Run Errors
Are classified as non-fatal but requires an operator's attention. When an error is
generated the attention relay operates and subsequently any remote device connected
to it. In addition the Run Error LED
detector is fitted with the Reports/Logs package the errors can be accessed in the Run
Error menu "View errors". All errors are described as either passive (PSV), active
(ACT) or as an event (EVT) the date & time accompany errors.

Solution
1. Complete a PV Test.
1. Check the PEC for
blockage.
2. Check PEC is
working.
3. Check pack flow
length entry is adequate,
ensuring an allowance is
made for pack skewing.
4. Ensure correct belt
speed is entered.
1. Check reject delay
and dwell time settings.
1. Decrease belt speed.
2. Change filter resistors
to lower value. Refer to
"Belt Speed"
the "Configuration &
Setup" section of this
manual
1. Increase belt speed.
2. Change filter resistors
to higher value. Refer to
"Belt Speed"
the "Configuration &
Setup" section of this
manual
1. Reduced the reject
dwell time.
2. Improve the pack
pitch.
3. If the reject is a
retracting band or
lift/drop flap, change the
reject mode to pulse
extension.
1. Enable the reject
relay using the Reject
enable command.
