Key Protect Level
When the key-protect switch is set to ON, it is possible to prevent setting errors by prohibiting the use of certain operation keys by specifying the
key protect level (KP-1 to KP-7).
The key protect indicator is lit while the key-protect switch is set to ON.
* Changing mode to Timer/Twin Timer Selection Mode or Function Setting Mode.
Self-diagnostic Function
The following displays will appear if an error occurs.
*1. This includes times when the life of the EEPROM has expired.
*2. The normal display and
e3
will appear alternately.
When the Reset Key is pressed,
e3
will no longer be displayed even if the alarm set value is exceeded. (Monitoring is possible, however, because the Timer will
continue without clearing the output ON count.)
