condition. An appropriate message displays on the machine User
Interface.
