2.8.3 Checking the Indicator LEDs on the Solenoid Bank (SIPLACE JTF-S)
Checking the Indicator LEDs on the Solenoid Bank (SIPLACE JTF-S)
The feeder includes a bank of at least fi ve solenoids that control the pneumatic functions (see figure "
Indicator LEDs on Solenoids and Pneumatic Tube Connection"). Each solenoid includes an LED that
lights when that solenoid is active. These can also be helpful as you troubleshoot the feeder.

2.8.4 Start-Functions and Error Conditions to SIPLACE (SIPLACE JTF-S)
Start-Functions and Error Conditions to SIPLACE (SIPLACE JTF-S)
Different versions of the feeder behave differently on start-up. This depends mainly on the communica-
tions mode and firmware version (see "2.8.5 Troubleshooting Charts SIPLACE JTF-S" [ ➙ 71]
There are two points where the start-up functions may be different:
▪ Power-up and initialization
▪ First index
In order to troubleshoot a feeder, you need to understand these differences. Begin by referring to "2.8.5
Troubleshooting Charts SIPLACE JTF-S" [ ➙ 71] to identify the communications mode. Next, check the
table below to identify the start-up functions for the unit you are working on.
Error Conditions Reported to Host Machine
In the current version of the feeder, there is only one output signal or line for Error. However, there could
be eight separate conditions that might trigger the Error output. If the feeder reports an Error to the host,
the cause could be any of the following:
On power-up, manu-
al initialization is re-
quired. Set conveyor
speed manually. (El-
ev button for fast- or
the two Index Buttons
together for slow
speed).
On power- up,
feeder initializ-
es automati-
cally.
After initiali-
zation, tray
elevator au-
tomatically
moves up.
Feeder auto-
matically in-
dexes fi rst
tray.

General Problems
To recover from an exchange error:
► Identify the cause of the error, warped or clamped trays.
► Check the blinking pattern on the orange LED and compare with the list below and the troubleshoot-
ing chart.
► Correct the problem (in most cases this means remove the tray from the conveyor).
► Press the Stop button followed by the Reset button.
⇨ The orange LED should stop fl ashing. If it does not, repeat the first three steps. If the error persists,
continue trouble shooting using the charts on next pages. If error still there, contact vendor.
⇨ When the orange LED stops fl ashing, the feeder is ready to resume normal operation.

Problem Possible Cause Solution
On power-up, the feeder will not
operate. There are no lights on
the panels or sensors.
The feeder may not be getting
power.
► Be sure the feeder is plugged
into the assembly machine.
► Unplug the cable and check
for 24V DC on pins 1 and 2.
► Be sure the host machine is
on and not in an E-Stop con-
dition.
► Check the voltage reaching
the feeder.
► The motherboard in the feed-
er may be bad. Try operating
the feeder on the bench. See
the instructions at the begin-
ning of this section.
Simple or Intermediate communi-
cations mode –
The feeder will not initialize (all
operator LEDs on)
The feeder must be initialized
manually.
► For Fast conveyor speed,
press the elevator button. For
slow speed, press Index 1
and Index 2 buttons together.
The EPROM (U3) may be bad. ► Replace the microcontroller.
Use an IC puller and an anti-
static strap.
The motherboard may be bad. ► Replace the motherboard.
