NCK alarms/ISO alarms
2101
NCK battery alarm
Definitions:
The undervoltage monitoring (2.4 - 2.6 V) of the NCK battery has responded during cyclic operation.
Reaction:
Alarm display.
Remedy:
If the NCK battery is replaced without interrupting the power supply, no data will be lost. This means
that production can continue without taking any further steps. (A buffer capacitor on the NCK holds
the supply voltage for at least 30 minutes and the battery can be replaced within this time even when
the control is switched off).
Program Continuation:
Clear alarm with the Delete key or NC START.
2102
NCK battery alarm
Definitions:
The undervoltage monitoring (2.4 - 2.6 V) of the NCK battery was detected during system power-up.
Reaction:
NC not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
Please inform the authorized personnel/service department. Pull out the battery/fan unit from the NC
module and replace the battery (type: lithium battery with lead, size 1/2 AA, 850 mAh, min. 3.2 V).
The system must then be reinitialized because it must be assumed that data has been lost in the buffered RAM during the last power-off phase as a result of insufficient supply voltage (refer to Section
2.2 in the Installation and Start-up Guide for the procedure).
The following data might have been corrupted or entirely lost:
- NC machine data
- Drive machine data
- Option data
- Setting data
- User variable
- Global subroutines
- Cycles and macros, as well as
- PLC machine data
- PLC basic program
- PLC user program, and all
- PLC user data
User data in the NCK and PLC (e.g. tool and workpiece data) that have been altered by the manufacturing process since the last data backup must be updated manually to match the present machine
status!
Program Continuation:
Switch control OFF - ON.
2110
NCK temperature alarm
Definitions:
The temperature sensor has reached the response threshold of 60 degrees C +/- 2.5 degrees C.
Reaction:
Alarm display.
Remedy:
In order to reset the sensor, the temperature must be reduced by 7 degrees C.
Program Continuation:
Clear alarm with the Delete key or NC START.
2120
NCK fan alarm
Definitions:
The fan consists of a 26 V DC motor with electronic commutator (rated speed: approx. 8700 rpm). The
commutator signal is used for speed monitoring, response speed: < 7500 rpm.
Reaction:
Alarm display.
Remedy:
Please inform the authorized personnel/service department. The unit with the fan and NCK battery
must be replaced.
Program Continuation:
Clear alarm with the Delete key or NC START.
