System software recovery

1 st recovery method
Forced cooling is required if the ambient temperature is higher than 30 °C.
See NYCe 4000 Standard Housings and Accessories manual for fan units
that mount on the system housing.
The NY4114 MCU is a state-of-the-art hardware design and incorporates
programmable logic and runs an on-board Operating System. Many checks
are executed at start-up for module validation and operation. Some detected
errors cannot be repaired and are reported by a red continuous lit "MCU"
LED. Other errors may possibly be recovered and are reported by orange
flashing "MCU" LED, see
WARNING
● Make sure power supplies are switched off before installation or removal
of the MCU.
● Do not apply power until the MCU module is installed.
WARNING
● Comply with all ESD protective measures while working with modules
and components. Avoid electrostatic discharges.
You always start the MCU in the so-called "recovery mode". Depending on
the (unknown) cause of the problem, two methods are available to return the
MCU to a operational state. The first method preserves the stored
configuration tables and data in the flash memory. The second method
erases all data in the flash memory.
While the MCU is in recovery mode, the node is not visible in the
tree view of the NYCe 4000 tools.
Before you begin
● Close all NYCe 4000 tools.
● Close all motion applications.
Do the following steps to force the MCU to start in "recovery mode".
1. Power-down the MCU and remove the MCU from the node.
1.1 Switch off all power supplies and wait until all module LEDs are
off.
1.2 Disconnect the network connection(s) to the NY4114 module.
1.3 If the two screws that hold the NY4114 module in the slot of the
system housing are tightened, loosen them.
1.4 Gently pull the NY4114 module out of the slot of the system
housing.
2. Locate the jumper block on the module and put a standard 0.1" jumper
on the indicated pins.

Damage to components may occur if power
is applied during installation or removal.
Damage to components may occur due to
