Rail Width Adjust - Vitronics Soltec XPM2 Technical Reference Manual

RAIL WIDTH ADJUST

OPERATION:
Run the Manual rail adjust within the Oven Control Program. NOTE: This operation may require a password.
Manual rail adjust can be activated by clicking on the rail width adjust icon,
OR
by selecting Setup, Parameter, Customize, Manual Rail from the menu bar.
Test Procedure
1. Enable the manual rail adjust.
2. Select the rail to move if the oven has more then one rail adjust axis installed. The manual in/out rail switch is
a momentary 3 position rotary switch with a spring return to the center position and the center position is the
off position. None of the rails will move until the manual in/out switch is rotated and held in one direction.
The rail controller (A42) is a stand-alone controller that executes commands sent by the DI board through
RS485 communication. The rail controller (A42) only activates one of the rail direction relays (A1-K23 through
A1-K26) if the corresponding limit switch input is on or present. The rail controller (A42) activates the enable
output relay A1-K22 one second after one of the rail direction relays (A1-K23 through A1-K26) has been set.
3. Turn the rail in/out button in one direction. If the rail motor does not turn, turn the button in the other direction.
If the motor still does not turn, refer to the Oven Schematics and perform the following test procedure:
·
Disable the manual rail adjust.
·
Verify that the run status led on the rail controller (A42) is flashing. If the led is not flashing then there is a
problem with the rail controller board (A42).
·
Verify that the rail controller (A42) is firmly seated into the A1 board. If the run status led is not flashing
then the rail controller (A42) needs to be replaced.
·
If the run status led is flashing then verify that the cable from connector P3 on the front of the DI board to
connector P48 on the A1 board is installed correctly and that there are no loose wires on either connector.
·
Verify that the COM3 RXD and COM3 TXD leds on the front of the DI board flash periodically to indicate
that there is RS485 communication activity from the DI board to the rail controller (A42) and other boards
connected to the RS485 network.
·
The rail controller (A42) will not activate any of the rail output relays without RS485 communications being
initiated from the DI board.
·
Verify that the rail limit switch input status indicators are on on the rail controller (A42).
