Replacing the Scanner Module within a System
The scanner can be replaced while the system is mounted to a panel (or DIN rail).
1.
Remove power. See important note on page 7.
2.
Remove the DeviceNet cable from the scanner by removing the DeviceNet
connector.
3.
Remove the upper and lower mounting screws from the scanner (or open
the DIN latches using a flat-blade screwdriver).
4.
On the scanner to be replaced and the right-side adjacent module (or end
cap if the scanner is the last module in the bank), move the bus levers to the
right (unlock) to disconnect the scanner from the adjacent modules.
5.
Gently slide the disconnected scanner module forward.
If you feel excessive resistance, make sure that you disconnected the
scanner from the bus and that you removed both mounting screws (or
opened the DIN latches).
.
6.
Before installing the replacement scanner, be sure that the bus lever on the
right-side adjacent module is in the unlocked (fully right) position.
7.
Slide the replacement scanner into the open slot.
8.
Connect the scanner and modules together by locking (fully left) the bus
levers on the replacement scanner and the right-side adjacent module or end
cap.
9.
Replace the mounting screws (or snap the scanner onto the DIN rail).
10.
Replace the DeviceNet cable on the scanner by attaching the connector to
the scanner.
TIP
It may be necessary to rock the scanner slightly from
front to back to remove it, or, in a panel-mounted
system, to loosen the screws of adjacent modules.
