b.
Remove the installed jumper on the first divert box only to enable th
e “missing bearing” sensor
(requires the “missing bearing” fork sensor to be connected to the divert box).
c.
If IN 8 is ever in the LOW state while the Divert #1 pin sensor is HIGH (indicating that a bearing is
missing), the divert box will send a “missing bearing” fault by setting OUT 1 HIGH.
d.
The system PLC should stop the sorter and throw a fault to the HMI on receiving a “Missing
Bearing Fault” signal. Divert boxes do not change their operating mode or stop d
iverting when a
“Missing Bearing Fault” is set.
e.
The “missing bearing” fork sensor must be installed on the same physical divert that is wired to
Divert #1, because the monitoring functionality also uses the Divert #1 pin sensor.

3.
The
“Reset
A
ll Faults”
input is used both as a reset signa
l and as a “heartbeat”
signal to let the divert
box know when the sorter is running.
a.
The divert box is expecting a 250ms HIGH, then 250ms LOW, continuous pulse only when the
sorter main drive is running.
b.
The divert box only sets faults and monitors bearing sensors when it is receiving a pulse signal.
Lack of the pulse signal
on the “Reset All Faults” input
will cause all diverts
to become inoperative.
c.
Hold the
“Reset all Faults”
signal continuously HIGH (connected to the system start button) to
reset all faults. The divert box requires a 1 second minimum pulse to trigger the fault reset. All
faults latch and will only be cleared by triggering the fault reset.
Removing power from the divert box will NOT clear faults.
